On July 6, 2021, the Issuer announced that its US-subsidiary Biofrontera Inc. intends to raise capital by means of an initial public offering and a stock exchange listing in the United States (“IPO”).

On September 19, 2021, the Pool Members and ABC requested to call a general shareholders meeting of the Issuer with regard to the intended IPO of Biofrontera Inc. and proposed to elect a special auditor concerning the circumstances of the IPO. On October 5, 2021, the Pool Members and ABC applied for authorization by the local court of Cologne to call a general shareholders meeting of the Issuer and also to authorize the Pool Members and ABC to publish and therewith put such proposals to the agenda of the next shareholders meeting of the Issuer. The application was rejected by the local court of Cologne on December 2, 2021.

On October 13, 2021, the Pool Members and ABC applied for calling a general meeting and an amendment to the agenda of the next shareholders meeting of the Issuer and proposed to vote against the IPO of Biofrontera Inc. and to elect a special auditor regarding the circumstances of the intended IPO.

On November 2, 2021, the Issuer announced that at the closing of the IPO, Biofrontera Inc. placed 3,600,000 Units consisting of (i) one share of Biofrontera Inc. common stock and (ii) one warrant entitling the holder to purchase one additional share of Biofrontera Inc. common stock at an exercise price of $5.00. The underwriters exercised in full their option to purchase up to an additional 540,000 warrants to cover over-allotments. Each warrant expires five years after the date of issuance. The gross proceeds to Biofrontera Inc. from the offering, before deducting the underwriting discounts and commissions and offering expenses, amounted to approximately $18,000,000.

On November 19, 2021, the Issuer announced the results of the mediation proceedings with Mr. Wilhelm K. T. Zours and DB. In the course of the mediation process, an agreement (the “Settlement Agreement”) was entered among each of the Reporting Entities, ABC, Maruho Deutschland GmbH (“Maruho”), Mr. Zours and the Issuer. Pursuant to the Settlement Agreement, (i) the Reporting Entities, ABC and Maruho agreed to vote in favor of the election of the following candidates in the upcoming Annual General Meeting: Dr. Heikki Lanckriet; Dr. Helge Lubenow; Mrs. Prof. Franca Ruhwedel; Mr. Karlheinz Schmelig; Dr. Jörgen Tielmann; and Mr. Wilhelm K. T. Zours, and (ii) the Issuer, DB, DU and ABC agreed to withdraw outstanding lawsuits. Mr. Zours declared his willingness to stand for election as Chairman of the Supervisory Board. The Settlement Agreement also provides that the authorized capital resolved by the Annual General Meeting of the Issuer on May 24, 2017 under agenda item 6, which is the subject of a pending action for rescission, and which would in any case be limited until May 23, 2022, is not to be used even after the withdrawal of the action. The Settlement Agreement does not include a review regarding the background of the IPO of Biofrontera Inc. The terms of the Settlement Agreement were subject to the condition precedent that the aforementioned candidates are elected to the Supervisory Board of the Issuer by no later than December 31, 2021.

In order to ensure that the Issuer will be able to raise further capital in the future, on November 26, 2021 DB submitted with the Issuer an amendment to the agenda of the annual general meeting to be held on December 14, 2021 with the proposals to adopt authorized capital and contingent capital. DB proposed a maximum authorized capital of 50% of the current share capital as well as a maximum contingent capital of 50% of the current share capital, both valid for five years.

On November 26, 2021, the Pool Members and ABC withdrew the proposal to elect a special auditor regarding the circumstances of the intended IPO.

On December 6, 2021, ABC merged with and into DB, with DB continuing as the surviving entity in the merger. The shares in Issuer previously held by ABC are currently held by DB.

On December 13, 2021, DB filed a new action with the local court of Cologne against the Issuer requesting that the court confirm that (i) the IPO of Biofrontera Inc. is void, (ii) the placing of shares and options to a private investor in connection with the IPO of Biofrontera Inc. is void, and (iii) the approvals of the management board and of the supervisory board with respect to (i) and (ii) are void.

On December 14, 2021, the Issuer announced that Dr. Heikki Lanckriet, Dr. Helge Lubenow, Mr. Karlheinz Schmelig, Dr. Jörgen Tielmann and Mr. Wilhelm K. T. Zours were each elected to the Supervisory Board and that Mrs. Prof. Dr. Franca Ruhwedel was re-elected to the Supervisory Board. Furthermore, at its constituting meeting on December 14, 2021, the Supervisory Board elected Wilhelm K. T. Zours as Chairman of the Supervisory Board and Dr. Jörgen Tielmann as Vice Chairman of the Supervisory Board. Furthermore, the Issuer announced that DB’s proposals concerning the maximum authorized capital and maximum contingent capital were rejected.

On December 16, 2021, DB withdrew the outstanding lawsuits as required by the Settlement Agreement.

On January 12, 2022, the Issuer published a copy of the Settlement Agreement in the Federal Gazette (Bundesanzeiger).

On February 14, 2022, the Issuer issued a press release indicating that it decided its ADSs should be delisted from the Nasdaq Capital Market (“Nasdaq”) and its reporting obligations with the Securities and Exchange Commission (the “SEC”) should be deregistered and terminated. The Issuer also announced that (i) it intends to maintain an amended ADS program on a Level I basis, which will allow investors to continue to hold their securities in the form of ADSs and trade the ADSs on the U.S. over-the-counter (OTC) market, (ii) the ADSs will automatically transition to the new ADS program in connection with the delisting and will be traded under a new ticker to be designated, (iii) the Issuer’s ordinary shares will continue to trade in the Prime Standard at the Deutsche Börse under the symbol B8F, (iv) holders of ADSs may choose to exchange their ADSs to holding ordinary shares listed on the Deutsche Börse, and (v) the Issuer plans to submit a Form 25 relating to its ADSs on Nasdaq to the SEC on or about February 24, 2022 to initiate the delisting and expects the delisting to be become effective not less than ten days later. If the Issuer ceases to have any equity securities registered under Section 12 of the Securities Exchange Act of 1934, as amended, the Reporting Persons will no longer have any obligation to file (and will cease filing) statements of beneficial ownership on Schedule 13D with respect to such equity securities.

On February 22, 2022, the Issuer issued a press release announcing that Prof. Dr. Franca Ruhwedel resigned from her position as a member of the supervisory board with immediate effect for good cause.

Except as set forth above, the Reporting Persons have no current plans or proposals with respect to (i) the acquisition by any person of additional securities of the Issuer, or the disposition of securities of the Issuer; (ii) any extraordinary corporate transaction, such as a merger, reorganization, or liquidation, involving the Issuer or any of its subsidiaries, (iii) a sale or transfer of a material amount of assets of the Issuer or any of its subsidiaries, (iv) any change in the present board of directors or management of the Issuer, including any plans or proposals to change the number or term of directors or to fill any existing vacancies on the board; (v) any material change in the present capitalization or dividend policy of the Issuer; (vi) any other material change in the Issuer’s business or corporate structure, (vii) changes to the Issuer’s organizational documents or instruments corresponding thereto or other actions which may impede the acquisition of control of the Issuer by any person; (viii) causing a class of securities of the Issuer to be delisted from a national securities exchange or to cease to be authorized to be quoted in an inter-dealer quotation system of a registered national securities association; (ix) a class of equity securities of the Issuer becoming eligible for termination of registration pursuant to section 12(g)(4) of the Securities Exchange Act of 1934, as amended; or (x) any action similar to any of the foregoing.
