UNIVERSAL DISPLAY CORP PA

1. BUSINESS:

Universal Display Corporation and its subsidiaries (the Company) is a leader in the research, development and commercialization of organic light emitting diode (OLED) technologies and materials for use in display and solid-state lighting applications. OLEDs are thin, lightweight and power-efficient solid-state devices that emit light and can be manufactured on both flexible and rigid substrates, making them highly suitable for use in full-color displays and as lighting products. OLED displays are capturing a growing share of the display market, especially in the mobile phone, television, monitor, wearable, tablet, notebook and personal computer, augmented reality (AR), virtual reality (VR) and automotive markets. The Company believes this is because OLEDs offer potential advantages over competing display technologies with respect to power efficiency, contrast ratio, viewing angle, video response time, form factor and manufacturing cost. The Company also believes that OLED lighting products have the potential to replace many existing light sources in the future because of their high-power efficiency, excellent color rendering index, low operating temperature and novel form factor. The Company’s technology leadership, intellectual property position, and more than 20 years of experience working closely with leading OLED display manufacturers are some of the competitive advantages that should enable the Company to continue to share in the revenues from OLED displays and lighting products as they gain wider acceptance.

The Company’s primary business strategy is to (1) develop new OLED materials and sell existing and new materials to product manufacturers of products for display applications, such as mobile phones, televisions, monitors, wearables, tablets, portable media devices, notebook computers, personal computers and automotive applications, and specialty and general lighting products; and (2) further develop and either license or otherwise commercialize the Company’s proprietary OLED material, device design and manufacturing technologies to those manufacturers. The Company has established a significant portfolio of proprietary OLED technologies and materials, primarily through internal research and development efforts and acquisitions of patents and patent applications, as well as maintaining long-standing, and establishing new relationships with world-class universities, research institutions and strategic manufacturing partnerships. The Company currently owns, exclusively licenses or has the sole right to sublicense more than 6,000 patents issued and pending worldwide.

The Company manufactures and sells its proprietary OLED materials to customers for evaluation and use in commercial OLED products. The Company also enters into agreements with manufacturers of OLED display and lighting products under which it grants them licenses to practice under the Company’s patents and to use the Company's proprietary know-how. At the same time, the Company works with these and other companies that are evaluating the Company's OLED material, device design and manufacturing technologies for possible use in commercial OLED display and lighting products.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

Interim Financial Information

In the opinion of management, the accompanying unaudited Consolidated Financial Statements have been prepared in accordance with the requirements of the Securities and Exchange Commission for interim financial reporting and contain all adjustments (consisting of only normal recurring adjustments) necessary to present fairly the Company’s financial position as of June 30, 2024 and results of operations for the three and six months ended June 30, 2024 and 2023, and cash flows for the six months ended June 30, 2024 and 2023. While management believes that the disclosures presented are adequate to make the information not misleading, these unaudited Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements and the notes thereto in the Company’s latest year-end Consolidated Financial Statements, which are included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023. The results of the Company’s operations for any interim period are not necessarily indicative of the results of operations for any other interim period or for the full year.

Principles of Consolidation

The Consolidated Financial Statements include the accounts of Universal Display Corporation and its wholly owned subsidiaries, UDC, Inc., UDC Ireland Limited (UDC Ireland), Universal Display Corporation Hong Kong, Limited, Universal Display Corporation Korea, Y.H. (UDC Korea), Universal Display Corporation Japan GK, Universal Display Corporation China, Ltd., Adesis, Inc. (Adesis), UDC Ventures LLC, OVJP Corporation (OVJP Corp) and OLED Material Manufacturing Limited (OMM). All intercompany transactions and accounts have been eliminated.

Reclassification of Prior Year Presentation

Certain prior year adjustments to reconcile net income to net cash provided by operating activities have been reclassified on the Consolidated Statements of Cash Flows to conform to the current year presentation. Stock-based compensation activity has been consolidated and includes stock-based compensation to employees, Board of Directors, and Scientific Advisory Board.

Certain prior year adjustments have been reclassified on the Consolidated Statements of Shareholders' Equity to conform to the current year presentation. Stock-based compensation and ESPP activity, net of taxes withheld has been consolidated and includes issuance of common stock to employees, shares withheld for employee taxes, issuance of common stock to Board of Directors and Scientific Advisory Board, cancellation of restricted stock units and issuance of common stock to employees under an ESPP.

Management’s Use of Estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principles (GAAP) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The estimates made are principally in the areas of revenue recognition including estimates of material unit sales and royalties, the useful life of acquired intangibles, lease liabilities, right-of-use assets, the use and recoverability of inventories, intangibles, investments and income taxes including realization of deferred tax assets, stock-based compensation and retirement benefit plan liabilities. Actual results could differ from those estimates.

Inventories

Inventories consist of raw materials, work-in-process and finished goods, and are stated at the lower of cost, determined on a first-in, first-out basis, or net realizable value. Inventory valuation and firm committed purchase order assessments are performed on a quarterly basis and those items that are identified to be obsolete or in excess of forecasted usage are written down to their estimated realizable value. Estimates of realizable value are based upon management’s analyses and assumptions, including, but not limited to, forecasted sales levels by product, expected product lifecycle, product development plans and future demand requirements. A 12-month rolling forecast based on factors, including, but not limited to, production cycles, anticipated product orders, marketing forecasts, backlog, and shipment activities is used in the inventory analysis. If market conditions are less favorable than forecasts or actual demand from customers is lower than estimates, additional inventory write-downs may be required. If demand is higher than expected, inventories that had previously been written down may be sold.

Fair Value of Financial Instruments

The carrying values of accounts receivable, other current assets, accounts payable and other current liabilities approximate fair value in the accompanying Consolidated Financial Statements due to the short-term nature of those instruments. The Company’s other financial instruments, which include cash equivalents and investments (excluding minority equity investments) are carried at fair value.

Minority Equity Investments

The Company accounts for minority equity investments in companies that are not accounted for under the equity method as equity securities without readily determinable fair values. The value of these securities is based on original cost less impairments, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or similar investment in the same issuer. Under this method, the share of income or loss of such companies is not included in the Consolidated Statements of Income. The carrying value of these investments is included in investments on the Consolidated Balance Sheets.

The Company’s policy is to recognize an impairment in the value of its minority equity investments when evidence of an impairment exists. Factors considered in the assessment include a significant adverse change in the regulatory, economic, or technological environment, the completion of new equity financing that may indicate a decrease in value, the failure to complete new equity financing arrangements after seeking to raise additional funds, or the commencement of proceedings under which the assets of the business may be placed in receivership or liquidated to satisfy the claims of debt and equity stakeholders. The impairment in the value of minority equity investments is included in the other loss, net line item on the Consolidated Statements of Income.

Leases

The Company is a lessee in operating leases primarily incurred to facilitate manufacturing, research and development, and selling, general and administrative activities. At contract inception, the Company determines if an arrangement is or contains a lease, and if so recognizes a right-of-use asset and lease liability at the lease commencement date. For operating leases, the lease liability is measured at the present value of the unpaid lease payments at the lease commencement date, whereas for finance leases, the lease liability is initially measured at the present value of the unpaid lease payments and subsequently measured at amortized cost using the interest method. Operating lease right-of-use assets are included in other assets on the Consolidated Balance Sheets. The short-term portion of operating lease liabilities is included in other current liabilities on the Consolidated Balance Sheets and the long-term portion is included in other liabilities on the Consolidated Balance Sheets. As of June 30, 2024, the Company had no leases that qualified as financing arrangements.

Key estimates and judgments include how the Company determines the discount rate used to discount the unpaid lease payments to present value and the lease term. The Company monitors for events or changes in circumstances that could potentially require recognizing an impairment loss.

Revenue Recognition and Deferred Revenue

Material sales relate to the Company’s sale of its OLED materials for incorporation into its customers’ commercial OLED products or for their OLED development and evaluation activities. Revenue associated with material sales is generally recognized at the time title passes, which is typically at the time of shipment or at the time of delivery, depending upon the contractual agreement between the parties. Revenue may be recognized after control of the material passes in the event the transaction price includes variable consideration. For example, a customer may be provided an extended opportunity to stock materials prior to use in mass production and given a general right of return not conditioned on breaches of warranties associated with the specific product. In such circumstances, revenue will be recognized at the earlier of the expiration of the customer’s general right of return or once it becomes unlikely that the customer will exercise its right of return.

The vast majority of revenue attributed to material sales is determined through technology license agreements and material supply agreements the terms of which are jointly agreed upon with the Company’s customers. The remaining revenue recognized is in the form of contract research services revenue earned by the Company’s subsidiary, Adesis, Inc., and the Company’s occasional material sales to smaller customers. None of the revenue recognized during the three and six months ended June 30, 2024 and 2023 resulted solely from royalty or license fee arrangements as to which there were not associated material sales.

The rights and benefits to the Company’s OLED technologies are conveyed to the customer through technology license agreements and material supply agreements. The Company believes that the licenses and materials sold under these combined agreements are not distinct from each other for financial reporting purposes and as such, they are accounted for as a single performance obligation. Accordingly, total contract consideration is estimated and recognized over the contract term based on material units sold at the estimated per unit fee over the life of the contract. Total contract consideration is allocated to material sales and royalty and licensing fees on the Consolidated Statements of Income based on contract pricing.

Various estimates are relied upon to recognize revenue. The Company estimates total material units to be purchased by its customers over the contract term based on historical trends, industry estimates and its forecast process. Management uses the expected value method to estimate the material per unit fee. Additionally, management estimates the sales-based portion of royalty revenue based on the estimated net sales revenue of its customers over the contract term.

Contract research services revenue is revenue earned by Adesis by providing chemical materials synthesis research, development and commercialization for non-OLED applications on a contractual basis. These services range from intermediates for structure-activity relationship studies, reference agents and building blocks for combinatorial synthesis, re-synthesis of key intermediates, specialty organic chemistry needs, and selective toll manufacturing. These services are provided to third-party pharmaceutical and life sciences firms and other technology firms at fixed costs or predetermined rates on a contract basis. Revenue is recognized as services are performed with billing schedules and payment terms negotiated on a contract-by-contract basis. Payments received in excess of revenue recognized are recorded as deferred revenue. In other cases, services may be provided and revenue is recognized before the customer is invoiced. In these cases, revenue recognized will exceed amounts billed and the difference, representing amounts which are currently unbillable to the customer pursuant to contractual terms, is recorded as an unbilled receivable.

Technology development and support revenue is revenue earned from development and technology evaluation agreements and commercialization assistance fees. Technology development and support revenue is included in contract research services on the Consolidated Statements of Income.

On December 2, 2022, the Company entered into a commercial patent license agreement with Samsung Display Co., Ltd. (SDC), replacing a previous license agreement that had been in place since 2018. This agreement, which covers the manufacture and sale of specified OLED display materials, was effective as of January 1, 2023 and lasts through the end of 2027 with an additional two-year extension option for SDC. Under this agreement, the Company is being paid a license fee, which includes quarterly and annual payments over the agreement term offive years. The agreement conveys to SDC the non-exclusive right to use certain of the Company's intellectual property assets for a limited period of time that is less than the estimated life of the assets.

At the same time the Company entered into the current commercial license agreement with SDC, the Company also entered into a new supplemental material purchase agreement with SDC, which lasts for the same term as the license agreement and is subject to the same extension option. This new material purchase agreement replaced a previous purchase agreement that had been in place since 2018. Under the supplemental material purchase agreement, SDC agrees to purchase red and green phosphorescent emitter materials from the Company for use in the manufacture of licensed products. This amount purchased is subject to SDC’s requirements for phosphorescent emitter materials and the Company’s ability to meet these requirements over the term of the supplemental agreement.

In 2015, the Company entered into an OLED patent license agreement and an OLED commercial supply agreement with LG Display Co., Ltd. (LG Display), which were effective as of January 1, 2015. The terms of these agreements were extended by a January 1, 2021 amendment through the end of 2025. The patent license agreement provides LG Display a non-exclusive, royalty bearing portfolio license to make and sell OLED displays under the Company's patent portfolio. The patent license calls for license fees, prepaid royalties and running royalties on licensed products. The OLED commercial supply agreement provides for the sale of materials for use by LG Display, which may include phosphorescent emitters and host materials. The agreements provide for certain other minimum obligations relating to the volume of material sales anticipated over the lives of the agreements as well as minimum royalty revenue.

In 2023, the Company entered into new long-term, multi-year agreements with BOE Technology Group Co., Ltd. (BOE). Under these agreements, the Company has granted BOE non-exclusive license rights under various patents owned or controlled by the Company to manufacture and sell OLED display products. The Company supplies phosphorescent OLED materials to BOE for use in its licensed products.

In 2019, the Company entered into an evaluation and commercial supply relationship with Wuhan China Star Optoelectronics Semiconductor Display Technology Co., Ltd. (CSOT). In 2020, the Company entered into long-term, multi-year agreements with CSOT. Under these agreements, the Company has granted CSOT non-exclusive license rights under various patents owned or controlled by the Company to manufacture and sell OLED display products. The Company also supplies phosphorescent OLED materials to CSOT for use in its licensed products.

In 2024, the Company entered into new long-term, multi-year agreements with Visionox Technology, Inc. (Visionox). Under these agreements, the Company has granted Visionox non-exclusive license rights under various patents owned or controlled by the Company to manufacture and sell OLED display products. Additionally, the Company supplies phosphorescent OLED materials to Visionox for use in its licensed products.

In 2016, the Company entered into long-term, multi-year OLED patent license and material purchase agreements with Tianma Micro-electronics Co., Ltd. (Tianma). Under the license agreement, the Company has granted Tianma non-exclusive license rights under various patents owned or controlled by the Company to manufacture and sell OLED display products. The license agreement calls for license fees and running royalties on licensed products. Additionally, the Company supplies phosphorescent OLED materials to Tianma for use in its licensed products. In 2021, the parties extended the terms of both the patent license and material purchase agreements for an additional multi-year-term.

All material sales transactions that are not variable consideration transactions are billed and due within 90 days and substantially all are transacted in U.S. dollars.

Cost of Sales

Cost of sales consists of labor and material costs associated with the production of materials processed at the facilities of the Company's manufacturing partner, PPG Industries, Inc. (PPG) and at the Company's internal facilities. The Company’s portion of cost of sales also includes depreciation of manufacturing equipment, as well as manufacturing overhead costs and inventory adjustments for excess and obsolete inventory.

Research and Development

Expenditures for research and development are charged to expense as incurred.

Patent Costs

Costs associated with patent applications, patent prosecution, patent defense and the maintenance of patents are charged to expense as incurred. Costs to successfully defend a challenge to a patent are capitalized to the extent of an evident increase in the value of the patent. Costs that relate to an unsuccessful outcome are charged to expense.

Amortization of Acquired Technology

Amortization costs primarily relate to technology acquired from Merck KGaA, Darmstadt, Germany (Merck KGaA) and BASF SE (BASF). The Merck KGaA acquisition was completed on April 28, 2023 and the BASF acquisition was completed during the year ended December 31, 2016. Acquisition costs are being amortized over a period of 10 years for the Merck KGaA and BASF patents.

Amortization of Other Intangible Assets

Other intangible assets from the Adesis acquisition are being amortized over a period of 10 to 15 years. See Note 7 for further discussion.

Translation of Foreign Currency Financial Statements and Foreign Currency Transactions

The Company’s reporting currency is the U.S. dollar. The functional currency for the UDC Ireland and UDC Korea subsidiaries are also the U.S. dollar and the functional currency for the OMM subsidiary and each of the Company's other Asia-Pacific foreign subsidiaries is its respective local currency. The Company translates the amounts included in the Consolidated Statements of Income from OMM and its Asia-Pacific foreign subsidiaries into U.S. dollars at weighted-average exchange rates, which the Company believes are representative of the actual exchange rates on the dates of the transactions. The Company's OMM subsidiary and each of the Company's other Asia-Pacific foreign subsidiaries' assets and liabilities are translated into U.S. dollars from the local currency at the actual exchange rates as of the end of each reporting date, and the Company records the resulting foreign exchange translation adjustments in the Consolidated Balance Sheets as a component of accumulated other comprehensive loss. The overall effect of the translation of foreign currency and foreign currency transactions to date has been insignificant.

Income Taxes

Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. The Company recognizes the effect of income tax positions only if those positions are more likely than not of being sustained. Recognized income tax positions are measured at the largest amount of which the likelihood of realization is greater than 50%. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs. The Company records interest and penalties, if any, related to unrecognized tax benefits as a component of tax expense.

Share-Based Payment Awards

The Company recognizes in the Consolidated Statements of Income the grant-date fair value of equity-based awards such as shares issued under employee stock purchase plans, restricted stock awards, restricted stock units and performance unit awards issued to employees and directors.

The grant-date fair value of stock awards is based on the closing price of the stock on the date of grant. The fair value of share-based awards is recognized as compensation expense on a straight-line basis over the requisite service period, net of forfeitures. The Company issues new shares upon the respective grant, exercise or vesting of the share-based payment awards, as applicable.

Performance unit awards are subject to either a performance-based or market-based vesting requirement. For performance-based vesting, the grant-date fair value of the award, based on fair value of the Company's common stock, is recognized over the service period based on an assessment of the likelihood that the applicable performance goals will be achieved, and compensation expense is periodically adjusted based on actual and expected performance. Compensation expense for performance unit awards with market-based vesting is calculated based on the estimated fair value as of the grant date utilizing a Monte Carlo simulation model and is recognized over the service period on a straight-line basis.

Recent Accounting Pronouncements

Adoption of New Accounting Standards

In June 2022, the FASB issued ASU No. 2022-03, Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions. Under this standard, a contractual restriction on the sale of an equity security is not considered in measuring the security's fair value. The standard also requires certain disclosures for equity securities that are subject to contractual restrictions. The adoption of ASU 2022-03, beginning on January 1, 2024, did not have an impact on the Consolidated Financial Statements and related disclosures.

Accounting Standards Issued But Not Yet Adopted

In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. The standard improves the reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. ASU 2023-07 becomes effective during the annual period ending December 31, 2024. The Company is evaluating the potential impact of this standard on its Consolidated Financial Statements and related disclosures.

In December 2023, the FASB issued ASU No. 2023-09, Improvements to Income Tax Disclosures (Topic 740). The standard enhances to the annual income tax disclosures to address investor requests for more information about the tax risks and opportunities present in an entity's worldwide operations. ASU 2023-09 becomes effective for annual periods beginning after December 15, 2024, and the Company is evaluating the potential impact of this standard on its income tax disclosures.

In March 2024, the FASB issued ASU No. 2024-01, Compensation - Stock Compensation (Topic 718). The standard provides guidance to reduce complexity and diversity in practice in determining whether a profits interest award is accounted for as a share-based payment. Early adoption is permitted. This guidance can be applied either retrospectively to all prior periods presented in the financial statements or prospectively to profits interest or similar awards granted or modified on or after the effective date for our application of this guidance. ASU 2024-01 becomes effective January 1, 2025, and the Company is evaluating the potential impact of this standard on its Consolidated Financial Statements and related disclosures.

12. OTHER LIABILITIES:

Other liabilities consist of the following (in thousands):

See Notes 9 and 20 for further explanation on long-term lease liabilities and long-term taxes payable, respectively.

13. EQUITY AND CASH COMPENSATION UNDER THE PPG AGREEMENT:

On September 22, 2011, the Company entered into an Amended and Restated OLED Materials Supply and Service Agreement with PPG (the New OLED Materials Agreement), which, effective as of October 1, 2011, replaced the original OLED Materials Agreement with PPG. The term of the New OLED Materials Agreement, by amendment in February 2021, runs through December 31, 2024, and thereafter is automatically renewed for additional one-year terms, unless terminated by the Company by providing prior notice of one year or terminated by PPG by providing prior notice of two years. The New OLED Materials Agreement contains provisions that are substantially similar to those of the original OLED Materials Agreement. Under the New OLED Materials Agreement, PPG continues to assist the Company in developing its proprietary OLED materials and supplying the Company with those materials for evaluation purposes and for resale to its customers.

Under the New OLED Materials Agreement, the Company compensates PPG on a cost-plus basis for the services provided during each calendar quarter. The Company is required to pay for some of these services in all cash. Up to 50% of the remaining services are payable, at the Company’s sole discretion, in cash or shares of the Company’s common stock, with the balance payable in cash. The actual number of shares of common stock issuable to PPG is determined based on the average closing price for the Company’s common stock during a specified number of days prior to the end of each calendar half-year period ending on March 31 and September 30. If, however, this average closing price is less than $20.00, the Company is required to compensate PPG in cash. No shares have been issued for services rendered by PPG since the inception of the contract.

The Company is also required to reimburse PPG for raw materials used for research and development. The Company records the purchases of these raw materials as a current asset until such materials are used for research and development efforts.

In February 2021, the Company entered into an amendment to the New OLED Materials Agreement extending the term of the agreement and specifying operation and maintenance services to be provided by PPG affiliate, PPG SCM Ireland Limited (PPG SCM), to UDC Ireland, at the Company’s manufacturing site in Shannon, Ireland that UDC Ireland’s wholly-owned subsidiary, OLED Material Manufacturing Limited (OMM), began leasing at such time for the production of OLED materials. OMM purchased the site in September 2023 and the Company amended and restated the February 2021 amendment to reflect OMM’s ownership and PPG SCM’s updated operation and maintenance services after such purchase. Facility improvements have been completed and operations commenced in June 2022. As with the initial New OLED Materials Agreement, the Company compensates PPG on a cost-plus basis for the services provided at the Shannon manufacturing facility.

The Company recorded research and development expense of $3.4 million and $2.6 million for thethree months ended June 30, 2024 and 2023, respectively, and $7.9 million and $4.6 million for thesix months ended June 30, 2024 and 2023, respectively, in relation to the cash portion of the reimbursement of expenses and work performed by PPG, excluding amounts paid for commercial chemicals.

16. STOCK-BASED COMPENSATION:

Equity Compensation Plan

On June 15, 2023, the shareholders of the Company voted to approve the Universal Display Corporation 2023 Equity Compensation Plan (the “Equity Compensation Plan”), which replaced the Universal Display Corporation 2014 Equity Compensation Plan. The Equity Compensation Plan provides for the granting of incentive and nonqualified stock options, shares of common stock, stock appreciation rights and performance units to employees, directors and consultants of the Company. Stock options are exercisable over periods determined by the Company’s Human Capital Committee, but for no longer than 10 years from the grant date. The total number of shares that may be subject to awards under the Equity Compensation Plan is equal to the shares that were available for issuance and not subject to an award under the 2014 Equity Compensation Plan at the time it was replaced by the Equity Compensation Plan, subject to adjustment with respect to shares underlying any outstanding award granted under the Equity Compensation Plan or the 2014 Equity Compensation Plan that may expire, or be terminated, surrendered or forfeited for any reason, without issuance of such shares. As of June 30, 2024, there were 1,358,380 shares that remained available to be granted under the Equity Compensation Plan. The Equity Compensation Plan will terminate on June 15, 2033.

Restricted Stock Awards and Units

The Company has issued restricted stock awards and units to employees and non-employees with vesting terms of one to five years. The fair value is equal to the market price of the Company’s common stock on the date of grant for awards granted to employees. Consistent with the accounting for equity-classified awards issued to employees, our equity-classified nonemployee share-based awards are measured at the grant date fair value. Expense for restricted stock awards and units is amortized ratably over the vesting period for the awards issued to employees and using a graded vesting method for the awards issued to non-employees.

During the six months ended June 30, 2024, the Company granted 86,035 shares of restricted stock awards and restricted stock units to employees and non-employees, which had a total fair value of $14.2 million on the respective dates of grant, and will vest over three tofive years from the date of grant, provided that the grantee is still an employee of the Company or is still providing services to the Company on the applicable vesting date.

For the three months ended June 30, 2024 and 2023, the Company recorded, as compensation charges related to all restricted stock awards and units granted to employees and non-employees, selling, general and administrative expense of $2.1 million and $2.4 million, respectively, research and development expense of $1.4 million and $1.4 million, respectively, and cost of sales of $406,000 and $451,000, respectively. For thesix months ended June 30, 2024 and 2023, the Company recorded, as compensation charges related to all restricted stock awards and units granted to employees and non-employees, selling, general and administrative expense of $4.3 million and $5.4 million, respectively, research and development expense of $2.8 million and $2.9 million, respectively, and cost of sales of $842,000 and $981,000, respectively.

In connection with the vesting of restricted stock awards and units during the three months ended June 30, 2024 and 2023,1,753 and 1,611 shares, respectively, with aggregate fair values of $271,000 and $217,000, respectively, were withheld in satisfaction of tax withholding obligations and are reflected as a financing activity within the Consolidated Statements of Cash Flows. In connection with the vesting of restricted stock awards and units during thesix months ended June 30, 2024 and 2023,33,422 and 47,964 shares, respectively, with aggregate fair values of $5.9 million and $6.6 million, respectively, were withheld in satisfaction of tax withholding obligations and are reflected as a financing activity within the Consolidated Statements of Cash Flows.

For the three months ended June 30, 2024 and 2023, the Company recorded as compensation charges related to all restricted stock units granted to non-employee members of the Scientific Advisory Board, whose unvested shares are marked to market each reporting period, research and development expense of $60,000 for both three-month periods. Such compensation charges to research and development expense were $122,000 and $127,000, respectively, for thesix months ended June 30, 2024 and 2023.

The Company has granted restricted stock units to non-employee members of the Board of Directors with quarterly vesting over a period of approximately one year. The fair value is equal to the market price of the Company's common stock on the date of grant. The restricted stock units are issued and expense is recognized ratably over the vesting period. For the three months ended June 30, 2024 and 2023, the Company recorded compensation charges for services performed, related to all restricted stock units granted to non-employee members of the Board of Directors, selling, general and administrative expense of $468,000 and $359,000, respectively. Such compensation charges to selling, general, and administrative expense were $864,000 and $714,000, respectively, for thesix months ended June 30, 2024 and 2023. In connection with the vesting of the restricted stock, the Company issued to non-employee members of the Board of Directors 5,218 and 3,304 shares, respectively, during thesix months ended June 30, 2024 and 2023.

Performance Unit Awards

Each performance unit award is subject to both a performance-vesting requirement (either performance-based or market-based) and a service-vesting requirement. The performance-based vesting requirement is tied to EBITDA and cash flow achievement, as measured over a specific performance period. The market-based vesting requirement is tied to the Company's total shareholder return (TSR) relative to the TSR of companies comprising the Nasdaq Electronics Components Index, as measured over a three-year performance period. The maximum number of performance units that may vest based on performance is three times the shares granted. Further, if the Company's performance falls below certain thresholds, the performance units will not vest at all.

During the six months ended June 30, 2024, the Company granted 69,600 performance units, of which 34,798 units are subject to performance-based vesting requirements based on three-year cumulative adjusted EBITDA,17,401 units are subject to performance-based vesting requirements based on three-year cumulative gross margin and 17,401 units are subject to market-based, TSR vesting requirements. The grant date fair value of the performance unit awards granted was $11.4 million for thesix months ended June 30, 2024, as determined by the Company’s common stock on date of grant for the units with performance-based vesting and a Monte Carlo simulation model used for the units with market-based vesting.

For the three months ended June 30, 2024 and 2023, the Company recorded selling, general and administrative expense of $2.9 million and $1.1 million, respectively, research and development expense of $1.2 million and $607,000, respectively, and cost of sales expense of $718,000 and $376,000, respectively, related to the performance units. For thesix months ended June 30, 2024 and 2023, the Company recorded selling, general and administrative expense of $5.5 million and $251,000, respectively, research and development expense of $2.4 million and $376,000, respectively, and cost of sales expense of $1.5 million and $233,000, respectively, related to the performance units.

In connection with the vesting of performance units during the six months ended June 30, 2024 and 2023,8,160 and 5,350 shares, respectively, with an aggregate fair value of $1.4 million and $775,000, respectively, were withheld in satisfaction of tax withholding obligations and are reflected as a financing activity within the Consolidated Statements of Cash Flows.

Employee Stock Purchase Plan

On April 7, 2009, the Board of Directors of the Company adopted an Employee Stock Purchase Plan (ESPP). The ESPP was approved by the Company’s shareholders and became effective on June 25, 2009. The Company has reserved 1,000,000 shares of common stock for issuance under the ESPP. Unless terminated by the Board of Directors, the ESPP will expire when all reserved shares have been issued.

Eligible employees may elect to contribute to the ESPP through payroll deductions during consecutive three-month purchase periods, the first of which began on July 1, 2009. Each employee who elects to participate will be deemed to have been granted an option to purchase shares of the Company’s common stock on the first day of the purchase period. Unless the employee opts out during the purchase period, the option will automatically be exercised on the last day of the period, which is the purchase date, based on the employee’s accumulated contributions to the ESPP. The purchase price will equal 85% of the lesser of the closing price per share of common stock on the first business day of the period or the last business day of the period.

Employees may allocate up to 10% of their base compensation to purchase shares of common stock under the ESPP; however, each employee may purchase no more than 12,500 shares on a given purchase date, and no employee may purchase more than $25,000 of common stock under the ESPP during a given calendar year.

During the six months ended June 30, 2024 and 2023, the Company issued 8,334 and 9,339 shares, respectively, of its common stock under the ESPP, resulting in proceeds of $1.2 million and $971,000, respectively.

For the three months ended June 30, 2024 and 2023, the Company recorded charges of $35,000 and $30,000, respectively, to selling, general and administrative expense, $61,000 and $54,000, respectively, to research and development expense, and $46,000 and $34,000, respectively, to cost of sales related to the ESPP equal to the amount of the discount and the value of the look-back feature. For thesix months ended June 30, 2024 and 2023, the Company recorded charges of $72,000 and $70,000, respectively, to selling, general and administrative expense, $137,000 and $125,000, respectively, to research and development expense, and $97,000 and $75,000, respectively, to cost of sales related to the ESPP equal to the amount of the discount and the value of the look-back feature.

Scientific Advisory Board Awards

During the six months ended June 30, 2024 and 2023, the Company granted a total of 1,616 and 2,366 shares, respectively, of fully vested common stock to non-employee members of the Scientific Advisory Board for services performed in 2023 and 2022, respectively. The fair value of shares issued to members of the Scientific Advisory Board was $300,000 for both six-month periods.

17. RETIREMENT PLAN BENEFIT LIABILITY:

On March 18, 2010, the Human Capital Committee and the Board of Directors of the Company approved and adopted the Universal Display Corporation Supplemental Executive Retirement Plan (SERP). The SERP is currently unfunded and includes salary and bonus as part of the plan. The purpose of the SERP is to provide certain of the Company’s key employees with supplemental pension benefits following a cessation of their employment and to encourage their continued employment with the Company. As of June 30, 2024, there were seven participants in the SERP. In December 2022, one of the participants retired and monthly SERP benefit payments commenced in January 2023. The total SERP benefit payments for thesix months ended June 30, 2024 were $1.0 million.

The Company records amounts relating to the SERP based on calculations that incorporate various actuarial and other assumptions, including discount rates, rate of compensation increases, retirement dates and life expectancies. The net periodic costs are recognized as employees render the services necessary to earn the SERP benefits.

The components of net periodic pension cost were as follows (in thousands):

18. COMMITMENTS AND CONTINGENCIES:

Commitments

Under the current research agreement with USC, the Company is obligated to make certain payments to USC based on work performed by it under that agreement, and by the University of Michigan (Michigan) under a subcontractor agreement that Michigan has with USC.

Under the terms of the current license agreement among the Company, Princeton and USC, the Company makes royalty payments to Princeton. See Note 11 for further explanation.

The Company has agreements with five executive officers and 11 senior level employees which provide for certain cash and other benefits upon termination of employment of the officer or employee in connection with a change in control of the Company. If a covered person’s employment is terminated in connection with the change in control, the person is entitled to a lump-sum cash payment equal totwo times (in the case of the executive officers) or eitherone ortwo times (in the case of the senior level employees) the sum of the average annual base salary and bonus of the person and immediate vesting of all stock options and other equity awards that may be outstanding at the date of the change in control, among other items.

In order to manage manufacturing lead times and help ensure adequate material supply, the Company entered into the New OLED Materials Agreement (see Note 13) that allows PPG to procure and produce inventory based upon criteria as defined by the Company. These purchase commitments consist of firm, noncancelable and unconditional commitments. In certain instances, this agreement allows the Company the option to reschedule and adjust the Company’s requirements based on its business needs prior to firm orders being placed. As of June 30, 2024 and December 31, 2023, the Company had purchase commitments for inventory of $38.3 million and $29.8 million, respectively.

Patent Related Challenges and Oppositions

Each major jurisdiction in the world that issues patents provides both third parties and applicants an opportunity to seek a further review of an issued patent. The process for requesting and considering such reviews is specific to the jurisdiction that issued the patent in question, and generally does not provide for claims of monetary damages or a review of specific claims of infringement. The conclusions made by the reviewing administrative bodies tend to be appealable and generally are limited in scope and applicability to the specific claims and jurisdiction in question.

The Company believes that opposition proceedings are frequently commenced in the ordinary course of business by third parties who may believe that one or more claims in a patent do not comply with the technical or legal requirements of the specific jurisdiction in which the patent was issued. The Company views these proceedings as reflective of its goal of obtaining the broadest legally permissible patent coverage permitted in each jurisdiction. Once a proceeding is initiated, as a general matter, the issued patent continues to be presumed valid until the jurisdiction’s applicable administrative body issues a final non-appealable decision. Depending on the jurisdiction, the outcome of these proceedings could include affirmation, denial or modification of some or all of the originally issued claims. The Company believes that as OLED technology becomes more established and its patent portfolio increases in size, so will the number of these proceedings.

19. CONCENTRATION OF RISK:

Revenues and accounts receivable from the Company's largest customers were as follows (in thousands):

Revenues from outside of North America represented approximately 98% ofconsolidated revenue for both three-month periods ended June 30, 2024 and 2023, and 98% and 97% for thesix months ended June 30, 2024 and 2023, respectively. Revenues by geographic area are as follows (in thousands):

The Company attributes revenue to different geographic areas on the basis of the location of the customer.

Property and equipment, net by geographic area are as follows (in thousands):

Substantially all chemical materials were purchased fromone supplier. See Note 13 for further explanation.

20. INCOME TAXES:

The Company is subject to income taxes in both the United States and foreign jurisdictions. The effective income tax rate was 19.3% and 22.4% for thethree months ended June 30, 2024 and 2023, respectively, and 19.3% and 22.6% for thesix months ended June 30, 2024 and 2023, respectively. The Company recorded an income tax expense of $12.6 million and $14.4 million for thethree months ended June 30, 2024 and 2023, respectively, and $26.2 million for bothsix months ended June 30, 2024 and 2023. The discrepancy between the statutory tax rate and the effective tax rate is primarily due to the benefit of income taxed in foreign jurisdictions partially offset by nondeductible employee compensation and U.S. international tax (GILTI and Subpart F). The effective income tax rate decreased due to a change in U.S. tax regulations associated with the ability to credit Chinese withholding taxes, as well as a change in the capitalization rules for research and development expenses.

In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent on the Company's ability to generate future taxable income to obtain benefit from the reversal of temporary differences, net operating loss carryforwards and tax credits. As part of its assessment, management considers the scheduled reversal of deferred tax liabilities, projected future taxable income, and tax planning strategies. At this time there is not sufficient evidence to release the valuation allowance that has been recorded for the New Jersey research and development credits and unrealized loss on investments. There are no indicators against the realizability of the remaining net deferred tax asset.

On December 27, 2018, the Korean Supreme Court, citing prior cases, held that only royalties paid with respect to Korean registered patents are considered Korean source income and subject to Korean withholding tax under the applicable law and interpretation of the Korea-U.S. Tax Treaty. The Company has incurred Korean withholding tax of $14.9 million for each of the years ended December 31, 2018, through December 31, 2022. Based on the Korean Supreme Court decision, a tax refund request on behalf of the Company was filed with the Korean National Tax Service (KNTS) for the entire period from January 1, 2018, to December 31, 2022. The Company received a formal rejection from the KNTS; and in May 2022 filed an appeal with the Korean Tax Tribunal. On December 18, 2023, the Company received a formal rejection from the Tax Tribunal. Anticipating the rejection of the appeal, in September 2023 the Company filed a petition to the District Court and is awaiting its decision. The Company has been advised by a prominent Korean law firm that there is a more-likely-than-not chance of success. As a result, the Company has recorded a long-term asset of $56.4 million and $60.1 million as of June 30, 2024, and December 31, 2023, respectively for the receipt of the Korean withholding tax. The Company also recorded foreign exchange loss of $1.4 million and $803,000 for thethree months ended June 30, 2024 and 2023, respectively, and $3.7 million and $1.8 million for thesix months ended June 30, 2024 and 2023, respectively, due to the fluctuation of the Korean Won to the U.S. Dollar and resulting remeasurement of this Won-denominated receivable. The Company will amend U.S. federal tax returns for the 2018 to 2022 years when the anticipated refund from KNTS is received to offset the additional tax liability. The Company has recorded a long-term liability of $15.7 million as of June 30, 2024, and December 31, 2023, for the estimated amounts due to the U.S. federal government based on the amendment of the Company's U.S. tax returns, indicating that lower withholding amounts were required.

The Company is not subject to examinations by the federal tax authority for the years prior to 2020. The Company's state and foreign tax returns are open for a period of generally three tofour years. The Company is under California tax audit for 2019 and 2020 years, which is in the information-collecting stage.

The above estimates may change in the future and upon settlement.

21. REVENUE RECOGNITION:

The Company recognizes revenue in accordance with ASC Topic 606, Revenue from Contracts with Customers (Topic 606). The standard establishes the principles that an entity shall apply to report useful information to users of financial statements about the nature, amount, timing, and uncertainty of revenue and cash flows from a contract with a customer.

For the three months ended June 30, 2024 and 2023, the Company recorded 98% and 97%, respectively, of its revenue from OLED related sales and 2% and 3%, respectively, from the providing of services through Adesis. For thesix months ended June 30, 2024 and 2023, the Company recorded 98% and 96%, respectively, of its revenue from OLED related sales and 2% and 4%, respectively, from the providing of services through Adesis.

Contract Balances

The following table provides information about assets and liabilities associated with our contracts from customers (in thousands):

Short-term and long-term unbilled receivables and contract assets are classified as other current assets and other assets, respectively, on the Consolidated Balance Sheets. Contract assets represent consideration related to the renewal of customer contracts which is recognized over the contract term based on material units sold. The deferred revenue balance as of June 30, 2024 will be recognized as materials are shipped to customers over the remaining contract periods. As of June 30, 2024, the Company had $50.8 million of backlog associated with committed purchase orders from its customers for phosphorescent emitter material. These orders are anticipated to be fulfilled within the next 90 days.

Significant changes in the assets and liabilities balances associated with the Company's contracts from customers for thesix months ended June 30, 2024 and 2023 are as follows (in thousands):

The cumulative catch-up adjustment recorded to revenue arising from changes in estimates of transaction price, net was an increase of $729,000 for thesix months ended June 30, 2024 as compared to an increase of $6.6 million for the six months ended June 30, 2023. For the six months ended June 30, 2023, the adjustment resulted from an increase in the average price per gram that was primarily due to the decrease in anticipated demand by several of the Company's customers over the remaining lives of their contracts, resulting from changes in global macroeconomic factors.

22. NET INCOME PER COMMON SHARE:

The Company computes earnings per share in accordance with ASC Topic 260, Earnings per Share, which requires earnings per share (EPS) for each class of stock to be calculated using the two-class method. The two-class method is an allocation of income between the holders of common stock and the Company's participating security holders. Under the two-class method, income for the reporting period is allocated between common shareholders and other security holders based on their respective participation rights in undistributed income. Unvested share-based payment awards that contain non-forfeitable rights to dividends or dividend equivalents are participating securities and, therefore, are included in computing earnings per share pursuant to the two-class method.

Basic net income per common share is computed by dividing net income allocated to common shareholders by the weighted-average number of shares of common stock outstanding for the period excluding unvested restricted stock units and performance units. Net income allocated to the holders of the Company's unvested restricted stock awards is calculated based on the shareholders proportionate share of weighted average shares of common stock outstanding on an if-converted basis.

For purposes of determining diluted net income per common share, basic net income per share is further adjusted to include the effect of potential dilutive common shares outstanding, including restricted stock units, performance units and the impact of shares to be issued under the Company's Employee Stock Purchase Plan.

The following table is a reconciliation of net income and the shares used in calculating basic and diluted net income per common share for thethree and six months ended June 30, 2024 and 2023 (in thousands, except share and per share data):

For the three months ended June 30, 2024 and 2023, the combined effects of unvested restricted stock awards, restricted stock units, performance unit awards and stock options of 17,540 and 75,251, respectively, were excluded from the calculation of diluted EPS as their impact would have been antidilutive. For the six months ended June 30, 2024 and 2023, the combined effects of unvested restricted stock awards, restricted stock units, performance unit awards and stock options of 44,535 and 31,578, respectively, were excluded from the calculation of diluted EPS as their impact would have been antidilutive.
