Letter to Shareholders  

Dear Shareholders,  

We  have  made  substantial  progress  in  2020  across  our  portfolio  as  we  continue  to  focus  on  the  discovery  and  development  of 
allosteric modulator drug candidates for the treatment of neurological disorders. We now have three programs expected to initiate 
clinical trials in the first half of the year, as well as numerous other discovery programs expected to deliver drug candidates in 2021. 
From a financial perspective, we completed one of our long-term goals to become a US listed company with the listing of American 
Depositary Shares (ADSs) representing our ordinary shares on the Nasdaq Capital Market on 29 January 2020. 

Our  priority  remains  our  lead  drug  candidate,  dipraglurant  for  the  treatment  of  levodopa  induced  dyskinesia  associated  with 
Parkinson’s disease. We completed several important activities related to this registration program and expect to dose patients in a 
placebo-controlled Phase 2b/3 pivotal clinical trial in H1 2021. In parallel, we substantially completed the preparation for a Phase 2 
clinical study with dipraglurant in blepharospasm and expect to start dosing patients in H1 2021. Our third clinical program, ADX71149 
is being developed by our partner, Janssen Pharmaceuticals, Inc., a Johnson and Johnson company. In 2020, Janssen announced 
plans to start development in epilepsy with a phase 2a proof of concept clinical study is planned to start dosing patients in Q2 2021. 

Our  partnership  with  Indivior  was  a  continued  focus  of  our  discovery  team  in  2020  with  multiple  lead  series  of  novel  gamma-
aminobutyric acid subtype B receptor (“GABAB”) positive allosteric modulators (“PAMs”) entering clinical candidate selection phase 
in Q4 2020. We expect to deliver drug candidate by the end of 2021 for both Indivior to develop in addiction and for us to develop in 
Charcot-Marie-Tooth type 1A neuropathy. On 30 October 2020, we extended our research collaboration with Indivior and received 
additional  funding  of  $2.8  million,  bringing  total  research  funding  received  since  2018  to  $8.4  million,  demonstrating  their  strong 
commitment to our partnership. 

Our metabotropic glutamate receptor subtype 7 (“mGlu7”) negative allosteric modulators (“NAM”) program for post-traumatic stress 
disorder has made significant progress in 2020 with the delivery of multiple novel lead series of compounds. The program has received 
significant support in 2020 from our consortium partners under the DiSARM FEAR Eurostars grant award of €4.85 million, which we 
announced in 2019.  

On 11 January 2021, we completed a global offering raising gross proceeds of $11.5 million from the sale of new shares primarily in 
the form of American Depositary Shares on the Nasdaq Capital Market.  

We have made tremendous progress in a difficult year and would like to acknowledge and thank our employees, consultants 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 2020│Financial Review 

Financial Review  

The following review and discussion of the financial results for 2020 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 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 2020, our financial results are driven primarily by activities related to the development of dipraglurant for Parkinson’s disease 
levodopa-induced dyskinesia (“PD-LID”) and discovery activities related to our gamma-aminobutyric acid subtype B receptor (“GABAB 
”) positive allosteric modulators (“PAMs”) partnership with Indivior PLC (“Indivior”) 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, 2020, our headcount was 22.50 full 
time equivalents (FTEs) compared to 18.50 FTEs at December 31, 2019.Our average headcount increased to 22.20 FTEs in 2020 
compared to 16.70 in 2019. In addition to our headcount, we engaged a number of consultants and service providers to complement 
our internal resources. 

Research and development expenditure decreased to CHF 10.4 million and general and administrative expenses increased to CHF 
5.7 million. CHF 3.9 million has been recognized as income in the year and our net loss decreased to CHF 12.9 million. We ended 
the year with a cash position of CHF 18.7 million.

Income 
Income was CHF 3.9 million in 2020 compared to CHF 2.8 million in 2019. In 2020, the Group recognized CHF 3.6 million under the 
licensing and research agreement with Indivior. Other income primarily relates to amounts recognized under our Eurostars/Innosuisse 
grant award.  

Research and development expenses 
R&D expenses decreased by CHF 2.0 million to CHF 10.4 million in 2020, compared to CHF 12.4 million in 2019, primarily due to 
delays in starting certain clinical development activities due to the global coronavirus pandemic. 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 and leasehold improvements, costs of materials used in research, costs associated with renting and operating facilities 
and equipment, as well as fees paid to consultants, patent costs and 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 0.7 million to CHF 5.7 million in 2020, compared to CHF 5.0 million in 2019, mainly due to the 
increase of CHF 1.3 million relating to increased directors and officer’s liability insurance premiums following the Company’s listing 
on the Nasdaq Stock Market from January 29, 2020, partially offset by a decrease of CHF 0.5 million in audit and legal fees. 

Finance costs, net 
The finance costs, net increased by CHF 0.5 million to CHF 0.7 million in 2020, compared to CHF 0.2 million in 2019, mainly due to 
increased foreign exchange losses on U.S dollars cash deposits, as a consequence of a stronger Swiss francs.

Addex Therapeutics Annual Report 2020│Financial Review 

Net loss for the year 
The net loss for the 2020 financial year was CHF 12.9 million compared to CHF 14.8 million for 2019 primarily due to the decrease in 
R&D costs. Basic and diluted loss per share decreased to CHF 0.48 for 2020, compared to CHF 0.56 for 2019.   

Balance sheet & cash flows 

Cash and cash equivalents decreased to CHF 18.7 million at December 31, 2020, compared to CHF 31.5 million at December 31, 
2019. This decrease of CHF 12.8 million is mainly due to the net loss. The negative working capital movement of CHF 1.5 million 
primarily due to reduced payables and accruals is offset by non-cash items of CHF 1.5 million that mainly relate to the value of the 
share-based services. The net cash flow from financing activities is close to nil as the gross proceeds of CHF 0.7 million from the net 
sale of treasury shares has been offset by the principal element of lease payments and related costs of capital increases.  

Total shareholders’ equity has decreased to CHF 14.6 million at December 31, 2020 compared to CHF 25.5 million at December 31, 
2019. The decrease of CHF 10.9 million is primarily due to the net loss of the year of CHF 12.9 million partially offset by the gross 
proceeds of CHF 0.7 million from the sale of treasury shares and the fair value of the share-based compensation of CHF 1.2 million. 

Post balance sheet event  

On January 8, 2021, the Company increased its capital from CHF 32,848,635 to CHF 39,748,635 through the issue of 6,900,000 new 
registered shares out of authorized capital with a nominal value of CHF 1 each at an issue price of CHF1.46367. Of these new shares, 
6,750,000 are in the form of American Depositary Shares or ADSs listed on the Nasdaq Stock Market. The gross proceeds amount 
to CHF 10.1 million (USD 11.5 million). 

Shares and shareholders’ information 

At December 31, 2020, the Company had 32,848,635 (2019: 32,848,635) outstanding issued shares and a free float of approximately 
81.95%. Of the outstanding issued shares at December 31, 2020, 5,729,861 shares were held in treasury (at December 31, 2019: 
6,243,487 shares). The closing share price was CHF 1.99 at December 31, 2020 compared to CHF 1.64 at December 31, 2019 and 
the market capitalization was CHF 65.4 million compared to CHF 53.9 million, respectively. 

2021 outlook 

We  expect  to  start  the  pivotal  registration  study  with  dipraglurant  for  PD-LID  and  a  Phase  2  clinical  study  with  dipraglurant  for 
blepharospasm in the first half of 2021. We also expect our partner Janssen to start a Phase 2 clinical study for epilepsy. Furthermore, 
we expect to advance our discovery programs including our GABAB PAM program under our partnership with Indivior and mGlu7 
NAM  program  which  is  supported  by  a  grant  from  Eurostars/Innosuisse.  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.

for the financing or refinancing of such transactions; 
for the purpose of the participation of strategic partners (including in the event of a public tender offer) or for the purpose of an

shares; or 
for raising capital in a fast and flexible manner, which would not be achieved without the exclusion of the statutory pre-emptive 
rights of the existing shareholders

2.4.  Shares and participation certificates 

Addex has one class of shares, i.e. registered shares with a nominal value of CHF 1 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 our 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 2020. 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, 2020, the Company has no convertible or exchangeable bonds or loans outstanding. As of December 31, 2020, 
the Company has a total of 13,034,108 options that primarily include 6,768,460 Employee Share Option Plan (ESOP), 5,866,898 
warrants granted in connection with the capital increase  of March 18, 2018 and 198,750 Equity Sharing Certificates (ESCs). The 
ESOP and ESCs outstanding, are granted to non-Directors, Executive Management, employees or consultants of the Group. They 
vest over a four-year period and have a 1:1 subscription ratio, from five to ten-year expiration term and an exercise price between 
CHF 1.00 to CHF 3.00. 0.45 warrants outstanding, have been granted to investors in connection with the capital increase of March 
28, 2018, for each new share issued. Each warrant entitles the investor to subscribe (which may be exercised without any specific 
conditions) to one registered share at a price of CHF 3.43 during a seven -year period. For information on equity incentive plans, refer

Information and control instruments vis-à-vis the Executive Management 

The Board ensures that it receives sufficient information from the CEO and Executive Management to perform its supervisory duty 
and to make the decisions that are reserved to the Board. At each Board meeting the Board receives reports from the CEO and 
selected members of the Executive Management on the status of finance, business, research and development. These reports focus 
on the main risks and opportunities related to the Group. In addition, the Board is provided with a status report prior to each board 
meeting, a monthly finance report and other ad hoc reports on significant matters related to the Group’s operations. 

Furthermore, the Board receives unaudited annual and interim financial statements for all Group companies including consolidated 
financial statements for the Company. The Board receives a written report from the auditors on the results of the audit which includes 
any findings with respect to internal control risks arising as a result of their audit procedures. The auditors held two meetings with the 
Chairman during the 2020 audit process. Addex does not have an independent internal audit function. For further information on the

annual dividend, approval of the compensation of the Board and management pursuant to the Articles, decisions to discharge the 
members  of  the  Board  and  management  for  liability  for  matters  disclosed  to  the  shareholders’  meeting  and  the  ordering  of  an 
independent investigation into specific matters proposed to the shareholders’ meeting. 

A resolution passed at a shareholders’ meeting with a qualified majority of at least two-thirds of the votes represented and the absolute 
majority of the nominal share capital is required by law for: 
–  changes to the business purpose; 
– 
the creation of shares with privileged voting rights; 
– 
restrictions on the transferability of registered shares;

– 

the dissolution of the Company. 

Special quorum rules apply by law to a merger, demerger, or conversion of the Company. The introduction or abolition of any provision 
in the Articles introducing a majority greater than that required by law must be resolved in accordance with such greater majority. 

6.2.  Statutory quorums 

There is no provision in the Articles requiring a majority for shareholders’ resolutions beyond the majority requirements set out by 
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 
necessary, by the auditors. Furthermore, the Board is required to convene an extraordinary shareholders’ meeting if so requested in 
writing by holders of shares representing at least 10% of the share capital and who submit a petition specifying the item for the agenda 
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

Addex Therapeutics Annual Report 2020│Corporate Governance Report 

to put an item on the agenda has to be made at least 60 days prior to the meeting. Extraordinary shareholders’ meetings may be 
called as often as necessary, in particular in all cases required by law. 

A shareholders’ meeting is convened by publishing a notice in the Swiss Official Commercial Gazette (Feuille Officielle Suisse du 
Commerce/Schweizerisches Handelsamtsblatt) at least 20 days prior to such meeting. In addition, holders of shares may be informed 
by a letter sent to the address indicated in the share register. 

6.5.  Entries in the share register 

The  Board  determines  the  relevant  deadline  for  registration  in  the  share  register  giving  the  right  to  attend  and  to  vote  at  the 
shareholders’ meeting. Such deadline is published by Addex on the Company’s website, usually in connection with the publication of 
the  invitation  to  the  shareholders’  meeting  in  the  Swiss  Official  Commercial  Gazette.  The  registration  deadline  for  the  ordinary 
shareholders’ meeting will be determined and communicated prior to the end of May 2021. Addex has not enacted any rules on the 
granting of exceptions in relation to these deadlines. No exceptions were granted in 2020, and the Board does not anticipate granting 
any exceptions related to the shareholders’ meeting to be held in 2021. For further information on registration in the share register, 
please refer to section “Limitations on transferability of shares and nominee registration” on page 9.

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).  

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.  

7.2.  Clauses on changes of control 

Addex’ equity sharing certificate incentive plan and share option 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 they become exercisable with their remaining term being reduced proportionally.

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. 
PricewaterhouseCoopers SA, Geneva, Switzerland (“PwC”) held the function of auditors for the fiscal years from 2002 to 2019. On 
May 5, 2020, PwC declined to stand for re-election at the 2020 Annual General Meeting held on June 9, 2020. During this meeting,

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 this 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, namely to attend during those agenda points dealt 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 2020, the Chairman of the Board or Audit Committee met with the auditors four times to discuss the financial situation of the Group, 
the scope and the results of their 2019 year-end audit and their review of the half-year and the third quarter interim reports. In 2021, 
the Audit Committee of the Board met with the auditors two times to discuss the financial situation of the Group, the scope and the 
results of their 2020 year-end audit.

Addex Therapeutics Annual Report 2020│Compensation Report 

Compensation Report 

Overview 

This  Compensation  Report  provides  the  information  required  by  the  federal  Ordinance  against  excessive  compensation  in  listed 
companies ("Compensation Ordinance") (effective as of January 1, 2014). It also includes information required by section 5 of the 
Annex to the Directive on Information relating to Corporate Governance of the SIX Swiss Exchange (effective date January 2, 2020) 
and the Swiss Code of Best Practice for Corporate Governance (status August 28, 2014). 

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

Review and approval process 

The  Board  reviews  compensation  of  its  members  and  members  of  the  Executive  Management  annually  in  accordance  with  the 
Company’s  Compensation  Policy.  In  its  review  process  the  Board  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 or business model, 
the professional experience and areas of responsibility of the respective members. The Board of Directors may also consult relevant 
compensation surveys and bench marking reports. Based on its review, 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 member of the Board consists of fixed and variable elements. 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 equity incentive units (share options and equity sharing certificates). 
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. In addition, the Company reimburses members of the Board for out-of-pocket expenses incurred in relation to their services 
on an on-going basis upon presentation of the corresponding receipts. The most recent review of compensation for members of the 
Board took place in March 2020. For further information on the compensation for members of the Board, please refer to the section 
“Compensation of the Board in 2020" on page 21. 

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 performance. 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. At the beginning of each 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  goals.  Equity  incentive  units  are  granted  based  on  the  discretion  of  the  Board.  Variable  cash 
compensation paid to Executive Managers in 2020 includes bonus and consulting fees. 

Equity incentive plans 

The  purpose  of  the  Company’s  share  purchase,  share  option  and  equity  sharing  certificate  programs  (refer  to  note  14  of  the 
consolidated financial statements) is to provide members of the Board, Executive Management, employees and certain consultants 
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 Company, enhancing the value of the shares for the 
benefit of the shareholders of the Company and increasing the ability of the Company to attract and retain individuals of exceptional 
skill. In addition, these plans provide the Company with a mechanism to engage services for non-cash consideration. The grant of 
any share option or equity sharing certificate is at the discretion of the Board. Key factors considered by the Board in making grants 
of share options or equity sharing certificates are the amount of shareholder approved conditional capital, the benchmarking with 

Page 20 of 64 

 
 
 
 
 
 
 
 
 
 
 
 
 
Addex Therapeutics Annual Report 2020│Compensation Report 

other companies as well as individual performance. The strike price is determined by the Board and is primarily based on the closing 
price of the Company’s shares on the SIX Swiss Exchange on the grant date. The transfer of treasury shares under the share purchase 
plan to settle consulting services are based on predefined terms of the consulting contract. 

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 2020. 

The Company has not granted any loans, credits or guarantees to members of the Board or of the Executive Management in 2020. 

Compensation for the financial year under review (audited) 

Measurement basis for compensation 

Fixed cash compensation, variable cash compensation and shares acquired under the share purchase plan: accrual basis; 

The measurement basis for each component of compensation is described below: 
• 
•  Equity incentive units: fair value at the grant date in accordance with IFRS 2 valuation methodology; and

REPORT OF THE STATUTORY AUDITOR ON THE COMPENSATION REPORT 

To the General Meeting of 

Addex Therapeutics Ltd, Geneva 

We  have audited  the  compensation report (annual report pages  20  to  22) of Addex Therapeutics Ltd for  the year 
ended 31 December 2020. The audit was limited to the information provided under articles 14 –16 of the Ordinance 
against Excessive Compensation with respect to Listed Stock Companies (the Ordinance). 

Responsibility of the Board of Directors 

The Board of Directors is responsible for the preparation and overall fair presentation of the compensation report in 
accordance with Swiss law and the Ordinance against Excessive Compensation with respect to Listed Stock Companies. 
The Board of Directors is also responsible for designing the compensation system and defining individual compensation 
packages. 

Auditor's responsibility 

Our  responsibility  is  to  express  an  opinion  on  the  accompanying  compensation  report.  We  conducted  our  audit  in 
accordance with Swiss Auditing Standards. Those standards require that we comply with ethical requirements and 
plan and perform the audit to obtain reasonable assurance about whether the compensation report complies with 
Swiss law and articles 14 – 16 of the Ordinance.  

An audit involves performing procedures to obtain audit evidence on the disclosures made in the compensation report 
with regard to compensation, loans and credits in accordance with articles 14 – 16 of the Ordinance. The procedures 
selected depend on the auditor’s judgment, including the assessment of the risks of material misstatements in the 
compensation report, whether due to fraud or error. This audit also includes evaluating the reasonableness of the 
methods  applied  to  value  components  of  compensation,  as  well  as  assessing  the  overall  presentation  of  the 
compensation report. 

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

Opinion 

In our opinion, the compensation report of Addex Therapeutics Ltd for the year ended 31 December 2020 complies 
with Swiss law and articles 14 – 16 of the Ordinance.

Addex Therapeutics Annual Report 2020 │ Consolidated Financial Statements Notes 

Notes to the Consolidated Financial Statements 
for the years ended December 31, 2020 and 2019 
(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 with its principal business location in San Francisco, California, 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 9, 2021.  

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 2020 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, 
2020. The Group noted that these new or amended standards 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, 2021 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 2021.  

Other standards adopted by the Group prior to January 1, 2020 

On January 1, 2019, the Group adopted IFRS 16 Leases, which replaced IAS 17 Leases and related Interpretations, applied by the 
Group until December 31, 2018. The Group leases various offices and equipment, which are recorded as right-of-use assets and the 
corresponding liabilities on the balance sheet at the date at which the leased assets are available for use by the Group. 

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 

Page 29 of 64 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Addex Therapeutics Annual Report 2020 │ Consolidated Financial Statements Notes 

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,  which  is 
registered  in  Plan-Les-Ouates,  Switzerland,  Addex  Pharmaceuticals  Inc.,  which  is  registered  in  Delaware,  United  States  with  its 
principal business location in San Francisco, United States and Addex Pharmaceuticals France SAS which is registered in Archamps, 
France. 

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 cost’.  

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.

Addex Therapeutics Annual Report 2020 │ Consolidated Financial Statements Notes 

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 “receivables”. 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.  Receivables  are  included  in  other  current  assets  in  the 
balance sheet (see note 7). 

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. Receivables are derecognized when settled.  

The Company classifies a contract asset as a receivable when the Company’s right to consideration is unconditional. If the Company 
transfers control of goods or services to a customer before the customer pays consideration, the Company records either a contract 
asset  or  a  receivable  depending  on  the  nature  of  the  Company’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 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 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.

Addex Therapeutics Annual Report 2020 │ Consolidated Financial Statements Notes 

The Company 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.  

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 is 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 there are suitable deferred income tax liabilities, then 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 and 
changes in actuarial assumptions are recognized immediately in other comprehensive loss and past-service costs are recognized 
immediately in the statement of comprehensive loss. 

The liability recognized in the balance sheet in respect of defined benefit pension plans is the defined benefit obligation at the balance 
sheet date minus the fair value of the plan assets. 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 

Page 32 of 64 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Addex Therapeutics Annual Report 2020 │ Consolidated Financial Statements Notes 

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 
sheets. 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 

Page 33 of 64 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Addex Therapeutics Annual Report 2020 │ Consolidated Financial Statements Notes 

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 
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 of full termination of the lease with any difference recognized in the 
statement of comprehensive loss. The lease liability is then further adjusted to ensure its 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 2020, a 10% increase or decrease in the EUR/CHF 
exchange rate would have resulted in a CHF 4,064 (2019: CHF 19,920) decrease or increase in net loss and shareholders’ equity as 
at December 31, 2020, a 10% increase or decrease in the GBP/CHF exchange rate would have resulted in a CHF 14,723 (2019: 
CHF 12,489) decrease or increase in net loss and shareholders’ equity as at December 31, 2020 and a 10% increase or decrease in 
the USD/CHF  exchange rate  would have resulted  in a  CHF 644,865  (2019: CHF 972,596) increase or decrease in  net loss  and 

Page 34 of 64 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Addex Therapeutics Annual Report 2020 │ Consolidated Financial Statements Notes 

shareholders’ equity as at December 31, 2020. 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. The Company’s 
Swiss  francs  cash  holdings  are  subject  to  negative  interest  rates  at  certain  thresholds  defined  by  its  bank  counterparties.  A  10% 
increase or decrease in the interest rates charged by the counterparties would not have had a material impact on the net loss for the 
period.  

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, 2020 and 2019. 

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  receivables  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 maintains detailed financial forecasts and monitors 
actual results on a regular basis so that measures can be taken to ensure the Group remains solvent. 

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 March 18, 2020, the Group announced the suspension of the initiation 
of a placebo-controlled Phase 2b/3 pivotal clinical trial of dipraglurant in levodopa-induced dyskinesia associated with Parkinson’s 
disease (dipraglurant PD-LID). The Group decided to suspend the trial based on the inability of planned clinical trial sites in the United 
States to initiate the trial in full compliance with the Group’s planned clinical trial procedures including with respect to data reporting, 
data monitoring, and the recommendations of various health authorities that the infirm patients who would participate in the trial not 
risk being exposed to COVID-19 at clinical trial sites. Such sites have been and may continue to be required to focus their limited 
resources on matters unrelated to our planned clinical trial, thereby decreasing availability, in whole or in part, for services to our 
planned clinical trial. The Group will not be able to initiate the trial until these risks have been significantly reduced or remediated. 
Although the Group believes, based on current projections of the pandemic, that it will be able to initiate the trial in the first half of 
2021, the duration of the COVID-19 crisis is uncertain and, if the enumerated risks are not addressed, the Group may have to adjust 
its expectations as to trial initiation, including potentially initiating the trial later in 2021, in order to accommodate the foregoing factors. 
In addition, the COVID-19 pandemic may affect the operations of the FDA and other health authorities, which could result in delays 
of reviews and approvals, including with respect to dipraglurant and our other product candidates. Any such delays could increase 
the cost of our planned clinical trial and increase the uncertainty of receiving approval from the FDA for dipraglurant in PD-LID patients. 
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 2021 and thereafter cannot be 
reasonably predicted. However, based on the risk mitigation measures undertaken, the Group concluded that there is no material 
uncertainty that may cast a significant doubt upon the Group’s ability to continue as a going concern. 

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 15.

Addex Therapeutics Annual Report 2020 │ Consolidated Financial Statements Notes 

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 2020 would have been CHF 888,845 or CHF 1,390,306, respectively (2019: CHF 
1,239,680 or CHF 2,023,158, respectively). This is compared to the amount recognized as an expense in 2020 of CHF 1,176,413 
(2019: CHF 1,685,965). Additional information is disclosed in note 14. 

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 20.

The Group applies the IFRS 9 simplified approach to measuring expected credit losses (“ECL”), which uses a lifetime expected loss 
allowance for all trade receivables and contract assets. As of December 31, 2020, the receivables comprise of four non-governmental 
debtors whose combined outstanding balances are CHF 20,577 (five non-governmental debtors for CHF 88,075 as of December 31, 
2019). The Group has considered these customers to have a low risk of default based on historic loss rates and forward-looking 
information  on  macroeconomic  factors  affecting  the  ability  of  the  customers  to  settle  the  receivables.  As  a  result,  excepted  loss 
allowance has been deemed as nil as of December 31, 2020 and December 31, 2019. As of December 31, 2020, prepayments mainly 
relate to amounts paid to contract research organizations and deferred costs primarily relate to paid legal and auditor fees associated 
with the preparation of the capital increase executed on January 8, 2021.

All payables mature within 3 months. Accrued expenses primarily relate to R&D services from contract research organizations and 
consultants. The total payables and accruals have decreased at December 31, 2020 compared to December 31, 2019, mainly due 
to amounts payable related to the preparation of the dipraglurant PD-LID clinical study at December 31, 2019. The carrying amounts 
of payables do not materially differ from their fair values, due to their short-term nature.

On June 1, 2010, the Company established an equity incentive plan based on equity sharing certificates (“ESCs”) to provide incentives 
to directors, executives, 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 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

15. 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

Addex Therapeutics Annual Report 2020 │ Consolidated Financial Statements Notes 

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. 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, that 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. In 2020, the Group implemented improved systems to capture internal staff costs by project and consequently revised certain 
cost estimates. 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 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 an additional research funding of USD 
2.8 million. 

For the research activities, the Group recognized CHF 3.6 million for the year ended December 31, 2020 (2019: CHF 2.8 million) and 
recorded CHF 0.7 million as contract liability (2019: CHF 0.9 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 consideration 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 2020 and 2019.  

16. 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. 

In October 2019, the Group received CHF 380,184 from Eurostars/Innosuisse. For the year ended December 31, 2020, the Group 
has recognized CHF 244,298 as other income (CHF 49,405 for the year ended December 31, 2019). As at December 31, 2020, the 
Group recognized CHF 86,481 as short term deferred income in accordance with the grant conditions. As at December 31, 2019 the 
Group recognized CHF 165,389 and CHF 165,390 as short and long-term deferred income, respectively. 

In  2020,  the  Group  has  additionally  recognized  revenue  from  IT  consultancy  agreements  as  other  income  for  CHF  22,026  (CHF 
21,430 for the period ended December 31, 2019).

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

During the year ended December 31, 2020, external research and development costs decreased by CHF 2.4 million compared to the 
year ended December 31, 2019 primarily due to delays in starting certain clinical development activities due to the global coronavirus 
pandemic. During the same period, professional fees decreased by CHF 0.6 million primarily due to lower audit and legal fees which 
had been abnormally high in 2019 due to the preparation of the Company’s Nasdaq listing. Insurance costs increased by CHF 1.5 
million due to higher directors and officer’s liability insurance premiums following the Company’s Nasdaq listing on January 29, 2020.

The wages and salaries increased by CHF 0.5 million for the year ended December 31, 2020 compared to the same period in 2019, 
primarily due to an increase in the average number of full-time equivalent employees from 16.7 in 2019 to 22.2 in 2020.

The Federal act on Tax Reform and Old Age and Survivors’ Insurance is effective in Switzerland from January 1, 2020. As a result, 
the income tax rate for companies in Geneva decreased from 23.40% to 13.99%.  

The Group has revised certain 2019 comparative amounts in the above tax reconciliation table, which were netted against total tax 
losses not recognized as a deferred tax asset and therefore did not have any effect on the income tax expense and the 
consolidated balance sheet.

The Group has decided not to recognize any deferred income tax assets at December 31, 2020 or 2019. 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 arise 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: 

2020……………………………………………………… 
2021……………………………………………………… 
2022………………………………………………………

As of December 31, 2020, the unrecorded tax losses carried forward increased to CHF 183,370,289 (2019: CHF 189,517,835). On 
July 18, 2019, the swiss tax administration accepted to renew CHF 138,115,931 that expires on December 31, 2023.    

20. 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 2020 of CHF 220,559 
(2019: CHF 296,247) as part of staff costs. 
Employment benefit obligations  
The amounts recognized in the balance sheet are determined as follows:

As of the date of the preparation of these consolidated financial statements, the 2020 annual report of the pension fund has not yet 
been issued, and therefore the detailed structures and assets held at December 31, 2020, are not currently available for presentation. 
However, the detailed assets held at December 31, 2019, which were reported to the Group on by its plan administrator on May 19, 
2020, are as follows:

The principal actuarial assumptions used were as follows:

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 4.36% (2019: 4.47%) or an increase of 5.06% (2019: 
5.22%) in the defined benefit obligation. 
0.25% increase or decrease in the interest rate on retirement savings capital would lead to an increase of 0.63% (2019: 0.59%) 
or a decrease of 0.59% (2019: 0.53%) in the defined benefit obligation. 
0.25% increase or decrease in salaries would lead to an increase of 0.03% (2019: 0.03%) or a decrease of 0.02% (2019: 0.02%) 
in the defined benefit obligation; and

+/-1 year in the life expectancy would lead to an increase of 1.85% (2019: 1.86%) or a decrease of 1.92% (2019: 1.92%) 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 
liability recorded on consolidated balance sheets. 

The methods and types of assumptions used in preparing the sensitivity analysis did not change compared to the prior period. 

The estimated employer contributions to pension plans for the financial year 2021 amount to CHF 245,000. The following table shows 
the funding of the defined benefit pensions and actuarial adjustments on plan liabilities:

The  evolution  of  the  finance  costs  is  mainly  driven  by  foreign  exchange  losses  that  increased  by  CHF  0.5M  for  the  year  ended 
December 31, 2020 compared to the same period in 2019 due to the strengthening of the Swiss franc against the U.S dollar.  

22. 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 shares purchased by the Group and held as treasury shares.

(0.48) 

2019 
(14,780,604) 
26,428,269 
(0.56) 

The Company has three categories of dilutive potential shares as at December 31, 2020 and December 31, 2019: equity sharing 
certificates (“ESCs”), share options and warrants. As of December 31, 2020, and December 31, 2019, equity sharing certificates, 
share options and warrants have been ignored in the calculation of the loss per share, as they would be antidilutive. 

The total number of dilutive instruments as of December 31, 2020 is 13,034,108 ( 2019: 11,906,248) which primarily consists of 
198,750 ESCs, 6,768,460 ESOP and 5,866,898 warrants granted in connection with the capital increase of March 18, 2018 (2019:

198,750 ESCs, 5,540,600 ESOP and 5,866,898  warrants granted in connection with the capital increase of March 18, 2018). 
These options could potentially dilute basic earnings per share in the future.  

23. Commitments and contingencies 

Capital commitments 
As at December 31, 2020 and 2019, the Group has no contracted capital expenditure. 

Contingencies 
As part of the ordinary course of business, the Group is subject to contingent liabilities in respect of certain litigation. Currently, there 
is no outstanding litigation. 

24. Related party transactions 

Related parties include members of the Board of Directors and the Executive Management of the Group. The following transactions 
were carried out with related parties: 

Key management compensation 
Salaries, other short-term employee benefits and 
post-employment benefits……………………………… 
Consulting fees………………………………………….. 
Share-based compensation….………………………... 

2020

2019 

1,156,427 
364,535 
1,434,190 
2,955,152 

Salaries, other short-term employee benefits and post-employment benefits relate to members of the Board of Directors and Executive 
Management who are employed by the Group. Consulting fees primarily relate to Roger Mills, a member of the Executive Management 
who  delivers  his  services  to  the  Group  under  a  consulting  contract.  The  Group  has  a  net  payable  to  the  Board  of  Directors  and 
Executive Management of CHF 145,443 at December 31, 2020 (December 31, 2019: CHF 176,089). 

25. Events after the balance sheet date  

On January 8, 2021, Addex Therapeutics Ltd issued 6,900,000 registered shares, with a nominal value of CHF 1 each, at an issue 
price of CHF 1.46367. Out of the total new shares, 6,750,000 are in the form of American Depositary Shares, listed on the Nasdaq 
Stock Market. As a result, the Company’s share capital increased from CHF 32,848,635 to CHF 39,748,635. The gross proceeds 
amount to CHF 10.1 million (USD 11.5 million).

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  statement  of  financial  position  as  at  31  December  2020  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 24 to 50) give a true and fair view of the 
consolidated financial position of the Group as at 31 December 2020, 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 Auditing 
Standards.  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 and the requirements of the Swiss 
audit  profession,  as  well  as  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. 

Other 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. 

Key Audit Matter 

How our audit addressed the key audit matter 

Revenue from contract with customer: 
The Group has only one source of revenue from contract 
with customer which relates to the licensing & research 
agreement with Indivior PLC (the "Agreement"). 

Since  January  1,  2018  the  Group  has  implemented  the 
new financial reporting standards IFRS 15 Revenue from 
Contracts  with  Customers.  Under  this  standard,  the 
Group identifies the distinct performance obligations in 
a contract, uses the most likely method to determine the 
variable consideration for inclusion in the transaction of 
an  estimated  stand-alone  selling  price  and  recognizes 
the related revenue over time or at a point in time as 
the  performance  obligations  are  satisfied  and  control 
passes to the customer. 

The Group signed a contract extension in October 2020 
for an additional USD 2'800'000 compensation of the joint 
research  agreement  and  recognized  a  total  of  CHF 
3'612'819 in revenue during the year ended 31 December 
2020  related  to  the  on-going  research  collaboration 
agreement with Indivior. 

This is a significant focus point due to the significance of 
the  revenue  recognized,  the  complexity  of  the 
Agreement and the judgement involved in identifying the 
performance obligations and potential changes thereon 
as well as the allocation of the transaction price. 

Refer to note 16 Revenue from contract with customer. 

Other Information in the Annual Report  

We  obtained  an  understanding  of  the  process  and 
controls by meeting with members of management. 

We inquired of management concerning any changes to 
the  original  Agreement  which  could  affect  the 
judgement underlying revenue recognized in 2020. 

We read and assessed the contract extension signed to 
determine  whether  terms  that  may  affect  revenue 
recognition  were  identified  and  properly  considered, 
performance obligations were appropriately identified in 
the  Company’s  evaluation  of  the  accounting  for  the 
contracts,  and 
the 
revenue  was 
appropriate amounts and periods. 

recognized 

in 

We  assessed  management’s  judgments  and  evaluated 
the Company’s models, which included the detailed cost 
build-ups  of  the  underlying  services.  We  tested 
substantively  the  determination  of  the  costs  incurred 
which is the basis for the recognition of the transaction 
price. 

Additionally,  we  obtained  the  support  for  the  cash 
received  from  Indivior  in  2020  and  recalculated  the 
related contract liability recorded at 31 December 2020. 

The Board of Directors is responsible for the other information in the annual report. The other information comprises 
all information included in the annual report, but does not include the consolidated financial statements, the stand-
alone financial statements of the Company, remuneration report and our auditor’s reports thereon. 

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

Addex Therapeutics Annual Report 2020 │ Consolidated Financial Statements 

In  connection  with  our  audit  of  the  consolidated  financial  statements,  our  responsibility  is  to  read  the  other 
information in the annual report 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. 

Responsibility of the Board of Directors for the Consolidated Financial Statements 

The Board of Directors is responsible for the preparation of the consolidated financial statements that 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 Swiss Auditing Standards 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 our responsibilities for the audit of the consolidated financial statements is located at the 
website of EXPERTsuisse: http://expertsuisse.ch/en/audit-report-for-public-companies. This description forms part 
of our auditor’s report. 

Report on Other Legal and Regulatory Requirements 
In accordance with article 728a para. 1 item 3 CO and the Swiss Auditing Standard 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.

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

Report of the Statutory Auditor on the Financial Statements 

Opinion 

We have audited the financial statements of Addex Therapeutics Ltd (the "Company"), which comprise the balance 
sheet as at 31 December 2020 and the income statement and notes for the year then ended, including a summary of 
significant accounting policies. 

In  our  opinion  the  financial  statements  (pages  54  to  60)  as  at  31  December  2020  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 Auditing Standards. 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. 

Other Matter 

The financial statements of Addex Therapeutics Ltd for the year ended 31 December 2019 were audited by another 
auditor who expressed an unmodified opinion on those financial statements on 8 April 2020.

Report on Key Audit Matters based on the circular 1/2015 of the Federal Audit Oversight Authority  

Key audit matters are those matters that, in our professional judgement, 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. 

Key Audit Matter 

How our audit addressed the key audit matter 

Valuation of the loans to subsidiaries 
The Company has granted loans to a subsidiary for a total gross 
value  of  CHF  204'417'747  and  has  recorded  a  corresponding 
provision of CHF 179'394'718. 

This is a significant focus point due to the significance of the 
loans provided by Addex 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 
subsidiary. 

Refer  to  note  8.  Other  non-current  assets  -  Loans  to  Group 
companies 

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. 

reviewed  management’s  assessment  of 

We  have 
the 
recoverability  of  the  loans  and  resulting  provisions,  which  is 
based  on  the  financial  position  of  its  subsidiary  and  inquired 
with  management  about  events  that  could  affect  the  future 
performance and financial position of this subsidiary. 

We  also  assessed  the  appropriateness  of  the  related 
disclosures. 

Responsibility 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. 

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 Swiss Auditing Standards 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  our  responsibilities  for  the  audit  of  the  financial  statements  is  located  at  the  website  of 
EXPERTsuisse:  http://expertsuisse.ch/en/audit-report-for-public-companies.  This  description  forms  part  of  our 
auditor’s report.

Report on Other Legal Requirements 

In  accordance  with  article  728a  para.  1  item  3  CO  and  Swiss  Auditing  Standard  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  the  absence  of 
sufficient freely disposable equity and that the company holds treasury shares in excess of 10 percent of the share 
capital, which is in breach of Article 659 paragraph 1 of the Swiss Code of Obligations. 

Furthermore, we draw attention to the fact that half of the share capital and legal reserves are no longer covered 
(art 725 para.1 CO).

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, 
unexpected regulatory actions or delays or government regulation generally; unexpected clinical trial results, including unexpected 
new clinical data and unexpected additional analysis of existing clinical data; competition in general; government, industry and general 
public pricing pressures; the company’s ability to obtain or maintain patent or other proprietary intellectual property protection. Should 
one or more of these risks or uncertainties materialize, or should underlying assumptions prove incorrect, actual results may vary 
materially from those anticipated, believed, estimated or expected. Addex Therapeutics is providing the information in these materials 
as of this date and does not undertake any obligation to update any forward-looking statements contained in these materials as a 
result of new information, future events or otherwise, except as may be required by applicable laws.
