NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

(in thousands, except per share data)

NOTE 1:       GENERAL

a. SolarEdge Technologies Inc. (the “Company”) and its subsidiaries design, develop, and sell an intelligent inverter solution designed to maximize power generation at the individual photovoltaic (“PV”) module level while lowering the cost of energy produced by the solar PV system and providing comprehensive and advanced safety features. The Company’s products consist mainly of (i) power optimizers designed to maximize energy throughput from each and every module through constant tracking of Maximum Power Point individually per module, (ii) inverters which invert direct current (DC) from the PV module to alternating current (AC) including the Company’s Energy Hub inverter which supports, among other things, connection to a DC-coupled battery for full or partial home backup, and optional connection to the Company's smart EV charger, (iii) a remote cloud-based monitoring platform, that collects and processes information from the power optimizers and inverters to enable customers and system owners, to monitor and manage the solar PV system (iv) a residential storage and backup solution which includes a company designed and manufactured lithium-ion DC-coupled battery that is used to increase energy independence and maximize self-consumption for homeowners including a battery, and (v) additional smart energy management solutions.

The Company and its subsidiaries sell products worldwide through large distributors, electrical equipment wholesalers, as well as directly to large solar installers and engineering, procurement, and construction firms.

b. The Company has expanded its activity to other areas of smart energy technology organically and through acquisitions. The Company now offers a variety of energy solutions, which include lithium-ion cells, batteries, and energy storage systems (“Energy Storage”), full powertrain kits for electric vehicles, or EVs (“e-Mobility”), as well as automated machines for industrial use (“Automation Machines”).

On April 6, 2023, the Company completed the acquisition of all outstanding shares of Hark Systems Ltd. ("Hark"), a UK-based energy IoT company for the commercial and industrial ("C&I") sector, which operates under the newly established consulting segment (see note 2).

c. Basis of Presentation:

The unaudited condensed consolidated financial statements and accompanying notes have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”). In management’s opinion, the unaudited condensed consolidated financial statements reflect all adjustments of a normal recurring nature that are necessary for a fair presentation of the results for the interim periods presented. The Company’s interim period results do not necessarily indicate the results that may be expected for any other interim period or for the full fiscal year.

The significant accounting policies applied in the annual consolidated financial statements of the Company as of December 31, 2022, contained in the Company’s Annual Report on Form 10-K filed with the SEC on February 22, 2023, have been applied consistently in these unaudited interim condensed consolidated financial statements. Certain prior year amounts have been reclassified to conform to current year presentation.

d. Use of estimates:

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, costs and expenses and related disclosures in the accompanying notes. Actual results and outcomes may differ from management’s estimates and assumptions due to risks and uncertainties.

e. Concentrations of supply risks:

The Company depends on two contract manufacturers and several limited or single source component suppliers. Reliance on these vendors makes the Company vulnerable to possible capacity constraints and reduced control over component availability, delivery schedules, manufacturing yields, and costs.

As of September 30, 2023, and December 31, 2022, two contract manufacturers collectively accounted for 40.9% and 34.3% of the Company’s total trade payables, net, respectively.

In the second quarter of 2022, the Company announced the opening of “Sella 2”, a two gigawatt-hour (GWh) Li-Ion battery cell manufacturing facility located in South Korea. Sella 2 began producing and shipping cells at the end of 2022 and is expected to reach full manufacturing capacity in early 2024. Sella 2 is the Company's second owned manufacturing facility following the establishment of Sella 1 in 2020. Sella 1 is the Company's manufacturing facility in the North of Israel that produces power optimizers and inverters for the Company's solar activities.

f. New accounting standards updates:

From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board ("FASB") or other standard setting bodies are adopted by the Company as of the specified effective date. The Company believes that the impact of recently issued or newly effective standards were not applicable to the Company, did not have a material impact on the condensed consolidated financial statements or are not expected to have a material impact on the condensed consolidated financial statements.

NOTE 2:       BUSINESS COMBINATIONS

On April 6, 2023, the Company completed the acquisition of all outstanding shares of Hark Systems Ltd. ("Hark"), a UK-based energy IoT company for the commercial and industrial ("C&I") sector for approximately $18,346 in cash. Hark's platform is expected to enable the Company to offer its commercial and industrial customers expanded capabilities in energy management and connectivity, including identification of potential energy savings, detection of anomalies in assets’ energy consumption, and optimization of energy usage and carbon emissions through load orchestration and storage control.

Pursuant to ASC 805, "Business Combination", the Company accounted for the Hark acquisition as a business combination using the acquisition method of accounting. Identifiable assets and liabilities of Hark, including identifiable intangible assets, were recorded based on their estimated fair values as of the date of the closing of the acquisition. The excess of the purchase price over the fair value of the net assets acquired was recorded as goodwill. The Company recorded preliminary estimates for the fair value of assets acquired and liabilities assumed as of the acquisition date. Such preliminary valuation required estimates and assumptions including, but not limited to, estimating future cash flows and direct costs in addition to developing the appropriate discount rates and current market profit margins. The Company’s management believes the fair values recognized for the assets acquired and the liabilities assumed were based on reasonable estimates and assumptions.

The following table summarizes the preliminary fair values estimation of assets acquired and liabilities assumed as of the date of the acquisition:

	Amount			Weighted Average Useful Life (In years)
Cash	$	448
Net liabilities assumed		(1,837	)
Identified intangible assets:
Current technology		6,576			5
Customer relationships		283			1
Trade name		610			5
Goodwill		12,266

Acquisition costs were immaterial and are included in general and administrative expenses in the consolidated statements of income.

Goodwill generated from this acquisition was primarily attributable to the assembled workforce and expected post-acquisition synergies from combining Hark platform with the Company's product offering to its commercial and industrial customers. All of the Goodwill was assigned to the new Consulting segment (see Note 21). Goodwill was not deductible for tax purposes. The fair values of technology, customer relationships and trade name were derived by applying the multi-period excess earnings method, with-and-without method, and the relief-from-royalty method, respectively, all of which are under the income approach whose underlying inputs are considered Level 3. The fair values assigned to assets acquired and liabilities assumed were based on management's estimates and assumptions.

The results of Hark have been included in the Company's consolidated statements of income (loss) since the acquisition date and are not material. Pro forma financial information has not been presented because the impact of the acquisition was not material to the Company's statement of income.

NOTE 9:       DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

During the nine months ended September 30, 2023, the Company instituted a foreign currency cash flow hedging program to reduce the risk of a forecasted increase in the value of foreign currency cash flows, resulting from payment of salaries in Israeli currency, the New Israeli Shekels (“NIS”). The Company hedges portions of the anticipated payroll denominated in NIS for a period of one to nine months with hedging contracts. These hedging contracts are designated as cash flow hedges, as defined by ASC 815 and are all effective hedges.

As of September 30, 2023, the Company entered into forward contracts and put and call options to sell U.S. dollars (“USD”) for NIS in the amount of approximately NIS 38 million and NIS 622 million, respectively.

In addition to the above-mentioned cash flow hedge transactions, the Company occasionally enters into derivative instrument arrangements to hedge the Company’s exposure to currencies other than the USD. These derivative instruments are not designated as cash flow hedges, as defined by ASC 815, and therefore all gains and losses, resulting from fair value remeasurement, were recorded immediately in the statement of income, under "Financial income (expense), net".

As of September 30, 2023, the Company entered into put and call option contracts to sell Euro ("EUR") for USD in the amount of EUR 120 million.

The Company classifies cash flows related to its hedging as operating activities in its condensed consolidated statement of cash flows.

The fair values of outstanding derivative instruments were as follows:

	Balance sheet location	September 30, 2023			December 31, 2022
Derivative assets of options and forward contracts:
Designated cash flow hedges	Prepaid expenses and other current assets	$	87		$	-

NOTE 14:      CONVERTIBLE SENIOR NOTES

On September 25, 2020, the Company sold $632,500 aggregate principal amount of its 0.00% convertible senior notes due 2025 (the “Notes”). The Notes were sold pursuant to an indenture, dated September 25, 2020 (the “Indenture”), between the Company and U.S. Bank National Association, as trustee. The Notes do not bear regular interest and mature on September 15, 2025, unless earlier repurchased or converted in accordance with their terms. The Notes are general senior unsecured obligations of the Company. Holders may convert their Notes prior to the close of business on the business day immediately preceding June 15, 2025 in multiples of $1,000 principal amount, only under the following circumstances: (1) during any calendar quarter commencing after the calendar quarter ending on December 31, 2020 (and only during such calendar quarter), if the last reported sale price of the common stock for at least 20 trading days (whether or not consecutive) during the period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day; (2) during the five-business-day period after any five consecutive trading day period in which the trading price per $1,000 principal amount of the Notes for each trading day of that five consecutive trading day period was less than 98% of the product of the last reported sale price of the common stock and the conversion rate on each such trading day; or (3) upon the occurrence of specified corporate events as described in the Indenture. In addition, holders may convert their Notes, in multiples of $1,000 principal amount, at their option at any time beginning on or after June 15, 2025, and prior to the close of business on the second scheduled trading day immediately preceding the stated maturity date of the Notes, without regard to the foregoing circumstances. The initial conversion rate for the Notes was 3.5997 shares of common stock per $1,000 principal amount of Notes, which is equivalent to an initial conversion price of approximately $277.80 per share of common stock, subject to adjustment upon the occurrence of certain specified events as set forth in the Indenture.

Upon conversion, the Company may choose to pay or deliver, as the case may be, cash, shares of common stock, or a combination of cash and shares of common stock.

In addition, upon the occurrence of a fundamental change (as defined in the Indenture), holders of the Notes may require the Company to repurchase all or a portion of their Notes, in multiples of $1,000 principal amount, at a repurchase price of 100% of the principal amount of the Notes, plus any accrued and unpaid special interest to, but excluding the fundamental change repurchase date. If certain fundamental changes referred to as make-whole fundamental changes occur, the conversion rate for the Notes may be increased.

The Convertible Senior Notes consisted of the following as of September 30, 2023 and December 31, 2022:

	September 30,  2023			December 31,  2022
Liability:
Principal	$	632,500		$	632,500
Unamortized issuance costs		(5,853	)		(8,049	)
Net carrying amount	$	626,647		$	624,451

For the three months ended September 30, 2023 and 2022 the Company recorded amortized debt issuance costs related to the Notes in the amount of $733 and $730, respectively.

For the nine months ended September 30, 2023 and 2022 the Company recorded amortized debt issuance costs related to the Notes in the amount of $2,196 and $2,186, respectively.

As of September 30, 2023, the unamortized issuance costs of the Notes will be amortized over the remaining term of approximately 2 years.

The annual effective interest rate of the Notes is 0.47%.

As of September 30, 2023, the estimated fair value of the Notes, which the Company has classified as Level 2 financial instruments, is $578,048. The estimated fair value was determined based on the quoted bid price of the Notes in an over-the-counter market on the last trading day of the reporting period.

As of September 30, 2023, the if-converted value of the Notes did not exceed the principal amount.

a. Common stock rights:

Common stock confers upon its holders the right to receive notice of, and to participate in, all general meetings of the Company, where each share of common stock shall have one vote for all purposes, to share equally, on a per share basis, in bonuses, profits, or distributions out of fund legally available therefor, and to participate in the distribution of the surplus assets of the Company in the event of liquidation of the Company.

b. Secondary public offering:

On March 17, 2022, the Company offered and sold 2,300,000 shares of the Company’s common stock, at a public offering price of $295.00 per share. The shares of Common Stock were issued and sold in a registered offering pursuant to the underwriting agreement dated March 17, 2022, among the Company, Goldman Sachs & Co. LLC, J.P. Morgan Securities LLC, and Morgan Stanley & Co. LLC (the “Underwriting Agreement”). All of the offered shares were issued at closing, including 300,000 shares of Common Stock that were issued and sold pursuant to the underwriters’ option to purchase additional shares under the Underwriting Agreement, which was exercised in full on March 18, 2022.

The net proceeds to the Company were $650,526 after deducting underwriters' discounts of $27,140 and commissions of $834.

c. Equity Incentive Plans:

The Company’s 2007 Global Incentive Plan (the “2007 Plan”) was adopted by the board of directors on August 30, 2007. The 2007 Plan terminated upon the Company’s IPO on March 31, 2015 and no further awards may be granted thereunder. All outstanding awards will continue to be governed by their existing terms and 379,358 available options for future grants were transferred to the Company’s 2015 Global Incentive Plan (the “2015 Plan”) and are reserved for future issuances under the 2015 plan. The 2015 Plan became effective upon the consummation of the IPO. The 2015 Plan provides for the grant of options, restricted stock units ("RSU"), performance stock units ("PSU"), and other share-based awards to directors, employees, officers, and non-employees of the Company and its subsidiaries. As of September 30, 2023, a total of 20,853,755 shares of common stock were reserved for issuance pursuant to stock awards under the 2015 Plan (the “Share Reserve”), an aggregate of 11,845,915 shares are still available for future grants.

The Share Reserve will automatically increase on January 1^st of each year during the term of the 2015 Plan, commencing on January 1^st of the year following the year in which the 2015 Plan becomes effective, in an amount equal to 5% of the total number of shares of capital stock outstanding on December 31^st of the preceding calendar year; provided, however, that the Company’s board of directors may determine that there will not be a January 1^st increase in the Share Reserve in a given year or that the increase will be less than 5% of the shares of capital stock outstanding on the preceding December 31^st.

The Company granted under its 2015 Plan, PSU awards to certain employees and officers which vest upon the achievement of certain performance or market conditions subject to their continued employment with the Company.

The market condition for the PSUs is based on the Company’s total shareholder return ("TSR") compared to the TSR of companies listed in the S&P 500 index over a one to three year performance period. The Company uses a Monte-Carlo simulation to determine the grant date fair value for these awards, which takes into consideration the market price of a share of the Company’s common stock on the date of grant less the present value of dividends expected during the requisite service period, as well as the possible outcomes pertaining to the TSR market condition. The Company recognizes such compensation expenses on an accelerated vesting method.

The aggregate maximum number of shares of common stock that may be issued on the exercise of incentive stock options is 10,000,000. As of September 30, 2023, an aggregate of 8,617,974 options are still available for future grants under the 2015 Plan.

d. Employee Stock Purchase Plan ("ESPP"):

The Company adopted an ESPP effective upon the consummation of the IPO. As of September 30, 2023, a total of 4,150,380 shares were reserved for issuance under this plan. The number of shares of common stock reserved for issuance under the ESPP will increase automatically on January 1^st of each year, for ten years, by the lesser of 1% of the total number of shares of the Company’s common stock outstanding on December 31st of the preceding calendar year or 487,643 shares. However, the Company’s board of directors may reduce the amount of the increase in any particular year at their discretion, including a reduction to zero.

The ESPP is implemented through an offering every six months. According to the ESPP, eligible employees may use up to 15% of their salaries to purchase common stock up to an aggregate limit of $15 per participant for every six months plan. The price of an ordinary share purchased under the ESPP is equal to 85% of the lower of the fair market value of the ordinary share on the subscription date of each offering period or on the purchase date.

As of September 30, 2023, 780,370 shares of common stock have been purchased under the ESPP.

As of September 30, 2023, 3,370,010 shares of common stock were available for future issuance under the ESPP.

In accordance with ASC No. 718, the ESPP is compensatory and, as such, results in recognition of compensation cost.

NOTE 16:     COMMITMENTS AND CONTINGENT LIABILITIES

a. Guarantees:

As of September 30, 2023, contingent liabilities exist regarding guarantees in the amounts of $5,804, and $1,821 in respect of office rent lease agreements and other transactions, respectively.

b. Contractual purchase obligations:

The Company has contractual obligations to purchase goods and raw materials. These contractual purchase obligations relate to inventories and other purchase orders, which cannot be canceled without penalty. In addition, the Company acquires raw materials or other goods and services, including product components, by issuing authorizations to its suppliers to purchase materials based on its projected demand and manufacturing needs.

As of September 30, 2023, the Company had non-cancellable purchase obligations totaling approximately $1,116,593, out of which the Company recorded a provision for loss in the amount of $13,463.

As of September 30, 2023, the Company had contractual obligations for capital expenditures totaling approximately $120,572. These commitments reflect purchases of automated assembly lines and other machinery related to the Company’s general manufacturing process and mainly to its new manufacturing site in the U.S.

c. Legal claims:

From time to time, the Company may be involved in various claims and legal proceedings. The Company reviews the status of each matter and assesses its potential financial exposure. If the potential loss from any claim or legal proceeding is considered probable and the amount can be reasonably estimated, the Company accrues a liability for the estimated loss. These accruals are reviewed at least quarterly and adjusted to reflect the impact of negotiations, settlements, rulings, advice of legal counsel, and other information and events pertaining to a particular matter.

In September 2018, the Company’s German subsidiary, SolarEdge Technologies GmbH, received a complaint filed by competitor SMA Solar Technology AG (“SMA”). The complaint, filed in the District Court Düsseldorf, Germany, alleged that SolarEdge's 12.5kW - 27.6kW inverters infringed on two of the plaintiff’s patents. SMA asserted a value in dispute of EUR 5.5 million (approximately $5,830) for both patents. The Company challenged the validity of both patents and the first patent was invalidated and SMA’s appeal on the matter was denied in January 2023. In August 2021, the German Patent Court rendered SMA's second patent invalid, and this invalidity has been appealed by SMA. In May 2023 the Federal Supreme Court as final instance in the nullity proceedings revoked the second patent, and SMA withdrew its infringement complaint.

On July 28, 2022, the Company and its subsidiary SolarEdge Technologies Ltd were served with complaints filed by Ampt LLC ("Ampt") in the International Trade Commission (the “Commission”) pursuant to Section 337 of the Tariff Act of 1930, as amended, and related lawsuits in the District Court for the District of Delaware alleging patent infringement against the Company. On May 9, 2023, Ampt and the Company entered into a settlement agreement pursuant to which the parties agreed to dismiss all proceedings related to the complaints, and the parties have granted each other 10-year cross-licenses for certain intellectual property.

As of September 30, 2023, an immaterial amount for legal claims was recorded in accrued expenses and other current liabilities.

NOTE 19:      INCOME TAXES

The effective tax rate for the three months ended September 30, 2023, and 2022 was (143.6)% and 58.0%, respectively.

The change in effective tax rate in the three months ended September 30, 2023 compared to the corresponding period in 2022 is mainly due to the IRC Section 174 R&D capitalization, and other expenses not recognized for GILTI purposes, which did not decrease in line with the decrease in our taxable income, as well as unfavorable impact of losses in foreign subsidiaries where we do not anticipate a future tax benefit.

The effective tax rate for the nine months ended September 30, 2023 and 2022 was 33.6% and 42.1%, respectively.

The lower tax rate in the nine months ended September 30, 2023 compared to the corresponding period in 2022 is mainly due to the fact that the Company's income before tax, most of which is subject to tax rates lower than the US statutory rate, increased. Conversely, the IRC Section 174 R&D capitalization, and other expenses not recognized for GILTI purposes, did not increase in the same proportion.

As of September 30, 2023, and December 31, 2022, unrecognized tax benefits were $3,155 and $2,756, respectively. If recognized, such benefits would favorably affect the Company’s effective tax rate.

The Company accrues interest and penalties related to unrecognized tax benefits in its provision for income taxes. The total amount of penalties and interest were immaterial as of September 30, 2023, and December 31, 2022.

In August 2022, the U.S. government enacted the Inflation Reduction Act of 2022 (the “IRA”), which includes several incentives intended to promote clean energy, battery and energy storage, electrical vehicles, and other solar products, and is expected to impact our business and operations. As part of such incentives the IRA, will among other things, extend the investment tax credit (“ITC”) through 2034 and is therefore expected to increase the demand for solar products. The IRA is expected to further incentivize residential and commercial solar customers and developers due to the inclusion of a tax credit for qualifying energy projects of up to 30%. Since these regulations are new and their implementation is still pending administrative guidance from the Internal Revenue Service and U.S. Treasury Department, the Company will be examining the benefits that may be available to it, such as the availability of tax credits for domestic manufacturers, in the coming months. During the third quarter, the Company began manufacturing inverters in the U.S..

NOTE 21:      SEGMENT INFORMATION

Following the discontinuation of Critical Power in June 2022, the Company operates in five different operating segments: Solar, Energy Storage, e-Mobility, Automation Machines, and the newly formed Consulting segment.

The Company’s Chief Executive Officer, who is the chief operating decision maker (“CODM”), makes resource allocation decisions and assesses performance based on financial information presented on a consolidated basis, accompanied by disaggregated information about revenues and contributed profit by the operating segments.

The Company does not allocate to its operating segments revenue recognized due to advance payments received for performance obligations that extend for a period greater than one year, related to ASC 606, “Revenue from Contracts with Customers”.

Segment profit is comprised of gross profit for the segment less operating expenses that do not include amortization of purchased intangible assets, impairments of goodwill and intangible assets, stock based compensation expenses, and certain other items.

The Company manages its assets on a group basis, not by segments, as many of its assets are shared or co-mingled. The Company’s CODM does not regularly review asset information by segments and, therefore, the Company does not report asset information by segment.

The Company identified one operating segment as reportable – the Solar segment. The other operating segments are insignificant individually and therefore their results are presented together under “All other”.

The Solar segment includes the design, development, manufacturing, and sales of an intelligent inverter solution designed to maximize power generation at the individual PV module level and a residential storage solution, compatible with the Company’s Energy Hub inverter, intended to store and supply power for back-up and to maximize self-consumption. The Solar segment solution consists mainly of the Company’s power optimizers, inverters, batteries, and cloud‑based monitoring platform.

The “All other” category includes the design, development, manufacturing, and sales of energy storage products, e-Mobility products, automated machines, and consulting services.

The following tables present information on reportable segments profit (loss) for the period presented:

NOTE 22:      SUBSEQUENT EVENTS

1. On November 1, 2023, the Company announced the approval by the Board of Directors of a share repurchase program which authorizes the repurchase of up to $300 million of the Company’s common stock. Under the share repurchase program, repurchases can be made using a variety of methods, which may include open market purchases, block trades, privately negotiated transactions, accelerated share repurchase programs and/or a non-discretionary trading plan or other means, including through 10b5-1 trading plans, all in compliance with the rules of the SEC and other applicable legal requirements. The timing, manner, price and amount of any common share repurchases under the share repurchase program are determined by the Company in its discretion and depend on a variety of factors, including legal requirements, price and economic and market conditions. The program does not obligate the Company to acquire any amount of common stock, it may be suspended, extended, modified, discontinued or terminated at any time at the Company’s discretion without prior notice, and will expire on December 31, 2024.

2. In October 2023, the Company decided to discontinue its light commercial e-Mobility ("LCV") activity related to the supply of products to its sole customer.

3. On November 3, 2023, Daphne Shen, a purported stockholder of the Company, filed a proposed class action complaint for violation of federal securities laws, individually and putatively on behalf of all others similarly situated, in the U.S District Court of the Southern District of New York against the Company, the Company’s CEO and the Company’s CFO. The complaint alleges that the Company violated various securities laws and seeks class certification, damages, interest, attorneys’ fees, and other relief. Due to the early stage of this proceeding, we cannot reasonably estimate the potential range of loss, if any. The Company disputes the allegations of wrongdoing and intends to vigorously defend against them.

Overview

We are a leading provider of an optimized inverter solution that has changed the way power is harvested and managed in a solar photovoltaic, known as PV systems. Our direct current or DC optimized inverter system maximizes power generation while lowering the cost of energy produced by the solar PV system, for improved return on investment, or ROI. Additional benefits of the DC optimized inverter system include comprehensive and advanced safety features, improved design flexibility, efficient integration (DC coupled) with SolarEdge storage solutions, and improved operating and maintenance, or O&M with remote monitoring at the module level. The SolarEdge Energy Hub inverter supports, among other things, connection to a DC-coupled battery for full or partial home backup, and optional connection to the SolarEdge smart EV charger. The typical SolarEdge optimized inverter system consists of power optimizers, inverters, a communication device that enables access to a cloud-based monitoring platform and in many cases, a battery and additional smart energy management solutions. Our solutions address a broad range of solar market segments, from residential to commercial and small utility-scale solar installations.

Since introducing the optimized inverter solution in 2010, SolarEdge has expanded its activity to other areas of smart energy technology, both through organic growth and through acquisitions. SolarEdge now offers energy solutions which also include energy storage systems or ESS, home backup systems, electric vehicle, or EV, components and charging capabilities, home energy management, grid services and virtual power plants, or VPPs, and lithium-ion batteries.

In the third quarter of 2020, we began commercial shipments from our manufacturing facility in the North of Israel, “Sella 1”. The proximity of Sella 1 to our R&D team and labs enables us to accelerate new product development cycles, as well as define equipment and manufacturing processes of newly developed products which can then be adopted by our contract manufacturers world-wide. In 2023, we expanded the manufacturing capacity of Sella 1 to add an additional inverter line that reached full manufacturing capacity in the third quarter of 2023. In May 2022, we announced the opening of “Sella 2”, a 2GWh Li-Ion cell factory in Korea. Sella 2 began producing and shipping cells at the end of 2022 and is expected to gradually increase manufacturing capacity during 2024. In light of the Inflation Reduction Act of 2022 (“IRA”), legislation in the United States that incentivizes the local manufacturing of renewable energy products by providing benefits to installers for the purchase and installation of US-manufactured products, as well as by incentivizing manufacturers of such products domestically, we have begun manufacturing products in the U.S. With the ramp-up of this new site and due to a decrease in demand, this quarter we have reduced capacity in our manufacturing site in China and discontinued manufacturing of our products in Mexico, with the intention to close the Mexico manufacturing site in coming months. We are a leader in the global module-level power electronics or MLPE market. As of September 30, 2023, we shipped approximately 122.9 million power optimizers, 5.5 million inverters and 229.5 thousand residential batteries. Over 3.6 million installations, many of which may include multiple inverters, are currently connected to, and monitored through, our cloud-based monitoring platform. As of September 30, 2023, we shipped approximately 51.7 GW of our DC optimized inverter systems and approximately 1.6 GWh of our residential batteries.

Our revenues for the three months ended September 30, 2023, and 2022 were $725.3 million and $836.7 million, respectively. Gross margin for the three months ended September 30, 2023, and 2022 was 19.7% and 26.5%, respectively. Net loss for the three months ended September 30, 2023 was $61.2 million compared to net income in the amount of $24.7 million for the three months ended September 30, 2022.

Our revenues for the nine months ended September 30, 2023, and 2022 were $2,660.5 million and $2,219.6 million, respectively. Gross margin for the nine months ended September 30, 2023, and 2022 was 28.6% and 26.3%, respectively. Net income for the nine months ended September 30, 2023 and 2022 was $196.7 million and $73.0 million, respectively.

Global Circumstances Influencing our Business and Operations

Disruptions due to the war in Israel

Violence between Hamas and Israel started on October 7th when the terrorist group launched an unprecedented attack on Israel. On October 8th, the Israeli Government declared that the Security Cabinet of the State of Israel approved a war situation in Israel. Approximately 11% of our workforce in Israel, where we are headquartered, have been called into active reserve duty. Recently, Israel’s credit outlook was cut to negative by S&P Global Ratings, which cited risks that the war could spread more widely and have a more pronounced impact on the country’s economy than expected. Our offices and facilities are currently open worldwide, including in Israel, and, to date, we have not had disruptions to our ability to manufacture and deliver products and services to customers. We are prioritizing and reallocating resources between projects to minimize the impact on our business. Due to these recent events, and their ongoing and evolving nature, the extent of the adverse effect on our business operations is still unknown. A prolonged war or an escalation could materially adversely affect our business, financial condition, and results of operations.

Impact of Ukraine’s Conflict on the Energy Landscape

The conflict between Ukraine and Russia, which started in early 2022, and the sanctions and other measures imposed in response to this conflict have increased the level of economic and political uncertainty. While we do not have any meaningful business in Russia or Ukraine and we do not have physical assets in these countries, this conflict has, and may continue to have, a multidimensional impact on the global economy, the energy landscape in general and the global supply chain. The conflict adversely affected the prices of raw materials arriving from Eastern Asia and resulted in an increase in gas and oil prices. Furthermore, various shipment routes were adversely impacted by the conflict resulting in increased shipment lead times and shipping costs for our products. While the impact of this conflict is currently decreasing, a change or escalation of this ongoing conflict, could increase the impacts from the circumstances described above and may have an adverse effect on our business and results of operations.

Inflation Reduction Act

In August 2022, the U.S. government enacted the IRA, which includes several incentives intended to promote clean energy, battery and energy storage, electrical vehicles, and other solar products and is expected to impact our business and operations. As part of such incentives, the IRA will, among other things, extend the investment tax credit (“ITC”) for residential solar installations through 2034 and for commercial installations through 2024 and is therefore expected to increase the demand for solar products. The IRA is expected to further incentivize residential and commercial solar customers and developers due to the inclusion of a tax credit for qualifying energy projects of up to 30%. Since these regulations are still pending administrative guidance from the Internal Revenue Service and U.S. Treasury Department, we will be examining the benefits that may be available to us, such as the availability of tax credits for domestic manufacturers, in the coming months. To the extent that tax benefits or credits may be available to competing technology and not to our technology, our business could be adversely disadvantaged.

Demand for Products

The demand environment for our products experienced a slowdown beginning in the third quarter of 2023 in Europe. During the second part of the third quarter of 2023, we experienced substantial unexpected cancellations and pushouts of existing backlog from our European distributors. We attribute these cancellations and pushouts to high inventory in the channels and slower than expected installation rates. In particular, installation rates for the third quarter were much slower at the end of the summer and in September where traditionally there is a rise in installation rates. As a result, third quarter revenue, gross margin and operating income was below the low end of the prior guidance range. Additionally, the Company anticipates significantly lower revenues in the fourth quarter of 2023 as the inventory destocking process continues.

Key Operating Metrics

In managing our business and assessing financial performance, we supplement the information provided by the financial statements with other operating metrics. These operating metrics are utilized by our management to evaluate our business, measure our performance, identify trends affecting our business and formulate projections. We use metrics relating to shipments of inverters, power optimizers and megawatts to evaluate our sales performance and to track market acceptance of our products.

We provide the “megawatts shipped” and “megawatts hour shipped” metrics, which are calculated based on inverter or battery nameplate capacity shipped, respectively, to show adoption of our system on a nameplate capacity basis. Nameplate capacity shipped is the maximum rated power output capacity of an inverter or battery, and corresponds to our financial results in that higher total nameplate capacities shipped are generally associated with higher total revenues. However, revenues may increase in a non- correlated manner to the “megawatt shipped” metric since other products such as power optimizers, are not accounted for in this metric.

	Three Months Ended September 30, 2023				Nine Months Ended September 30, 2023
	2023		2022		2023		2022
Inverters shipped		273,883		264,515		938,171		704,018
Power optimizers shipped		3,266,487		6,123,479		15,238,543		17,062,684
Megawatts shipped1		3,796		2,703		11,728		7,349
Megawatts hour shipped - residential batteries		121		321		612		671

¹ Excluding residential batteries, based on the aggregate nameplate capacity of inverters shipped during the applicable period. Nameplate capacity is the maximum rated power output capacity of an inverter as specified by the manufacturer.

Comparison of three and nine months ended September 30, 2023, to the three and nine months ended September 30, 2022

Revenues

	Three months ended September 30, 2023 to 2022									Nine months ended September 30, 2023 to 2022
	2023		2022		Change					2023		2022		Change
	(In thousands)
Revenues	$	725,305	$	836,723	$	(111,418	)	(13.3	)%	$	2,660,484	$	2,219,577	$	440,907	19.9	%

Revenues decreased by $111.4 million, or 13.3%, in the three months ended September 30, 2023, as compared to the three months ended September 30, 2022, primarily due to (i) a decrease of $89.0 million related to the number of residential batteries sold mainly in Europe; and (ii) a decrease of $17.2 million related to a decrease in the number of ancillary solar products sold. Revenues from outside of the U.S. comprised 73.0% of our revenues in the three months ended September 30, 2023 as compared to 69.9% in the three months ended September 30, 2022. The decrease in revenues was due to high inventory in the channels and slower than expected installation rates.

The number of power optimizers recognized as revenues decreased by approximately 2.9 million units, or 46.9%, from approximately 6.1 million units in the three months ended September 30, 2022 to approximately 3.3 million units in the three months ended September 30, 2023 as a result of lower demand. The number of inverters recognized as revenues increased by approximately 9.5 thousand units, or 3.7%, from approximately 257.1 thousand units in the three months ended September 30, 2022 to approximately 266.6 thousand units in the three months ended September 30, 2023. The relative increase in inverters shipped vs. the decrease in optimizers shipped this quarter is a result of our ability to catch up inverter production with demand that we were not able to fulfil in previous quarters. The megawatts hour of residential batteries recognized as revenues decreased by approximately 209.2 megawatts hour, or 57.6% from approximately 363.0 in the three months ended September 30, 2022 to approximately 153.7 megawatts hour in the three months ended September 30, 2023, as a result of lower demand.

Our blended Average Selling Price (“ASP”) per watt for solar products excluding residential batteries is calculated by dividing the sales of solar products, excluding the sales of residential batteries, by the name plate capacity of inverters shipped. Our blended ASP per watt for solar products shipped excluding residential batteries decreased by $0.069, or 29.5%, in the three months ended September 30, 2023, as compared to the three months ended September 30, 2022. The decrease in blended ASP per watt is mainly attributed to the increase in the sale of commercial products that are characterized by lower ASP per watt, out of our total solar product mix and a relatively lower number of power optimizers and other solar products shipped compared to the number of inverters shipped, leading to a reduced overall effect on our ASP per watt. This decrease in blended ASP per watt was partially offset by price increases that went into effect gradually during 2022 and the first half of 2023, as well as by the appreciation of the Euro against the U.S. Dollar.

Our blended ASP per watt/hour for residential batteries is calculated by dividing residential battery sales, by the nameplate capacity of residential batteries shipped. Our blended ASP per watt/hour for residential batteries increased by $0.027, or 6.1%, in the three months ended September 30, 2023, as compared to the three months ended September 30, 2022. The increase in blended ASP per watt/hour is mainly attributed to the increase in the sale of one phase batteries that are characterized by higher ASP per watt/hour, as well as the appreciation of the Euro against the U.S. Dollar.

Revenues increased by $440.9 million, or 19.9%, in the nine months ended September 30, 2023 as compared to the nine months ended September 30, 2022, primarily due to an increase of $497.9 million related to an increase in the number of inverters sold, with significant growth in revenues coming from Europe. This increase was partially offset by a decrease of $53.7 million related to a decrease in the number of ancillary solar products sold. Revenues from outside of the U.S. comprised 75.7% of our revenues in the nine months ended September 30, 2023 as compared to 62.7% in the nine months ended September 30, 2022. The increase in revenues in the nine months ended September 30, 2023 was partially offset by a decrease in revenues in the third quarter of 2023 due to unexpected cancellations and pushouts of existing backlog from our European distributors.

The number of power optimizers recognized as revenues decreased by approximately 1.7 million units, or 10.2%, from approximately 17.0 million units in the nine months ended September 30, 2022 to approximately 15.3 million units in the nine months ended September 30, 2023 as a result of lower demand. The number of inverters recognized as revenues increased by approximately 234.7 thousand units, or 33.6%, from approximately 697.7 thousand units in the nine months ended September 30, 2022 to approximately 932.4 thousand units in the nine months ended September 30, 2023. The relative increase in inverters recognized versus the decrease in optimizers recognized in the nine months ended September 30, 2023 was a result of our ability to catch up inverter production with demand that we were not able to fulfil in previous quarters. The megawatts hour of residential batteries recognized as revenues decreased by approximately 19.6 megawatts hour, or 3.0% from approximately 660.8 megawatts hour in the nine months ended September 30, 2022 to approximately 641.2 megawatts hour in the nine months ended September 30, 2023 due to a decrease in demand.

Our blended ASP per watt for solar products shipped excluding residential batteries decreased by $0.054, or 22.1%, in the nine months ended September 30, 2023 as compared to the nine months ended September 30, 2022. The decrease in blended ASP per watt is mainly attributed to a relatively lower number of power optimizers and other solar products shipped compared to the number of inverters shipped, leading to an overall reduction in our ASP per watt as well as due to an increase in the sale of commercial products that are characterized by lower ASP per watt, out of our total solar product mix. This decrease in blended ASP per watt was partially offset by price increases that went into effect gradually during 2022 and in the first half of 2023, as well as by the appreciation of the Euro against the U.S. Dollar.

Our blended ASP per watt/hour for residential batteries decreased by $0.005, or 1.0%, in the nine months ended September 30, 2023, as compared to the nine months ended September 30, 2022. The decrease in blended ASP per watt/hour is mainly attributed to the addition of a three phase battery, which is sold at a lower ASP per watt/hour, to our product portfolio, which was partially offset by the appreciation of the Euro against the U.S. Dollar.

Cost of Revenues and Gross Profit

	Three months ended September 30, 2023 to 2022									Nine months ended September 30, 2023 to 2022
	2023		2022		Change					2023		2022		Change
	(In thousands)
Cost of revenues	$	582,488	$	614,722	$	(32,234	)	(5.2	)%	$	1,900,236	$	1,635,976	$	264,260	16.2	%
Gross profit	$	142,817	$	222,001	$	(79,184	)	(35.7	)%	$	760,248	$	583,601	$	176,647	30.3	%

Cost of revenues decreased by $32.2 million, or 5.2%, in the three months ended September 30, 2023, as compared to the three months ended September 30, 2022, primarily due to:

• a decrease in direct cost of revenues sold of $83.5 million associated mainly with a decrease in the volume of products sold;

• a decrease in customs duties of $5.0 million attributed to the decrease in volumes of products manufactured in China for the U.S. market; and

• a decrease in shipment and logistic costs in an aggregate amount of $3.2 million due to a decrease in shipment rates and a decrease in expedited shipments costs.

These were partially offset by:

 

• an increase in warranty expenses and warranty accruals of $28.0 million associated primarily with an increase in the number of products in our install base as well as an increase in costs related to the different elements of our warranty expenses which include the cost of the products, shipment and other related expenses;

• an increase of $14.0 million in inventory accrual which is mainly attributed to a higher inventory write-down;

• an increase in other production costs of $6.6 million, which is mainly attributed to charges from our contract manufacturers related to the downsizing of our manufacturing in Mexico and China, as well as ramp up costs associated with Sella 2, our Li-Ion battery cell manufacturing facility located in South Korea; and

• an increase in personnel-related costs of $5.6 million related to the expansion of our production, operations, and support headcount, which grew in parallel to our growing install base worldwide and manufacturing volumes which were partially offset by the depreciation of the New Israeli Shekel (“NIS”) against the U.S. dollar.

Gross profit as a percentage of revenue decreased to 19.7% from 26.5% in the three months ended September 30, 2023 as compared to the three months ended September 30, 2022, primarily due to:

• An increase in personnel and manufacturing related costs from the expansion of our infrastructure geared towards accelerated growth;

• an increase in costs related to our existing install base such as warranty expenses, which were divided this quarter by lower revenue resulting in lower gross margin;

• an increase in inventory accrual for impairment of excess inventory;

• an increased portion of sales of commercial products out of our total product mix, which are characterized with lower gross margin; and

• our non-solar businesses, referred to in our financial results as "all other segments", are generally characterized by a lower gross profit which effect was amplified this quarter.

These were partially offset by:

• favorable exchange rates on our sales outside of the U.S.;

• gradual price increases across our product offerings; and

• continued cost reduction efforts.

10

Cost of revenues increased by $264.3 million, or 16.2%, in the nine months ended September 30, 2023 as compared to the nine months ended September 30, 2022, primarily due to:

 

• an increase in direct cost of revenues sold of $112.4 million associated primarily with an increase in the volume of products sold;

• an increase in warranty expenses and warranty accruals of $101.7 million associated primarily with an increase in the number of products in our install base as well as an increase in costs related to the different elements of our warranty expenses which include the cost of the products, shipment and other related expenses;

• an increase of $20.4 million in inventory accrual which is mainly attributed to changes in inventory valuations, and higher inventory accruals related to our initial manufacturing in Sella 2, partially offset by a decrease in inventory write-off related to the discontinuation of our UPS related activities in the comparable period;

• an increase in personnel-related costs of $14.8 million related to the expansion of our production, operations, and support headcount which grew in parallel to our growing install base worldwide; and

• an increase in other production costs of $6.5 million, which is mainly attributed to charges from our contract manufacturers related to the downsizing of our manufacturing sites in China and discontinuance of our manufacturing site in Mexico, as well as ramp up costs associated with Sella 2, our Li-Ion battery cell manufacturing facility located in South Korea.

These were partially offset by:

• a decrease in customs duties of $4.2 million attributed to the decrease in volumes of products manufactured in China for the U.S. market; and

• a decrease in shipment and logistic costs in an aggregate amount of $2.7 million due to a decrease in shipment rates and a decrease in expedited shipments costs.

Gross profit as a percentage of revenue increased to 28.6% from 26.3% in the nine months ended September 30, 2023 as compared to the nine months ended September 30, 2022 primarily due to:

• gradual price increases across our product offerings;

• favorable exchange rates on our sales outside of the U.S.;

• a decrease in shipment rates as well as a reduced portion of expedited shipments out of our total shipments; and

• continued cost reduction efforts. These were partially offset by:

• an increased portion of sales of commercial products out of our total product mix, which are characterized with lower gross margins;

• an increase in warranty expenses and warranty accruals associated primarily with the change in the composition of our install base, as well as an increase in costs related to the different components of our warranty expenses, as reflected in our actual support costs;

• higher revenues from our non-solar businesses, which are generally characterized by a lower gross profit, which effect was amplified this quarter; and

• an increase in inventory accrual for impairment of excess inventory.

Research and development costs increased by $10.4 million or 15.0%, in the three months ended September 30, 2023, compared to the three months ended September 30, 2022, primarily due to:

• an increase in personnel-related costs of $6.4 million resulting from an increase in our research and development headcount as well as salary expenses associated with annual merit increases, which were partially offset by the depreciation of the NIS against the U.S. dollar and employee equity-based compensation. The increase in headcount reflects our continued investment in enhancements of existing products as well as research and development expenses associated with bringing new products to the market; and

• an increase in expenses related to consultants and sub-contractors in an amount of $2.4 million.

Research and development costs increased by $35.6 million or 16.9%, in the nine months ended September 30, 2023, compared to the nine months ended September 30, 2022, primarily due to:

• an increase in personnel-related costs of $21.6 million resulting from an increase in our research and development headcount as well as salary expenses associated with annual merit increases, which were partially offset by the depreciation of the NIS against the U.S. dollar and employee equity-based compensation. The increase in headcount reflects our continued investment in enhancements of existing products as well as research and development expenses associated with bringing new products to the market;

• an increase in expenses related to consultants and sub-contractors in an amount of $7.4 million;

• an increase in depreciation expenses of property and equipment in an amount of $2.7 million; and

• an increase in expenses related to other overhead costs in an amount of $2.5 million.

Sales and marketing expenses decreased by $2.4 million, or 5.6%, in the three months ended September 30, 2023, compared to the three months ended September 30, 2022, primarily due to a decrease in personnel-related costs of $3.2 million as a result of a depreciation of the NIS against the U.S. dollar, a decrease in employee equity-based compensation and a decrease in sales commissions, which were partially offset by an increase in headcount outside of the U.S.

This decrease was partially offset by an increase in expenses related to other marketing activities by $1.0 million.

Sales and marketing expenses increased by $8.5 million, or 7.3%, in the nine months ended September 30, 2023, compared to the nine months ended September 30, 2022, primarily due to:

• an increase in personnel-related costs of $3.0 million as a result of an increase in headcount supporting our growth outside of the U.S, as well as salary expenses associated with annual merit increases and employee equity-based compensation, which were partially offset by the depreciation of the NIS against the U.S. dollar;

• an increase of $1.8 million in expenses related to other marketing activities;

• an increase of $1.4 million in training-related expenses as a result of resuming training activities that had been previously cancelled or postponed due to Covid-19 restrictions in 2022; and

• an increase in expenses related to other overhead costs of $0.9 million.

General and administrative expenses increased by $11.2 million, or 40.0%, in the three months ended September 30, 2023 compared to the three months ended September 30, 2022, primarily due to:

• an increase in expenses related to doubtful debt of $7.6 million;

• an increase in expenses related to consultants and sub-contractors of $2.2 million; and

• an increase in personnel-related costs of $1.4 million resulting from an increase in our general and administrative headcount, as well as salary expenses associated with annual merit increases, which were partially offset by the depreciation of the NIS against the U.S. dollar.

General and administrative expenses increased by $29.4 million, or 35.6%, in the nine months ended September 30, 2023, compared to the nine months ended September 30, 2022, primarily due to:

• an increase in expenses related to consultants and sub-contractors of $11.7 million;

Financial expense, net decreased by $25.2 million in the three months ended September 30, 2023, compared to the three months ended September 30, 2022, primarily due to:

• a decrease of $19.0 million in expenses due to fluctuations in foreign exchange rates, primarily between the Euro and the NIS against the U.S. dollar; and

• an increase of $4.6 million in income related to hedging transactions.

Financial income, net was $19.2 million in the nine months ended September 30, 2023, compared to financial expenses, net in the amount of $52.1 million in the nine months ended September 30, 2022, primarily due to:

• an income of $4.8 million in the nine months ended September 30, 2023, compared to expenses of $55.4 million in the nine months ended September 30, 2022, as a result of fluctuations in foreign exchange rates, primarily between the Euro and the NIS against the U.S. dollar.

• an increase of $9.9 million in interest income and accretion (amortization) of discount (premium) on marketable securities.

Other loss was $0.5 million in the three months ended September 30, 2023, compared to other income, of $7.7 million in the three months ended September 30, 2022, primarily due to a decrease in gain from the sale of an investment in a privately-held company.

Income taxes increased by $1.9 million, or 5.5%, in the three months ended September 30, 2023, as compared to the three months ended September 30, 2022, primarily due to an increase of $11.0 million in current tax expenses mainly attributed to an increase in the Company’s Global Intangible Low Taxed Income (“GILTI”) tax and unfavorable impact of losses in foreign subsidiaries where we do not anticipate a future tax benefit. This increase was partially offset by an increase of $8.3 million in deferred tax income.

Income taxes increased by $46.5 million, or 87.7%, in the nine months ended September 30, 2023, as compared to the nine months ended September 30, 2022, primarily due to an increase of $61.2 million in current tax expenses mainly attributed to an increase in profit before tax in our foreign subsidiaries. This increase was partially offset by an increase of $14.4 million in deferred tax income.

As a result of the factors discussed above, net income increased by $123.8 million, or 169.7% in the nine months ended September 30, 2023 as compared to the nine months ended September 30, 2022.

Liquidity and Capital Resources

The following table shows our cash flows from operating activities, investing activities, and financing activities for the stated

periods:

	Three Months Ended September 30,						Nine Months Ended September 30,
	2023			2022			2023			2022
	(In thousands)
Net cash provided by (used in) operating activities	$	40,585		$	5,558		$	(40,203	)	$	(80,016	)
Net cash used in investing		(43,733	)		(54,581	)		(188,187	)		(380,514	)
Net cash provided by (used in) financing activities		(1,164	)		(1,271	)		(11,305	)		647,135
Increase (decrease) in cash and cash equivalents	$	(4,312	)	$	(50,294	)	$	(239,695	)	$	186,605

As of September 30, 2023, our cash and cash equivalents were $551.1 million. This amount does not include $913.4 million invested in available-for-sale marketable securities and $0.3 million invested in restricted bank deposits. Our principal uses of cash are for funding our operations, capital expenditures, other working capital requirements, other investments and any potential future share repurchases. As of September 30, 2023, we have open commitments for capital expenditures in an amount of approximately $120.6 million. These commitments mainly reflect purchases of automated assembly lines and other machinery related to our manufacturing and operations. We also have purchase obligations in the amount of $1,116.6 million related to raw materials and commitments for the future manufacturing of our products.

We believe our cash and cash equivalents, and available-for-sale marketable securities will be sufficient to meet our anticipated cash needs for at least the next 12 months as well as in the longer term, including the self-funding of our capital expenditure and operational commitments.

Operating Activities

Operating cash flows consists primarily of net income adjusted for certain non-cash items and changes in assets and liabilities. Cash used in operating activities decreased by $39.8 million in the nine months ended September 30, 2023 as compared to the nine months ended September 30, 2022, mainly due to higher net income adjusted for certain non-cash items. This was partially offset by higher operating working capital requirements, specifically, an increase in inventory procurement and manufacturing.

Investing Activities

Investing cash flows consist primarily of capital expenditures, investment in, sales and maturities of available for sale marketable securities, investment and withdrawal of bank deposits and restricted bank deposits, cash used for acquisitions and disbursements and receipts from collections of loans made by the Company. Cash used in investing activities decreased by $192.3 million in the nine months ended September 30, 2023, as compared to the nine months ended September 30, 2022, primarily driven by a decrease of $247.0 million in investments in available-for-sale marketable securities, an increase of $16.2 million in proceeds provided by sales and maturities of available-for-sale marketable securities as well as an increase of $6.8 million in proceeds provided by government grants in relation to capital expenditures. This decrease in cash used in investing activities was partially offset by a $24.2 million decrease in proceeds provided by the sale of a privately-held company, an increase of $16.7 million in cash used for a business combination, an increase of $13.0 million in disbursements of loans made by the company, an increase of $11.2 million in the purchase of intangible assets and a $8.0 million increase in investments in privately-held companies.

16

Financing Activities

Financing cash flows consist primarily of proceeds from the sale of shares of common stock in a public offering and employee equity incentive plans. Cash used in financing activities in the nine months ended September 30, 2023 was $11.3 million compared to $647.1 million cash provided by financing activities in the nine months ended September 30, 2022, primarily due to a

$650.5 million decrease in cash provided by the issuance of common stock, net through a secondary public offering which occurred in March 2022 and a $27.3 million decrease in proceeds provided by the exercise of stock-based awards. This was partially offset by a decrease of $19.3 million in withholding taxes remitted to the tax authorities related to the exercise of stock-based awards.

Secondary Public Offering

On March 17, 2022, we offered and sold 2,300,000 shares of the Company’s common stock at a public offering price of $295.00 per share. The net proceeds to the Company after underwriters’ discounts and commissions and offering costs were $650.5 million. We intend to use the proceeds from the public offering for general corporate purposes, which may include acquisitions. See Note 15b to our condensed consolidated financial statements for more information.

Share Repurchases

On November 1, 2023, we announced the approval by the Board of Directors of a share repurchase program which authorizes the repurchase of up to $300 million of the Company’s common stock. Under the share repurchase program, repurchases can be made using a variety of methods, which may include open market purchases, block trades, privately negotiated transactions, accelerated share repurchase programs and/or a non-discretionary trading plan or other means, including through 10b5-1 trading plans, all in compliance with the rules of the SEC and other applicable legal requirements. The timing, manner, price and amount of any common share repurchases under the share repurchase program are determined by the Company in its discretion and depend on a variety of factors, including legal requirements, price and economic and market conditions. The program does not obligate SolarEdge to acquire any amount of common stock, it may be suspended, extended, modified, discontinued or terminated at any time at the Company’s discretion without prior notice, and will expire on December 31, 2024.

Critical Accounting Policies and Significant Management Estimates

Management believes that there have been no significant changes during the nine months ended September 30, 2023 to the items that we disclosed as our critical accounting policies and estimates in MD&A in our Annual Report on Form 10-K for the fiscal year ended December 31, 2022, except as mentioned in Note 1, “General” (if any).

 

ITEM 3. Quantitative and Qualitative Disclosures About Market Risk

We are exposed to market risk in the ordinary course of our business. Market risk represents the risk of loss that may impact our financial position due to adverse changes in financial market prices and rates. Our market risk exposure is primarily a result of fluctuations in foreign currency exchange rates, customer concentrations, interest rates and commodity prices . We do not hold or issue financial instruments for trading purposes.

Foreign Currency Exchange Risk

Approximately 70.9% and 59.5% of our revenues for the nine months ended September 30, 2023, and 2022, respectively, were earned in non U.S. dollar denominated currencies, principally the Euro. Our expenses are generally denominated in the currencies in which our operations are located, primarily the U.S. dollar, New Israeli Shekel (“NIS”), Euro, and to a lesser extent, the South Korean Won (“KRW”). Our NIS denominated expenses consist primarily of personnel and overhead costs. Our consolidated results of operations and cash flows are, therefore, subject to fluctuations due to changes in foreign currency exchange rates and may be adversely affected in the future due to changes in foreign exchange rates. A hypothetical 10% change in foreign currency exchange rates between the Euro and the U.S. dollar would increase or decrease our net income by $198.5 million for the nine months ended September 30, 2023. A hypothetical 10% change in foreign currency exchange rates between the NIS and the U.S. dollar would increase or decrease our net income by $30.3 million for the nine months ended September 30, 2023.

17

For purposes of our consolidated financial statements, local currency assets and liabilities are translated at the rate of exchange to the U.S. dollar on the balance sheet date, and local currency revenues and expenses are translated at the exchange rate as of the date of the transaction or at the average exchange rate to the U.S. dollar during the reporting period.

To date, we have used derivative financial instruments, specifically foreign currency forward contracts and put and call options, to manage exposure to foreign currency risks by hedging portions of the anticipated payroll payments denominated in NIS. These derivative instruments are designated as cash flow hedges.

In addition, from time to time we enter into derivative financial instruments to hedge the Company’s exposure to currencies other than the U.S. dollar, mainly forward contracts to sell Euro and AUD for U.S. dollars. These derivative instruments are not designated as cash flow hedges.

Concentrations of Major Customers

Our trade accounts receivables potentially expose us to a concentration of credit risk with our major customers. As of September 30, 2023, two major customers jointly accounted for approximately 37.3% of our consolidated trade receivables, net balance. As of December 31, 2022, two major customers jointly accounted for approximately 27.7% of our consolidated trade receivables, net balance. For the three months ended September 30, 2023 two major customers jointly accounted for approximately 27.3% of our total revenues. For the three months ended September 30, 2022 two major customers accounted for approximately 27.4% of our total revenues. For the nine months ended September 30, 2023 two major customers jointly accounted for approximately 25.4% of our total revenues. For the nine months ended September 30, 2022 one major customer accounted for approximately 20.1% of our total revenues.

Commodity Price Risk

We are subject to risk from fluctuating market prices of certain commodity raw materials which are used in our products, including Copper, Lithium, Nickel and Cobalt. Prices of these raw materials may be affected by supply restrictions or other market factors from time to time, and we do not enter into hedging arrangements to mitigate commodity risk. Significant price changes for these raw materials could reduce our operating margins if we are unable to recover such increases from our customers, and could harm our business, financial condition, and results of operations.

ITEM 4.  Controls and Procedures.

Disclosure Controls and Procedures

Our management, with the participation of our chief executive officer and chief financial officer, evaluated the effectiveness of our disclosure controls and procedures pursuant to Rule 13a-15 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), as of September 30, 2023. In designing and evaluating the disclosure controls and procedures, management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. In addition, the design of disclosure controls and procedures must reflect the fact that there are resource constraints and that management is required to apply its judgment in evaluating the benefits of possible controls and procedures relative to their costs.

Based on that evaluation, our chief executive officer and chief financial officer concluded, as of September 30, 2023, that our disclosure controls and procedures were effective and operating to provide reasonable assurance that information we are required to disclose in reports that we file or submit under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in SEC rules and forms, and to provide reasonable assurance that such information is accumulated and communicated to our management, including our chief executive officer and chief financial officer, as appropriate, to allow timely decisions regarding required disclosure.

Changes in Internal Control over Financial Reporting

There have been no changes in our internal control over financial reporting (as defined in Rule 13a-15(f) of the Exchange Act) that occurred during the third fiscal quarter of 2023 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

18

PART II. OTHER INFORMATION.

ITEM 1. Legal Proceedings

In the normal course of business, we may from time to time be named as a party to various legal claims, actions and complaints (including as a result of initiating such legal claims, action or complaints on behalf of the Company), including the matters described in Note 16 – “Commitments and Contingent Liabilities” and Note 22 -- “Subsequent Events” to our condensed consolidated financial statements in this report and in Item 3 – “Legal Proceedings” of our Annual Report on Form 10-K for the period ended December 31, 2022. It is impossible to predict with certainty whether any resulting liability from any such legal claims, actions or complaints would have a material adverse effect on our financial position, results of operations or cash flows.

ITEM 1A. Risk Factors

In addition to the other information set forth in this report, you should carefully consider the risk set forth below and the risk factors as described in Part I, Item 1A, ”Risk Factors”, in our Annual Report on Form 10-K for the year ended December 31, 2022. Except as set forth below, there were no material changes to the risk factors disclosed in our Annual Report on Form 10-K for the year ended December 31, 2022.

We have experienced and may continue to experience disruption to our business operations as a result of war and hostilities in Israel

Violence between Hamas and Israel started on October 7th when the terrorist group launched an unprecedented attack on Israel. On October 8, 2023 the Israeli Government declared that the Security Cabinet of the State of Israel approved a war situation in Israel. Since our headquarters and most of our employees operate from Israel, the state of war has disrupted and is continuing to disrupt our business operations. This situation has impacted the availability of our workforce, as approximately 11% of our workforce in Israel, where we are headquartered, have been called into active reserve duty. Several of our employees who reside close to the southern or northern boarders of Israel have been forced to evacuate their homes and have relocated to temporary housing. Since the education system is partially operating many of our employees with small children are working from home. Due to the recency of these events, and their ongoing and evolving nature, the extent of the adverse effect on our business operations is still unknown. While our offices and facilities are open worldwide, including in Israel, and, to date, we have not had disruptions to our ability to manufacture and deliver products and services to customers a prolonged war or an escalation of the current conditions in Israel could materially adversely affect our business, financial condition, and results of operations.

ITEM 2. Unregistered Sales of Equity Securities and Use of Proceeds.

None

ITEM 3. Defaults upon Senior Securities.

None

ITEM 4. Mine Safety Disclosures

Not applicable.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

GENERAL

NOTE 1:       GENERAL

a. SolarEdge Technologies Inc. (the “Company”) and its subsidiaries design, develop, and sell an intelligent inverter solution designed to maximize power generation at the individual photovoltaic (“PV”) module level while lowering the cost of energy produced by the solar PV system and providing comprehensive and advanced safety features. The Company’s products consist mainly of (i) power optimizers designed to maximize energy throughput from each and every module through constant tracking of Maximum Power Point individually per module, (ii) inverters which invert direct current (DC) from the PV module to alternating current (AC) including the Company’s Energy Hub inverter which supports, among other things, connection to a DC-coupled battery for full or partial home backup, and optional connection to the Company's smart EV charger, (iii) a remote cloud-based monitoring platform, that collects and processes information from the power optimizers and inverters to enable customers and system owners, to monitor and manage the solar PV system (iv) a residential storage and backup solution which includes a company designed and manufactured lithium-ion DC-coupled battery that is used to increase energy independence and maximize self-consumption for homeowners including a battery, and (v) additional smart energy management solutions.

The Company and its subsidiaries sell products worldwide through large distributors, electrical equipment wholesalers, as well as directly to large solar installers and engineering, procurement, and construction firms.

b. The Company has expanded its activity to other areas of smart energy technology organically and through acquisitions. The Company now offers a variety of energy solutions, which include lithium-ion cells, batteries, and energy storage systems (“Energy Storage”), full powertrain kits for electric vehicles, or EVs (“e-Mobility”), as well as automated machines for industrial use (“Automation Machines”).

On April 6, 2023, the Company completed the acquisition of all outstanding shares of Hark Systems Ltd. ("Hark"), a UK-based energy IoT company for the commercial and industrial ("C&I") sector, which operates under the newly established consulting segment (see note 2).

c. Basis of Presentation:

The unaudited condensed consolidated financial statements and accompanying notes have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”). In management’s opinion, the unaudited condensed consolidated financial statements reflect all adjustments of a normal recurring nature that are necessary for a fair presentation of the results for the interim periods presented. The Company’s interim period results do not necessarily indicate the results that may be expected for any other interim period or for the full fiscal year.

The significant accounting policies applied in the annual consolidated financial statements of the Company as of December 31, 2022, contained in the Company’s Annual Report on Form 10-K filed with the SEC on February 22, 2023, have been applied consistently in these unaudited interim condensed consolidated financial statements. Certain prior year amounts have been reclassified to conform to current year presentation.

d. Use of estimates:

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, costs and expenses and related disclosures in the accompanying notes. Actual results and outcomes may differ from management’s estimates and assumptions due to risks and uncertainties.

e. Concentrations of supply risks:

The Company depends on two contract manufacturers and several limited or single source component suppliers. Reliance on these vendors makes the Company vulnerable to possible capacity constraints and reduced control over component availability, delivery schedules, manufacturing yields, and costs.

As of September 30, 2023, and December 31, 2022, two contract manufacturers collectively accounted for 40.9% and 34.3% of the Company’s total trade payables, net, respectively.

In the second quarter of 2022, the Company announced the opening of “Sella 2”, a two gigawatt-hour (GWh) Li-Ion battery cell manufacturing facility located in South Korea. Sella 2 began producing and shipping cells at the end of 2022 and is expected to reach full manufacturing capacity in early 2024. Sella 2 is the Company's second owned manufacturing facility following the establishment of Sella 1 in 2020. Sella 1 is the Company's manufacturing facility in the North of Israel that produces power optimizers and inverters for the Company's solar activities.

f. New accounting standards updates:

From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board ("FASB") or other standard setting bodies are adopted by the Company as of the specified effective date. The Company believes that the impact of recently issued or newly effective standards were not applicable to the Company, did not have a material impact on the condensed consolidated financial statements or are not expected to have a material impact on the condensed consolidated financial statements.

Business Combinations [Abstract]

BUSINESS COMBINATIONS

NOTE 2:       BUSINESS COMBINATIONS

On April 6, 2023, the Company completed the acquisition of all outstanding shares of Hark Systems Ltd. ("Hark"), a UK-based energy IoT company for the commercial and industrial ("C&I") sector for approximately $18,346 in cash. Hark's platform is expected to enable the Company to offer its commercial and industrial customers expanded capabilities in energy management and connectivity, including identification of potential energy savings, detection of anomalies in assets’ energy consumption, and optimization of energy usage and carbon emissions through load orchestration and storage control.

Pursuant to ASC 805, "Business Combination", the Company accounted for the Hark acquisition as a business combination using the acquisition method of accounting. Identifiable assets and liabilities of Hark, including identifiable intangible assets, were recorded based on their estimated fair values as of the date of the closing of the acquisition. The excess of the purchase price over the fair value of the net assets acquired was recorded as goodwill. The Company recorded preliminary estimates for the fair value of assets acquired and liabilities assumed as of the acquisition date. Such preliminary valuation required estimates and assumptions including, but not limited to, estimating future cash flows and direct costs in addition to developing the appropriate discount rates and current market profit margins. The Company’s management believes the fair values recognized for the assets acquired and the liabilities assumed were based on reasonable estimates and assumptions.

The following table summarizes the preliminary fair values estimation of assets acquired and liabilities assumed as of the date of the acquisition:

	Amount			Weighted Average Useful Life (In years)
Cash	$	448
Net liabilities assumed		(1,837	)
Identified intangible assets:
Current technology		6,576			5
Customer relationships		283			1
Trade name		610			5
Goodwill		12,266
Total	$	18,346

Acquisition costs were immaterial and are included in general and administrative expenses in the consolidated statements of income.

Goodwill generated from this acquisition was primarily attributable to the assembled workforce and expected post-acquisition synergies from combining Hark platform with the Company's product offering to its commercial and industrial customers. All of the Goodwill was assigned to the new Consulting segment (see Note 21). Goodwill was not deductible for tax purposes. The fair values of technology, customer relationships and trade name were derived by applying the multi-period excess earnings method, with-and-without method, and the relief-from-royalty method, respectively, all of which are under the income approach whose underlying inputs are considered Level 3. The fair values assigned to assets acquired and liabilities assumed were based on management's estimates and assumptions.

The results of Hark have been included in the Company's consolidated statements of income (loss) since the acquisition date and are not material. Pro forma financial information has not been presented because the impact of the acquisition was not material to the Company's statement of income.

DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

NOTE 9:       DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

During the nine months ended September 30, 2023, the Company instituted a foreign currency cash flow hedging program to reduce the risk of a forecasted increase in the value of foreign currency cash flows, resulting from payment of salaries in Israeli currency, the New Israeli Shekels (“NIS”). The Company hedges portions of the anticipated payroll denominated in NIS for a period of one to nine months with hedging contracts. These hedging contracts are designated as cash flow hedges, as defined by ASC 815 and are all effective hedges.

As of September 30, 2023, the Company entered into forward contracts and put and call options to sell U.S. dollars (“USD”) for NIS in the amount of approximately NIS 38 million and NIS 622 million, respectively.

In addition to the above-mentioned cash flow hedge transactions, the Company occasionally enters into derivative instrument arrangements to hedge the Company’s exposure to currencies other than the USD. These derivative instruments are not designated as cash flow hedges, as defined by ASC 815, and therefore all gains and losses, resulting from fair value remeasurement, were recorded immediately in the statement of income, under "Financial income (expense), net".

As of September 30, 2023, the Company entered into put and call option contracts to sell Euro ("EUR") for USD in the amount of EUR 120 million.

The Company classifies cash flows related to its hedging as operating activities in its condensed consolidated statement of cash flows.

The fair values of outstanding derivative instruments were as follows:

	Balance sheet location	September 30, 2023			December 31, 2022
Derivative assets of options and forward contracts:
Designated cash flow hedges	Prepaid expenses and other current assets	$	87		$	-

CONVERTIBLE SENIOR NOTES

NOTE 14:      CONVERTIBLE SENIOR NOTES

On September 25, 2020, the Company sold $632,500 aggregate principal amount of its 0.00% convertible senior notes due 2025 (the “Notes”). The Notes were sold pursuant to an indenture, dated September 25, 2020 (the “Indenture”), between the Company and U.S. Bank National Association, as trustee. The Notes do not bear regular interest and mature on September 15, 2025, unless earlier repurchased or converted in accordance with their terms. The Notes are general senior unsecured obligations of the Company. Holders may convert their Notes prior to the close of business on the business day immediately preceding June 15, 2025 in multiples of $1,000 principal amount, only under the following circumstances: (1) during any calendar quarter commencing after the calendar quarter ending on December 31, 2020 (and only during such calendar quarter), if the last reported sale price of the common stock for at least 20 trading days (whether or not consecutive) during the period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day; (2) during the five-business-day period after any five consecutive trading day period in which the trading price per $1,000 principal amount of the Notes for each trading day of that five consecutive trading day period was less than 98% of the product of the last reported sale price of the common stock and the conversion rate on each such trading day; or (3) upon the occurrence of specified corporate events as described in the Indenture. In addition, holders may convert their Notes, in multiples of $1,000 principal amount, at their option at any time beginning on or after June 15, 2025, and prior to the close of business on the second scheduled trading day immediately preceding the stated maturity date of the Notes, without regard to the foregoing circumstances. The initial conversion rate for the Notes was 3.5997 shares of common stock per $1,000 principal amount of Notes, which is equivalent to an initial conversion price of approximately $277.80 per share of common stock, subject to adjustment upon the occurrence of certain specified events as set forth in the Indenture.

Upon conversion, the Company may choose to pay or deliver, as the case may be, cash, shares of common stock, or a combination of cash and shares of common stock.

In addition, upon the occurrence of a fundamental change (as defined in the Indenture), holders of the Notes may require the Company to repurchase all or a portion of their Notes, in multiples of $1,000 principal amount, at a repurchase price of 100% of the principal amount of the Notes, plus any accrued and unpaid special interest to, but excluding the fundamental change repurchase date. If certain fundamental changes referred to as make-whole fundamental changes occur, the conversion rate for the Notes may be increased.

The Convertible Senior Notes consisted of the following as of September 30, 2023 and December 31, 2022:

	September 30,  2023			December 31,  2022

Share-based Payment Arrangement [Abstract]

STOCK CAPITAL

NOTE 15:      STOCK CAPITAL

a. Common stock rights:

Common stock confers upon its holders the right to receive notice of, and to participate in, all general meetings of the Company, where each share of common stock shall have one vote for all purposes, to share equally, on a per share basis, in bonuses, profits, or distributions out of fund legally available therefor, and to participate in the distribution of the surplus assets of the Company in the event of liquidation of the Company.

b. Secondary public offering:

On March 17, 2022, the Company offered and sold 2,300,000 shares of the Company’s common stock, at a public offering price of $295.00 per share. The shares of Common Stock were issued and sold in a registered offering pursuant to the underwriting agreement dated March 17, 2022, among the Company, Goldman Sachs & Co. LLC, J.P. Morgan Securities LLC, and Morgan Stanley & Co. LLC (the “Underwriting Agreement”). All of the offered shares were issued at closing, including 300,000 shares of Common Stock that were issued and sold pursuant to the underwriters’ option to purchase additional shares under the Underwriting Agreement, which was exercised in full on March 18, 2022.

The net proceeds to the Company were $650,526 after deducting underwriters' discounts of $27,140 and commissions of $834.

c. Equity Incentive Plans:

The Company’s 2007 Global Incentive Plan (the “2007 Plan”) was adopted by the board of directors on August 30, 2007. The 2007 Plan terminated upon the Company’s IPO on March 31, 2015 and no further awards may be granted thereunder. All outstanding awards will continue to be governed by their existing terms and 379,358 available options for future grants were transferred to the Company’s 2015 Global Incentive Plan (the “2015 Plan”) and are reserved for future issuances under the 2015 plan. The 2015 Plan became effective upon the consummation of the IPO. The 2015 Plan provides for the grant of options, restricted stock units ("RSU"), performance stock units ("PSU"), and other share-based awards to directors, employees, officers, and non-employees of the Company and its subsidiaries. As of September 30, 2023, a total of 20,853,755 shares of common stock were reserved for issuance pursuant to stock awards under the 2015 Plan (the “Share Reserve”), an aggregate of 11,845,915 shares are still available for future grants.

The Share Reserve will automatically increase on January 1^st of each year during the term of the 2015 Plan, commencing on January 1^st of the year following the year in which the 2015 Plan becomes effective, in an amount equal to 5% of the total number of shares of capital stock outstanding on December 31^st of the preceding calendar year; provided, however, that the Company’s board of directors may determine that there will not be a January 1^st increase in the Share Reserve in a given year or that the increase will be less than 5% of the shares of capital stock outstanding on the preceding December 31^st.

The Company granted under its 2015 Plan, PSU awards to certain employees and officers which vest upon the achievement of certain performance or market conditions subject to their continued employment with the Company.

The market condition for the PSUs is based on the Company’s total shareholder return ("TSR") compared to the TSR of companies listed in the S&P 500 index over a one to three year performance period. The Company uses a Monte-Carlo simulation to determine the grant date fair value for these awards, which takes into consideration the market price of a share of the Company’s common stock on the date of grant less the present value of dividends expected during the requisite service period, as well as the possible outcomes pertaining to the TSR market condition. The Company recognizes such compensation expenses on an accelerated vesting method.

The aggregate maximum number of shares of common stock that may be issued on the exercise of incentive stock options is 10,000,000. As of September 30, 2023, an aggregate of 8,617,974 options are still available for future grants under the 2015 Plan.

A summary of the activity in stock options and related information is as follows:

	Number of options			Weighted average exercise price		Weighted average remaining contractual term in years		Aggregate intrinsic Value
Outstanding as of December 31, 2022		339,029		$	50.64		4.86	$	79,414
Exercised		(11,804	)		15.41		-		2,789
Outstanding as of September 30, 2023		327,225		$	51.91		4.20	$	28,935
Vested and expected to vest as of September 30, 2023		326,961		$	51.79		4.20	$	28,931
Exercisable as of September 30, 2023		312,711		$	44.70		4.08	$	28,736

The intrinsic value is the amount by which the closing price of the Company’s common stock on September 30, 2023 of $129.51 or the price on the day of exercise exceeds the exercise price of the stock options multiplied by the number of in-the-money options.

A summary of the activity in the RSUs and related information is as follows:

	Number of RSUs			Weighted average grant date fair value
Unvested as of December 31, 2022		1,488,515		$	232.05

d. Employee Stock Purchase Plan ("ESPP"):

The Company adopted an ESPP effective upon the consummation of the IPO. As of September 30, 2023, a total of 4,150,380 shares were reserved for issuance under this plan. The number of shares of common stock reserved for issuance under the ESPP will increase automatically on January 1^st of each year, for ten years, by the lesser of 1% of the total number of shares of the Company’s common stock outstanding on December 31st of the preceding calendar year or 487,643 shares. However, the Company’s board of directors may reduce the amount of the increase in any particular year at their discretion, including a reduction to zero.

The ESPP is implemented through an offering every six months. According to the ESPP, eligible employees may use up to 15% of their salaries to purchase common stock up to an aggregate limit of $15 per participant for every six months plan. The price of an ordinary share purchased under the ESPP is equal to 85% of the lower of the fair market value of the ordinary share on the subscription date of each offering period or on the purchase date.

As of September 30, 2023, 780,370 shares of common stock have been purchased under the ESPP.

As of September 30, 2023, 3,370,010 shares of common stock were available for future issuance under the ESPP.

In accordance with ASC No. 718, the ESPP is compensatory and, as such, results in recognition of compensation cost.

Commitments and Contingencies Disclosure [Abstract]

COMMITMENTS AND CONTINGENT LIABILITIES

NOTE 16:     COMMITMENTS AND CONTINGENT LIABILITIES

a. Guarantees:

As of September 30, 2023, contingent liabilities exist regarding guarantees in the amounts of $5,804, and $1,821 in respect of office rent lease agreements and other transactions, respectively.

b. Contractual purchase obligations:

The Company has contractual obligations to purchase goods and raw materials. These contractual purchase obligations relate to inventories and other purchase orders, which cannot be canceled without penalty. In addition, the Company acquires raw materials or other goods and services, including product components, by issuing authorizations to its suppliers to purchase materials based on its projected demand and manufacturing needs.

As of September 30, 2023, the Company had non-cancellable purchase obligations totaling approximately $1,116,593, out of which the Company recorded a provision for loss in the amount of $13,463.

As of September 30, 2023, the Company had contractual obligations for capital expenditures totaling approximately $120,572. These commitments reflect purchases of automated assembly lines and other machinery related to the Company’s general manufacturing process and mainly to its new manufacturing site in the U.S.

c. Legal claims:

From time to time, the Company may be involved in various claims and legal proceedings. The Company reviews the status of each matter and assesses its potential financial exposure. If the potential loss from any claim or legal proceeding is considered probable and the amount can be reasonably estimated, the Company accrues a liability for the estimated loss. These accruals are reviewed at least quarterly and adjusted to reflect the impact of negotiations, settlements, rulings, advice of legal counsel, and other information and events pertaining to a particular matter.

In September 2018, the Company’s German subsidiary, SolarEdge Technologies GmbH, received a complaint filed by competitor SMA Solar Technology AG (“SMA”). The complaint, filed in the District Court Düsseldorf, Germany, alleged that SolarEdge's 12.5kW - 27.6kW inverters infringed on two of the plaintiff’s patents. SMA asserted a value in dispute of EUR 5.5 million (approximately $5,830) for both patents. The Company challenged the validity of both patents and the first patent was invalidated and SMA’s appeal on the matter was denied in January 2023. In August 2021, the German Patent Court rendered SMA's second patent invalid, and this invalidity has been appealed by SMA. In May 2023 the Federal Supreme Court as final instance in the nullity proceedings revoked the second patent, and SMA withdrew its infringement complaint.

On July 28, 2022, the Company and its subsidiary SolarEdge Technologies Ltd were served with complaints filed by Ampt LLC ("Ampt") in the International Trade Commission (the “Commission”) pursuant to Section 337 of the Tariff Act of 1930, as amended, and related lawsuits in the District Court for the District of Delaware alleging patent infringement against the Company. On May 9, 2023, Ampt and the Company entered into a settlement agreement pursuant to which the parties agreed to dismiss all proceedings related to the complaints, and the parties have granted each other 10-year cross-licenses for certain intellectual property.

As of September 30, 2023, an immaterial amount for legal claims was recorded in accrued expenses and other current liabilities.

Income Taxes [Abstract]

INCOME TAXES

NOTE 19:      INCOME TAXES

The effective tax rate for the three months ended September 30, 2023, and 2022 was (143.6)% and 58.0%, respectively.

The change in effective tax rate in the three months ended September 30, 2023 compared to the corresponding period in 2022 is mainly due to the IRC Section 174 R&D capitalization, and other expenses not recognized for GILTI purposes, which did not decrease in line with the decrease in our taxable income, as well as unfavorable impact of losses in foreign subsidiaries where we do not anticipate a future tax benefit.

The effective tax rate for the nine months ended September 30, 2023 and 2022 was 33.6% and 42.1%, respectively.

The lower tax rate in the nine months ended September 30, 2023 compared to the corresponding period in 2022 is mainly due to the fact that the Company's income before tax, most of which is subject to tax rates lower than the US statutory rate, increased. Conversely, the IRC Section 174 R&D capitalization, and other expenses not recognized for GILTI purposes, did not increase in the same proportion.

As of September 30, 2023, and December 31, 2022, unrecognized tax benefits were $3,155 and $2,756, respectively. If recognized, such benefits would favorably affect the Company’s effective tax rate.

The Company accrues interest and penalties related to unrecognized tax benefits in its provision for income taxes. The total amount of penalties and interest were immaterial as of September 30, 2023, and December 31, 2022.

In August 2022, the U.S. government enacted the Inflation Reduction Act of 2022 (the “IRA”), which includes several incentives intended to promote clean energy, battery and energy storage, electrical vehicles, and other solar products, and is expected to impact our business and operations. As part of such incentives the IRA, will among other things, extend the investment tax credit (“ITC”) through 2034 and is therefore expected to increase the demand for solar products. The IRA is expected to further incentivize residential and commercial solar customers and developers due to the inclusion of a tax credit for qualifying energy projects of up to 30%. Since these regulations are new and their implementation is still pending administrative guidance from the Internal Revenue Service and U.S. Treasury Department, the Company will be examining the benefits that may be available to it, such as the availability of tax credits for domestic manufacturers, in the coming months. During the third quarter, the Company began manufacturing inverters in the U.S..

Segment Reporting [Abstract]

SEGMENT INFORMATION

NOTE 21:      SEGMENT INFORMATION

Following the discontinuation of Critical Power in June 2022, the Company operates in five different operating segments: Solar, Energy Storage, e-Mobility, Automation Machines, and the newly formed Consulting segment.

The Company’s Chief Executive Officer, who is the chief operating decision maker (“CODM”), makes resource allocation decisions and assesses performance based on financial information presented on a consolidated basis, accompanied by disaggregated information about revenues and contributed profit by the operating segments.

The Company does not allocate to its operating segments revenue recognized due to advance payments received for performance obligations that extend for a period greater than one year, related to ASC 606, “Revenue from Contracts with Customers”.

Segment profit is comprised of gross profit for the segment less operating expenses that do not include amortization of purchased intangible assets, impairments of goodwill and intangible assets, stock based compensation expenses, and certain other items.

The Company manages its assets on a group basis, not by segments, as many of its assets are shared or co-mingled. The Company’s CODM does not regularly review asset information by segments and, therefore, the Company does not report asset information by segment.

The Company identified one operating segment as reportable – the Solar segment. The other operating segments are insignificant individually and therefore their results are presented together under “All other”.

The Solar segment includes the design, development, manufacturing, and sales of an intelligent inverter solution designed to maximize power generation at the individual PV module level and a residential storage solution, compatible with the Company’s Energy Hub inverter, intended to store and supply power for back-up and to maximize self-consumption. The Solar segment solution consists mainly of the Company’s power optimizers, inverters, batteries, and cloud‑based monitoring platform.

The “All other” category includes the design, development, manufacturing, and sales of energy storage products, e-Mobility products, automated machines, and consulting services.

The following tables present information on reportable segments profit (loss) for the period presented:

Subsequent Events [Abstract]

SUBSEQUENT EVENTS

NOTE 22:      SUBSEQUENT EVENTS

1. On November 1, 2023, the Company announced the approval by the Board of Directors of a share repurchase program which authorizes the repurchase of up to $300 million of the Company’s common stock. Under the share repurchase program, repurchases can be made using a variety of methods, which may include open market purchases, block trades, privately negotiated transactions, accelerated share repurchase programs and/or a non-discretionary trading plan or other means, including through 10b5-1 trading plans, all in compliance with the rules of the SEC and other applicable legal requirements. The timing, manner, price and amount of any common share repurchases under the share repurchase program are determined by the Company in its discretion and depend on a variety of factors, including legal requirements, price and economic and market conditions. The program does not obligate the Company to acquire any amount of common stock, it may be suspended, extended, modified, discontinued or terminated at any time at the Company’s discretion without prior notice, and will expire on December 31, 2024.

2. In October 2023, the Company decided to discontinue its light commercial e-Mobility ("LCV") activity related to the supply of products to its sole customer.

3. On November 3, 2023, Daphne Shen, a purported stockholder of the Company, filed a proposed class action complaint for violation of federal securities laws, individually and putatively on behalf of all others similarly situated, in the U.S District Court of the Southern District of New York against the Company, the Company’s CEO and the Company’s CFO. The complaint alleges that the Company violated various securities laws and seeks class certification, damages, interest, attorneys’ fees, and other relief. Due to the early stage of this proceeding, we cannot reasonably estimate the potential range of loss, if any. The Company disputes the allegations of wrongdoing and intends to vigorously defend against them.

GENERAL (Policies)

9 Months Ended

Sep. 30, 2023

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation

c. Basis of Presentation:

The unaudited condensed consolidated financial statements and accompanying notes have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”). In management’s opinion, the unaudited condensed consolidated financial statements reflect all adjustments of a normal recurring nature that are necessary for a fair presentation of the results for the interim periods presented. The Company’s interim period results do not necessarily indicate the results that may be expected for any other interim period or for the full fiscal year.

The significant accounting policies applied in the annual consolidated financial statements of the Company as of December 31, 2022, contained in the Company’s Annual Report on Form 10-K filed with the SEC on February 22, 2023, have been applied consistently in these unaudited interim condensed consolidated financial statements. Certain prior year amounts have been reclassified to conform to current year presentation.

Use of estimates

d. Use of estimates:

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, costs and expenses and related disclosures in the accompanying notes. Actual results and outcomes may differ from management’s estimates and assumptions due to risks and uncertainties.

Concentrations of supply risks

e. Concentrations of supply risks:

The Company depends on two contract manufacturers and several limited or single source component suppliers. Reliance on these vendors makes the Company vulnerable to possible capacity constraints and reduced control over component availability, delivery schedules, manufacturing yields, and costs.

As of September 30, 2023, and December 31, 2022, two contract manufacturers collectively accounted for 40.9% and 34.3% of the Company’s total trade payables, net, respectively.

In the second quarter of 2022, the Company announced the opening of “Sella 2”, a two gigawatt-hour (GWh) Li-Ion battery cell manufacturing facility located in South Korea. Sella 2 began producing and shipping cells at the end of 2022 and is expected to reach full manufacturing capacity in early 2024. Sella 2 is the Company's second owned manufacturing facility following the establishment of Sella 1 in 2020. Sella 1 is the Company's manufacturing facility in the North of Israel that produces power optimizers and inverters for the Company's solar activities.

New accounting standards updates

f. New accounting standards updates:

From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board ("FASB") or other standard setting bodies are adopted by the Company as of the specified effective date. The Company believes that the impact of recently issued or newly effective standards were not applicable to the Company, did not have a material impact on the condensed consolidated financial statements or are not expected to have a material impact on the condensed consolidated financial statements.

Convertible Senior Notes due 2025 [Member]
Debt Instrument [Line Items]
Debt conversion description	On September 25, 2020, the Company sold $632,500 aggregate principal amount of its 0.00% convertible senior notes due 2025 (the “Notes”). The Notes were sold pursuant to an indenture, dated September 25, 2020 (the “Indenture”), between the Company and U.S. Bank National Association, as trustee. The Notes do not bear regular interest and mature on September 15, 2025, unless earlier repurchased or converted in accordance with their terms. The Notes are general senior unsecured obligations of the Company. Holders may convert their Notes prior to the close of business on the business day immediately preceding June 15, 2025 in multiples of $1,000 principal amount, only under the following circumstances: (1) during any calendar quarter commencing after the calendar quarter ending on December 31, 2020 (and only during such calendar quarter), if the last reported sale price of the common stock for at least 20 trading days (whether or not consecutive) during the period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day; (2) during the five-business-day period after any five consecutive trading day period in which the trading price per $1,000 principal amount of the Notes for each trading day of that five consecutive trading day period was less than 98% of the product of the last reported sale price of the common stock and the conversion rate on each such trading day; or (3) upon the occurrence of specified corporate events as described in the Indenture. In addition, holders may convert their Notes, in multiples of $1,000 principal amount, at their option at any time beginning on or after June 15, 2025, and prior to the close of business on the second scheduled trading day immediately preceding the stated maturity date of the Notes, without regard to the foregoing circumstances. The initial conversion rate for the Notes was 3.5997 shares of common stock per $1,000 principal amount of Notes, which is equivalent to an initial conversion price of approximately $277.80 per share of common stock, subject to adjustment upon the occurrence of certain specified events as set forth in the Indenture.
