Credit Facility

The Company maintains a credit facility with a consortium of banks led by JPMorgan Chase Bank, N.A., as administrative agent, and the lenders, which was scheduled to mature on June 5, 2024 (the "Previous Credit Facility"). On May 8, 2023, the Company entered into an Amendment and Restatement Agreement, which provides an aggregate commitment of $750,000 of revolving loans available until May 8, 2028 (the “Amended and Restated Credit Facility”). The maturity date of the Amended and Restated Credit Facility will accelerate if within ninety-one days prior to the maturity of the Company’s convertible senior notes due 2025, the outstanding principal amount of such notes exceeds a defined liquidity measure as set forth in the Amended and Restated Credit Facility.

U.S. Dollar borrowings under the Amended and Restated Credit Facility bear interest at the Secured Overnight Financing Rate (“SOFR”) plus a credit spread and an interest margin. The Amended and Restated Credit Facility also allows for borrowings in euro, British sterling, and Japanese yen, subject to a $250,000 limit. Borrowings in foreign currency bear interest at a local reference rate plus an interest margin. The applicable interest margin is based on Vishay's total leverage ratio. Based on Vishay's current total leverage ratio, borrowings bear interest at SOFR plus 1.60%, including the applicable credit spread. Vishay also pays a commitment fee, also based on its total leverage ratio, on undrawn amounts. The undrawn commitment fee, based on Vishay's current total leverage ratio, is 0.25% per annum.

Similar to the Previous Credit Facility, the Amended and Restated Credit Facility requires the maintenance of financial covenant ratios. For compliance purposes, pursuant to the Amended and Restated Credit Facility, the leverage ratio is computed on a net basis, reducing the measure of outstanding debt by up to $250,000 of unrestricted cash. The Company must maintain a net leverage ratio of at least 3.25 to 1.00. Permitted investments and restricted payments are also subject to a pro forma net leverage ratio (2.75 to 1.00 and 2.50 to 1.00, respectively).

Other terms and conditions of the Amended and Restated Credit Facility are substantially similar to the Previous Credit Facility.

Convertible Debt Instruments

Convertible Senior Notes due 2030

In September 2023, the Company issued $750,000 aggregate principal amount of 2.25% convertible senior notes due 2030 (the “2030 Notes”) to qualified institutional buyers pursuant to an exemption from registration provided by Rule 144A under the Securities Act. The Company used the net proceeds from this offering to repurchase $370,242 principal amount of its outstanding 2.25% convertible senior notes due 2025 (the “2025 Notes”) (as further described below), to reduce the outstanding balance of its Amended and Restated Credit Facility, to enter into capped call transactions (as further described below), and for other general corporate purposes.

The 2030 Notes bear interest at a rate of 2.25% per year payable semi-annually in arrears on March 15 and September 15 of each year, beginning March 15, 2024. The 2030 Notes mature on September 15, 2030, unless earlier repurchased or converted.

The 2030 Notes are convertible into shares of Vishay common stock at an initial conversion rate of 33.1609 shares of common stock per $1 principal amount of the notes, subject to adjustment. This initial conversion price represents a premium of 20% to the closing price of Vishay's common stock on September 7, 2023, which was $25.13 per share. This represents an initial effective conversion price of approximately $30.16 per share. The conversion rate of the 2030 Notes is not adjusted for quarterly cash dividends equal to or less than $0.10 per share of common stock. Pursuant to the indenture governing the 2030 Notes, the Company is required to satisfy its conversion obligations by paying cash equal to the principal amount of notes and settle any additional value in cash and/or shares at its discretion. Vishay must provide additional shares upon conversion if there is a "fundamental change" in the business as defined in the indenture governing the notes.

The Company may not redeem the 2030 Notes prior to September 20, 2027. The Company may redeem for cash all or part of the 2030 Notes, at its option, on or after September 20, 2027, if the sale price of Vishay’s common stock has been at least 130% of the conversion price for a specified period at a redemption price equal to 100% of the principal amount of the notes to be redeemed, plus accrued and unpaid interest. If the Company elects to redeem fewer than all of the outstanding 2030 Notes, at least $100,000 aggregate principal amount of 2030 Notes must be outstanding and not subject to redemption.

Prior to March 15, 2030, the holders of the 2030 Notes may convert their notes only under the following conditions: (1) the sale price of Vishay common stock reaches 130% of the applicable conversion price for a specified period during any fiscal quarter commencing after the fiscal quarter ending on December 31, 2023; (2) the trading price of the notes falls below 98% of the product of the last reported sale price of Vishay’s common stock and the conversion rate for a specified period; (3) the Company calls any or all of the 2030 Notes for redemption; or (4) upon the occurrence of specified corporate transactions.

Capped Call Transactions

In September 2023, in connection with the pricing and initial purchasers’ exercise in full of their option to purchase additional 2030 Notes, the Company entered into separate base and additional privately negotiated capped call transactions with an affiliate of an initial purchaser and certain other financial institutions. The capped call will initially cover, subject to customary anti-dilution adjustments, the aggregate number of shares of the Company’s common stock that initially underlie the 2030 Notes. The Company used $94,200 of the net proceeds from the 2030 Notes to pay the cost of the capped call transactions. The cap price of the capped call will initially be $43.98 per share, which represents a premium of approximately 75% over the last reported sale price of the Company’s common stock on September 7, 2023, and is subject to certain adjustments under the terms of the capped call.

The capped call transactions are separate transactions entered into by the Company with each of the capped call counterparties, are not part of the terms of the 2030 Notes, and do not affect any holder’s rights under the 2030 Notes. Holders of the 2030 Notes do not have any rights with respect to the capped call. The capped call is classified within stockholders’ equity on the consolidated condensed balance sheet.

Convertible Senior Notes due 2025

The Company used $386,745 of the net proceeds from the offering of the 2030 Notes to repurchase $370,242 principal amount of its outstanding 2025 Notes. As a result, the Company recognized a loss on early extinguishment of the 2025 Notes of $18,874, including the write-off of a portion of unamortized debt issuance costs.

Prior to December 15, 2024, the holders of the convertible senior notes due 2025 may convert their notes only under the following circumstances: (1) the sale price of Vishay common stock reaches 130% of the conversion price for a specified period; (2) the trading price of the notes falls below 98% of the product of the sale price of Vishay's common stock and the conversion rate for a specified period; or (3) upon the occurrence of specified corporate transactions. The convertible senior notes due 2025 are not currently convertible.

Upon conversion of the convertible senior notes due 2025, Vishay will satisfy its conversion obligations by paying $1 cash per $1 principal amount of converted notes and settle any additional amounts due in common stock.

The quarterly cash dividend program of the Company results in adjustments to the conversion rate and effective conversion price for the convertible senior notes due 2025 effective as of the ex-dividend date of each cash dividend. The conversion rate and effective conversion price for the convertible senior notes due 2025 is adjusted for quarterly cash dividends to the extent such dividends exceed $0.085 per share of common stock.

The following table summarizes some key facts and terms regarding the outstanding convertible senior notes as of September 30, 2023:

	2025 Notes			2030 Notes
Issuance date	June 12, 2018			September 12, 2023
Maturity date	June 15, 2025			September 15, 2030
Principal amount as of September 30, 2023	$	95,102		$	750,000
Cash coupon rate (per annum)		2.25	%		2.25	%
Conversion rate (per $1 principal amount)		32.1062			33.1609
Effective conversion price (per share)	$	31.15		$	30.16
130% of the current effective conversion price (per share)	$	40.50		$	39.21

Acquisition and Divestiture Activities	9 Months Ended
Acquisition and Divestiture Activities	Sep. 30, 2023
Acquisition and Divestiture Activities [Abstract]
Acquisition and Divestiture Activities	Note 2 – Acquisition Activities As part of its growth strategy, the Company seeks to expand through targeted acquisitions of other manufacturers of electronic components. These acquisition targets include businesses that have established positions in major markets, reputations for product quality and reliability, and product lines with which the Company has substantial marketing and technical expertise. It also includes certain businesses that possess technologies which the Company expects to further develop and commercialize. MaxPower Semiconductor, Inc. On October 28, 2022, the Company acquired all of the outstanding equity interests of MaxPower Semiconductor, Inc. ("MaxPower"), a San Jose, California-based fabless power semiconductor provider dedicated to delivering innovative and cost-effective technologies that optimize power management solutions. The acquisition of MaxPower will enhance the Company's current and future silicon carbide ("SiC") offerings for fast-growing markets such as electric vehicles. The Company paid cash of $50,000, net of cash acquired, at closing. Related to the transaction, Vishay may also be required to make certain contingent payments of up to $57,500, which would be payable upon the achievement of certain technology milestones, upon favorable resolution of certain technology licensing matters with a third party, and upon the disposition of MaxPower's investment in an equity affiliate. The purchase price for U.S. GAAP purposes includes the fair value, as of the acquisition date, of certain future contingent payments to non-employee equity holders of MaxPower. The estimated fair value of this contingent consideration as of the acquisition date was $6,851. The contingent consideration liability is included in other accrued expenses and other liabilities in the accompanying balance sheet and is remeasured each reporting period, with changes reported as selling, general, and administrative expenses on the consolidated condensed statement of operations. See Note 13 for further discussion on the fair value measurement. Based on an estimate of their fair values, the Company allocated $18,600 of the purchase price to definite-lived intangible assets. After allocating the purchase price to the assets acquired and liabilities assumed based on an estimation of their fair values at the date of acquisition, the Company recorded goodwill of $34,246 related to this acquisition. The goodwill related to this acquisition is included in the MOSFETs reporting unit for goodwill impairment testing. The results and operations of this acquisition have been included in the MOSFETs segment since October 28, 2022. Centerline Technologies, LLC On June 30, 2023, the Company acquired substantially all of the assets of Centerline Technologies, LLC ("Centerline"), a Massachusetts-based, privately held manufacturer of ceramic components used in many custom parts manufactured by certain of Vishay's Resistors businesses, for $5,003. Based on an estimate of fair values, the Company allocated $1,500 of the purchase price to definite-lived intangible assets. After allocating the purchase price to the assets acquired and liabilities assumed based on an estimation of their fair values at the date of acquisition, the Company recorded goodwill of $2,213 related to this acquisition. The acquired business will be vertically integrated into the Company's Resistors segment, and the goodwill related to this acquisition is included in the Resistors reporting unit for goodwill impairment testing. The results and operations of this acquisition have been included in the Resistors segment since June 30, 2023.

Income Taxes	9 Months Ended
Income Taxes	Sep. 30, 2023
Income Taxes [Abstract]
Income Taxes	Note 4 – Income Taxes The provision for income taxes consists of provisions for federal, state, and foreign income taxes. The effective tax rates for the periods ended September 30, 2023 and October 1, 2022 reflect the Company’s expected tax rate on reported income before income tax and tax adjustments. The Company operates in a global environment with significant operations in various jurisdictions outside the United States. Accordingly, the consolidated income tax rate is a composite rate reflecting the Company’s earnings and the applicable tax rates in the various jurisdictions where the Company operates. During the nine fiscal months ended September 30, 2023, the liabilities for unrecognized tax benefits decreased by $4,483 on a net basis, primarily due to decreases for settlements, partially offset by increases for current accruals and interest.

- Definition

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

Note 10 – Stock-Based Compensation

2023 Long-Term Incentive Plan

The Company implemented the Vishay Intertechnology, Inc. 2023 Long-Term Incentive Plan (the "2023 Plan") after receiving stockholder approval at its 2023 Annual Meeting of Stockholders on May 23, 2023. The 2023 Plan allows the Company to grant up to 6,000,000 shares (subject to certain adjustments described in the 2023 Plan) of stock options, stock appreciation rights, restricted stock, restricted stock units, other stock-based awards, phantom stock units, and other cash-based awards to employees, directors, consultants, and other service providers of the Company and its affiliates. Such instruments are available for grant until March 24, 2033. The Company has granted approximately 740,000 time-vested restricted stock units to employees pursuant to the 2023 Plan.

2007 Stock Incentive Program

Under the Company's 2007 Stock Incentive Program (the "2007 Program"), as amended and restated, certain executive officers and board members of the Company were granted restricted stock units. No further awards will be granted pursuant to the 2007 Program. Pursuant to the terms of the 2023 Plan, any shares of common stock that are subject to outstanding awards granted pursuant to the 2007 Program that subsequently cease to be subject to such awards as a result of the termination, expiration, cancellation, or forfeiture of such awards and any shares of common stock withheld in settlement of tax withholding obligations associated with outstanding awards granted pursuant to the 2007 Program may become available for issuance under the 2023 Plan. A total of 1,294,546 shares of common stock were subject to awards granted pursuant to the 2007 Program as of May 23, 2023.

The following table summarizes stock-based compensation expense recognized:

* Employees in certain countries are granted equity-linked awards that will be settled in cash and are accounted for as liability awards. The liability awards are not material. The number of RSUs granted excludes these awards.

** The number of RSUs vested includes shares that the Company withheld on behalf of employees to satisfy the statutory tax withholding requirements.

In addition to RSUs that vest based upon satisfaction of service or performance conditions, in 2023, the Company granted RSUs that vest based upon achievement of market conditions to certain executive officers. For RSUs with market conditions, the Company estimates the grant date fair value using a Monte Carlo valuation model and recognizes the expense for the awards over the period in which the condition is assessed regardless of whether the market condition is ultimately achieved. The number of performance-based RSUs that are scheduled to vest increases ratably based on the achievement of defined performance and market criteria between the established target and maximum levels. RSUs with performance-based and market-based vesting criteria are expected to vest as follows (number of RSUs in thousands):

If the average market price of Vishay common stock is less than the effective conversion prices of the convertible senior notes due 2025 and due 2030, respectively, no shares are included in the diluted earnings per share computation for the convertible senior notes due 2025 and due 2030. Upon Vishay exercising its existing right to legally amend the indenture governing the convertible senior notes due 2025, Vishay will satisfy its conversion obligations by paying $1 cash per $1 principal amount of converted notes and settle any additional amounts due in common stock. Pursuant to the indenture governing the convertible senior notes due 2030, Vishay will satisfy its conversion obligations by paying $1 cash per $1 principal amount of converted notes and settle any additional amounts due in cash and/or common stock. Accordingly, the convertible senior notes due 2025 and due 2030 are not anti-dilutive when the average market price of Vishay common stock is less than the respective effective conversion prices of the convertible senior notes due 2025 and due 2030.

In connection with the issuance of the convertible senior notes due 2030, the Company entered into capped call transactions (see Note 5), which were not included in the calculation of diluted earnings per share as their effect would have been anti-dilutive. The capped calls are intended to reduce the potential dilution to the Company's common stock in the event that at the time of conversion of the convertible senior notes due 2030 the Company's common stock price exceeds the conversion price of the convertible senior notes due 2030.

Fair Value Measurements

Note 13 – Fair Value Measurements

The following table provides the financial assets and liabilities carried at fair value measured on a recurring basis:

	Total Fair Value		Level 1		Level 2		Level 3

There have been no changes in the classification of any financial instruments within the fair value hierarchy in the periods presented.

The Company maintains non-qualified trusts, referred to as “rabbi” trusts, to fund payments under deferred compensation and non-qualified pension plans. Rabbi trust assets consist primarily of marketable securities, classified as available-for-sale and company-owned life insurance assets. The marketable securities held in the rabbi trusts are valued using quoted market prices on the last business day of the period. The company-owned life insurance assets are valued in consultation with the Company’s insurance brokers using the value of underlying assets of the insurance contracts. The fair value measurement of the marketable securities held in the rabbi trust is considered a Level 1 measurement and the measurement of the company-owned life insurance assets is considered a Level 2 measurement within the fair value hierarchy.

The Company holds investments in debt securities that are intended to fund a portion of its pension and other postretirement benefit obligations outside of the United States. The investments are valued based on quoted market prices on the last business day of the period. The fair value measurement of the investments is considered a Level 1 measurement within the fair value hierarchy.

From time to time, the Company purchases precious metals bullion in excess of its immediate manufacturing needs to mitigate the risk of supply shortages or volatile price fluctuations. The metals are valued based on quoted market prices on the last business day of the period. The fair value measurement of the metals is considered a Level 1 measurement within the fair value hierarchy. The inventory of precious metals bullion in excess of its immediate manufacturing needs was not material at September 30, 2023.

The Company may be required to make certain contingent payments to non-employee equity holders of MaxPower pursuant to the acquisition agreement, which would be payable upon the achievement of certain technology milestones, upon favorable resolution of certain technology licensing matters with a third party, and upon the disposition of MaxPower's investment in an equity affiliate. The fair value of these contingent consideration payments is determined by estimating the net present value of the expected cash flows based on the probability of expected payments. The fair value measurement of the contingent consideration is considered a Level 3 measurement within the fair value hierarchy.

The fair value of the long-term debt, excluding the derivative liabilities and deferred financing costs, at September 30, 2023 and December 31, 2022 is approximately $831,400 and $491,100, respectively, compared to its carrying value, excluding the deferred financing costs, of $845,102 and $507,344, respectively. The Company estimates the fair value of its long-term debt using a combination of quoted market prices for similar financing arrangements and expected future payments discounted at risk-adjusted rates, which are considered Level 2 inputs.

At September 30, 2023 and December 31, 2022, the Company’s short-term investments were comprised of time deposits with financial institutions that have maturities that exceed 90 days from the date of acquisition; however they all mature within one year from the respective balance sheet dates. The Company's short-term investments are accounted for as held-to-maturity debt instruments, at amortized cost, which approximates their fair value. The investments are funded with excess cash not expected to be needed for operations prior to maturity; therefore, the Company believes it has the intent and ability to hold the short-term investments until maturity. At each reporting date, the Company performs an evaluation to determine if any unrealized losses are other-than-temporary. No other-than-temporary impairments have been recognized on these securities, and there are no unrecognized holding gains or losses for these securities during the periods presented. There have been no transfers to or from the held-to-maturity classification. All decreases in the account balance are due to returns of principal at the securities’ maturity dates. Interest on the securities is recognized as interest income when earned.

At September 30, 2023 and December 31, 2022, the Company’s cash and cash equivalents were comprised of demand deposits, time deposits with maturities of three months or less when purchased, and money market funds. The Company estimates the fair value of its cash, cash equivalents, and short-term investments using Level 2 inputs. Based on the current interest rates for similar investments with comparable credit risk and time to maturity, the fair value of the Company's cash, cash equivalents, and held-to-maturity short-term investments approximate the carrying amounts reported in the consolidated condensed balance sheets.

The Company’s financial instruments also include accounts receivable and accounts payable. The carrying amounts for these financial instruments reported in the consolidated condensed balance sheets approximate their fair values.
