As of December 31, 2020, AudioCodes Ltd. (the “Company”) had the following class of securities registered under Section 12(b) of the Securities Exchange Act of 1934, as amended: ordinary shares, nominal value NIS 0.01 per share. The Company’s ordinary shares are listed on the Nasdaq Global Select Market and on the Tel-Aviv Stock Exchange under the trading symbol “AUDC”.

DESCRIPTION OF SHARE CAPITAL

This description summarizes relevant provisions of the Israeli Companies Law, 5759-1999, or the Companies Law. The following summary does not purport to be complete and is subject to, and is qualified in its entirety by reference to, the applicable provisions of the Companies Law and the Company’s articles of association, a copy of which is incorporated by reference as an exhibit to the Annual Report on Form 20-F of which this Exhibit 2.1 is a part. The Company encourages you to read its articles of association and the applicable provisions of the Companies Law for additional information.

Authorized Share Capital

Our authorized share capital consists of NIS 1,025,000 divided into 100,000,000 ordinary shares, nominal value NIS 0.01 per share, and 2,500,000 preferred shares, nominal value NIS 0.01 per share. As of April 20, 2021, we had 32,770,828 ordinary shares outstanding (which does not include 29,921,614 treasury shares) and no preferred shares outstanding.

Borrowing Powers

The board of directors has the power to cause us to borrow money and to secure the payment of borrowed money. The board of directors specifically has the power to issue bonds or debentures, and to impose mortgages or other security interests on all or any part of our property.

Amendment of Articles of Association

In general, shareholders may amend our articles of association by a resolution adopted at a shareholders meeting by the holders of 50% of the voting power represented at the meeting in person or by proxy and voting thereon. The amendment of certain provisions of our articles of association requires an increased voting threshold. For example, the approval of amendments to the provisions concerning business combinations with certain shareholders requires the approval of holders of 85% of our outstanding voting shares. Additionally, amendments to the provisions concerning (i) the procedure according to which shareholders may propose items to include in the agenda of a general meeting of the shareholders and (ii) the role and composition of the board of directors, including the method of appointment of its members, require the approval sixty-six and two-thirds percent (66 2/3%) of the voting power represented at the meeting in person or by proxy and voting thereon.

Qualification of Directors

No person shall be disqualified to serve as a director by reason of his not holding AudioCodes shares or by reason of his having served as a director in the past.

Dividends

Under the Israeli Companies Law, we may pay dividends only out of our profits as determined for statutory purposes, unless court approval is granted for the payment of dividends despite the lack of statutory profits. (There is a unified statutory test for the payment of dividends and a company’s repurchase of its outstanding shares.) In 2020 and again in early 2021, we received court approval to pay dividends (and repurchase our shares) up to certain ceilings, despite the lack of statutory profits. The current approval is valid until July 19, 2021. We may seek further approvals to repurchase our shares and to continue to pay dividends. The amount of any dividend to be distributed among shareholders is based on the nominal value of their shares.

Voting Rights and Powers

Unless any shares have special rights as to voting, every shareholder has one vote for each share held of record.

Under our articles of association, we may issue preferred shares from time to time, in one or more series. However, in connection with our listing on The Tel-Aviv Stock Exchange in 2001, we agreed that for such time as our ordinary shares are traded on The Tel-Aviv Stock Exchange, we will not issue any of the 2,500,000 preferred shares, nominal value NIS 0.01, authorized in our articles of association. Notwithstanding the foregoing, we may issue preferred shares if the preference of those shares is limited to a preference in the distribution of dividends and such preferred shares have no voting rights.

Business Combinations

Our articles of association impose restrictions on our ability to engage in any merger, asset or share sale or other similar transaction with a shareholder holding 15% or more of our voting shares.

Winding Up

Upon our liquidation, our assets available for distribution to shareholders will be distributed to them in proportion to the nominal value of their shares.

Redeemable Shares

Subject to our undertaking to the Tel-Aviv Stock Exchange as described above, we may issue and redeem redeemable shares.

Modification of Rights

Subject to the provisions of our articles of association, we may, from time to time, by a resolution approved by the holders of a simple majority of the voting power represented at the meeting in person or by proxy and voting thereon, provide for shares with such preference rights, deferred rights or conversion rights, or any other special rights or limitations as may be stipulated in such resolution.

If at any time our share capital is divided into different classes of shares, we may modify or abrogate the rights attached to any class, unless otherwise provided by the articles of association, by a resolution approved by the holders of a simple majority of the voting power represented at the meeting in person or by proxy and voting thereon, subject to the consent in writing of the holders of a simple majority of the issued shares of that class (unless otherwise provided by law or by the terms of issue of the shares of that class).

The provisions of our articles of association relating to general meetings also apply, mutatis

mutandis, to any separate general meeting of the holders of the shares of a particular class.

The creation or issuance of shares of any class, including a new class, shall not be deemed to alter the rights and privileges attached to previously issued shares of that class or of any other class (unless otherwise provided by our articles of association, including the terms of issue of the shares of any class).

Shareholder Meetings

An annual meeting of shareholders is to be held once a year, within 15 months after the previous annual meeting. The annual meeting may be held in Israel or outside of Israel, as determined by the board of directors.

The board of directors may, whenever it thinks fit, convene a special shareholders meeting. The board of directors must convene a special shareholders meeting at the request of:

at least two directors;

at least one-quarter of the directors in office; or

one or more shareholders who hold at least 5% of the outstanding share capital and at least 1% of the voting rights, or one or more shareholders who hold at least 5% of the outstanding voting rights.

A special shareholders meeting may be held in Israel or outside of Israel, as determined by the board of directors.

Notice of General Meetings; Omission to Give Notice

The provisions of the Companies Law and the related regulations override the provisions of our articles of association, and provide for notice of a meeting of shareholders to be sent to each registered shareholder at least 21 days or 35 days in advance of the meeting, depending on the items included in the meeting agenda. Notice of a meeting of shareholders must also be published in two Israeli newspapers or on our website.

Notice of a meeting of shareholders must specify the type of meeting, the place and time of the meeting, the agenda, a summary of the proposed resolutions, the majority required to adopt the proposed resolutions, and the record date for the meeting. The notice must also include the address and telephone number of our registered office, and a list of times at which the full text of the proposed resolutions may be examined at the registered office.

The accidental omission to give notice of a meeting to any shareholder, or the non-receipt of notice sent to such shareholder, does not invalidate the proceedings at the meeting.

Limitations on Foreign Shareholders to Hold or Exercise Voting Rights

There are no limitations on foreign shareholders in our articles of association. Israeli law restricts the ability of citizens of countries that are in a state of war with Israel to hold shares of Israeli companies.

Fiduciary Duties; Approval of Transactions under Israeli Law

Fiduciary duties. The Companies Law codifies the fiduciary duties that office holders, which under the Companies Law includes our directors and executive officers, owe to a company. An office holder’s fiduciary duties consist of a duty of loyalty and a duty of care.

The duty of loyalty requires an office holder to act in good faith and for the benefit of the company, including to avoid any conflict of interest between the office holder’s position in the company and personal affairs, and prohibits any competition with the company or the exploitation of any business opportunity of the company in order to receive a personal advantage for himself or herself or for others. This duty also requires an office holder to reveal to the company any information or documents relating to the company’s

affairs that the office holder has received due to his or her position as an office holder. A company may approve any of the acts mentioned above provided that all the following conditions apply: the office holder acted in good faith and neither the act nor the approval of the act prejudices the good of the company and, the office holder disclosed the essence of his personal interest in the act, including any substantial fact or document, a reasonable time before the date for discussion of the approval. A director is required to exercise independent discretion in fulfilling his or her duties and may not be party to a voting agreement with respect to his or her vote as a director. A violation of these requirements is deemed a breach of the director’s duty of loyalty.

The duty of care requires an office holder to act with a level of care that a reasonable office holder in the same position would employ under the same circumstances. This includes the duty to use reasonable means to obtain information regarding the advisability of a given action submitted for his or her approval or performed by virtue of his or her position and all other relevant information material to these actions.

Disclosure of personal interest. The Companies Law requires that an office holder promptly disclose to the company any personal interest that he or she may have and all related material information or documents known to him or her, in connection with any existing or proposed transaction by the company. “Personal interest,” as defined by the Companies Law, includes a personal interest of any person in an act or transaction of the company, including a personal interest of his relative or of a corporation in which that person or a relative of that person is a 5% or greater shareholder, a holder of 5% or more of the voting rights, a director or general manager, or in which he or she has the right to appoint at least one director or the general manager, and includes shares for which the person has the right to vote pursuant to a power-of-attorney. “Personal interest” does not apply to a personal interest stemming merely from holding shares in the company.

The office holder must make the disclosure of his personal interest no later than the first meeting of the company’s board of directors that discusses the particular transaction. This duty does not apply to the personal interest of a relative of the office holder in a transaction unless it is an “extraordinary transaction.” The Companies Law defines an “extraordinary transaction” as a transaction that is not in the ordinary course of business, not on market terms or that is likely to have a material impact on the company’s profitability, assets or liabilities.

Approvals. The Companies Law provides that a transaction with an office holder or a transaction in which an office holder has a personal interest requires board approval, unless the transaction is an extraordinary transaction or the articles of association provide otherwise. Our articles of association do not provide otherwise. The transaction may be approved only if it is in our best interest. If the transaction is an extraordinary transaction, then the approvals of the company’s audit committee and the board of directors are required. If the transaction concerns exculpation, indemnification, insurance or compensation of an office holder, then the approvals of the company’s compensation committee and the board of directors are required, except if the compensation arrangement is an immaterial amendment to an existing compensation arrangement of an officer who is not a director, in which case the approval of the compensation committee is sufficient. Exculpation, indemnification, insurance or compensation of a director or the Chief Executive Officer also requires shareholder approval.

A person who has a personal interest in a matter that is considered at a meeting of the board of directors or the audit committee generally may not attend that meeting or vote on that matter, unless a majority of the board of directors or the audit committee has a personal interest in the matter or if such person is invited by the chairman of the board of directors or audit committee, as applicable, to present the matter being considered. If a majority of the board of directors or the audit committee has a personal interest in the transaction, shareholder approval also would be required.

Shareholders

The Companies Law imposes on a controlling shareholder of a public company the same disclosure requirements described above as it imposes on an office holder. For this purpose, a “controlling

shareholder” is any shareholder who has the ability to direct the company’s actions, including any shareholder holding 25% or more of the voting rights if no other shareholder owns more than 50% of the voting rights in the company. Two or more shareholders with a personal interest in the approval of the same transaction are deemed to be one shareholder.

Approval of the audit committee, the board of directors and our shareholders, in that order, is required for extraordinary transactions, including a private placement, with a controlling shareholder or in which a controlling shareholder has a personal interest.

Approval of the compensation committee, the board of directors and our shareholders, in that order, is required for the terms of compensation or employment of a controlling shareholder or his or her relative, as an officer holder or employee of our company or as a service provider to the company, including through a company controlled by a controlling shareholder.

Shareholder approval must include the majority of shares voted at the meeting. In addition to the majority vote, the shareholder approval must satisfy either of two additional tests:

the majority includes at least a majority of the shares voted by shareholders who have no personal interest in the transaction; or

the total number of shares held by disinterested shareholders that voted against the approval of the transaction does not exceed 2% of the aggregate voting rights of our company.

Generally, the approval of such a transaction may not extend for more than three years, except that in the case of an extraordinary transaction, including a private placement, with a controlling shareholder or in which a controlling shareholder has a personal interest that does not concern compensation for employment or service, the transaction may be approved for a longer period if the audit committee determines that the approval of the transaction for a period longer than three years is reasonable under the circumstances.

Duties of Shareholders

Under the Israeli Companies Law, a shareholder also has a duty to act in good faith towards the company and other shareholders and refrain from abusing his or her power in the company, including, among other things, voting in the general meeting of shareholders on the following matters:

any amendment to the articles of association;

an increase of the company’s authorized share capital;

a merger; or

·approval of related party transactions that require shareholder approval.

In addition, any controlling shareholder, any shareholder who can determine the outcome of a shareholder vote and any shareholder who, under the company’s articles of association, can appoint or prevent the appointment of an office holder, is under a duty to act with fairness towards the company. The Israeli Companies Law also provides that a breach of the duty of fairness will be governed by the laws governing breach of contract; however, the Israeli Companies Law does not describe the substance of this duty.

Anti-Takeover Provisions Under Israeli Law

The Companies Law provides that an acquisition of shares in a public company must be made by means of a tender offer if as a result of the acquisition the purchaser would hold 25% or more of the voting rights in the company, unless there is already another shareholder of the company with 25% or more of the voting rights. Similarly, the Companies Law provides that an acquisition of shares in a public company must be made by means of a tender offer if as a result of the acquisition the purchaser would hold more than 45% of the voting rights in the company, unless there is a shareholder with more than 45% of the

voting rights in the company.

The Companies Law requires the parties to a proposed merger to file a merger proposal with the Israeli Registrar of Companies, specifying certain terms of the transaction. Each merging company’s board of directors and shareholders must approve the merger. Shares in one of the merging companies held by the other merging company or certain of its affiliates are disenfranchised for purposes of voting on the merger. A merging company must inform its creditors of the proposed merger. Any creditor of a party to the merger may seek a court order blocking the merger, if there is a reasonable concern that the surviving company will not be able to satisfy all of the obligations of the parties to the merger. Moreover, a merger may not be completed until at least 50 days have passed from the time that the merger proposal was filed with the Israeli Registrar of Companies and at least 30 days have passed from the approval of the shareholders of each of the merging companies.

Finally, in general, Israeli tax law treats stock-for-stock acquisitions less favorably than does U.S. tax law. Israeli tax law provides for tax deferral in specified acquisitions, including transactions where the consideration for the sale of shares is the receipt of shares of the acquiring company. Nevertheless, Israeli tax law may subject a shareholder who exchanges his ordinary shares for shares in a foreign corporation to immediate taxation or to taxation before his investment in the foreign corporation becomes liquid, although in the case of shares of a foreign corporation that are traded on a stock exchange, the tax may be postponed subject to certain conditions.
