Addex Therapeutics Annual Report 2022 

Letter to Shareholders 

Dear Shareholders,  

2022 has been a very challenging year with the inconclusive data from our blepharospasm clinical study followed by the termination 
of dipraglurant’s development in PD-LID due to a slow recruitment rate attributed to COVID-19 pandemic related constraints. We 
have substantially completed our evaluation of the future development of dipraglurant and have identified stroke recovery and pain 
as  interesting  areas  for  future  development  in  addition  to  PD-LID.  We  are  currently  pursuing  collaborative  arrangements  prior  to 
restarting development. 

On a more positive note, our partner Janssen Pharmaceuticals Inc., a Johnson and Johnson company, made excellent progress in 
advancing the ADX71149 phase 2a proof of concept clinical study in epilepsy patients with the enrollment of 60 patients in cohort 1 
and the start of enrollment of patients in cohort 2. An independent interim review committee (IRC) has been constituted by Janssen 
to review the data and make a recommendation on the future direction of the study which we expect to report early in the second 
quarter of 2023. 

In addition, we made substantial progress in our collaboration with our partner, Indivior, in advancing our gamma-aminobutyric acid 
subtype  B  receptor  (“GABA  B”)  positive  allosteric  modulators  (“PAMs”)  program  towards selection  of  development  candidates  for 
substance use disorder, CMT1A, chronic cough and pain. During 2022, we extended our research collaboration with Indivior and they 
agreed  additional  research  funding  of  CHF1.8  million,  bringing  total  research  funding  since  2018  to  more  than  CHF13.8  million, 
demonstrating their strong commitment to our partnership. 

Furthermore, we made excellent progress in our unpartnered preclinical portfolio: 

Our metabotropic glutamate receptor subtype 7 (“mGlu7”) negative allosteric modulators (“NAM”) program for stress related disorders, 
including post-traumatic stress disorder, made significant progress in 2022. As result we have selected a drug candidate to enter 
investigational new drug (“IND”) enabling studies and have multiple novel back up series of compounds in clinical candidate selection 
phase. 

Our metabotropic glutamate receptor subtype 2 (“mGlu2”) NAM program for mild neurocognitive disorders has made solid progress 
in  2022  with  multiple novel  lead  series  of compounds progressing in  lead optimization  and  one  series  entering  clinical  candidate 
selection. 

Our muscarinic acetylcholine receptor subtype 4 (“M4”) PAM program for the treatment of schizophrenia and other psychoses has 
rapidly advanced multiple differentiated novel chemical series into late lead optimization. 

Due to the challenging financing environment, we continue to pursue discussions with potential partners across our portfolio, focus 
on cost control and making selective investments in areas of our portfolio where we believe we can bring the most value to support 
our discussions with potential partners. We strengthened our balance sheet in July 2022 with a small offering raising gross proceeds 
of $4.2 million from the sale of new shares primarily in the form of American Depository Shares on the Nasdaq Stock Market. 

We  have  made  significant  progress  in a  difficult year  and  would  like  to  acknowledge and thank  our  employees  and collaboration 
partners for their dedication, loyalty and perseverance. We would also like to thank our shareholders for their valued support.

Addex Therapeutics Annual Report 2022│Financial Review 

Financial Review  

The following review and discussion of the financial results for 2022 should be read in conjunction with the consolidated financial 
statements and related notes, which have been prepared in accordance with International Financial Reporting Standards and are 
presented in this Annual Report. 

We are a clinical development-stage biopharmaceutical company focused on building a sustainable pharmaceutical business around 
our expertise in the discovery and development of oral small molecule allosteric modulators of G-protein coupled receptors. As a 
result, commercialization is currently limited to licensing, and research and development services related to selected discovery and 
development stage programs. 

During 2022, our financial results are driven primarily by activities related to the development of dipraglurant for Parkinson’s disease 
levodopa-induced dyskinesia (“PD-LID”) and blepharospasm, as well as discovery activities related to our gamma-aminobutyric acid 
subtype B receptor (“GABAB”) positive allosteric modulators (“PAMs”) partnership with Indivior PLC (“Indivior”), M4 PAM program 
and to a lesser extent our metabotropic glutamate subtype 7 receptor (“mGlu7”) negative allosteric modulator (“NAM”) and mGlu2 
NAM  programs.  In  addition,  we  were  engaged  in  a  number  of  business  development  and  financing  activities  related  to  securing 
resources to advance our portfolio, including entering into collaborations with patient advocacy groups, academic institutions and 
governmental  organizations  to  characterize  our  portfolio  of  drug  candidates  and  access  expertise  to  complement  our  internal 
resources. At December 31, 2022, our headcount was 24 full time equivalents (FTEs) compared to 26 FTEs at December 31, 2021. 
Our average headcount was stable at 25 in 2022 and 2021. In addition to our headcount, we engaged a number of consultants and 
service providers to complement our internal resources. 

Research and development expenditure increased to CHF 14.6 million and general and administrative expenses increased to CHF 
7.3 million. CHF 1.4 million has been recognized as income in the year and our net loss increased to CHF 20.8 million. We ended the 
year with a cash position of CHF 7.0 million.

Income 
Income decreased by CHF 1.7 million in 2022 compared to 2021 primarily due to reduced research funding from Indivior which is 
recognized in income as related costs are incurred.  

Research and development expenses 
R&D  expenses  increased  by  CHF  1.8  million  to  CHF  14.6  million  in  2022,  compared  to  CHF  12.8  million  in  2021.  The  increase 
primarily relates to outsourced R&D costs for CHF 1.0 million including dipraglurant clinical development activities for CHF 0.4 million 
and discovery activities for CHF 0.6 million, as well as higher share-based compensation costs for CHF 0.6 million. R&D expenses 
consist  primarily  of  costs  associated  with  research,  preclinical  and  clinical  testing  and  related  staff  costs.  They  also  include 
depreciation of laboratory equipment, costs of materials used in research, costs associated with renting and operating facilities and 
equipment, as well as fees paid to consultants, patent costs, other outside service fees and overhead costs. These expenses include 
costs for proprietary and third-party R&D.  

General and administrative expenses 
G&A expenses increased by CHF 1.5 million to CHF 7.3 million in 2022, compared to CHF 5.8 million in 2021, primarily due to higher 
share-based compensation costs.    

Finance Result, net 
Finance result net decreased by CHF 0.4 million in 2022 compared to 2021 mainly due to currency exchange differences on U.S 
dollar cash deposits following the strengthening of the Swiss franc.

Addex Therapeutics Annual Report 2022│Financial Review 

Net loss for the year 
The net loss for the 2022 financial year was CHF 20.8 million compared to CHF 15.4 million for 2021. The increase in the net loss of 
CHF 5.4 million is primarily due to increased share-based compensation costs of CHF 2.5 million and a CHF 1.7 million reduction in 
revenue. Basic and diluted loss per share increased to CHF 0.46 for 2022, compared to CHF 0.45 for 2021 due to an increase in the 
loss offset by an increase in the weighted average number of shares issued.  

Balance sheet & cash flows 

Cash and cash equivalents decreased by CHF 13.5 million to CHF 7.0 million at December 31, 2022, compared to CHF 20.5 million 
at December 31, 2021. During the same period, total shareholders’ equity decreased by CHF 12.0 million and amounted to CHF 4.9 
million at December 31, 2022 compared to CHF 16.9 million at December 31, 2021. Decreases in both cash and cash equivalents 
and  total  shareholders’  equity  are  primarily  due  to  the  net  loss  of  CHF  20.8  million  adjusted  for  CHF  3.7  million  of  share-based 
compensation expense, partially offset by the net proceeds of CHF 3.7 million from the offering executed on July 22, 2022.  

Post balance sheet event 

The  Group  sold  3,742,506  treasury  shares  for  a  gross  amount  of  CHF  1.2  million  under the  sale  agency  agreement  with  Kepler 
Cheuvreux, between the closing date and the approval of these consolidated financial statements by the board of directors.  

Shares and shareholders’ information 

At December 31, 2022, the Company had 115,348,311 (2021: 49,272,952) issued shares and a free float of approximately 58.25%. 
Of  the  issued  shares  at  December  31,  2022,  38,214,291  shares  (at  December  31, 2021:  11,374,803  shares)  are  held  by  Addex 
Pharma SA and recorded as treasury shares. The closing share price was CHF 0.10 at December 31, 2022 compared to CHF 1.04 
at December 31, 2021 and the market capitalization was CHF 11.7 million compared to CHF 51.2 million, respectively. 

2023 Outlook 

Following the completion of enrollment of patients in part 1 of the ADX71149 phase 2a epilepsy clinical study by our partner Janssen 
Pharmaceuticals Inc., we expect to report the outcome of the independent interim review committee (IRC) review of the data and  
next steps at the beginning of the second quarter of 2023. We are also continuing discussions with potential strategic partners to 
reinitiate Phase 2 development of dipraglurant in PD-LID or alternative indications, including stroke recovery, SUD and pain. 

Furthermore, we expect to advance our mGlu7NAM discovery program into IND enabling studies in 2023, prepare our GABAB PAM 
program under our partnership with Indivior for IND enabling studies in 2024 and progress our mGlu2 NAM and M4 PAM programs 
in  clinical  candidate  selection  phase.  We  will  continue  to  invest  in  our  allosteric  modulator  technology  platform  and  pursue 
collaborations  with  industry,  patient  advocacy  groups,  academic  institutions  and  governmental  organizations  to  drive  forward  our 
portfolio of allosteric modulator drug candidates and secure further financial resources to advance their development and strengthen 
our balance sheet,

On October 31, 2022, the Company increased its share capital from CHF 652,730 to CHF 979,094 through the issuance of 32,636,476 
new registered shares at nominal value of CHF 0.01 each out of the authorized capital. 

On May 9, 2022, the shareholders (i) increased the authorized capital from CHF 8,636,476 to CHF 32,636,476 and extended its term 
to May 9, 2024 and (ii) increased the conditional capital from CHF 24,636,476 to CHF 32,636,476. On the same date, the shareholders 
approved the reduction of the nominal value from CHF 1 to CHF 0.01 of all 65,272,952 issued shares, and of all shares issuable from 
the authorized capital and conditional capital. The approved reduction was registered by the Geneva’s commercial registry on July 
19, 2022 and published on July 22, 2022, after the expiration of a period of two months from the publication in the Swiss Gazette of 
Commerce of three calls to creditors. The Company's share capital was thus reduced by a total amount of CHF 64,602,222.48 from 
CHF  65,272,952  to  CHF  652,729.52,  and  its  authorized  capital  and  conditional  capital  were  each  reduced  by  a  total  amount  of  
CHF 32,310,111.24 from CHF 32,636,476 to CHF 326,634.76. The Company's total number of issued shares (i.e. 65,272,952) as 
well as its total number of issuable shares out of the authorized capital and conditional capital were not affected by the reduction. The

amount corresponding to the nominal reduction of the Company's issued capital was allocated to capital contributions reserves and 
there was no distribution to shareholders. 

On February 2, 2022, the Company increased its share capital from CHF 49,272,952 to CHF 65,272,952 through the issuance of 
16,000,000 new registered shares at nominal value of CHF 1 each out of the authorized capital.  

For further information on changes in capital including changes in reserves, refer to the consolidated statements of changes in equity 
as well as note 12 of the consolidated financial statements included in this Annual Report. 

2.4.  Shares and participation certificates 

Addex has one class of shares, i.e. registered shares with a nominal value of CHF 0.01 per share. Each share is fully paid up and 
carries one vote and equal dividend rights, with no privileges. The Company has no participation certificates (bons de participation / 
Partizipationsscheine).  

2.5.  Dividend-right certificates 

Equity sharing certificates are available for granting to employees and/or directors and/or consultants of the Company or any Group 
company under the Group’s equity incentive plan. Equity sharing certificates do not form part of the share capital, have no nominal 
value, and do not grant any right to vote nor to attend meetings of shareholders. The Company has 1,700 issued equity sharing 
certificates (bons de jouissance/Genussscheine). Each equity sharing certificate grants the right to subscribe for 1,000 shares of the 
Company and a right to liquidation proceeds of the Company calculated in accordance with article 34 of the Articles.  

The Company’s shares and equity sharing certificates are not certificated. Shareholders and equity sharing certificate holders are not 
entitled to request printing and delivery of certificates, however, any shareholder or equity sharing certificate holder may at any time 
request the Company to issue a confirmation of their holdings. 

2.6.  Limitations on transferability of shares and nominee registration 

A  transfer  of  uncertified shares  is  affected  by  a corresponding  entry  in  the  books  of  a  bank  or  depository  institution  following  an 
assignment in writing by the selling shareholder and notification of such assignment to Addex by the bank or the depository institution. 
If following a transfer of shares a shareholder wishes to vote at or participate in a shareholders’ meeting, such shareholder must file 
a share registration form in order to be registered in the share register with voting rights. Failing such registration, a shareholder may 
not vote at or participate in a shareholders meeting. The shares in the form of American Depository Shares or ADSs are held by 
Citibank acting as depositary and voted at the shareholders’ meeting according to the instructions received from the ADS holders.  

A purchaser of shares will be recorded in Addex’ share register as a shareholder with voting rights if the purchaser discloses its name, 
citizenship or registered office and address and declares that it has acquired the shares in its own name and for its own account.  

Article 5 of the Articles provides that a person or entity not explicitly stating in its registration request that it will hold the shares for its 
own account (Nominee) may be entered as a shareholder in the share register with voting rights for shares up to a maximum of 5% 
of the share capital as set forth in the commercial register. Shares held by a Nominee that exceed this limit are only registered in the 
share register with voting rights if such Nominee discloses the name, address and shareholding of any person or legal entity for whose 
account it is holding 1% or more of the share capital as set forth in the commercial register. The limit of 1% shall apply correspondingly 
to  Nominees  who  are  related  to  one  another  through  capital  ownership  or  voting  rights  or  have  a  common  management  or  are 
otherwise interrelated. A share being indivisible, hence only one representative of each share will be recognized. Furthermore, shares 
may only be pledged in favor of the bank that administers the bank entries of such shares for the account of the pledging shareholders. 
If the registration of shareholdings with voting rights was effected based on false information, the Board may cancel such registration 
with retroactive effect. 

There are no further rules in the Articles for granting exceptions and no exceptions were granted in 2022. The Articles do not contain 
any provisions on the procedure and conditions for cancelling privileges and limitations on transferability. 

2.7.  Convertible bonds and options 

As of December 31, 2022, the Company has no convertible or exchangeable bonds or loans outstanding. As of December 31, 2022, 
the  Company  has  a  total of 30,874,670  options outstanding,  which primarily include  (i)  777,000  options  granted  according  to  the 
Employee Share Option Plan (ESOP), (ii) 5,866,898 warrants granted to various investors on March 29, 2018, and (iii) 9,230,772 and 
15,000,000 warrants granted to one investor, respectively on December 21, 2021 and July 26, 2022. The ESOP options outstanding 
were granted to employees or consultants of the Group. They vest over a four-year period, have a ten-year expiration term and a 
strike price between CHF 0.13 to CHF 3.00. 

In connection with the capital increase of March 28, 2018, each investor was granted 0.45 warrants for each new share subscribed. 
Upon exercise (which may occur without any specific conditions), each warrant entitles the investor to subscribe one registered share 
at a price of CHF 3.43 during a seven-year period.

applicable legal provisions. 

6.3.  Convocation of the general meeting of shareholders 

The shareholders’ meeting is the supreme body of the Company and under Swiss law, the ordinary shareholders’ meeting takes place 
annually  within  six  months  after  the  close  of  the  business  year.  Shareholders’  meetings  may  be  convened  by  the  Board  or,  if

and the proposals. 

6.4.  Inclusion of items on the agenda 

Shareholders representing shares with a nominal value of at least CHF 1,000,000 or 10% of the share capital have the right to request 
in writing that an item be included on the agenda of the next shareholders’ meeting, setting forth the item and the proposal. A request

shareholders’ meeting will be determined and communicated prior to the end of April 2023. Addex has not enacted any rules on the 
granting of exceptions in relation to these deadlines. No exceptions were granted in 2022, and the Board does not anticipate granting 
any exceptions related to the shareholders’ meeting to be held in 2023. For further information on registration in the share register, 
please refer to section “Limitations on transferability of shares and nominee registration” on page 9. 

7.  Changes of control and defense measures 

7.1.  Duty to make an offer 

Swiss law provides for the possibility to have the Articles contain a provision which would eliminate the obligation of an acquirer of 
shares, exceeding the threshold of 33 1/3% of the voting rights (whether exercisable or not), to proceed with a public tender offer to 
acquire 100% of the listed equity securities of the Company (opting-out provision pursuant to article 125 para. 3 FMIA or which would 
increase such threshold to 49% of the voting rights (opting-up provision pursuant to article 135 para. 1 FMIA).  

Page 17 of 70 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Addex Therapeutics Annual Report 2022│Corporate Governance Report 

On March 16, 2018, the EGM resolved a selective opting-out limited to a 5-year period of the mandatory offer rules of article 135 FMIA 
based on article 125 para. 3 FMIA by adopting a new article 39 of the Articles (the "Opting-out") in order to facilitate the financing of 
the Company by two lead investors, i.e. Growth Equity Opportunities Fund IV, LLC and New Leaf Biopharma Opportunities I, L.P., 
and  to  provide  legal  certainty  in  connection  with  the  possible  legal  consequences  under  Swiss  takeover  law  of  these  investors' 
acquisition of newly issued registered shares of the Company for an amount of around CHF 20,000,000 in March 2018. As a result 
of the Opting-out, neither Growth Equity Opportunities Fund IV, LLC. or New Leaf Biopharma Opportunities I, L.P., nor their respective 
affiliates would have a duty to make a mandatory offer for a period until March 21, 2023 in case any of them would acquire (either 
alone  or  acting  in  concert  pursuant  to  article  135  FMIA)  33 1/3%  or  more  of  the  outstanding  voting  rights  of  the  Company.  The 
Company's shareholders would be deprived of their right to tender their shares in a mandatory offer triggered by a change of control 
over the Company caused by Growth Equity Opportunities Fund IV, LLC and/or New Leaf Biopharma Opportunities I, L.P. and/or 
their respective affiliates until March 21, 2023 pursuant to article 135 FMIA. The extension of the opting out will be discussed during 
the next annual general assembly that is planned to be held the week of May 22, 2023.   

On August 18, 2022, the Swiss Takeover Board granted, subject to certain conditions, an exemption to Addex Pharma SA from the 
obligation to make an offer in relation to the acquisition of shares in Addex. After such acquisition, which occurred on October 31, 
2022, Addex Pharma SA temporarily exceeded the shareholding threshold of 33 1/3 % of the voting rights in Addex. On December 
19, 2022, Addex Pharma reduced its shareholding in Addex below the threshold of 33 1/3% of the voting rights, thus complying with 
all conditions of the exemption.  

7.2.  Clauses on changes of control 

Addex’ equity sharing certificate incentive plan, share option plan and staff retention deferred strike price payment plan contain a 
provision in respect of changes of Addex shareholder base. In the event of a change of control over Addex (defined as a change of 
control event triggering a mandatory public tender offer according to applicable stock exchange rules) all outstanding unvested share 
options and subscription rights attached to equity sharing certificates, vest, and become exercisable with their remaining term being 
reduced proportionally, and deferred strike price payment obligations and sales restrictions associated with the staff retention deferred 
strike price payment plan are waived. 

8.  Auditors 

8.1.  Duration of the mandate and term of office of the lead auditor 

Pursuant to article 23 of the Articles and the Organization Rules, the auditor shall be elected every year and may be re-elected. The 
statutory and group auditors of Addex Therapeutics is BDO AG, Switzerland since their election during the Annual General Meeting 
held on June 9, 2020. Mr. Christoph Tschumi acts as lead auditor of Addex since 2020.  

8.2.  Auditing fees 

In 2022, BDO AG charged the Group audit fees in the amount of CHF 260,000.   

8.3.  Additional fees 

In 2022, BDO AG charged the Group additional fees of CHF 34,141 for services relating to operations on the capital and Nasdaq 
Stock Market related filings. 

8.4.  Information instruments pertaining to the external audit 

The Audit Committee as a committee of the Board reviews and evaluates the performance and independence of the auditor at least 
once a year. Based on its review, the Audit Committee recommends to the Board, which external auditor should be proposed for 
election at the general meeting of shareholders. The decision regarding the general meeting agenda is then taken by the Board. 
When evaluating the performance and independence of the auditor, the Audit Committee puts special emphasis on criteria such as 
global network of the audit firm, professional competence of the lead audit team, understanding of Addex' specific business risks, 
personal independence of the lead auditor and independence of the audit firm as a company and coordination of the auditor with the 
Audit Committee. 

The Audit Committee determines the scope of the external audit and the relevant methodology to be applied to the external audit with 
the auditors and discusses the results of the respective audits with the auditor. Representatives of the auditor are regularly invited to 
meetings of the Audit Committee, to attend during those agenda points dealing with an accounting, financial reporting or auditing 
matters. 

The Audit Committee assumes the task of supervising the auditors. The Audit Committee meets with external auditor at least once a 
year to discuss the scope and the results of the audit and to assess the quality of their service. The auditor prepares a Board Report 
addressed to the Chairman of the Board two times per year, informing them of their audit plan for the year under review followed by 
a report detailing the result of their annual audit. 

In 2022, the Chairman of the Board or Audit Committee met with the auditors five times to discuss the financial situation of the Group, 
the scope and the results of their 2021 year-end audit and their review of the interim reports relating to the published quarterly reports.

Addex' Articles, Organization Rules and policies provided the basis for the principles of compensation. 

Review and approval process 

Subject to the powers of the general meeting of shareholders, the Board of Directors determines the compensation of its members 
and  of  the  Executive  Management  in  accordance  with  the  Company’s  Compensation  Policy,  on  the  recommendation  of  the 
Compensation Committee. The Compensation Committee is composed of two members of the Board of Directors who have been 
individually elected by the general meeting of shareholders, for a term of one year, until the end of the next annual general meeting. 
The Board of Directors elects the chairman of the Compensation Committee from the members of the Compensation Committee. 
Members of the compensation Committee are eligible for re-election indefinitely. 

The Compensation Committee supports the Board of Directors in establishing and reviewing the Company’s compensation strategy, 
guidelines and the performance targets. The Compensation Committee may also submit proposals to the Board of Directors in other 
compensation-related issues. For a more detailed description of the Compensation Committee, please refer to section 3.5.2 of the 
Corporate Governance Report on page 12. 

The Compensation Committee meets as often as necessary to fulfil its role, and generally at least once a year. The Board of Directors 
generally  resolves on  the  recommendations  of  the  Compensation  Committee  during  the  meeting of  the  Board  of  Directors  which 
immediately follows the meeting of the Compensation Committee during which a recommendation was made. 

As a principle, the Chief Executive Officer (“CEO”) attends the meetings of the compensation Committee and, provided he is also a 
Board Member, attends and votes during the meetings of the Board of Directors where the compensation of the Board Members and 
the compensation of the Executive Managers are discussed. However, discussions and decisions of the Board of Directors and of 
the  Compensation  Committee  regarding  the  compensation  of  the  CEO  are  resolved  in  his  absence.  The  other  members  of  the 
Executive Management do not attend the meetings of the compensation Committee nor the parts of the meetings of the Board of 
Directors, where the compensation of the Board Members or the compensation of the Executive Managers are discussed. Board 
Members, who are not members of the Compensation Committee, do not attend the meetings of the Compensation Committee, but 
take  part  in  the  meetings  of  the  Board  of  Directors  during  which  the  compensation  of  the  Board  Members  is  discussed  and  the 
compensation of the Executive Managers as well as the vote relating thereto. 

In  its  review  process  the  Compensation  Committee  considers  compensation  packages  of  other  companies  in  the  biotech  and 
pharmaceutical industry in Switzerland and Europe that are comparable to Addex with respect to size and business model, considering 
the professional experience and areas of responsibility of the respective members of the Board of Directors and Executive Managers. 
In  2020,  a  compensation  benchmarking  study  has  been  conducted  by  a  reputable,  independent  expert  firm  which  has  not  been 
awarded  additional  mandates  by  the  Company.  This  benchmarking  study  has  contributed  to  the  Compensation  Committee’s 
assessment of the appropriateness of the Company’s compensation level and structure for the 2021 and 2022 business years. In this 
benchmarking study, compensation data of Swiss and European listed companies from the biotech sector with a similar size and 
stage  of  development  to  Addex  were  collected  and  used  to  establish  compensation  levels  and  structure.  The  Compensation 
Committee also consults relevant compensation surveys and benchmarking reports. Based on the detailed review process of the 
Compensation Committee, the Board of Directors submits two proposals for approval at the shareholders meeting: (i) the maximum 
aggregate amount of fixed and variable compensation for the Board of Directors for the prospective period from one ordinary general 
meeting of shareholders to the following ordinary general meeting of shareholders; and (ii) the maximum aggregate amount of fixed 
and variable compensation for the Executive Management for the period from January 1 to December 31 of the next financial year. 
Approval  of  these  proposals  requires  an  absolute  majority  (more  than  50%  of  the  share  votes  represented  at  the  shareholders 
meeting). 

Compensation elements for the Board of Directors and Executive Management 

Board of Directors 

The compensation of the non-executive board members mostly includes variable elements whilst executive board members are not 
remunerated as board member. The fixed element comprises a fixed annual monetary compensation per Board term from one general 
meeting of shareholders to the next. The variable element comprises a monetary compensation based on Board meeting attendance 
and the fair value of equity incentive units (share options and equity sharing certificates) and represents from 50% to 250% of fixed 
annual compensation. Nevertheless, in 2022, the variable compensation of the chairman of the Board of Directors and of the chairman 
of the compensation committee represented fourteen and thirteen time their fixed annual compensation respectively, primarily due to 

Page 21 of 70 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Addex Therapeutics Annual Report 2022 │Compensation Report 

the increased fair value of their options granted as the exercise prices have been reduced (See note 13). Social security contributions 
of the Company are accrued on the fixed and variable elements. Board member social security contributions are accrued on the fair 
value of equity incentive units. Equity incentive units are granted based on the discretion of the Board of Directors. Equity incentive 
units are granted to compensate for the dilutive effects of capital raising to ensure Board Members have sufficient unvested equity 
incentive units in accordance with external benchmarks. The most recent review of compensation for members of the Board took 
place  in  October  2022.  For  further  information  on  the  compensation  for  members  of  the  Board,  please  refer  to  the  section 
“Compensation of the Board in 2022" on page 23. 

Executive Management 

The compensation of members of the Executive Management consists of fixed and variable elements. The fixed element may include 
a base salary or a cash retainer paid under a consulting contract. The variable element may include performance-related cash or 
share based bonuses, consulting fees based on chargeable hours and equity incentive units (equity sharing certificates and share 
options). Company contributions to pension plans, death and invalidity insurances and social security contributions are accrued on 
all fixed and variable element compensation that relates to an employment relationship. Company social security contributions are 
accrued for all shares or equity incentive unit compensation. The amount of the fixed element depends on the position, responsibilities, 
experience and skills, and takes into account individual performance. The fixed element is reviewed at the end of each year by the 
Board. Any changes in the fixed elements are made effective in January of the following year. The variable elements are based on 
individual  and  company  goals.  The  potential  variable  cash  bonus  is  determined  in  the  employment  contract  and  in  general  is  a 
percentage of the base salary. Where the Executive Manager has been engaged under a consulting contract, the variable element is 
based  on  the  time spent  at  the  contractually  defined  rate  of  remuneration.  Every year,  the  Board  decides on  the  total amount  of 
variable  elements  including  the  amount  of  cash  and  equity  incentive  units  to  be  granted  for  the  previous  year  based  on  the 
achievement of Company and Individual goals. Equity incentive units are granted based on the discretion of the Board of Directors. 
Variable cash compensation paid to Executive Managers includes bonus and equity incentive units. The variable compensation of 
CEO is determined 100% based on company goals and includes a cash bonus representing from 0% to 50% of base salary and 
equity incentive units representing from 0% to 150% of base salary, exceptionally increased to seven times of base salary in 2022 
primarily due to the higher fair value of his equity incentive units following the reduction of the exercise prices. Our Chief Medical 
Officer (“CMO”) is engaged through a consultancy agreement and invoices the company for hours worked on a monthly basis which 
are settled in cash. In addition, equity incentive units are granted from time to time at the discretion of the Board of Directors. The 
variable compensation of the other Executive Managers includes a cash bonus representing from 0% to 25% of base salary and is 
determined based on 20% individual goals and 80% company goals, and equity incentive units representing 0% to 100% of base 
salary, exceptionally increased up to 182% of base salary in 2022 primarily due to the increased fair value of their equity incentive 
units granted following the reduction of the exercise prices. In addition, the Board of Directors grants equity incentive units to Executive 
Managers  to  compensate  for  the  dilutive  effects  of  capital  raising  to  ensure  Executive  Managers  have  sufficient  unvested  equity 
incentive units in accordance with external benchmarks.   

The company goals for 2022 were established at the beginning of the year as follows:   

Execution of dipraglurant phase 2b/3 PD LID study (study 301)  
Execution of dipraglurant phase 2a blepharospasm study 
Advancing GABAB PAM to end of clinical candidate selection  
Advancing other discovery programs to end of clinical candidate selection 
Securing the Group’s financial situation  
Maintain effective governance, regulation and administration  

30% 
15% 
15% 
15% 
20% 
  5%  

Following the termination of the dipraglurant clinical development in PD LID in June 2022, the company goals were realigned with the 
Group’s revised strategy which primarily resulted in the dipraglurant phase 2b/3 PD LID study execution goal being replaced by an 
objective to efficiently and effectively close down the PD LID development in a cost-effective manner with a weighting of 15%. In 
addition, the percentage weighting of 20% for “securing the Group’s financial situation” was increased to 35%.  

The  individual  goals  of  the  Executive  Managers  for  2022  were  as  follows:  1)  Deliver  novel  drug  candidates  weighted  at  50%;  2) 
Develop collaborative arrangements to efficiently advance preclinical portfolio weighted at 25%; and 3) Develop novel tools to identify 
and characterize allosteric modulators weighted at 25%.  

Equity incentive plans 

The purpose of the Group’s share purchase, share option and equity sharing certificate programs (refer to note 13 of the consolidated 
financial statements) is to provide members of the Board of Directors, Executive Management, employees and certain consultants 
(together “Staff”) with an opportunity to benefit from the potential appreciation in the value of the Company’s shares, thus providing 
an increased incentive for participants to contribute to the future success and prosperity of the Group, enhancing the value of the 
shares for the benefit of the shareholders of the Group  and increasing the ability of the Group to attract and retain individuals of 
exceptional skills. In addition, these plans provide the Group with a mechanism to engage services for non-cash consideration by 
settling  them  through  a  transfer  of  treasury  shares  under  the  share  purchase  plan  based  on  predefined  terms  of  the  consulting 
contract. The grant of any share option or equity sharing certificate is at the discretion of the Board of Directors. Key factors considered 
by the Board of Directors in making grants of share options or equity sharing certificates are the amount of shareholder approved 
conditional capital, the benchmarking with other companies as well as individual performance (for further information on the detail 
and composition of the benchmark please refer to the paragraph review and approval process above). The strike price is determined 

Page 22 of 70 

 
 
 
 
 
  
 
 
 
 
 
Addex Therapeutics Annual Report 2022 │Compensation Report 

by the Board of Directors and is primarily based on the closing price of the Company’s shares on the SIX Swiss Exchange on the 
grant  date.  In  addition,  the  Group  has  implemented  a  staff  retention  plan  which  includes  a  deferred  strike  price  payment  plan 
(“DSPPP”) which encourages Board Members, Executive Managers and employees to exercise their share options or equity sharing 
certificates  and  become  shareholders  of  the  Company  by  allowing  deferral  of  the  obligation  to  pay  the  strike  price  on  exercise 
("Deferred Strike Price Payment Obligations"). 

Indirect benefits 

The Company may contribute to the pension plan and maintains certain insurance for death and invalidity for the members of the 
Executive Management. New entrants may be eligible for reimbursement of relocation costs, compensation for lost benefits or stock 
granted by a previous employer, international school for children or language courses for a limited time period. No Indirect benefits 
have been paid to Executive Management in 2022. 

Special conditions in case of change of control 

In the event of a change of control of the company, three Executive Managers are entitled to receive an amount equivalent to one 
time the annual gross salary and 1.5 times the targeted annual bonus 12 months after the change of control, unless they have given 
notice of termination or have received notice of termination for cause.  

Compensation for the financial year under review (audited)

REPORT OF THE STATUTORY AUDITOR 

To the General meeting of Addex Therapeutics Ltd, Plan-les-Ouates 

Report on the Audit of the Compensation Report 

Opinion 

We have  audited  the  Compensation Report of Addex Therapeutics Ltd  (the  Company) for the year 
ended  December  31,  2022. The  audit  was  limited  to  the  information on  remuneration,  loans  and 
advances pursuant to Art. 14-16 of the Ordinance against Excessive Remuneration in Listed Companies 
bei 
Limited 
börsenkotierten  Aktiengesellschaften, VegüV) in the  tables marked «audited»  on pages 21  to 24 
of the Compensation Report.

by 

In  our  opinion,  the  information  on  remuneration,  loans  and  advances  in  the  accompanying 
Compensation Report (pages 21 to 24) complies with Swiss law and Art. 14-16 VegüV.  

Basis for Opinion 

We conducted our audit in accordance with Swiss law and Swiss Standards on Auditing (SA-CH). Our 
responsibilities  under  those  provisions  and  standards  are  further  described  in  the  Auditor’s 
Responsibilities for the Audit of the Compensation Report section of our report. We are independent 
of the  Company in accordance with the provisions of Swiss law and  the  requirements of the  Swiss 
audit  profession, and   we  have  fulfilled  our  other  ethical  responsibilities  in  accordance  with  these 
requirements.  

We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis 
for our opinion. 

Other Information 

The Board of Directors is responsible for the other information. The other information comprises the 
information included in the annual report, but does not include the tables marked «audited» in the 
Compensation  Report,  the  consolidated  financial  statements,  the  stand-alone  financial  statements 
and our auditor’s reports thereon. 

Our opinion on the Compensation Report does not cover the other information and we do not express 
any form of assurance conclusion thereon. 

In  connection  with  our  audit  of  the Compensation  Report,  our  responsibility  is  to  read  the  other 
information and, in doing so, consider whether the other information is materially inconsistent with 
the audited financial information in the Compensation Report or our knowledge obtained in the audit 
or otherwise appears to be materially misstated. 

If, based on the work we have performed, we conclude that there is a material misstatement of this 
other information,we are required to report that fact. We have nothing to report in this regard.  

Board of Directors' Responsibilities for the Compensation Report 

The  Board  of  Directors  is  responsible  for  the  preparation  of  a  Compensation  Report  in 
accordance  with  the  provisions  of  Swiss  law  and  the  Company's  articles  of  incorporation,  and  for 
such internal control as the Board of Directors determines is necessary to enable the preparation of a 
Compensation Report that is free from material misstatement, whether due to fraud or error.  The 
Board  of  Directors  is  also  responsible  for  designing  the  remuneration  system  and  defining 
individual  remuneration  packages. 

BDO Ltd, a limited company under Swiss law, incorporated in Zurich, forms part of the international BDO Network of independent member firms.

Addex Therapeutics Annual Report 2022 │Compensation Report 

Auditor’s Responsibilities for the Audit of the Compensation Report 

Our objectives are to obtain reasonable assurance about whether the information on remuneration, 
loans and advances pursuant to Art. 14-16 VegüV is free from material misstatement, whether due to 
fraud or error, and to issue an auditor’s report that includes our opinion. Reasonable assurance is a 
high level of assurance, but is not a guarantee that an audit conducted in accordance with Swiss law 
and SA-CH will always detect a material misstatement when it exists. Misstatements can arise from 
fraud or error and are considered material if, individually or in the aggregate, they could reasonably 
be expected to influence the economic decisions of users taken on the basis of this Compensation 
Report. 

As part of an audit in accordance with Swiss law and SA-CH, we exercise professional judgment and 
maintain professional skepticism throughout the audit. We also: 

•

Identify and assess the risks of material misstatement in the Compensation Report, whether due
to fraud or error, design and perform audit procedures responsive to those risks, and obtain audit
evidence that is sufficient and appropriate to provide a basis for our opinion. The risk of not
detecting  a  material  misstatement  resulting  from  fraud  is  higher  than  for  one  resulting  from
error, as fraud may involve collusion, forgery, intentional omissions, misrepresentations, or the
override of internal control

• Obtain  an  understanding  of  internal  control  relevant  to  the  audit  in  order  to  design  audit
procedures that are appropriate in the circumstances, but not for the purpose of expressing an
opinion on the effectiveness of the Company’s internal control.

•

Evaluate the appropriateness of accounting policies used and the reasonableness of accounting
estimates and related disclosures made.

We  communicate  with  the  Board  of  Directors  or  its  relevant  committee  regarding,  among  other 
matters,  the  planned  scope  and  timing  of  the  audit  and  significant  audit  findings,  including  any 
significant deficiencies in internal control that we identify during our audit. 

We  also  provide  the  Board  of  Directors  or  its  relevant  committee  with  a  statement  that  we  have 
complied with relevant ethical requirements regarding independence, and to communicate with them 
all relationships and other matters that may reasonably be thought to bear on our independence, and 
where applicable, actions taken to eliminate threats or safeguards applied.

Addex Therapeutics Annual Report 2022 │ Consolidated Financial Statements Notes 

Notes to the Consolidated Financial Statements 
for the years ended December 31, 2022 and 2021 
(Amounts in Swiss francs) 

1.  General information 

Addex  Therapeutics Ltd (the  “Company”),  formerly  Addex  Pharmaceuticals  Ltd,  and its  subsidiaries  (together,  the  “Group”)  are  a 
clinical stage pharmaceutical group applying its leading allosteric modulator drug discovery platform to discovery and development 
of small molecule pharmaceutical products, with an initial focus on central nervous system disorders.  

The Company is a Swiss stockholding corporation domiciled c/o Addex Pharma SA, Chemin des Aulx 12, CH1228 Plan-les-Ouates, 
Geneva, Switzerland and the parent company of Addex Pharma SA, Addex Pharmaceuticals France SAS and Addex Pharmaceuticals 
Inc.  registered  in  Delaware,  United  States.  Its  registered shares  are  traded at the  SIX,  Swiss  Exchange,  under  the  ticker  symbol 
ADXN. On January 29, 2020, the Group listed on the Nasdaq Stock Market, American Depositary Shares (ADSs) under the symbol 
“ADXN”, without a new issuance of securities. ADSs represents shares that continue to be admitted to trading on SIX Swiss Exchange. 

These consolidated financial statements have been approved for issuance by the Board of Directors on March 29, 2023.  

2.  Summary of significant accounting policies 

The  principal  accounting  policies  applied  in  the  preparation  of  these  consolidated  financial  statements  are  set  out  below.  These 
policies have been consistently applied to all the years presented, unless otherwise stated. 

2.1  Basis of preparation 

The  consolidated  financial  statements  of  Addex  Therapeutics  Ltd  have  been  prepared  in  accordance  with  International  Financial 
Reporting  Standards  (IFRS)  as  issued  by  the  International  Accounting  Standards  Board  (“IASB”),  and  under  the  historical  cost 
convention. 

The preparation of financial statements in conformity with IFRS requires the use of certain critical accounting estimates. It also requires 
management to exercise its judgment in the process of applying the Group's accounting policies. The areas involving a higher degree 
of judgment or complexity, or areas where assumptions and estimates are significant to the consolidated financial statements are 
disclosed in note 4 “Critical accounting estimates and judgements”. 

Due  to  rounding,  numbers  presented  throughout  these  consolidated  financial  statements,  may  not  add  up  precisely  to  the  totals 
provided. All ratios and variances are calculated using the underlying amount rather than the presented rounded amount. 

Where necessary, comparative figures have been revised to conform with the current year 2022 presentation. 

2.2  Standards and interpretations published by the IASB 

New and amended standards adopted by the Group 

A number of new or amended standards and interpretations became applicable for financial periods beginning on or after January 1, 
2022. The Group noted that the latter did not have a material impact on the Group’s financial position or disclosures made in the 
condensed consolidated financial statements. 

New standards and interpretations not yet adopted by the Group 

The  Group  is  currently  assessing  the  potential  impacts  of  the  various  new  and  revised  standards  and  interpretations  that  will  be 
mandatory from January 1, 2023 which the Group has not yet applied. Based on an analysis to date, the Group does not anticipate 
that these will have a material impact on the Group’s overall results and financial position. The Group is also assessing other new 
and revised standards which are not mandatory until after 2023.  

2.3  Consolidation 

Subsidiaries are all entities over which the Group has control. The Group controls an entity when the Group is exposed to, or has 
rights to, variable returns from its involvement with the entity and has the ability to affect those returns through its power over the 
entity. Subsidiaries are fully consolidated from the date on which control is transferred to the Group. They are de-consolidated from 
the date that control ceases. 

The  Company  currently  consolidates  the  financial  operations  of  its  three  fully-owned  subsidiaries,  Addex  Pharma  SA,  Addex 
Pharmaceuticals Inc., and Addex Pharmaceuticals France SAS.

Addex Therapeutics Annual Report 2022 │ Consolidated Financial Statements Notes 

Inter-company transactions, balances and unrealized gains on transactions between Group companies are eliminated. Unrealized 
losses are also eliminated unless the transaction provides evidence of an impairment of the asset transferred. Accounting policies of 
subsidiaries have been changed where necessary to ensure consistency with the policies adopted by the Group. The reporting date 
of all Group companies is December 31. 

2.4  Segment reporting 

The Group operates in one segment, which is the discovery, development and commercialization of small-molecule pharmaceutical 
products. A single management team that reports to the Chief Executive Officer comprehensively manages the entire business. The 
chief operating decision-maker is the Chief Executive Officer who reviews the statement of operations of the Group on a consolidated 
basis, makes decisions  and manages  the operations  of  the  Group  as  a single operating  segment.  The  Group’s  activities  are not 
affected by any significant seasonal effect. Revenue is attributable to the Company’s country of domicile, Switzerland. 

2.5  Foreign currency transactions 

Functional and presentation currency 
Items included in the financial statements of each of the Group's entities are measured using the currency of the primary economic 
environment in which the entity operates ("the functional currency"). The consolidated financial statements are presented in Swiss 
francs, which is the Group’s presentation currency.   

Transactions and balances 
Foreign  currency  transactions  are  translated  into  the  functional  currency  using  the  exchange  rates  prevailing  at  the  dates  of  the 
transactions or valuation where items are re-measured. Foreign exchange gains and losses resulting from the settlement of such 
transactions and from the translation at year-end exchange rates of monetary assets and liabilities denominated in foreign currencies 
are recognized in the statement of comprehensive loss. 

Foreign  exchange  gains  and  losses  that  relate  to  borrowings  and  cash  and  cash  equivalents  are  presented  in  the  statement  of 
comprehensive loss within ‘finance result’.  

Group companies 
The results and financial position of the Group's subsidiary that has a functional currency different from the presentation currency are 
translated into the presentation currency as follows: 

• 
• 
• 

assets and liabilities for each balance sheet presented are translated at the closing rate at the date of that balance sheet; 
income and expenses for each statement of comprehensive loss are translated at the average exchange rate; and 
all resulting exchange differences are recognized in other comprehensive loss. 

2.6  Property, plant and equipment  

Property, plant and equipment are stated at historical cost less accumulated depreciation, and impairment (if any). Historical cost 
includes expenditure that is directly attributable to the acquisition of the item. Subsequent costs are included in the asset's carrying 
amount or recognized as a separate asset, as appropriate, only when it is probable that future economic benefits associated with the 
item will flow to the Group and the cost of the item can be measured reliably. All other repairs and maintenance are charged to the 
statement of comprehensive loss during the financial period in which they are incurred. Depreciation is calculated using the straight-
line method to allocate their cost to their residual values over their estimated useful lives as follows: 

Computer equipment 
Laboratory equipment 
Furniture and fixtures 
Chemical library 

3 years 
4 years 
5 years 
5 years 

The assets' residual values and useful lives are reviewed, and adjusted if appropriate, at each balance sheet date. An asset's carrying 
amount is written down immediately to its recoverable amount if the asset's carrying amount is greater than its estimated recoverable 
amount  (see  note 2.7).  Gains  and  losses  on  disposals  are determined by  comparing  proceeds  with the  carrying amount  and are 
included in the statement of comprehensive loss. 

2.7  Impairment of non-financial assets 

Assets that are subject to depreciation or amortization are reviewed for impairment annually, and whenever events or changes in 
circumstances indicate that the carrying amount may not be recoverable. An impairment loss is recognized for the amount by which 
the asset's carrying amount exceeds its recoverable amount. The recoverable amount is the higher of an asset's fair value less costs 
to  sell  and  value  in  use.  For  the  purposes  of  assessing  impairment,  assets  are  grouped  at  the  lowest  levels  for  which  there  are 
separately identifiable cash flows (cash generating units). Prior impairment of non-financial assets other than goodwill is reviewed for 
possible reversal at each reporting date.

2.8  Financial assets 

The Group has one category of financial assets, namely “trade and other receivables”. Trade and other receivables are non-derivative 
financial assets with fixed or determinable payments that are not quoted in an active market. These assets are held for collection of 
contractual cash flows which represent solely the payment of principal and interest. They arise when the Group provides money, 
goods  or  services  directly  to  a  debtor  with  no  intention  of  trading  the  receivable.  They  are  included  in  current  assets,  except  for 
maturities  greater  than  12  months  after  the  balance  sheet  date,  which  are  classified  as  non-current  assets.  Trade  and  other 
receivables are included in other current assets in the balance sheet (see note 7). 

Trade and other receivables are initially measured at fair value and subsequently measured at amortized cost. The amortized cost of 
a financial asset is the amount at which the financial asset is measured at initial recognition minus the principal repayments, plus the 
cumulative amortization using the effective interest method of any difference between that initial amount and the maturity amount, 
adjusted for  any  loss  allowance.  The  gross carrying  amount  of  a  financial  asset  is  the amortized  cost  of  a  financial asset  before 
adjusting for any loss allowance. Trade and other receivables are derecognized when settled.  

The Group classifies a contract asset as a receivable when the Group’s right to consideration is unconditional. If the Group transfers 
control of goods or services to a customer before the customer pays consideration, the Group records either a contract asset or a 
receivable depending on the nature of the Group’s right to consideration for its performance.  Contract assets and contract liabilities 
arising from the same contract are netted and presented as either a single net contract asset or net contract liability. 

Impairment of financial assets 
The Group recognizes a loss allowance for expected credit losses on trade and other receivables, contract assets and security rental 
deposits  that  are  measured  at  amortized cost.  The amount  of  expected  credit  losses is updated  at  each  reporting  date  to  reflect 
changes in credit risk since initial recognition of the respective financial instrument. 

The  Group  always  recognizes  lifetime  expected  credit  losses  (“ECL”)  for  trade  and  other  receivables  and  contract  assets  where 
applicable.  The  ECL  on  these  financial  assets  are  estimated  using  a  provision  matrix  based  on  the  Group’s  historical credit  loss 
experience, adjusted for factors that are specific to the debtors, general economic conditions and an assessment of both the current 
as well as the forecast direction of conditions at the reporting date, including time value of money where appropriate. 

Lifetime ECL represents the ECL that will result from all possible default events over the expected life of a financial instrument. In 
contrast, 12-month ECL represents the portion of lifetime ECL that is expected to result from default events on a financial instrument 
that are possible within 12 months after the reporting date.  

2.9  Cash and cash equivalents 

Cash and cash equivalents include cash on hand, deposits held at call with banks and other short-term highly liquid investments with 
original maturities of three months or less. They are both readily convertible to known amounts of cash and so near their maturity that 
they present insignificant risk of changes in value because of changes in interest rates. Any bank overdrafts are not netted against 
cash and cash equivalents but are shown as part of current liabilities on the consolidated balance sheet. 

2.10  Share capital 

Shares are classified as equity. Incremental costs directly attributable to the issue of new shares are shown as a deduction, net of 
tax, from the proceeds. 

Where any Group company purchases the Company's equity share capital (treasury shares), the consideration paid, including any 
directly attributable incremental cost (net of income taxes) is recorded as a deduction from equity attributable to the Company's equity 
holders as a treasury share reserve until the shares are cancelled, reissued or disposed of. When such shares are subsequently sold 
or reissued, any consideration received, net of any directly attributable incremental transaction costs and the related income tax effect, 
the nominal amount is reversed from the treasury share reserve, with any remaining difference to the total transaction value being 
recognized in share premium.  

The Company has entered into a liquidity contract where an independent broker buys and sells the Company’s shares held in the 
broker’s  custody.    Such  shares  are  presented  in  the  treasury  share  reserve  with  all  other  treasury  shares directly  held by  Addex 
Pharma SA.  

The Group also uses treasury shares to partially settle services rendered by third and related parties. When shares are issued for this 
purpose, the nominal share value is recognized as a treasury share reserve and the value above par is presented as a share premium.  

2.11  Equity instruments 

Equity instruments issued by the Group are recorded at the fair value of the proceeds received, net of direct issuance costs.

Addex Therapeutics Annual Report 2022 │ Consolidated Financial Statements Notes 

2.12  Trade payables 

Trade payables are recognized initially at fair value and subsequently measured at amortized cost using the effective interest method. 
All payables have a contract maturity within 1 year. 

2.13  Grants 

Grants are not recognized until there is reasonable assurance that the Group will comply with the terms and conditions of the grant 
and that the grants will be received. Grants are recognized as other income in the statement of comprehensive loss on a systematic 
basis over the periods in which the Group recognizes as expenses the related costs for which the grant is intended to compensate. 
Specifically, grants whose primary conditions are that the Group should undertake specific research activities within a defined period 
of time, are recognized as deferred income in the consolidated statement of financial position and transferred to the statement of 
comprehensive loss on a systematic and rationale basis over the defined timeframe. 

2.14  Deferred income tax 

Deferred income tax is recorded in full, using the liability method, on temporary differences arising between the tax bases of assets 
and liabilities and their carrying amounts in the consolidated financial statements. However, if the deferred income tax arises from 
initial recognition of an asset or liability in a transaction other than a business combination that at the time of the transaction affects 
neither accounting nor taxable profit or loss, it is not accounted for. Deferred income tax is determined using tax rates and laws that 
have been enacted or substantively enacted by the balance sheet date and are expected to apply when the related deferred income 
tax asset is realized, or the deferred income tax liability is settled. 

Deferred income tax assets are recognized to the extent that it is probable that future taxable profit will be available against which the 
temporary differences can be utilized. 

Deferred income tax is recorded on temporary differences arising on investments in subsidiaries, except where the Group deems it 
probable that the temporary difference will not reverse in the foreseeable future. 

Potential deferred income tax assets from tax loss carry forwards exceed deferred tax liabilities. Deferred income tax assets from tax 
loss carry forwards are initially recognized to the extent that the realization of the related tax benefit through future taxable profits is 
probable. 

2.15  Pension obligations 

The Group operates one pension scheme. The scheme is generally funded through payments to insurance companies or trustee-
administered funds, determined by periodic actuarial calculations. The Group has defined benefit plans. A defined benefit plan is a 
pension plan that defines an amount of pension benefit that an employee will receive on retirement, usually dependent on one or 
more  factors  such  as  age,  years  of  service  and  compensation.  Actuarial  gains  and  losses  arising  from  experience  adjustments, 
changes in actuarial assumptions and changes in the asset ceiling effect are recognized immediately in other comprehensive loss 
and past-service costs are recognized immediately in statement of comprehensive loss. 

Under IAS 19, the shortfall or the surplus of the fair value of the plan assets compared with the defined benefit obligation is recorded 
as a liability or an asset in the consolidated balance sheet. That recognition is subject to asset ceiling rules and minimum funding 
requirements set out in IFRIC 14.  The defined benefit obligation is calculated at least annually by an independent actuary using the 
projected unit credit method. The present value of the defined benefit obligation is determined by discounting the estimated future 
cash outflows using interest rates of high-quality corporate bonds that are denominated in the currency in which the benefits will be 
paid, and that have terms to maturity approximating to the terms of the related pension liability. 

2.16  Share-based compensation 

The Group operates an equity sharing certificates’ equity incentive plan, a share option plan, and a share purchase plan. The Group 
also from time-to-time grants warrants to brokers and investors. The fair value of the services received in exchange for the grant or 
transfer  of equity sharing certificates, options,  shares  or  warrants is  recognized in  the  consolidated  financial statements  over  the 
period for which the services are received. The total amount to be recognized over the vesting period is determined by reference to 
the fair value of the equity incentive unit granted or transferred. The fair value of instruments granted includes any market performance 
conditions  and  excludes  the  impact  of  any  service  and  non-market  performance  vesting  conditions.  Service  and  non-market 
performance conditions are included in assumptions about the number of equity incentive units that are expected to vest. At each 
balance sheet date, the Group revises its estimates for the number of equity incentive units that are expected to vest. It recognizes 
the impact of the revision to original estimates, if any, in the statement of comprehensive loss, with a corresponding adjustment to 
equity. 

The  proceeds  received  net  of  any  directly  attributable  transaction  costs  are  credited  to  share  capital  (nominal  value)  and  share 
premium when the equity incentive units are exercised.

2.17  Revenue recognition 

The Group recognizes revenue from the license of intellectual property and providing research and development services:   
License of intellectual property 
If the license to the Group’s intellectual property is determined to be distinct from the other performance obligations identified in the 
arrangement, the Group recognizes revenues when the license conveys a right of use, or there is a right of access to the underlying 
intellectual property. For licenses that are sold in conjunction with a related service, the Group uses judgment to assess the nature of 
the combined performance obligation to determine whether the combined performance obligation is satisfied over time or at a point 
in time. If the performance obligation is settled over time, the Group determines the appropriate method of measuring progress for 
purposes of recognizing license revenue. The Group evaluates the measure of progress each reporting period and, if necessary, 
adjusts the measure of performance and related revenue recognition. 

Research and development services 
The Group has an arrangement with its partner that includes deploying its employees for research and development activities. The 
Group assesses if these research and development activities are considered distinct in the context of the respective contract and, if 
so,  they  are  accounted  for  as  a  separate  performance  obligation.  This  revenue  is  calculated  based  on  the  costs  incurred  (input 
method) in accordance  with the  respective  contract and  recorded  within  “Revenue  from contract  with  customer”  over  time  as the 
activities are performed. 

Contract balances 
The Group receives payments and determines credit terms from its customers for its various performance obligations based on billing 
schedules established in each contract. The actual timing of the income recognition, billings and cash collections may result in other 
current  receivables,  accrued  revenue  (contract  assets),  and  deferred  revenue  (contract  liabilities)  being  recorded  on  the  balance 
sheet. Amounts are recorded as other current receivables when the Group’s right to consideration is unconditional. The Group does 
not assess whether a contract has a significant financing component if the expectation at contract inception is such that the period 
between payment by the customer and the transfer of the promised goods or services to the customer will be one year or less. 

Under IFRS 15, the Group recognizes as revenue its non-refundable license fees, milestone, research activities and royalties when 
its customer obtains control of promised services, in an amount that reflects the consideration which the Group expects to receive in 
exchange for those rendered services. To assess revenue recognition for arrangements that the Group determines are within the 
scope of IFRS 15, the Group performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance 
obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the 
contract; and (v) recognize revenue when (or as) the Group satisfies a performance obligation. The Group only applies the five-step 
model to contracts when it is probable that the Group will collect the consideration it is entitled to in exchange for services it transfers 
to the customer. At contract inception, once the contract is determined to be within the scope of IFRS 15, the Group assesses the 
services promised within each contract and determine those that are performance obligations and assess whether each promised 
service is distinct. The Group uses the most likely method to estimate any variable consideration and include such consideration in 
the  amount  of  the  transaction  price  based  on  an  estimated  stand-alone  selling  price.  Revenue  is  recognized  for  the  respective 
performance obligation when (or as) the performance obligation is satisfied. 

2.18  Finance income and expense 

Interest received or paid on cash and cash equivalents are classified in the statement of cash flows under financing activities. 

2.19  Leases 

The Group assesses whether a contract is or contains a lease, at inception of the contract. The Group recognizes a right-of-use asset 
and a corresponding lease liability with respect to all lease arrangements in which it is the lessee, except for short-term leases (defined 
as leases with a lease term of 12 months or less) and leases of low value assets (less than USD 5 thousand). For these leases, the 
Group recognizes the lease payments as an operating expense on a straight-line basis over the term of the lease unless another 
systematic basis is more representative of the time pattern in which economic benefits from the leased assets are consumed.  

The lease liability is initially measured at the present value of the lease payments as from the commencement date of the lease until 
the  expected  termination  date.  In  determining  the  lease  term,  management  consider  all  facts  and  circumstances  that  create  an 
economic incentive to exercise an extension option, or not to exercise a termination option. Extension option are only considered if 
the lease is reasonably certain to be extended. The assessment of reasonable certainty is only revised if a significant event or a 
significant change in circumstances, that is within the control of the lessees, occurs. The lease payments are discounted by using the 
rate implicit in the lease. If this rate cannot be readily determined, the Group uses its incremental borrowing rate, being the rate that 
the individual lessee would have to pay to borrow the funds necessary to obtain an asset of similar value to the right-of-use asset in 
a similar economic environment with similar terms, security and conditions. The lease liability is presented as a separate line in the 
consolidated  statement  of  financial  position.  The  interest  expense  is  presented  in  the  line  finance  expenses  in  the  consolidated 
statement of comprehensive loss. 

The right-of-use assets comprise the initial measurement of the corresponding lease liability, lease payments made at or before the 
commencement day, less any lease incentives received and any initial direct costs. They are subsequently measured at cost less 
accumulated depreciation and impairment losses. They are depreciated over the shorter period of lease term and useful life of the 
underlying asset. If a lease transfers ownership of the underlying asset or the cost of the right-of-use asset reflects that the Group 

Page 36 of 70 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Addex Therapeutics Annual Report 2022 │ Consolidated Financial Statements Notes 

expects to exercise a purchase option, the related right-of-use asset is depreciated over the useful life of the underlying asset. The 
depreciation  starts  at  the  commencement  date  of  the  lease.  The  right-of-use  assets  are  presented  as  a  separate  line  in  the 
consolidated statement of financial position. 
When  the  Group  renegotiates  the  contractual  terms  of  a  lease  with  the  lessor,  the  accounting  depends  on  the  nature  of  the 
modification: 
• 

if the renegotiation results in one or more additional assets being leased for an amount commensurate with the standalone price 
for the additional rights-of-use obtained, the modification is accounted for as a separate lease; 
in all other cases where the renegotiated increases the scope of the lease (whether that is an extension to the lease term, or one 
or more additional assets being leased), the lease liability is remeasured using the discount rate applicable on the modification 
date, with the right-of-use asset being adjusted by the same amount; 
if the renegotiation results in a decrease in the scope of the lease, both the carrying amount of the lease liability and right-of-use 
asset are reduced by the same proportion to reflect the partial or full termination of the lease with any difference recognized in the 
statement of comprehensive loss. The lease liability is then further adjusted to ensure the carrying amount reflects the amount of 
the renegotiated payments over the renegotiated term, with the modified lease payments discounted at the rate applicable on the 
modification date. The right-of-use asset is adjusted by the same amount.  

• 

• 

All lease payments on leases are presented as part of the cash flow from financing activities, except for the short-term and low value 
leases cash flows, which are booked under operating activities. 

2.20  Research and development 

Research and development costs are expensed as incurred. Costs incurred on development projects are recognized as intangible 
assets when the following criteria are fulfilled: 

it is technically feasible to complete the intangible asset so that it will be available for use or sale; 

• 
•  management intends to complete the intangible asset and use or sell it; 
• 
• 
• 

there is an ability to use or sell the intangible asset; 
it can be demonstrated how the intangible asset will generate probable future economic benefits; 
adequate  technical,  financial  and  other  resources  to  complete  the  development  and  to  use  or  sell  the  intangible  asset  are 
available; and 
the expenditure attributable to the intangible asset during its development can be reliably measured. 

• 

In the opinion of management, due to uncertainties inherent in the development of the Group's products, the criteria for development 
costs to be recognized as an asset, as prescribed by IAS 38, “Intangible Assets”, are not met. 

3.  Financial risk management 

3.1  Financial risk factors 

The Group's activities expose it to a variety of financial risks: market risk, credit risk, liquidity risk and capital risk. The Group's overall 
risk management program focuses on the unpredictability of financial markets and seeks to minimize potential adverse effects on the 
Group's financial performance. Risk management is carried out by the Group's finance department (Group Finance) under the policies 
approved by the Board. Group Finance identifies, evaluates and in some instances economically hedges financial risks in close co-
operation  with  the  Group's  operating  units.  The  Board  provides  written  guidance  for  overall  risk  management,  as  well  as  written 
policies covering specific areas, such as foreign exchange risk, interest-rate risk, use of derivative financial instruments and non-
derivative financial instruments, credit risk and investing excess liquidity. 

Market risk and foreign exchange risk 
The Group operates internationally and is exposed to foreign exchange risk arising from various exposures with respect to the Euro, 
US dollar and UK pound. Foreign exchange risk arises from future commercial transactions, recognized assets and liabilities and net 
investments in foreign operations. To manage foreign exchange risk Group Finance maintains foreign currency cash balances to 
cover anticipated future requirements. The Group's risk management policy is to economically hedge 50% to 100% of anticipated 
transactions in each major currency for the subsequent 12 months. The Group has a subsidiary in France and in United States of 
America, whose net assets are exposed to foreign currency translation risk. In 2022, a 10% increase or decrease in the EUR/CHF 
exchange rate would have resulted in a CHF 7,945 decrease or increase in net loss and shareholders’ equity as at December 31, 
2022 (2021: a CHF 7,948 increase or decrease), a 10% increase or decrease in the GBP/CHF exchange rate would have resulted in 
a CHF 1,470 increase or decrease in net loss and shareholders’ equity as at December 31, 2022 (2021: a CHF 17,893 decrease or 
increase)  and  a  10%  increase  or  decrease  in  the  USD/CHF  exchange  rate  would  have  resulted  in  a  CHF  175,837  (2021:  CHF 
1,027,027) increase or decrease in net loss and shareholders’ equity as at December 31, 2022. The Group is not exposed to equity 
price risk or commodity price risk as it does not invest in these classes of investment.  

Interest rate risk 
The Group’s exposure to interest rate fluctuations is limited because the Group has no interest-bearing indebtedness.  

Page 37 of 70 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Addex Therapeutics Annual Report 2022 │ Consolidated Financial Statements Notes 

Credit risk 
Credit risk is managed on a Group basis. Credit risk arises from cash and cash equivalents and deposits with banks, as well as credit 
exposures to collaboration partners. The Group has a limited number of collaboration partners and consequently has a significant 
concentration  of  credit  risk.  The  Group  has  policies  in  place  to  ensure  that  credit  exposure  is  kept  to  a  minimum  and  significant 
concentrations of credit risk are only granted for short periods of time to high credit quality partners. The Group's policy is to invest 
funds in low-risk investments including interest bearing deposits. For banks and financial institutions, only independently rated parties 
with a minimum rating of “A” are accepted (see note 6). 

Liquidity risk 
The Group's principal source of liquidity is its cash reserves which are obtained through the sale of new shares and to a lesser extent 
the  sale  of  its  research  and  development  stage  products.  Group  Finance  monitors  rolling  forecasts  of  the  Group’s  liquidity 
requirements to ensure it has sufficient cash to meet operational needs. The ability of the Group to maintain adequate cash reserves 
to sustain its activities in the medium term is highly dependent on the Group's ability to raise further funds from the licensing of its 
development stage products and the sale of new shares. Consequently, the Group is exposed to significant liquidity risk (see note 4).  

3.2  Capital risk management 

The Group is not regulated and not subject to specific capital requirements. The amount of equity depends on the Group’s funding 
needs and statutory capital requirements. The Group monitors capital periodically on an interim and annual basis. From time to time, 
the Group may take appropriate measures or propose capital increases to its shareholders to ensure the necessary capital remains 
intact. The Group did not have any short-term or long-term debt outstanding as of December 31, 2022 and 2021. 

The ability of the Group to maintain adequate cash reserves to continue its activities in the medium term is subject to risk as it is 
highly dependent on the Group’s ability to raise further funds from the sale of new shares. 

The  Group’s objectives  when managing capital  based on  its  net  debt  are  to safeguard  the  Group’s  ability  to  continue as a going 
concern in order to ensure the financing of successful research and development activities so that future profits can be generated 
and to maintain sufficient financial resources to mitigate against risks and unforeseen events.

3.3  Fair value estimation 

The nominal value less estimated credit adjustments of trade and other receivables, contract assets and payables are assumed to 
approximate to their fair values due to the short-term maturity of these instruments and are held at their amortized cost in accordance 
with  IFRS  9.  The  fair  value  of  other  financial  assets  and  liabilities  for  disclosure  purposes  is  estimated  by  discounting  the  future 
contractual cash flows at the current market interest rate that is available to the Group for similar financial instruments. 

4.  Critical accounting estimates and judgments 

The Group makes estimates and assumptions concerning the future. These estimates and judgments are continually evaluated and 
are based on historical experience and other factors, including expectations of future events that are believed to be reasonable under 
the circumstances. The resulting accounting estimates will, by definition, seldom equal the related actual results. The estimates and 
assumptions that have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities or may have 
had a significant impact on the reported results are disclosed below: 

Going concern 
The Group’s accounts are prepared on a going concern basis. To date, the Group has financed its cash requirements primarily from 
share issuances and licensing certain of its research and development stage products. The Group is a development-stage enterprise 
and is exposed to all the risks inherent in establishing a business. The Group expects that its existing cash and cash equivalents, at 
the  issuance  date  of  these  audited  consolidated  financial  statements,  will  be  sufficient  to  fund  its  operations  and  meet  all  of  its 
obligations  as  they  fall  due,  through  the  third  quarter  of  2023.  These  factors  individually  and  collectively  indicate  that  a  material 
uncertainty exists that raise substantial doubt about the Group's ability to continue as a going concern for one year from the date of 
issuance  of  these  audited  consolidated  financial  statements.  The  future  viability  of  the  Group  is  dependent  on  its  ability  to  raise 
additional  capital  through  public  or  private  financings  or  collaboration  agreements  to  finance  its  future  operations,  which  may  be 
delayed due to reasons outside of the Group’s control including the COVID-19 pandemic and the Russia’s invasion of Ukraine. The 
sale of additional equity may dilute existing shareholders. The inability to obtain funding, as and when needed, would have a negative 
impact on the Group’s financial condition and ability to pursue its business strategies. If the Group is unable to obtain the required 
funding to run its operations and to develop and commercialize its product candidates, the Group could be forced to delay, reduce or 
stop some or all of its research and development programs to ensure it remains solvent. Management continues to explore options 
to  obtain  additional  funding,  including  through  collaborations  with  third  parties  related  to  the  future  potential  development  and/or 
commercialization of its product candidates. However, there is no assurance that the Group will be successful in raising funds, closing 
collaboration  agreements,  obtaining  sufficient  funding  on  terms  acceptable to  the  Group,  or  if  at  all,  which  could  have  a  material 
adverse effect on the Group’s business, results of operations and financial condition.  

COVID-19 
In  early  2020  a  coronavirus  disease  (COVID-19)  pandemic  developed  globally  resulting  in  a  significant  number  of  infections  and 
negative effects on economic activity. The Group is actively monitoring the situation and is taking any necessary measures to respond 
to the situation in cooperation with the various stakeholders. On June 17, 2022 the Group terminated its dipraglurant US registration 
program including pivotal Phase 2B/3 and open label clinical trials of dipraglurant in levodopa-induced dyskinesia associated with 
Parkinson’s  disease  (PD-LID)  due  to  a  slow  recruitment  of  patients,  attributed  to  the  consequences  of  COVID-19  related  patient 
concerns about participation in clinical studies, as well as staffing shortages and turnover within study sites. Depending on the duration 
of the COVID-19 crisis and continued negative impact on global economic activity, the Group may have to take additional measures 
that will have a negative impact on the Group’s business continuity and may experience certain liquidity restraints as well as incur 
impairments on its assets. The exact impact on the Group’s activities in 2023 and thereafter cannot be reasonably predicted.  

Russia’s invasion of Ukraine  
On February 24, 2022, Russia invaded Ukraine. The resulting conflict and retaliatory measures by the global community have created 
global security concerns, including the possibility of expanded regional or global conflict, which have had, and are likely to continue 
to have, short-term and more likely longer-term adverse impacts on Ukraine and Europe and around the globe. Potential ramifications 
include disruption of the supply chain including research and development activities being conducted by the Group and its strategic 
partners. The Group and partners rely on global networks of contract research organizations to engage clinical study sites and enroll 
patients, certain of which are in Russia and Ukraine. Delays in research and development activities of the Group and its partners 
could increase associated costs and, depending upon the duration of any delays, require the Group and its partners to find alternative 
suppliers at additional expense. In addition, the conflict in Eastern Europe has had significant ramifications on global financial markets, 
which may adversely impact the ability of the Group to raise capital on favorable terms or at all.  

Revenue recognition 
Revenue is primarily from fees related to licenses, milestones and research services. Given the complexity of the relevant agreements, 
judgements are required to identify distinct performance obligations; allocate the transaction price to these performance obligations 
and determine when the performance obligations are met. In particular, the Group’s judgement over the estimated stand-alone selling 
price which is used to allocate the transaction price to the performance obligations is disclosed in note 14. 

Grants 
Grants are recorded at their fair value when there is reasonable assurance that they will be received and recognized as income when 
the Group has satisfied the underlying grant conditions. In certain circumstances, grant income may be recognized before explicit 
grantor acknowledgement that the conditions have been met.

Accrued research and development costs 
The Group records accrued expenses for estimated costs of research and development activities conducted by third party service 
providers. The Group records accrued expenses for estimated costs of research and development activities based upon the estimated 
amount of services provided, but not yet invoiced, and these costs are included in accrued expenses on the balance sheets and within 
research and development expenses in the statements of comprehensive loss. These costs are a significant component of research 
and development expenses. Accrued expenses for these costs are recorded based on the estimated amount of work completed in 
accordance with agreements established with these third parties. 

To date, the Group has not experienced significant changes in the estimates of accrued research and development expenses after a 
reporting period. However, due to the nature of estimates, the Group may be required to make changes to the estimates in the future 
as it becomes aware of additional information about the status or conduct of its research activities. 

Research and development costs 
The Group recognizes expenditure incurred in carrying out its research and development activities, including development supplies, 
until it becomes probable that future economic benefits will flow to the Group, which results in recognizing such costs as intangible 
assets, involving a certain degree of judgement. Currently, such development supplies are associated with pre-clinical and clinical 
trials of specific products that do not have any demonstrated technical feasibility. 

Deferred taxes 
Deferred tax is the tax expected to be payable or recoverable on differences between the carrying amounts of assets and liabilities in 
the financial statements and the corresponding tax bases used in the computation of taxable profit and is accounted for using the 
liability method.  Deferred  tax liabilities  are  generally  recognized  for  all  taxable  temporary differences  and  deferred  tax assets  are 
recognized to the extent that it is probable that taxable profits will be available against which deductible temporary differences can be 
utilized. The probability that taxable profits will be available is assessed by management based on business projections for each 
relevant entity. 

The carrying amount of deferred tax assets are reviewed at each reporting date and reduced to the extent that it is no longer probable 
that sufficient taxable profits will be available to allow all or part of the asset to be recovered. 

Deferred tax is calculated at the tax rates that are expected to apply in the period when the liability is settled, or the asset is realized 
based on tax laws and rates that have been enacted or substantively enacted at the reporting date. 

The  measurement  of  deferred  tax  liabilities  and  assets  reflects  the  tax  consequences  that  would  follow  from  the  way  the  Group 
expects, at the end of the reporting period, to recover or settle the carrying amount of its assets and liabilities. 

Deferred  tax  is  recognized  in  statement  of  comprehensive  loss,  except  when  related  to  items  that  are  recognized  in  other 
comprehensive loss or directly in equity, in which case, the current and deferred tax are recognized in other comprehensive loss or 
directly in equity. 

Share-based compensation 
The Group recognizes an expense for share-based compensation based on the valuation of equity incentive units using the Black-
Scholes valuation model. A number of assumptions related to the volatility of the underlying shares and to the risk-free rate are made 
in  this  model.  Should  the  assumptions  and  estimates  underlying  the  fair  value  of  these  instruments  vary  significantly  from 
management's estimates, then the share-based compensation expense would be materially different from the amounts recognized. 
Had these assumptions been modified within their feasible ranges, i.e. a 10% increase or decrease in the volatility assumption and a 
risk-free rate of 0.5 or zero, and the Group calculated the share-based compensation based on the higher and lower values of these 
ranges, share-based compensation expense in 2022 would have been CHF 3.0 million or CHF 4.3 million respectively (2021: CHF 
1.0 million or CHF 1.3 million, respectively). This is compared to the amount recognized as an expense in 2022 of CHF 3.7 million 
(2021: CHF 1.2 million). Additional information is disclosed in note 13. 

Pension obligations 
The present value of the pension obligations is calculated by an independent actuary and depends on a number of assumptions that 
are determined on an actuarial basis such as discount rates, future salary and pension increases, and mortality rates. Any changes 
in these assumptions will impact the carrying amount of pension obligations. The Group determines the appropriate discount rate at 
the end of each period. This is the interest rate that should be used to determine the present value of estimated future cash outflows 
expected to be required to settle the pension obligations. In determining the appropriate discount rate, the Group considers the interest 
rates of high-quality corporate bonds that are denominated in the currency in which the benefits will be paid, and that have terms to 
maturity approximating the terms of the related pension liability. Other key assumptions for pension obligations are based in part on 
current market conditions. Additional information is disclosed in note 19. 

5.  Segment information 

Management has identified one single operating segment, related to the discovery, development and commercialization of small-
molecule pharmaceutical products.

Other current assets decreased by CHF 0.6 million as of December 31, 2022 compared to December 31, 2021 including a decrease 
of CHF 0.8 million in prepayments primarily due to reduced prepaid amounts related to dipraglurant clinical development activities 
partially offset by an increase of CHF 0.3 million in the combined amount of contract assets, trade and other receivables primarily 
relating to the research agreement with Indivior. The Group applies the IFRS 9 simplified approach to measuring expected credit 
losses (“ECL”), which uses a lifetime expected loss allowance for all contract assets, trade receivables and other receivables. As of 
December 31, 2022, the combined amount of the contract asset, trade receivables and other receivables amounted to CHF 0.6 million 
(CHF 0.3 million as of December 31, 2021) including CHF 0.4 million for the research agreement with Indivior (CHF 0.2 million as of 
December 31, 2021), CHF 0.1 million for the grant from Eurostars/Innosuisse (CHF 0.1 million as of December 31, 2021). The Group 
has considered that the contract asset, trade receivables and other receivables have a low risk of default based on historic loss rates 
and  forward-looking  information  on  macroeconomic  factors  affecting  the  ability  of  the  third  parties  to  settle  invoices.  As  a  result, 
expected loss allowance has been deemed as nil as of December 31, 2022 and December 31, 2021.

SA and including the 17,438,883 shares issued on the exercise of equity incentive units on October 26, 2022 which are considered 
as treasury shares under IFRS 2 (See note 13). All shares have a nominal value of CHF 0.01 following the reduction of the nominal 
value  effective  on  July  26,  2022.  As  of  December  31,  2021,  37,898,149  shares  were  outstanding  excluding  11,374,803  treasury

The Group maintains a liquidity agreement with Kepler Cheuvreux. Under the agreement, the Group has provided Kepler with cash

equity incentive units at a strike price of CHF 0.13 by Board Members, Executive Managers and employees on October 26, 2022. 
The payment of the strike price has been deferred under the Group’s staff retention deferred strike price payment plan (“DSPPP”) 
and consequently, under IFRS 2, the 17,438,883 shares issued from the exercise of equity incentive units are considered as treasury 
shares. The 17,438,883 shares are considered to be legally owned by the exercising equity incentive unit holders on October 26, 
2022.   

On October 31, 2022, the Group increased its capital from CHF 652,730 to CHF 979,094 through the issuance of 32,636,476 new 
registered shares from its authorized capital to its fully owned subsidiary, Addex Pharma SA, at CHF 0.01 per share. These shares 
are held as treasury shares, hence the operation does not impact the outstanding share capital.

On June 1, 2010, the Company established an equity incentive plan based on equity sharing certificates (“ESCs”) to provide incentives 
to  Board  Members,  Executive  Managers,  employees  and  consultants  of  the  Group.  Each  ESC  provides  the  holder  (i)  a  right  to 
subscribe for 1,000 shares in the Company, and (ii) a right to liquidation proceeds equivalent to that of shareholders. All rights of the 
ESCs expire after their defined exercise period with the ownership of the ESCs reverting to the Group. ESCs granted are subject to 
certain vesting conditions based on the service period defined in each grant agreement. The holder of vested ESCs has the right to 
subscribe to shares at the subscription price if the underlying share price has reached the floor price. The floor and subscription price 
are defined by the Board of Directors in each grant agreement at the time of issuance. In the event of a change in control, all ESCs 
are automatically vested. The Group has no legal or constructive obligation to repurchase or settle ESCs in cash. 

Movements in the number of share subscription rights attached to the ESCs outstanding are as follows:

The Group has implemented a staff retention plan which includes a DSPPP which encourages Board Members, Executive Managers 
and employees to exercise their share options or equity sharing certificates and become shareholders of the Company by allowing 
the deferral of the obligation to pay the strike price until the earlier of the sale of the shares or 10 years. Shares received through the 
exercise of unvested share options are subject to sales restrictions reflecting the remaining vesting period of exercised equity incentive 
units. In the event of a change of control, bankruptcy of the Company or forced sale of the shares at a price below the strike price, 
the  deferred  strike  price  payment  obligation  is  waived.  Under  IFRS  2,  the  DSPPP  is  considered  to  be  a  non-recourse  loan  and 
consequently the options are deemed to be exercised on the date that the loan is repaid. Therefore, neither the shares nor the loan, 
are outstanding until either the options are exercised by paying the exercise price for the shares (repaying the loan) or the options 
expire entirely after 10 years without any remaining obligation from the option holders. The DSPPP is considered to be a modification 
of the equity incentive plan and consequently, the 17,438,883 shares (“DSPPP Shares”) issued from the exercise of equity incentive 
units are recorded as treasury shares and associated share-based compensation is recognized over the remaining vesting period as 
if the equity incentive units had not been exercised. The modification of the equity incentive plan results in an increase in the fair value 
of CHF 63,399 of which CHF 52,216 has been recognized in 2022.

Share purchase plan 

The Group established a share purchase plan under which services are settled for shares. Under the plan Board Members, Executive 
Managers, employees and consultants may receive fully paid ordinary shares from the Group’s treasury share reserve for services 
rendered. During the year ended December 31, 2022, the Group did not use its treasury shares to pay consultants whilst during the 
year ended December 31, 2021, 116,914 shares were transferred to settle CHF 164,980 of consulting fees. 

14.  Revenue from contract with customer 

License & research agreement with Indivior PLC 

On January 2, 2018, the Group entered into an agreement with Indivior for the discovery, development and commercialization of 
novel GABAB PAM compounds for the treatment of addiction and other CNS diseases. This agreement included the selected clinical 
candidate,  ADX71441.  In  addition,  Indivior  agreed  to  fund  a  research  program  at  the  Group  to  discover  novel  GABAB  PAM 
compounds.  

The contract contains two distinct material promises and performance obligations: (1) the selected compound ADX71441 which falls 
within the definition of a licensed compound, whose rights of use and benefits thereon was transferred in January 2018 and, (2) the 
research  services  to  be  conducted  by  the  Group  and  funded  by  Indivior  to  discover  novel  GABAB  PAM  compounds  for  clinical 
development that may be discovered over the research term of the agreement and selected by Indivior. 

Indivior  has  sole  responsibility,  including  funding  liability,  for  development  of  selected  compounds  under  the  agreement  through 
preclinical  and clinical trials, as  well as  registration procedures  and  commercialization,  if any,  worldwide.  Indivior has the  right  to 
design development programs for selected compounds under the agreement. Through the Group’s participation in a joint development 
committee,  the  Group  reviews,  in  an  advisory  capacity,  any  development  programs  designed  by  Indivior.  However,  Indivior  has 
authority over all aspects of the development of such selected compounds.  

Under terms of the agreement, the Group granted Indivior an exclusive license to use relevant patents and know-how in relation to 
the  development  and  commercialization  of  product  candidates  selected  by  Indivior.  Subject  to  agreed  conditions,  the  Group  and 
Indivior jointly own all intellectual property rights that are jointly developed and the Group or Indivior individually own all intellectual 
property rights that the Group or Indivior develop individually. The Group has retained the right to select compounds from the research 
program  for  further  development  in  areas  outside  the  interest  of  Indivior  including  Charcot-Marie-Tooth  type  1A  neuropathy,  or 
CMT1A,  Chronic  Cough  and  pain.  Under  certain  conditions,  but  subject  to  certain  consequences,  Indivior  may  terminate  the 
agreement. 

In January 2018, the Group received, under the terms of the agreement, a non-refundable upfront fee of USD 5.0 million for the right 
to use the clinical candidate, ADX71441, including all materials and know-how related to this clinical candidate. In addition, the Group 
is eligible for payments on successful achievement of pre-specified clinical, regulatory and commercial milestones totaling USD 330 
million and royalties on net sales of mid-single digits to low double-digits. 

On  February  14,  2019,  Indivior  terminated  the  development  of  their  selected  compound,  ADX71441.  Separately,  Indivior  funds 
research  at  the  Group,  based  on  a  research  plan  to  be  mutually  agreed  between  the  parties,  to  discover  novel  GABAB  PAM 
compounds. These future novel GABAB PAM compounds, if selected by Indivior, become licensed compounds. The Group agreed 
with Indivior to an initial research term of two years, which can be extended by twelve month increments and a minimum annual 
funding of USD 2 million for the Group’s R&D costs incurred. R&D costs are calculated based on the costs incurred in accordance 
with the contract. Following Indivior’s selection of one newly identified compound, the Group has the right to also select one additional 
newly identified compound. The Group is responsible for the funding of all development and commercialization costs of its selected 
compounds and Indivior has no rights to the Group’s selected compounds. The initial two-year research term was expected to run 
from May 2018 to April 2020. In 2019, Indivior agreed to an additional research funding of USD 1.6 million, for the research period. 
On October 30, 2020, the research term was extended until June 30, 2021 and Indivior agreed to additional research funding of USD 
2.8 million. Effective May 1, 2021, the research term was extended until July 31, 2022 and Indivior agreed additional research funding

of CHF 3.7 million, of which CHF 2.7 million has been paid to the Group and CHF 1.0 million paid directly by Indivior to third party 
suppliers that are supporting the funded research program. In August 2022, the research agreement was extended until March 31, 
2023 and Indivior agreed to additional research funding of CHF 0.85 million. The reserved indications, where Addex retains exclusive 
rights to develop its own independent GABAB PAM program, have also been expanded to include chronic cough. Effective November 
1, 2022, the research term was extended until June 30, 2023 and Indivior agreed to additional research funding of CHF 0.95 million.  

For the year ended December 31, 2022, the Group recognized CHF1.4 million as revenue (2021: CHF 2.9 million) and recorded a 
combined amount of CHF 0.4 million in contract asset and trade receivable as of December 31, 2022 (December 31, 2021: CHF 0.2 
million). 

Janssen Pharmaceuticals Inc. (formerly Ortho-McNeil-Janssen Pharmaceuticals Inc.) 

On December 31, 2004, the Group entered into a research collaboration and license agreement with Janssen Pharmaceuticals Inc. 
(JPI). In accordance with this agreement, JPI has acquired an exclusive worldwide license to develop mGlu2 PAM compounds for 
the treatment of human health. The Group is eligible to receive up to EUR 109 million in success-based development and regulatory 
milestone, and low double-digit royalties on net sales. The Group considers these various milestones to be variable considerations 
as they are contingent upon achieving uncertain, future development stages and net sales. For this reason, the Group considers the 
achievement of the various milestones as binary events that will be recognized as revenue upon occurrence.  

No amounts have been recognized under this agreement in 2022 and 2021.  

15.  Other income 

Under a grant agreement with Eurostars/Innosuisse the Group is required to complete specific research activities within a defined 
period of time. The Group’s funding is fixed and received based on the satisfactory completion of the agreed research activities and 
incurring the related costs.  
The  Group  was  awarded  a grant by  Eurostars/Innosuisse  in  2019  for  CHF  0.5 million of  which  CHF  0.38 million  were  paid as  of 
December 31, 2022 and CHF 0.12 million in February 2023. As of December 31, 2022 the Group recognized CHF 0.12 million as 
other receivables (CHF 0.13 million as of December 31, 2021). For the year ended December 31, 2022, the amount recognized in 
other income is nil (CHF 0.2 million for the year ended December 31, 2021). 

The Group additionally recognized other income from IT consultancy agreements.

The  evolution  of  the  total  operating  costs  is  mainly  driven  by  external  research  and  development  expenses,  staff  costs,  D&O 
insurance, professional fees and other operating costs. 

During the year ended December 31, 2022, total operating costs increased by CHF 3.3 million compared to the year ended December 
31, 2021, primarily due to increased staff costs for CHF 2.3 million mainly due to higher share-based compensation costs. During the 
same  period,  the  external  research  and  development  costs  increased  by  CHF  1.0  million  primarily  due  to  dipraglurant  clinical 
development activities for CHF 0.4 million and discovery activities for CHF 0.6 million.

The Group has decided not to recognize any deferred income tax assets at December 31, 2022 or 2021. The key factors which have 
influenced management in arriving at this evaluation are the fact that the Group has not yet a history of making profits and product 
development remains at an early stage.  

The amount of deferred income tax assets that arises from sources other than tax losses carried forward and the amount of deferred 
income tax liabilities are insignificant compared to the unrecognized tax losses carried forward.  

The tax losses carried forward by the Group and their respective expiry dates are as follows: 

2022………………………………………………………. 
2023……………………………………………………….

Tax losses carried forward expiring in 2027 and 2028, have been increased by CHF 4.0 million and CHF 2.8 million respectively due 
to final tax returns for the fiscal years ended December 31, 2020 and 2021 received from Swiss tax administration in 2022.  

As of December 31, 2022, the unrecorded tax losses carried forward increased to CHF 275,156,180 (2021: CHF 206,534,151).  

19.  Retirement benefit obligations 

Apart from the social security plans fixed by the law, the Group sponsors an independent pension plan. The Group has contracted 
with Swiss Life for the provision of occupational benefits. All benefits in accordance with the regulations are reinsured in their entirety 
with Swiss Life within the framework of the corresponding contract. This pension solution fully reinsures the risks of disability, death 
and longevity with Swiss Life. Swiss Life invests the vested pension capital and provides a 100% capital and interest guarantee. The 
pension plan is entitled to an annual bonus from Swiss Life comprising the effective savings, risk and cost results. Although, as is the

case with many Swiss pension plans, the amount of ultimate pension benefit is not defined, certain legal obligations of the plan create 
constructive obligations on the employer to pay further contributions to fund an eventual deficit; this results in the plan nevertheless 
being accounted for as a defined benefit plan. All employees are covered by this plan, which is a defined benefit plan. Retirement 
benefits  are  based  on  contributions,  computed  as  a  percentage  of  salary,  adjusted  for  the  age  of  the  employee  and  shared 
approximately  46%  /  54%  by  employee  and  employer.  In  addition  to  retirement  benefits,  the  plans  provide  death  and  long-term 
disability benefits to its employees. Liabilities and assets are revised every year by an independent actuary. Assets are held in the 
insurance company. In accordance with IAS 19 (revised), plan assets have been estimated at fair market values and liabilities have 
been calculated according to the "projected unit credit" method. The Group recorded a pension benefit charge in 2022 of CHF 279,920 
(2021: CHF 114,353) as part of staff costs. 

Employment benefit obligations

As of December 31, 2022, the funded status had a surplus of CHF 0.2 million that has not been recorded as an asset in accordance 
with  the  asset  ceiling  rules  and  minimum  funding  requirements  whilst  they  were  in  a  shortfall  situation  of  CHF  1.3  million  as  of 
December 2021. The decrease of the present value of the defined benefit obligation is primarily due to the increase of the discount 
rate to 2.30% as of December 31, 2022 compared to 0.35% as of December 31, 2021.  

The amounts recognized in the statement of comprehensive loss are as follows:

As of the date of the preparation of these consolidated financial statements, the 2022 annual report of the pension fund has not yet 
been issued, and therefore the detailed structures and assets held at December 31, 2022, are not currently available for presentation.  
However, the detailed assets held at December 31, 2021, which were reported to the Group on May 3, 2022 by its plan administrator, 
are as follows:

The principal actuarial assumptions used were as follows:

0.35%

The following sensitivity analysis shows the impact of increasing or decreasing certain assumptions on the defined benefit obligation 
of the Swiss pension plan: 
- 

0.25% increase or decrease in the discount rate would lead to a decrease of 3.09% (2021: 3.93%) or an increase of 3.48% (2021: 
4.52%) in the defined benefit obligation. 
0.25% increase or decrease in the interest rate on retirement savings capital would lead to an increase of 1.06% (2021: 0.58%) 
or a decrease of 1.03% (2021: 0.52%) in the defined benefit obligation. 
0.25% increase or decrease in salaries would lead to an increase of 0.09% (2021: 0.01%) or a decrease of 0.09%(2021: no 
decrease) in the defined benefit obligation; and 
+/-1 year in the life expectancy would lead to an increase of 1.02% (2021: 1.63%) or a decrease of 1.07% (2021: 1.69%) in the 
defined benefit obligation. 

- 

- 

- 

The discount rate and life expectancy were identified as significant actuarial assumptions for the Swiss pension plan. 

The above sensitivity analyses are based on a change in an assumption while holding all other assumptions constant. In practice, 
this is unlikely to occur, and changes in some of the assumptions may be correlated. When calculating the sensitivity of the defined 
benefit obligations to significant actuarial assumptions the same method (present value of the defined benefit obligation calculated 
with the projected unit credit method at the end of the reporting period) has been applied as that used in calculating the pension

The evolution of the finance result is mainly driven by foreign exchange losses and gains on our U.S Dollar cash deposits due to the 
evolution of the exchange rate of U.S Dollar compared to the Swiss franc. Finance result was a net loss of CHF 0.3 million for the 
year ended December 31, 2022 whilst it was a net gain of CHF 0.2 million for the year ended December 31, 2021.  

21.  Loss per share 

Basic  and diluted  loss  per  share  is calculated  by dividing  the  loss  attributable to equity holders of  the  Company  by  the  weighted 
average number of shares in issue during the year excluding treasury shares.

2021 
(15,351,914)

(0.45) 

The Company has four categories of dilutive potential shares: treasury shares, equity sharing certificates (“ECSs”), share options and 
warrants which have been ignored in the calculation of the loss per share for the year ended December 31, 2022 and 2021, as they 
would be antidilutive.  

In addition to treasury shares, the total number of dilutive instruments as of December 31, 2022 is 30,874,670 (2021: 29,590,875) 
which consists of 777,000 ESOP, 5,866,898 warrants granted to investors on March 28, 2018 and 24,230,772 warrants granted to 
one investor (9,230,772 warrants on December 21, 2021 and 15,000,000 on July 26, 2022 respectively). As of December 31, 2021, 
dilutive instruments primarily consist of 198,750 ESCs, 8,615,885 ESOP, 5,866,898 warrants granted to investors on March 29, 2018, 
9,230,772  warrants  and  5,478,570  pre-funded  warrants  granted  to  one  investor  on  December  21,  2021.  These  options  could 
potentially dilute basic earnings per share in the future.

STATUTORY AUDITOR'S REPORT  

To the general meeting of Addex Therapeutics Ltd,Plan-les-Ouates 

Report on the Audit of the Consolidated Financial Statements 

Opinion 

We have audited the consolidated financial statements of Addex Therapeutics Ltd and its subsidiaries (the Group), which comprise 
the consolidated balance sheet as at  December 31, 2022, and the consolidated statement of comprehensive loss, consolidated 
statement of changes in equity and consolidated statement of cash flows for the year then ended, and notes to the consolidated 
financial statements, including a summary of significant accounting policies. 

In our opinion the accompanying consolidated financial statements (pages 28 to 55) give a true and fair view of the consolidated 
financial position of the Group as at December 31, 2022 and its consolidated financial performance and its consolidated cash flows 
for the year then ended in accordance with International Financial Reporting Standards (IFRS) and comply with Swiss law. 

Basis for Opinion 

We conducted our audit in accordance with Swiss law, International Standards on Auditing (ISAs) and Swiss Standards on Auditing 
(SA-CH). Our responsibilities under those provisions and standards are further described in the "Auditor’s Responsibilities for the 
Audit of the Consolidated Financial Statements" section of our report. We are independent of the Group in accordance with the 
provisions of Swiss law, together with the requirements of the Swiss audit profession, as well as those of the International Code of 
Ethics for Professional Accountants (including International Independence Standards) of the International Ethics Standards Board 
for Accountants (IESBA Code), and we have fulfilled our other ethical responsibilities in accordance with these requirements.  

We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our opinion. 

Material Uncertainty Related to Going Concern 

We draw attention to Note 4 in the consolidated financial statements, which indicates that the Group future viability is dependent 
on  its  ability  to  raise  additional  capital  through  public  or  private  financings  or  collaboration  agreements  to  finance  its  future 
operations. The Group expects that its existing cash and cash equivalents be sufficient to fund its operations and meet all of its 
obligations as they fall due, through the third quarter of 2023. As stated in Note 4, these events or conditions, along with other 
matters as set forth in Note 4, indicate that a material uncertainty exists that may cast significant doubt on the Company’s ability 
to continue as a going concern. Our opinion is not modified in respect of this matter. 

Key Audit Matters 

Key audit matters are those matters that, in our professional judgment, were of most significance in our audit of the consolidated 
financial statements of the current period. These matters were addressed in the context of our audit of the consolidated financial 
statements as a whole, and in forming our opinion thereon, and we do not provide a separate opinion on these matters.

Addex Therapeutics Annual Report 2022 │ Consolidated Financial Statements 

Key Audit Matter 

How the Key Audit Matter was addressed in the 
audit 

Deferred Strike Price Payment Plan (DSPPP): 

The Group has implemented a staff retention plan 
which includes a DSPPP which encourages Board 
Members, Executive Managers and employees to 
exercise their share options or equity sharing 
certificates and become shareholders of the 
Group by allowing the deferral of the obligation to 
pay the strike price until the earlier of the sale of 
the shares or 10 years. 

Shares received through the exercise of unvested 
share options are subject to sales restrictions 
reflecting the remaining vesting period of 
exercised equity incentive units. 

On 26 October 2022, options holder exercised 
their vested and unvested options under the 
DSPPP. 

This is a significant focus point due to the 
complexity, judgement and estimates involved in 
determining the proper accounting in accordance 
with IFRS 2 "Share-based Payment". 

Refer to note 13 - Share-based compensation. 

We obtained an understanding of the process and 
controls through discussion with members of 
management and observation of documents. 

We substantively tested a sample of exercise options 
which is the basis for the recognition of the new 
options plan. 

We read and assessed the deferred strike price 
payment agreement and evaluated the transaction 
within the framework of IFRS 2 to determine how to 
account for the option exercises and whether the 
transaction constitute a replacement grant which 
should be accounted for by applying the principles of 
modification accounting, rather than as a separate 
new award and cancellation of the unvested old 
options. 

We assessed management’s judgments and estimates 
and evaluated the Group’s models to determine the 
incremental fair value as the difference between the 
fair value of the replacement equity instruments and 
the net fair value of the cancelled equity 
instruments, at the date the replacement by using 
the assistance of our valuation expert. 

We consulted with our internal experts regarding the 
accounting treatment in accordance with IFRS.  

We verified whether the relating disclosure in note 13 
is accurate and complete. 

Other Information 

The board of directors is responsible for the other information. The other information comprises the information included in the 
annual report, but does not include the consolidated financial statements, the financial statements, the compensation report and 
our auditor’s reports thereon. 

Our opinion on the consolidated financial statements does not cover the other information and we do not express any form of 
assurance conclusion thereon.  

In connection with our audit of the consolidated financial statements, our responsibility is to read the other information and, in 
doing  so,  consider  whether  the  other  information  is  materially  inconsistent  with  the  consolidated  financial  statements,  or  our 
knowledge obtained in the audit or otherwise appears to be materially misstated. If, based on the work we have performed, we 
conclude that there is a material misstatement of this other information,we are required to report that fact. We have nothing to 
report in this regard.

Addex Therapeutics Annual Report 2022 │ Consolidated Financial Statements 

Responsibilities of the Board of Directors for the Consolidated Financial Statements 

The board of directors is responsible for the preparation of the consolidated financial statements, which give a true and fair view 
in  accordance  with  IFRS  and the  provisions  of  Swiss  law,  and  for  such  internal  control as  the  board  of  directors  determines  is 
necessary to enable the preparation of consolidated financial statements that are free from material misstatement, whether due 
to fraud or error.  

In preparing the consolidated financial statements, the board of directors is responsible for assessing the Group’s ability to 
continue as a going concern, disclosing, as applicable, matters related to going concern and using the going concern basis of 
accounting unless the board of directors either intends to liquidate the Group or to cease operations, or has no realistic 
alternative but to do so.  

Auditor’s Responsibilities for the Audit of the Consolidated Financial Statements 

Our objectives are to obtain reasonable assurance about whether the consolidated financial statements as a whole are free from 
material  misstatement,  whether  due  to  fraud  or  error,  and  to  issue  an  auditor’s  report  that  includes  our  opinion.  Reasonable 
assurance is a high level of assurance, but is not a guarantee that an audit conducted in accordance with Swiss law, ISAs and SA-
CH will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered 
material if, individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users taken 
on the basis of these consolidated financial statements. 

A  further  description  of  the  auditor’s  responsibilities  for  the  audit  of  the  consolidated  financial  statements  is  located  at 
EXPERTsuisse's website at: https://www.expertsuisse.ch/en/audit-report-for-ordinary-audits. This description forms part of our 
auditor’s report. 

Report on Other Legal and Regulatory Requirements 

In accordance with Art. 728a para. 1 item 3 CO and PS-CH 890, we confirm that an internal control system exists, which has been 
designed for the preparation of consolidated financial statements according to the instructions of the board of directors.  

We recommend that the consolidated financial statements submitted to you be approved.

16.  Uncertainties and ability to continue operations 

The company believes that it will be able to meet all its obligation for a further 12 months from the issuance date of the financial 
statements,  hence,  the  statutory  financial  statements  have  been  prepared  on  a  going  concern  basis.  Nevertheless,  it  exists  a 
substantial doubt about the company’s ability to continue as a going concern as the existing cash and cash equivalents of the Group 
at the issuance date of the statutory financial statements is sufficient to fund its operations and meet all of its obligations as they fall 
due through the third quarter of 2023. The future viability of the Group is dependent on its ability to raise additional capital through 
public or private financings or collaboration agreements to finance its future operations, which may be delayed due to reasons outside 
of the Group’s control including the COVID-19 pandemic and the Russia’s invasion of Ukraine. The sale of additional equity may 
dilute  existing  shareholders.  The  inability  to  obtain  funding,  as  and  when  needed,  would  have  a  negative  impact  on  the  Group’s 
financial condition and ability to pursue its business strategies. If the Group is unable to obtain the required funding to run its operations 
and  to  develop  and  commercialize  its  product  candidates,  the  Group  could  be  forced  to  delay,  reduce  or  stop  some  or  all  of  its 
research  and  development  programs  to  ensure it  remains solvent.  Management  continues  to  explore options  to  obtain  additional 
funding, including through collaborations with third parties related to the future potential development and/or commercialization of its 
product  candidates.  However,  there  is  no  assurance  that  the  Group  will  be  successful  in  raising  funds,  closing  collaboration 
agreements, obtaining sufficient funding on terms acceptable to the Group, or if at all, which could have a material adverse effect on 
the Group’s business, results of operations and financial condition. 

17.  Events after the balance sheet date 

Addex Therapeutics sold 3,742,506 treasury shares for a gross amount of CHF 1.2 million under the sale agency agreement with 
Kepler Cheuvreux between the closing date and the approval of these financial statements.

STATUTORY AUDITOR’S REPORT 

To the General Meeting of Addex Therapeutics Ltd, Plan-les-Ouates 

Report on the Audit of the Financial Statements 

Opinion 

We have audited the financial statements of Addex Therapeutics Ltd (the "Company"), which comprise the balance sheet as at 
December 31, 2022, and the statement of loss for the year then ended, and notes to the financial statements, including a summary 
of significant accounting policies. 

In  our  opinion  the  accompanying  financial  statements  (pages  60  to  66)  comply  with  Swiss  law  and  the  Company's  articles  of 
incorporation. 

Basis for Opinion 

We conducted our audit in accordance with Swiss law and Swiss Standards on Auditing (SA-CH). Our responsibilities under those 
provisions and standards are further described in the "Auditor’s Responsibilities for the Audit of the Financial Statements" section 
of our report. We are independent of the Company in accordance with the provisions of Swiss law and the requirements of the 
Swiss audit profession, and we have fulfilled our other ethical responsibilities in accordance with these requirements.  

We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our opinion. 

Material Uncertainty Related to Going Concern 

We draw attention to Note 16 in the financial statements, which indicates that the Group future viability is dependent on its ability 
to raise additional capital through public or private financings or collaboration agreements to finance its future operations. The 
Group expects that its existing cash and cash equivalents be sufficient to fund its operations and meet all of its obligations as they 
fall due, through the third quarter of 2023. As stated in Note 16, these events or conditions, along with other matters as set forth 
in Note 16, indicate that a material uncertainty exists that may cast significant doubt on the Company’s ability to continue as a 
going concern. Our opinion is not modified in respect of this matter. 

Key Audit Matters 

Key audit matters are those matters that, in our professional judgment, were of most significance in our audit of the financial 
statements of the current period. These matters were addressed in the context of our audit of the financial statements as a whole, 
and in forming our opinion thereon, and we do not provide a separate opinion on these matters.  

Page 67 of 70 

Addex Therapeutics Annual Report 2022 │Statutory Financial Statements 

Key Audit Matter 

How the Key Audit Matter was addressed in the 
audit 

We obtained an understanding of management’s overall 
process  for  valuing  loans  to  subsidiaries,  including  the 
related  internal  controls  to  address  the  risk  of  non-
recoverability of such loans and the recording of timely 
provisions, where applicable. 

We  evaluated  management’s  assessment  of  the 
recoverability  of  the  loans  and  resulting  provisions, 
which is based on the net asset value of its subsidiary. 

We  also  assessed  the  appropriateness  of  the  related 
disclosures. 

Valuation of the loans to subsidiaries 
The  Company  has  granted  loans  to  its  subsidiary 
Addex  Pharma  SA  for  a  total  gross  value  of 
CHF  236'396'139  and  has  recorded  a  corresponding 
provision of CHF 225'882'023. 

This  is  a  significant  focus  point  due  to  the 
loans  provided  by  Addex 
significance  of  the 
Therapeutics  Ltd  to  its  subsidiary  and  the  need  of 
management  estimates  for  the  assessment  of  the 
carrying  value  of  these  loans  in  the  financial 
statements which implies a high level of judgment. 

In  order  to determine  any  potential  impairment  of 
the  value  of  the  loans  granted  to  its  subsidiaries, 
management has assessed the financial strength (net 
asset value or NAV) of the subsidiaries. 

Refer to note 9 Other non-current assets - Loans to 
Group companies 

Other Information 

The board of directors is responsible for the other information. The other information comprises the information included in the 
annual report, but does not include the financial statements, the consolidated financial statements, the compensation report and 
our auditor’s reports thereon. 

Our  opinion  on  the  financial  statements  does  not  cover  the  other  information  and  we  do  not  express  any  form  of  assurance 
conclusion thereon.  

In  connection  with  our  audit  of  the  financial  statements,  our  responsibility  is  to  read  the  other  information  and,  in  doing  so, 
consider whether the other information is materially inconsistent with the financial statements, or our knowledge obtained in the 
audit or otherwise appears to be materially misstated. If, based on the work we have performed, we conclude that there is a 
material misstatement of this other information,we are required to report that fact. We have nothing to report in this regard. 

Responsibilities of the Board of Directors for the Financial Statements 

The board of directors is responsible for the preparation of the financial statements in accordance with the provisions of Swiss law 
and the Company's articles of incorporation, and for such internal control as the board of directors determines is necessary to 
enable the preparation of financial statements that are free from material misstatement, whether due to fraud or error.  

In preparing the financial statements, the board of directors is responsible for assessing the Company’s ability to continue as a 
going concern, disclosing, as applicable, matters related to going concern and using the going concern basis of accounting unless 
the board of directors either intends to liquidate the Company or to cease operations, or has no realistic alternative but to do so. 

Page 68 of 70 

Addex Therapeutics Annual Report 2022 │Statutory Financial Statements 

Auditor’s Responsibilities for the Audit of the Financial Statements 

Our  objectives  are  to  obtain  reasonable  assurance  about  whether  the  financial  statements  as  a  whole  are  free  from  material 
misstatement, whether due to fraud or error, and to issue an auditor’s report that includes our opinion. Reasonable assurance is 
a  high  level  of  assurance,  but  is  not  a  guarantee  that  an  audit  conducted  in  accordance  with  Swiss  law  and  SA-CH  will  always 
detect  a  material  misstatement  when  it  exists.  Misstatements  can  arise  from  fraud  or  error  and  are  considered  material  if, 
individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis 
of these financial statements. 

A further description of the auditor’s responsibilities for the audit of the financial statements is located at EXPERTsuisse's website 
at: https://www.expertsuisse.ch/en/audit-report-for-ordinary-audits. This description forms part of our auditor’s report. 

Report on Other Legal and Regulatory Requirements 

In accordance with Art. 728a para. 1 item 3 CO and PS-CH 890, we confirm that an internal control system exists, which has been 
designed for the preparation of financial statements according to the instructions of the board of directors.  

We recommend that the financial statements submitted to you be approved. 

We  draw  attention  to  the  fact  that  treasury  shares  have  been  subscribed  by  a  group  company  in  excess  of  10  percent  of  the 
share capital, which is in breach of Article 659 paragraph 2 of the Swiss Code of Obligations.

Forward Looking Statements 

These  materials  contain  forward-looking  statements  that  can  be  identified  by  terminology  such  as  “not  approvable”,  “continue”, 
“believes”, “believe”, “will”, “remained open to exploring”, “would”, “could”, or similar expressions, or by express or implied discussions 
regarding Addex Therapeutics, formerly known as, Addex Pharmaceuticals, its business, the potential approval of its products by 
regulatory authorities, or regarding potential future revenues from such products. Such forward-looking statements reflect the current 
views of Addex Therapeutics regarding future events, future economic performance or prospects, and, by their very nature, involve 
inherent risks and uncertainties, both general and specific, whether known or unknown, and/or any other factor that may materially 
differ from the plans, objectives, expectations, estimates and intentions expressed or implied in such forward-looking statements. 
Such may in particular, cause actual results with allosteric modulators of mGlu2, mGlu3, mGlu4, mGlu5, mGlu7, GABAB or other 
therapeutic  targets  to be  materially  different  from any  future  results,  performance  or  achievements expressed or  implied  by  such 
statements.  There  can  be  no  guarantee  that  allosteric  modulators  of  mGlu2,  mGlu3,  mGlu4,  mGlu5,  mGlu7,  GABAB  or  other 
therapeutics  targets  will  be  approved  for sale  in  any  market  or  by  any  regulatory  authority.  Nor can  there  be any  guarantee  that 
allosteric modulators of mGlu2, mGlu3, mGlu4, mGlu5, mGlu7, GABAB or other therapeutic targets will achieve any particular levels 
of revenue (if any) in the future. In particular, management’s expectations regarding allosteric modulators of mGlu2, mGlu3, mGlu4, 
mGlu5, mGlu7, GABAB or other therapeutic targets could be affected by, among other things, unexpected actions by our partners,
