CORPORATE OVERVIEW

FINANCIAL PERFORMANCE

STRATEGIC PARTNERSHIPS We signed three new pharmaceutical partnerships and extended two existing collaborations in 2015:

€236.2 MILLION In March, we announced an extension of our initial two-year research collaboration with Merck & Co., Inc. to develop and commercialise Nanobodies directed towards an undisclosed voltage-gated ion channel. Merck & Co., Inc. will extend their funding to the end of September 2016.

CASH, CASH EQUIVALENTS, RESTRICTED CASH AND OTHER SHORT TERM INVESTMENTS

€24.8 MILLION In May, a research and option agreement was signed with Genzyme to explore the potential of a Nanobody targeting an ion channel that plays a role in multiple sclerosis, triggering an undisclosed exclusivity payment to Ablynx.

CASH INCOME FROM COLLABORATIONS

€100 MILLION In June, we signed an exclusive license agreement with Taisho Pharmaceuticals to develop and commercialise the anti-TNFα Nanobody, ozoralizumab, in Japan.

We received an upfront payment of US$3 million and we are entitled to receive development and commercial milestone payments plus royalties.

In July, we significantly expanded our immuno-oncology partnership with Merck & Co., Inc., which was originally signed in February 2014, to include up to 17 programmes with focus on multi-specific Nanobodies. As part of both the original and expansion agreements, we received €33 million in upfront payments and are entitled to receive up to €5.7 billion in future milestone payments, plus royalties.

In November, we entered into a drug discovery collaboration with Novo Nordisk to investigate multi-specific Nanobodies in an undisclosed indication. We received an upfront payment of €5 million early in 2016, and are entitled to receive €4 million in research funding during the initial three year research term of the collaboration and up to €182 million in potential milestones, plus royalties.

CORPORATE OVERVIEW

DEAR SHAREHOLDERS, COLLEAGUES AND BUSINESS PARTNERS, 2015 WAS A YEAR OF EXCELLENT PROGRESS ACROSS OUR ENTIRE BUSINESS. OUR NANOBODY-BASED DRUGS ADVANCED SUCCESSFULLY INTO THE LATER STAGES OF DEVELOPMENT AS WE STARTED A PHASE III STUDY AND THREE PHASE II STUDIES WHICH TOGETHER WILL INCLUDE A TOTAL OF OVER 900 PATIENTS WORLDWIDE. COLLABORATIONS TO EXPLOIT THE FULL POTENTIAL OF OUR NANOBODY TECHNOLOGY CONTINUE TO FORM A CRUCIAL PART OF OUR HYBRID BUSINESS MODEL AS WE SIGNED THREE NEW PHARMACEUTICAL PARTNERSHIPS AND EXTENDED TWO EXISTING COLLABORATIONS, FURTHER FUELLING OUR BROAD PRODUCT PIPELINE, WHICH NOW INCLUDES OVER 40 PROPRIETARY AND PARTNERED PROGRAMMES. WE ALSO SUCCESSFULLY PLACED €100 MILLION OF FIVE-YEAR CONVERTIBLE BONDS – A PARTICULARLY NOTEWORTHY ACHIEVEMENT IN THE EUROPEAN BIOTECH SECTOR – STRENGTHENING OUR BALANCE SHEET TO FACILITATE THE FINANCING AND EXECUTION OF OUR BUSINESS PLAN.

MATURING PRODUCT PIPELINE

results with caplacizumab, our anti-vWF Nanobody to treat acquired TTP, we are on track to file for conditional approval of caplacizumab in Europe in early 2017 with the first European launch possible in 2018. In parallel with the European regulatory filing preparations, the confirmatory, international Phase III HERCULES study with caplacizumab has been initiated to support a BLA filing in the United States in 2018. The publication of the Phase II TITAN study in The New England Journal of Medicine on 11 February 2016 was a major accomplishment and is another endorsement of the potential of caplacizumab in the treatment of acquired TTP. We are now defining the commercial infrastructure required to lead the commercialisation of caplacizumab ourselves in Europe and the United States and we will announce further details when these plans are finalised.

2015 was a year of outstanding execution with six Nanobodies now in late-stage clinical development.

We significantly expanded our clinical pipeline with the start of a Phase III study with caplacizumab, our first-in-class wholly-owned bivalent Nanobody to treat acquired TTP, as well as three Phase II studies with the anti-IL-6R Nanobody, ALX-0061, in RA and SLE, for which AbbVie has an option for an exclusive global license.

In less than 10 months, we completed recruitment of 345 patients in the Phase IIb RA combination study of ALX-0061 and we completed recruitment of 35 infants in the Phase I/IIa study of our wholly-owned, first-in-class trivalent Nanobody, ALX-0171, to treat RSV, a serious viral respiratory infection. This was the first trial in which a Nanobody was administered to infants by inhalation and could prove to be a very important validation for the platform as a whole, in the general area of inhaled therapeutics, as well as in this particularly challenging indication.

HYBRID BUSINESS MODEL CONTINUES TO FUEL THE PIPELINE It is our ambition to ensure that the unique advantages of our Nanobodies are widely exploited to develop differentiated and innovative medicines which have the potential to make a real difference to patients suffering from severe diseases. To achieve this goal, we are committed to a hybrid business model where we invest directly in our own programmes in specific areas as well as collaborating with pharmaceutical partners at all

PREPARING FOR OUR FIRST PRODUCT LAUNCH 2015 was also the year in which we expanded our expertise beyond R&D, as we began preparing for our first product launch. Following compelling Phase II TITAN

anticipate top line results from two Phase IIb studies with ALX-0061 in patients with RA and then we will await the decision by AbbVie on whether they wish to exercise their option to license this product in this indication. We also expect the initiation of up to four clinical studies by our collaborators (one of which already started early in 2016) which would trigger milestone payments to Ablynx.

stages of discovery and development. These partners are selected for their expertise and experience in certain therapeutic indications as well as having resources which help us advance programmes rapidly. During the past year we have again successfully delivered on this business strategy and initiated four new internal discovery programmes and some 10 new partnered programmes. We broadened our disease scope through partnering with Genzyme (in multiple sclerosis) and Novo Nordisk (in a disease indication that is of strategic importance to them). We significantly expanded our immuno-oncology agreement with Merck & Co., Inc., so that it now includes up to 17 Nanobody programmes for which the first bi-specific Nanobody has already achieved pre-clinical proof-of-concept in in vivo cancer models. We also delivered a breakthrough in our ion channel collaboration with Merck & Co., Inc., resulting in an extension of the research term to September 2016.

THANK YOU To conclude, we would like to thank all of our talented employees for their dedication to achieving our goals, our business partners for their enthusiasm and commitment, and our shareholders for supporting us in the creation of a unique European biotech company with, we believe, very significant potential.

Sincerely yours,

AN EXCITING YEAR AHEAD As we continue to develop and mature, our priorities and objectives remain focused on delivering new hope for patients and sustainable value to all our stakeholders.

We look forward to an exciting year with multiple potentially value-creating catalysts, including the results from the Phase I/IIa study with ALX-0171 in 53 infants who were hospitalised with an RSV infection. We also

NANOBODIES® – POWERFUL PLATFORM GENERATING POTENTIALLY INNOVATIVE MEDICINES

PLATFORM ADVANTAGES

ABLYNX’S NANOBODIES

Nanobodies are a novel class of proprietary therapeutic proteins based on singledomain antibody fragments that contain the unique structural and functional properties of naturally-occurring heavy chain only antibodies. Due to their small size and unique structure, Nanobodies are ideal building blocks for the generation of novel biological drugs with multiple advantages:

Mix and match Ability to bind multiple targets with one therapeutic Nanobody molecule. These therapeutic molecules may contain Nanobody building blocks combined with each other (up to 7), combined with other protein domains, or with other molecules or drugs.

Multi-specific (binding different targets; currently 2 bi-specific Nanobodies in the clinic), multivalent (binding identical targets; currently 2 Nanobodies in the clinic) and bi-paratopic (binding 2 different epitopes on the same target) Nanobody molecules have been successfully produced and their potential therapeutic effect demonstrated.

Multi-specific/multivalent Nanobodies that address multiple targets in a single drug molecule – flexible GS* linker lengths

Multiple delivery routes

Inhalation

Ocular

The robust nature and stability of Nanobodies allows administration through multiple delivery routes, including intravenous and subcutaneous injection (currently 5 Nanobodies in the clinic) and nebulisation directly into the respiratory tract (currently 1 Nanobody in the clinic), as well as potentially through the ocular route and orally for local treatment in the gut.

Oral-to topical

Able to bind and block challenging targets Nanobodies can interact with epitopes on targets which are hidden or shielded from the much larger conventional antibodies.

Functional selective Nanobodies have been generated against GPCRs as well as against ion-gated, ligand-gate and voltage-gated ion channels (multiple programmes on-going, both internally and with partners including Merck & Co., Inc., Novartis and Genzyme).

Albumin-binding Nanobody

Fc

Ability to customise the in vivo half-life of a Nanobody from a few hours to over 3 weeks to achieve the desired properties, such as the use in chronic versus acute indications. Ablynx’s proprietary half-life extension technology is based on a Nanobody that binds to human serum albumin, thereby increasing the in vivo serum half-life of the therapeutic molecule.

Two clinical proof-of-concepts have been achieved in patients with rheumatoid arthritis with two Nanobodies that incorporate this proprietary half-life extension technology.

Manufacturing

High-yield high-concentration, low-viscosity, microbial production

ANNUAL REPORT 2015 / ABLYNX

Nanobodies (including multi-specific, multivalent and bi-paratopic constructs) are encoded by single genes and are efficiently produced with high-yields in prokaryotic and eukaryotic hosts, including bacteria, yeast, and mammalian cells. They can be formulated at high concentrations and maintain low viscosity, enabling multiple routes of administration, including low volume injectables.

Acquired thrombotic thrombocytopenic purpura Life-threatening, ultra-rare, acute blood clotting disorder ×× Auto-immune disorder characterised by impaired activity of ADAMTS13 (<10% of that in normal plasma) ×× Impaired ADAMTS13 activity leaves ultra-large vWF multimers (UL-vWF) uncleaved ×× UL-vWFs bind to platelets, resulting in severe thrombocytopenia (very low platelet count), and micro-clot formation in the small blood vessels of vital organs ×× Leads to small blood vessel occlusion, tissue ischaemia and organ damage Incidence rate ×× Up to 11 patients per 1 million people Current standard of care ×× Daily plasma exchange plus immunosuppressive treatments High unmet need with no drug specifically approved for this indication ×× Mortality high (10-20%), with vast majority within 2 weeks post diagnosis ×× Approximately 36% of patients have a recurrence ×× Major morbidities after TTP episode, including vital organ damage ×× Impacts life expectancy and quality of life

There remains a high need for a therapeutic that immediately inhibits micro-clot formation in the acute phase of the disease. Caplacizumab has been developed to address that need. It has a unique mode of action by inhibiting the interaction between ultra-large vWF and platelets through binding with the A1 domain of vWF. It thereby immediately prevents platelet aggregation and the formation of micro-clots in the acute, critical phase of acquired TTP.

ANNUAL REPORT 2015 / ABLYNX

24.

CORPORATE OVERVIEW

Three aTTP experts describe the impact of the NEJM publication: “Despite the advances in immunosuppressive therapy, better plasma exchange, better supportive care, the 10% to 15% acute mortality in acquired TTP in an acute episode has not been impacted. I think caplacizumab has the potential to do that.”

“With this drug I can quickly control the patient’s symptoms. I can detach the platelet from the ultralarge von Willebrand Factor and not have the consequences or damage due to microthrombosis, giving me more time to treat the patient. That is fantastic. This is the reason why this paper is very much appreciated by the physician and the patient.”

Dr Flora Peyvandi University of Milan, Italy

“

“The importance of this paper is twofold. Firstly, it’s the method of action of the compound, which is really quite unique. It’s not associated with significant side effects. It doesn’t appear to be immunogenic.

The second important and probably the most important reason for this trial is that we’ve always been stuck in the acute scenario of trying to achieve a rapid increase in the platelet count, which in itself is associated with a better outcome for patients, and that’s exactly what’s been demonstrated in this paper.”

“

“

“

“

Caplacizumab’s effect has been demonstrated in a worldwide, Phase II TITAN study in 75 patients with acquired TTP. Recently published in The New England Journal of Medicine: • Treatment with caplacizumab resulted in a nearly 40% reduction in median time to platelet count normalisation (p=0.005), reduced the use of daily plasma exchange, and prevented further consumption of platelets in the microclots and small blood vessel occlusion.

• Caplacizumab’s clinical effect has been shown by a low number of recurrences requiring re-initiation of daily plasma exchange during treatment with caplacizumab (N=3) versus placebo (N=11).

• Caplacizumab had an acceptable safety profile: manageable mild bleeding tendency; with no requirement for substitution therapy.

2015 achievements In August, the commercial strategy was defined whereby Ablynx retains full control over the commercialisation in Europe and the United States. In September, a confirmatory, international, Phase III HERCULES study of caplacizumab was initiated in patients with acquired TTP. Ablynx plans to recruit 92 patients into this study by 2017.

CORPORATE OVERVIEW

ALX-0171 has shown a potent anti-viral effect against a broad range of RSV strains and it demonstrated to have a strong therapeutic effect following administration via nebulisation in a neonatal animal model for infant RSV infection. Repeated daily inhalation of ALX-0171 was proven to be well-tolerated in multiple Phase I clinical studies in adult volunteers, including a study in subjects with hyper-reactive airways.

There remains a high need for an effective and specific therapeutic to treat RSV infections. ALX-0171 has been developed to address this unmet need and has firstin-class potential for the treatment of RSV infection. It is administered via nebulisation directly to the site of infection, i.e. the respiratory tract including the lungs, where it inhibits RSV replication and neutralises RSV activity by blocking virus uptake into cells.

2015 achievements In December, the Phase I/IIa safety study of inhaled ALX-0171 completed recruitment in 35 infants, aged 3-24 months, who were hospitalised with an RSV infection.

Also in December, an independent Data Monitoring Committee reviewed safety data available for the first 15 infants from the placebo-controlled part of this Phase I/IIa study and confirmed that the inclusion age for recruitment could be lowered to 1 month of age.

Post year-end, in January 2016, the Phase I/IIa study was expanded to include an expansion cohort of 18 additional infants, aged 1-5 months. Recruitment of this expansion cohort was completed ahead of schedule post year-end, in February 2016.

CORPORATE OVERVIEW

There remains a high need for new, differentiating treatment options with substantial efficacy. ALX-0061 has been developed to address this unmet need and the results from the Phase IIa study in 37 patients with RA demonstrated that ALX-0061 has best-in-class potential:

• Highly efficacious: treatment with ALX-0061 showed ACR20, ACR50 and ACR70 scores of up to 100%, 75% and 63% respectively, with first onset of activity as of week 2.

• Convenient dosing: wide therapeutic window with potential to dose subcutaneously once a month.

• Favourable safety profile: no dose dependent increase in frequency or severity of adverse events.

2015 achievements In March, Ablynx initiated a Phase IIb study of ALX-0061, in combination with methotrexate, in patients with RA. Recruitment of 345 patients was completed on schedule in December.

In April, Ablynx initiated a Phase IIb monotherapy study of ALX-0061 in RA patients. Recruitment of 251 patients was completed on schedule post year-end, in February 2016.

In July, the first eligible patients from the Phase IIb RA studies with ALX-0061 rolled-over into the open-label extension study.

In August, Ablynx initiated a Phase II study of ALX-0061 in patients with SLE. The Company plans to recruit 300 patients into this study by 2017.

CORPORATE OVERVIEW

KEY PRE-CLINICAL VALUE DRIVERS

IMMUNO-ONCOLOGY CHANGING THE CANCER TREATMENT PARADIGM • Extensive early-stage pipeline with Merck & Co., Inc., which includes up to 17 fullyfunded programmes • Multiple wholly-owned programmes in early development

WHY NANOBODIES? • Ideally suited to bind simultaneously to multiple different epitopes or targets with a single Nanobody construct • “Mix and match” approach allows for the rapid generation of multi-specific Nanobody constructs • Rapid exploration of combinations: in vivo proof-of-concept in 12-18 months • Multi-specific Nanobody combinations have the potential to increase efficacy and avoid escape mechanisms • Ease and cost-effective manufacturing • Further formatting flexibility: choice of half-life and potential to combine with Fc receptor

Extensive immuno-oncology collaboration with Merck & Co., Inc. In February 2014, Ablynx entered into a research collaboration and licensing agreement with a subsidiary of Merck & Co., Inc., focused on the discovery and development of 5 predefined Nanobody candidates (including multi-specific Nanobody combinations) directed toward so-called immune checkpoint modulators. In July 2015, Ablynx and Merck & Co., Inc. significantly expanded their collaboration to include up to 12 additional Nanobody programmes against individual protein targets and target combinations (mono-specific and multi-specific Nanobodies).

Under the terms of both the original and expansion agreements, Ablynx received €33 million in upfront payments and is potentially entitled to receive up to €5.7 billion in future development, regulatory and sales milestone payments, plus royalties.

Merck & Co., Inc. will be responsible for clinical development, manufacturing and commercialisation of any products resulting from the collaboration.

CORPORATE OVERVIEW

Immuno-oncology “Immuno” in immuno-oncology refers to a person’s own immune system. Immuno-oncology drugs, known as immunotherapies, target the patient’s own immune system to help fight cancer Cancer is the most common cause of death globally ×× Each year, approximately 14 million people are diagnosed with cancer ×× Approximately 8 million patients die of cancer each year ×× It is expected that in the next 2 decades the number of cancer cases will increase by 70% to approximately 22 million per year Current immuno-oncology treatment options ×× Immunotherapies have a proven substantial survival impact and are expected to treat 60% of cancers ×× First antibody drugs that hit the market target the immune checkpoint modulators CTLA4 and PD1 Next generation ×× The number of targets in immuno-oncology is increasing ×× Combination therapies are the next generation immunotherapies ×× Market in immuno-oncology drugs expected to grow to >US$43 billion by 2020

2015 achievements In July, Ablynx significantly expanded its immuno-oncology collaboration with Merck & Co., Inc., which was originally signed in February 2014, to include up to 12 additional programmes with focus on multi-specific Nanobodies. The expansion agreement triggered a €13 million upfront payment to Ablynx, comprising exclusivity fees and FTE payments.

In October, pre-clinical proof-of-concept was achieved with a bi-specific Nanobody programme as part of the immuno-oncology collaboration with Merck & Co., Inc. This Nanobody construct is a selective bi-specific molecule that potently binds to two different immune modulators. The results from the pre-clinical study in relevant tumour models demonstrated that this bi-specific Nanobody construct potently inhibits tumour growth.

Potential near term milestones 2016 - 2018 × Pre-clinical milestones (wholly-owned and with Merck & Co., Inc.)

× Start of clinical development with the first programme(s) both internally

and as part of the collaboration Merck & Co., Inc.

CORPORATE GOVERNANCE AND FINANCIAL INFORMATION

01. REPORT OF THE BOARD OF DIRECTORS

Dear Shareholders, We are pleased to present the financial statements for the fiscal year ended 31 December 2015 which have been prepared in accordance with the International Financial Reporting Standards (IFRS) as adopted by the EU.

1.1. STRATEGIC HIGHLIGHTS In 2015, total revenues and grant income increased by 57% to €77.5 million (2014: €49.3 million) driven by increased funding for full-time equivalents and increased recognised income, mainly from the upfront payment by AbbVie made in 2013. Total research and development costs increased to €83.1 million (2014: €54.5 million) in line with growth in external development costs, which are largely related to clinical trials expenditure for caplacizumab, ALX-0061 and ALX-0171. General and administrative costs remained broadly unchanged at €11.4 million (2014: €11.0 million). The operating loss increased to €17.0 million (2014: €16.2 million). The net loss for the period was €54.5 million (2014: €12.7 million). The net cash burn in 2015 (excluding the net proceeds of €97.2 million from the convertible bonds, announced on 20 May 2015) was €67.2 million. The Company ended the year with €236.2 million in cash, cash equivalents, restricted cash and other short-term investments.

Pipeline update At the end of 2015, there were five Nanobodies in clinical development, both internally and as part of collaborations.

In March 2015, Ablynx initiated a Phase IIb study of the anti-IL-6R Nanobody (ALX‑0061), in combination with methotrexate, in patients with rheumatoid arthritis (RA).

Recruitment of 345 patients was completed on schedule at year-end.

In April 2015, Ablynx initiated a Phase IIb monotherapy study of ALX-0061 in RA patients. Recruitment of 251 patients was completed in February 2016, also on schedule.

In July 2015, the first eligible patients from the Phase IIb RA studies with ALX-0061 rolled over into the open-label extension study.

In August 2015, Ablynx initiated a Phase II study with ALX-0061 in patients with systemic lupus erythematosus (SLE). The Company plans to recruit 300 patients in this study by 2017.

In September 2015, Ablynx initiated the confirmatory, international Phase III

ANNUAL REPORT 2015 / ABLYNX

CORPORATE GOVERNANCE AND FINANCIAL INFORMATION

HERCULES study of the anti-vWF Nanobody, caplacizumab, in patients with acquired TTP (aTTP). The Company plans to recruit 92 patients into this study by 2017. In February 2016, the Phase II TITAN study of caplacizumab was published in the New England Journal of Medicine.

In October 2015, pre-clinical proof-of-concept was achieved with a bi-specific Nanobody programme as part of the extensive immuno-oncology collaboration with Merck & Co., Inc., which triggered a €3.5 million milestone payment to Ablynx.

In November 2015, Ablynx's partner Boehringer Ingelheim presented compelling preclinical proof-of-mechanism data with the bi-specific anti-VEGF/Ang2 Nanobody in multiple in vivo cancer models. A Phase Ib study with this anti-VEGF/Ang2 Nanobody in patients with solid tumours was initiated by Boehringer Ingelheim in January 2016, triggering a €8 million milestone payment to Ablynx. Boehringer Ingelheim expects to recruit 80 patients in this study with top line efficacy results expected in 2018. In addition, a Phase II study with this Nanobody is expected to start in 2017, which would trigger a milestone payment to Ablynx.

In December 2015, the Phase I/IIa safety study with the inhaled anti-RSV Nanobody, ALX-0171, completed recruitment in 35 infants, aged 3-24 months, who were hospitalised with a respiratory syncytial virus (RSV) infection. Also in this month, an independent Data Monitoring Committee reviewed safety data available for the first 15 infants from the placebo-controlled part of this Phase I/IIa study and confirmed that the inclusion age for recruitment could be lowered to 1 month. The Company then decided to generate additional data during the current RSV season in the Northern Hemisphere by expanding the Phase I/IIa study to include up to 18 additional infants, aged 1-5 months. Recruitment of this expansion cohort was completed ahead of schedule in February 2016.

Partnerships update In March 2015, Ablynx announced an extension of its initial two-year research collaboration with Merck & Co., Inc. to develop and commercialise Nanobodies directed towards an undisclosed voltage gated ion channel. Merck & Co., Inc. extended their funding to the end of September 2016. This ion channel collaboration was announced in October 2012 and included a €6.5 million upfront payment and €2 million in initial research funding.

In May 2015, a research and option agreement was signed with Genzyme to explore the potential of a Nanobody targeting an ion channel that may play a role in multiple sclerosis, triggering an undisclosed exclusivity payment to Ablynx.

In June 2015, Ablynx and Taisho Pharmaceuticals signed an exclusive license

CORPORATE GOVERNANCE AND FINANCIAL INFORMATION

agreement to develop and commercialise the anti-TNFα Nanobody, ozoralizumab, in Japan. Ablynx received an upfront payment of US$3 million and is entitled to receive development and commercial milestone payments plus royalties.

In July 2015, Ablynx significantly expanded its immuno-oncology partnership with Merck & Co., Inc. which was originally signed in February 2014, to include a total of up to 17 programmes with a focus on multi-specific Nanobodies. As part of both the original and expansion agreements, Ablynx received €33 million in upfront payments and is entitled to receive up to €5.7 billion in future milestone payments, plus royalties.

In November 2015, Ablynx and Novo Nordisk entered into a drug discovery collaboration to investigate multi-specific Nanobodies in an undisclosed indication.

Ablynx received an upfront payment of €5 million in early 2016, and is entitled to receive €4 million in research funding during the initial three-year term of the collaboration and up to €182 million in potential milestones, plus royalties.

Corporate developments In November 2015, Ablynx announced that Dr Robert K. Zeldin had joined the Company as the new Chief Medical Officer (CMO), effective 1 December 2015, to lead the Company’s global clinical development, regulatory and medical affairs activities.

Dr Zeldin brings significant industry experience, having held senior level clinical development positions with Merck & Co., Inc. and Novartis Pharmaceuticals Corp. Dr Zeldin replaces Dr Dominique Tersago who previously held the CMO position.

1.2. ANALYSIS OF RESULTS OF OPERATIONS Total income Total revenues and grant income increased by 57% to €77.5 million (2014: €49.3 million), driven by increased FTE funding and increased recognised income, mainly from the upfront payment by AbbVie made in 2013.

Research and development expenses Total research and development costs increased to €83.1 million (2014: €54.5 million) in line with growth in external development costs, which are largely related to clinical trials expenditure for caplacizumab, ALX-0061 and ALX-0171.

CORPORATE GOVERNANCE AND FINANCIAL INFORMATION

General and administrative expenses General and administrative costs remained broadly unchanged at €11.4 million (2014: €11.0 million).

Operating result As a result of the foregoing, the operating loss increased to €17.0 million (2014: €16.2 million).

Net financial result The net financial loss of €37.6 million comprises finance income of €1.8 million, which relates to interest income and exchange gains, and finance costs of €39.4 million.

These finance costs mainly include non-cash expenditure resulting from the fair value calculation and amortisation of the convertible bond components (as a result of the higher share price at year-end compared to the share price at the time of the convertible bonds issuance), and the semi-annual interest paid on the convertible bonds of €1.6 million.

Net result As a result of the foregoing, the net loss for 2015 increased to €54.5 million (2014: €12.7 million).

Loss for the period As the Company incurred losses in all of the relevant periods, the Company had no taxable income and therefore paid no income taxes.

1.3. BALANCE SHEET ANALYSIS The Company’s intangible assets include a portfolio of patents, which are fully amortised, and technology licenses which are being amortised over 5, 18 and 20 years.

The intangible assets also include software licenses. The Company expenses all its research and development activities.

The Company’s non-current tangible assets include the Company’s laboratory and office equipment, the investments in its facilities, tax receivables and €1.6 million restricted cash, which is a cash pledge that the Company has provided for the lease of its headquarter building. The Company owns one small facility (which it previously rented) and continues to invest in equipment for its research activities. Non-current tax

CORPORATE GOVERNANCE AND FINANCIAL INFORMATION

receivables include an R&D tax credit receivable of €14.5 million.

The Company’s current assets of €246.1 million consist mainly of cash and cash equivalents and other short-term financial investments. Current tax receivables include an R&D tax receivable of €1.2 million.

Shareholders’ equity decreased from €75.5 million at the end of 2014 to €27.9 million at the end of 2015, mainly as a result of the incorporation of the loss for the period.

Non-current liabilities relate to the senior unsecured bonds due on 27 May 2020 with a principal value of €100 million.

Current liabilities consist mainly of trade payables and deferred income related to the upfront payments received from partners.

1.4. CASH FLOW ANALYSIS Cash flow from operating activities represented a net outflow of €69.0 million in 2015 compared to a net outflow of €32.3 million in 2014. The difference primarily relates to the higher number of clinical trials being run by the Company.

Cash flow from investing activities represented a net outflow of €39.7 million compared to a net outflow of €6.2 million in 2014. The net cash outflow comprises primarily the net movements in cash and cash equivalents (on deposit with a term of less than 1 month) and other short-term financial investments (on deposit with a term greater than 1 month).

Cash flow from financing activities represented a net inflow of €100.6 million compared to a net inflow of €39.7 million in 2014. The difference primarily relates to €97.2 million net proceeds from the issuance of convertible bonds and €5.2 million from the exercise of warrants.

The Company ended the period with a total liquidity position of €236.2 million (2014: €206.2 million) which consists of cash and cash equivalents of €3.6 million, other short-term financial investments of €231.0 million and restricted cash of €1.6 million.

1.5. OUTLOOK 2016 In the second quarter of 2016, the Company expects to report Phase I/IIa results from its study of the wholly-owned, inhaled anti-RSV Nanobody, ALX-0171, in 53 infants, who had been hospitalised with an RSV infection.

ANNUAL REPORT 2015 / ABLYNX

68.

CORPORATE GOVERNANCE AND FINANCIAL INFORMATION

In the first half of 2016, it is expected that the results will be announced from the Phase Ib study of the bi-specific anti-IL-17A/F Nanobody (ALX-0761), exclusively licensed to Merck KGaA (Merck Serono), in patients with moderate to severe psoriasis.

In the third quarter of 2016, the Company expects that the first patients from the Phase III HERCULES study of its wholly-owned anti-vWF Nanobody, caplacizumab, will have rolled-over into a three-year follow-up study to evaluate the long term safety and clinical effect of caplacizumab.

In the third quarter of 2016, Ablynx expects to communicate top line results from the monotherapy and combination therapy studies with the anti-IL-6R Nanobody, ALX‑0061, in patients with RA. Following a review of the complete RA data package, AbbVie is expected to decide before the end of 2016 whether it wishes to exercise its option to license ALX-0061 in RA. If AbbVie decides to exercise its option, Ablynx will receive a US$75 million milestone payment and AbbVie will then be responsible for providing all the resources to further develop and commercialise ALX-0061 in this indication. Ablynx will then be eligible to receive regulatory and sales milestones plus double-digit royalties.

In the fourth quarter of 2016, Ablynx intends to initiate a worldwide, Phase II dose ranging study with inhaled ALX-0171 in approximately 120 infants, aged 1-24 months, who are hospitalised with an RSV infection.

During 2016, the Company expects that up to 4 new partnered programmes could enter the clinic (Boehringer Ingelheim already started a Phase Ib trial with the antiVEGF/Ang2 Nanobody in January 2016) and additional pre-clinical data with partners may be obtained, thereby triggering milestone payments to Ablynx.

The net cash burn for the full year 2016 is expected to be in the range of €65-75 million, not including the potential licensing payment of US$75 million by AbbVie for ALX-0061 in RA.

1.6. CORPORATE GOVERNANCE STATEMENT 1.6.1. REFERENCE CODE – COMPLY OR EXPLAIN The Corporate Governance of the Company has been organised pursuant to the Belgian Companies Code and the Company’s Articles of Association. The Company’s Corporate Governance Charter is available on the Ablynx website via the following link: http://www.ablynx.com/investors/corporate-governance/principles-codes-andguidelines/. The Company’s Corporate Governance Charter and this Corporate

ANNUAL REPORT 2015 / ABLYNX

69.

CORPORATE GOVERNANCE AND FINANCIAL INFORMATION

Governance Statement have been adopted in accordance with the recommendations set out in the Belgian Corporate Governance Code (the “CGC”) that was issued on 9 December 2004 by the Belgian Corporate Governance Committee and subsequently amended on 12 March 2009.

The Charter is regularly updated and the date of modification is mentioned each time.

The Company has opted for a two-tier governance structure. As a result, the governance structure of Ablynx is based on a distinction between: • The management of Ablynx (including the daily management), a task conducted by the Executive Committee (“Directiecomité”) within the meaning of Art. 524bis of the Belgian Companies Code and within the framework of the general strategy defined by, and under the supervision of the Board of Directors; and • The development of the general strategy of Ablynx, the supervision of the Executive Committee and the exercise of specific powers attributed by the Belgian Companies Code, the Company’s Articles of Association and the Company’s Corporate Governance Charter, which fall within the powers of the Board of Directors.

All transactions involving conflicts of interests were in line with the precisions of the Corporate Governance Charter and are listed in the annual report under point 1.12.

The Company’s Board of Directors complies with the Corporate Governance Charter (CGC), and believes that certain deviations from its provisions are justified in view of the Company’s particular situation. These deviations include the following: • Provision 2.1 CGC: gender diversity. Since the IPO, the Board was mainly composed of men. The Company commits to build a diverse list of candidates for new positions in the future.

• Provision 2.9 CGC: the Company has no Company Secretary. The CFO acts as Company Secretary with the assistance of external counsels.

• Provision 5.2 CGC: the Company has no overall formal internal auditor because of the size of the Company. However, the Audit Committee regularly evaluates the need for this function and/or commissions external parties to conduct specific internal audit missions and report back to the Audit Committee.

• Provision 7.7 CGC: only the independent Directors shall receive a fixed remuneration in consideration of their membership to the Board of Directors and their attendance in the meetings of the committees of which they are members.

In principle, they will not receive any performance-related remuneration, nor will any options or warrants be granted to them in their capacity as Director. However, upon recommendation of the Nomination and Remuneration Committee, the Board of Directors may propose to the Shareholders Meeting to deviate from that

principle in application of Art. 554 BCC, if, to the Board of Directors’ reasonable opinion, the granting of options or warrants would be necessary or useful to attract or retain independent Directors with the most relevant experience and expertise.

1.6.2. CAPITAL AND SHARES The following capital increases took place in 2015: On 19 January 2015, the Company issued 115,946 new shares in exchange for €909,426.07 as a result of the exercise of warrants by some employees and consultants of the Company. The par value and share premium amounted to €216,819.02 and €692,607.05 respectively.

On 16 March 2015, the Company issued 174,302 new shares in exchange for €1,292,682.18 as a result of the exercise of warrants by some employees and consultants of the Company. The par value and share premium amounted to €325,944.74 and €966,737.44 respectively.

On 17 April 2015, the Company issued 20,165 new shares in exchange for €112,425.70 as a result of the exercise of warrants by some employees and consultants of the Company.

The par value and share premium amounted to €37,603.55 and €74,822.15 respectively.

On 27 May 2015, the Company raised €100 million through a private placement of €100 million senior unsecured bonds due 27 May 2020. The bonds were placed through an accelerated book building placement with qualified investors outside the United States, in accordance with Regulation S under the Securities Act. The bonds will mature on 27 May 2020 (5 years), are in dematerialised form in the denomination of €100,000 each, are issued at par and will be redeemed at par at maturity. The bonds will pay a coupon of 3.25% per annum, payable semi-annually in arrears on 27 November and 27 May of each year, beginning on 27 November 2015. The annual yield to maturity of the bonds is 3.25%. The initial price for the conversion of the bonds into ordinary shares of the Issuer shall be €12.93, representing approximately a 26.5% premium above the reference price of €10.2219, being the VWAP of the ordinary shares on Euronext Brussels on 20 May 2015. At the initial conversion price, the convertible bonds will be convertible into 7,733,952 fully paid-up ordinary shares of the Issuer. Conversion of the convertible bonds in Ablynx ordinary shares is at the option of the holder. In case of conversion: a cash alternative election (at the option of the issuer) is available including a number of restrictions. As the issuer has the cash alternative election, it has a choice over how the share conversion option will be settled (i.e. net in cash or by exchanging shares for cash).

Therefore the share conversion option is a derivative at Fair Value Through Profit and Loss (“FVTPL”) according to IAS 39, not an own equity instrument (cf. IAS 32.26).

CORPORATE GOVERNANCE AND FINANCIAL INFORMATION

1.6.4.2. ACTIVITY REPORT In 2015, seventeen Board meetings have been held.

In four of these meetings, the strategy and/or the company results have been discussed. All members of the Board were present at these meetings.

All other Board meetings were related to the exercise of warrants, the issuance of the convertible bond and the preparation of General Assemblies.

1.6.4.3. PERFORMANCE EVALUATION OF THE BOARD Under the lead of the Chairman, the Board regularly evaluates its performance to determine whether the Board and its Committees are functioning effectively. The evaluation process has the following objectives: assessing how the Board operates; verifying that important issues are adequately prepared and discussed; evaluating the actual composition of each Director’s work, the Director’s presence in the Board and Committee meetings and his/her constructive involvement in discussions and decisionmaking and verifying the Board’s current composition against the Board’s desired composition.

The non-executive Directors will assess their interactions with the Executive Committee. At least once a year, they meet in the absence of the CEO. No formal Board decision can be taken in such a meeting.

The Board has discussed its composition and performance on several occasions during 2015.

At the time of their re-election, the Directors’ commitments and contributions are evaluated within the Board, and the Board ensures that any appointment or re-election allows an appropriate balance of skills and experience to be maintained in the Board.

The same applies at the time of the appointment or the re-election of the Chairman (of the Board and of the Board’s Committees). The Board shall act on the results of the performance evaluation by recognising its strengths and addressing its weaknesses.

Where appropriate, this will involve proposing new members for appointment, proposing not to re-elect existing members or taking any measure deemed appropriate for the effective operation of the Board.

1.6.5. AUDIT COMMITTEE As of 8 January 2009 (the date on which the Law of 17 December 2008 with regard to the incorporation of an Audit Committee in listed companies and financial companies entered into effect), “large” listed companies (as defined in Art. 526bis of the Belgian Companies Code) are legally obliged to establish an Audit Committee within their Boards of Directors.

The Board of Directors has set up an Audit Committee. In 2015 the Audit Committee was composed of three members, which are exclusively non-executive Directors. All of its members are independent Directors and two of its members have an expertise in the field of accounts and audit. The Chairman of the Audit Committee is not the Chairman of the Board of Directors.

1.6.5.1. COMPOSITION The following Directors are members of the Audit Committee: Remi Vermeiren (Chairman), Dr Russell Greig, permanent representative of Greig Biotechnology Consulting Inc. and Catherine Moukheibir. Remi Vermeiren and Catherine Moukheibir have expertise in the field of accounts and audit and are both independent Directors.

1.6.5.2. ACTIVITY REPORT The Audit Committee met four times in 2015. During these meetings the financial results, budgets, treasury, topics related to risk management and the financial press releases were discussed.

The attendance was as follows: Remi Vermeiren (100 %), Dr Russell Greig (100%) and Catherine Moukheibir (75%).

The Audit Committee is responsible for the financial reporting, the internal control and risk management, the internal audit and the external audit, and for the reporting and communication between the statutory auditor and the Board. More detailed information on the responsibilities can be found on Ablynx’ website in the Corporate Governance Charter and in the Terms of Reference of the Audit Committee.

1.6.6. NOMINATION AND REMUNERATION COMMITTEE The Nomination and Remuneration Committee is appointed by the Board of Directors of Ablynx to advise the Board in its duties and responsibilities relating to the

ANNUAL REPORT 2015 / ABLYNX

82.

CORPORATE GOVERNANCE AND FINANCIAL INFORMATION

Nomination and the Compensation and Benefit programmes of executive & nonexecutive Directors, the Chief Executive Officer and the Executive Committee including other terms of employment for the CEO and the Executive Committee. The Nomination and Remuneration Committee at the same time reviews possible warrant plans for employees.

The basic principle is that the level of remuneration should be sufficient to attract, retain and motivate on each level the most talented individuals for the job.

1.6.6.1. COMPOSITION The Nomination and Remuneration Committee consists of three members: Greig Biotechnology Global Consulting Inc, represented by its permanent representative, Dr Russell Greig, William Jenkins Pharma Consulting, represented by its principal Dr William J. Jenkins, and Orfacare Consulting GmbH represented by its permanent representative Dr Bo Jesper Hansen.

These Directors are all members of Boards of other companies and as a result have broad knowledge of remuneration policies.

All members of the Nomination and Remuneration Committee are also a member of the Board of Directors.

All members are independent non-executive Directors. Each member of the Committee has appropriate knowledge and experience in compensation- and benefitrelated matters, since they are associates of Boards of other companies and as a result have knowledge of remuneration policies across the world.

The CEO and the Vice President Human Resources are invited to attend the meetings of the Nomination and Remuneration Committee in an advisory and nonvoting capacity on all matters. They do not attend discussions concerning their own remuneration.

The Chairman leads all meetings of the Committee, coordinates the evaluation of the performance of the CEO and acts as Secretary, although he can delegate this duty or parts thereof to the Vice President Human Resources.

The members of the Committee declare that they dedicate a significant amount of their time to the Committeeâ&#x20AC;&#x2122;s activities.

The Remuneration & Nomination Committee of Ablynx advises the Board of Directors on all aspects of the Compensation and Benefit programmes for the executive and

non-executive Directors, the CEO and the Executive Committee and other terms of employment for the CEO and the Executive Committee. The Committee makes recommendations to the Board on appropriate Compensation and Benefit programmes (in respect of both amounts and composition) of: • The CEO and the other members of the Executive Committee, upon proposal by the CEO (except when it concerns his own remuneration), such as: (i) the principal contractual terms and arrangements for the termination of employment; and (ii) the principal components of the remuneration package (including, the relative importance of each component, the performance criteria applying to the variable elements, the benefits in kind, bonuses and long-term incentives, whether stockrelated or not, in the form of stock options or other financial instruments); as well as Directors; • Drawing up the policy regarding warrant plans and overseeing the general policy for the granting of warrants to employees, executive and non-executive Directors and members of the Executive Committee. The CEO shall propose the identity of the beneficiaries and the number of warrants to be allocated to each of them (individually in the case of members of the Executive Committee, and individually or per category in the case of other Employees) to the Nomination and Remuneration Committee. The Nomination and Remuneration Committee shall evaluate such proposals. In the case of grants of warrants to the CEO, the initial proposal shall be made by the Committee itself.

• Ensuring that remuneration levels take into account risks involved, demands and time requirements of each role, and relevant industry benchmarks.

• Preparing the annual remuneration report.

• Explaining the remuneration report during the Statutory General Meeting.

As it is the Nomination and Remuneration Committee’s duty to oversee the search for appropriate candidates for appointment to the Executive Committee or non-executive Director membership to the Board of Directors, the Committee receives detailed and regular updates (while diligently respecting any confidentiality and conflict of interest issues) on the hiring of Executive Committee members from the CEO and is given the opportunity (or designated members) to interview the final candidate(s) before their appointment.

The Nomination & Remuneration Committee is, together with the Executive Committee, engaged in the Succession Planning of Executive Committee members, including the CEO. In the latter case the Nomination & Remuneration Committee coordinates closely with the Chairman any and all activities involved in planning for CEO succession.

Any recommendations made in respect of the recruitment or succession planning requires discussion and endorsement by the Board of Directors before becoming effective.

CORPORATE GOVERNANCE AND FINANCIAL INFORMATION

The Nomination & Remuneration Committee (or designated members) has the option to schedule exit interviews with departing members of the Executive Committee.

The Nomination & Remuneration Committee, with the input of the Executive Committee, annually reviews and presents the annual goals/objectives for the Board of Directors in order to finalise and approve the final goals and objectives by the Board of Directors.

The Nomination & Remuneration Committee also advises the Board of Directors on the accomplishment of the targets set earlier and consequently initiates a discussion on the Board which finally adjusts and/or approves the recommendations of the Nomination & Remuneration Committee.

1.6.6.2. ACTIVITY REPORT In 2015 the Nomination & Remuneration Committee officially met three times to fulfill its functions. Meeting minutes circulated after the meeting among all members of the Board of Directors.

During the meetings, the goals of the Company, the performance against the goals of the Company and the goals of the Executive Committee, the warrant plans, the salary evolution, the minutes of the previous meetings, the benchmark of salaries in general and more specifically of the Executive Committee members and the independent Directors and the nomination of new members of the Board of Directors were discussed.

On top of these meetings, the Nomination & Remuneration Committee held several teleconferences to discuss ad hoc nomination and remuneration topics.

1.6.7. THE RESEARCH AND DEVELOPMENT COMMITTEE The Research and Development Committee of the Board advises the Board on its duties and responsibilities related to the long term Research and Development strategy of the Company in general and the development of the Companyâ&#x20AC;&#x2122;s Nanobody platform and programmes in particular.

1.6.9. REMUNERATION REPORT

1.6.9.1. DIRECTORS Procedure applied in 2015 in order to create a remuneration policy and to determine the individual remuneration The Nomination and Remuneration Committee recommends the level of remuneration for Directors, including the Chairman of the Board, which is subject to approval by the Board and, subsequently, by the Annual Shareholders Meeting.

The Nomination and Remuneration Committee benchmarks the Directors’ compensation against peer companies to ensure competitiveness. Without prejudice to the powers granted by law to the Shareholders Meeting, the Board sets and revises at regular intervals the rules and the level of compensation for Directors executing a special mandate or having a seat in one of the committees, as well as the rules for reimbursement of the Directors’ business-related out-of-pocket expenses.

Apart from the remuneration for independent Directors, all Directors will be entitled to a reimbursement of out-of-pocket expenses actually incurred as a result of their participation in meetings of the Board of Directors.

The remuneration of the Directors will be disclosed to the Company’s shareholders in accordance with the applicable laws and regulations.

The level of remuneration should be sufficient to attract, retain and motivate Directors who match the profile determined by the Board.

Only independent Directors received a fixed remuneration in consideration of their membership of the Board and the Committees of which they are members. They have not received, any performance-related remuneration, nor have any options or warrants been granted to them.

Given the fact that the company acts in a highly competitive and international environment and is at the same time cost-conscious because it does not yet generate profits, the Board has — until the end of 2013 and upon advice of the Nomination and Remuneration Committee — proposed to the Shareholders Meeting to deviate from the latter principle and grant warrants in order to attract and retain highly qualified independent Directors.

The CEO as member of the Board did not receive any compensation for serving as member of the Board.

ANNUAL REPORT 2015 / ABLYNX

88.

CORPORATE GOVERNANCE AND FINANCIAL INFORMATION

Executive Committee members receive no additional compensation when invited to the Board.

The Directors’ mandate may be terminated ad nutum (at any time) without any form of compensation.

There are no employment or service agreements that provide for notice periods or indemnities between the Company and the members of the Board of Directors who are not a member of the Executive Committee. In respect of the members of the Board of Directors who are a member of the Executive Committee, reference is made to the section Executive Committee below.

Remuneration policy applied during 2015 During 2015 Ablynx obtained salary market data for the members of the Board via its own research.

The fixed annual remuneration of the Chairman of the Board is €100,000. No additional remuneration is foreseen for membership of other Board committees.

The fixed annual remuneration of independent Directors as part of their membership of the Board of Directors is €30,000, and the additional fixed annual remuneration of the Chairman of the Nomination and Remuneration Committee, the Chairman of the Audit Committee and the Chairman of the Research and Development Committee is €10,000.

For other independent non-executive Directors the additional fixed remuneration related to the membership of the Nomination and Remuneration Committee, the Audit Committee or the Research and Development Committee remains at €5,000 per committee.

With respect to the following two years, Ablynx does not foresee changes in its remuneration policy.

ANNUAL REPORT 2015 / ABLYNX

CORPORATE GOVERNANCE AND FINANCIAL INFORMATION

1.6.9.2. EXECUTIVE COMMITTEE Procedure applied in 2015 in order to create a remuneration policy and to determine the individual remuneration The remuneration of the members of the Executive Committee is determined by the Board of Directors upon recommendation of the Nomination and Remuneration Committee and subsequent to the CEO’s recommendation to this Committee (except for his own remuneration). Ablynx strives to be competitive in the European biotech market.

Remuneration policy applied during 2015 In the compensation strategy of Ablynx, the starting salary is primarily based on input from the market and the merit increase on individual performance. Via own research, Ablynx obtained mid 2015 salary market data for the members of the Executive Committee, in order to understand the compensation market. The data confirm the remuneration policy is in line with the market practice.

The level and structure of the remuneration of the members of the Executive Committee is such that qualified and expert professionals can be recruited, retained and motivated taking into account the nature and scope of their individual responsibilities.

An appropriate proportion of the remuneration package of a member of the Executive Committee shall be structured so as to link rewards to corporate and individual performances, thereby aligning on an annual basis the interests of a member of the Executive Committee with the interests of the Company and its shareholders.

Since any Short Term Compensation component should include a maximum award limit, an Executive Committee member can receive maximum 30% of the annual base remuneration as a performance-driven bonus. Given the competitive landscape, the CEO’s bonus will be maximum 50% of the annual base salary.

The Extraordinary General Meeting of 26 April 2012 has approved that the CEO’s variable remuneration, which is part of his yearly remuneration, will be spread over a period of one year. This means that the bonus is spread over a period that is shorter than the periods determined in Art. 520ter, second paragraph of the Belgian Companies Code. This deviation has been incorporated in Art. 25 bis of the Ablynx Articles of Association.

The corporate and individual goals are based on the operation performance of the Company as measured by a.o. financial indicators, progress in the pipeline, the

ANNUAL REPORT 2015 / ABLYNX

92.

CORPORATE GOVERNANCE AND FINANCIAL INFORMATION

completion and/or extension of important collaborations and other measures.

More specifically the following areas, not disclosed in great level of detail because of the competitive nature of the business, are part of the corporate goals and subsequently part of the individual goals of the members of the Executive Committee: • Control of the cash burn versus a predefined target; • Completion of new discovery deal(s) generating an upfront defined income; • Control of expenditure of internal development programs while delivering on time and against earlier agreed standards; • Initiation of new internal discovery programmes and access to complementary technologies.

The above goals and the criteria for the variable remuneration of the CEO and members of the Executive Committee are in advance and explicitly spelled out in a software system, which automates the performance management and appraisal process at Ablynx and binds the Company and the individuals. The variable remuneration will only be paid when the KPIs are effectively met. The Remuneration Committee evaluates the performance and makes a proposal to the Board.

Schemes under which members of the Executive Committee are remunerated in shares, warrants or any other rights to acquire shares, shall be subject to prior shareholder approval by way of a resolution taken by the General Meeting of Shareholders (except for warrants issued under the authorised capital). The approval shall relate to the scheme itself and not to the grant to individuals of share-based benefits under the scheme. As a rule, plans issued until September 2015 stated that 25% of the warrants granted vested after 1 year, 2.08% vested additionally after each full month, however, vested warrants would in principle not be exercisable within less than three full calendar years.

From September 2015 new plans state that as a rule, 28% of the warrants will vest after 1 year from the date of the offer, 9% vest additionally after each full quarter, however vested warrants shall in principle not be exercisable within less than three full calendar years.

In order to avoid a subjective and discretionary benefit, the grant of warrants to Executive Committee members (similar to the grant to certain levels of employees) is based on a formula. Whereas the Short Term Incentive (bonus) is based on contributing to the corporate goals, the Long Term Incentive plan is based on the performance against the key responsibilities in the job description of the individual or group of individuals as well as based on the observed attitude versus the values of the Company. The outcome of this yearly evaluation can vary between 2 (low) and 10 (high) points. Based on the ultimate performance score between 6 and 10 points, based on the share price and the yearly base salary of the individual, the exact number of

ANNUAL REPORT 2015 / ABLYNX

93.

CORPORATE GOVERNANCE AND FINANCIAL INFORMATION

warrants is calculated (number of warrants= (yearly salary/grant price)*performance coefficient). A performance score below 6 does not qualify for a Long Term Incentive.

The CEO presents his proposal regarding performance against key responsibilities and values to the Nomination and Remuneration Committee, which submits a final proposal regarding the offering of warrants to members of the Executive Committee and the CEO to the Board of Directors which takes a final decision.

The remuneration policy for the Executive Committee shall at least include the main contractual terms including the main characteristics of pension schemes, termination arrangements and the key elements for determining the remuneration, including (i) the relative importance of each component of the remuneration, (ii) the performance criteria chosen for the variable elements and (iii) the fringe benefits.

In 2015 the total amount of remunerations and benefits paid to the CEO and the other members of the Executive Committee and to the persons they are represented by, amounted to â&#x201A;Ź2,261,942.97 (gross, excluding VAT and share-related payments), of which a detailed breakdown is shown in the table below: Total

The insurance plan, for which the above amounts have been paid, is a defined contribution plan for which 10â&#x20AC;&#x2030;% of the base salary is contributed on a yearly basis.

Given the nature of the contract of the Executive Committee members there is no liability for the Company regarding the defined interest rate or total benefit during or at the end of the collaboration.

With respect to the two financial years to come, Ablynx does not foresee changes in its remuneration policy regarding the Executive Committee.

Severance payments Currently, all members of the Executive Committee are employed on the basis of a service agreement, which can be terminated at any time provided that a previously determined term of notice is observed, which, at the Companyâ&#x20AC;&#x2122;s discretion, can be replaced by a corresponding termination allowance. No other termination remunerations are foreseen. All service agreements contain non-competition clauses, as well as confidentiality obligations and obligations relating to the transfer of intellectual property.

The Corporate Governance Charter requires that every contractual settlement agreed upon before or after 1 July 2009 concerning the remuneration of the CEO or any other member of the Executive Committee, clearly states that the amount of the exit remuneration, which is granted when the contract is prematurely terminated, should not exceed the basic and variable remuneration of twelve months. All existing contractual settlements reached with the CEO, or any other member of the Executive Committee, do not contain any exit remuneration higher than 12 months. Except for Dr Edwin Moses, who is entitled to an exit remuneration which is equal to one (1) time his fixed annual compensation, all other Executive Committee members (Mr Ottevaere, permanent representative of Woconsult BVBA, CFO; Dr Robert K Zeldin, CMO; Dr Antonin Rollet de Fougerolles; CSO; Mr Johan Heylen, CCO; Mr Gielen, VP HR and Mr Gerrit Franciscus Landolt, VP IP and Legal) are entitled to an exit remuneration of one quarter (1/4) of their fixed annual compensation.

Claw-back provisions There are no provisions allowing the Company to reclaim any variable remuneration paid to the executive management based on incorrect financial information.

Miscellaneous Furthermore the company has no intention to compensate in a subjective or discretionary manner.

1.6.10. MOST IMPORTANT CHARACTERISTICS OF THE COMPANY’S INTERNAL CONTROL SYSTEMS AND RISK MANAGEMENT The Executive Committee should lead the Company within the framework of prudent and effective control, which enables to assess and manage risks. The Executive Committee should develop and maintain adequate internal control systems so as to offer a reasonable assurance concerning the realisation of the goals, the reliability of the financial information, the observance of applicable laws and regulations and to enable the execution of internal control procedures. The Audit Committee assists the Board of Directors in the execution of its task to control the Executive Committee.

The Company has opted for a “two-tier” governance structure. As a result, the principal governance structure of Ablynx is based on a distinction between: • The management of Ablynx (including the daily management), a task conducted by the Executive Committee (“Directiecomité”) within the meaning of Art. 524bis of the Belgian Companies Code, within the framework of the general strategy defined by, and under the supervision of the Board; and • The development of the general strategy of Ablynx, the supervision of the Executive Committee and the exercise of specific powers attributed by the Belgian Companies Code, the Articles of Association and the Corporate Governance Charter which fall within the powers of the Board.

Control Environment The Executive Committee has organised the internal control environment, based upon “COSO’s internal Control-integrated Framework of 2013” which is monitored by the Audit Committee. The role of the Audit Committee is stipulated in the Corporate Governance Statement and in the terms of reference of the Audit Committee.

The Audit Committee decided not to create an internal audit role for the time being, since the scope of the business does not justify a full-time role.

The role of the Audit Committee shall be to assist the Board in fulfilling its monitoring responsibilities in respect of control in the broadest sense, including responsibilities for the financial reporting process, the system of internal control and risk management (including the Company’s process for monitoring compliance with laws and regulations) and the external audit process.

Risk analysis During 2015, the management of the Company assessed its operational risks and challenged and compared these with the COSO 2013 risk intelligence framework. Following this exercise, appropriate actions will be proposed to the Executive Committee.

The Company is potentially subject to the following inherent risks: • Nanobody-based drug candidates must undergo rigorous pre-clinical and clinical testing, the results of which are uncertain and could substantially delay or prevent the drug candidates from reaching the market.

• Delays in clinical trials are common and may have many causes. Such delays could result in increased costs and jeopardise or delay the Company’s ability to achieve regulatory approval and commence product sales as currently contemplated.

• The Company’s drug candidates may not obtain regulatory approval when expected, if at all, and even after obtaining approval; the drugs will be subject to ongoing regulation. To date, one of the Company’s drug candidates has reached the stage of submission or evaluation for regulatory approval.

• The Company has a history of operating losses and an accumulated deficit; the Company may never become profitable or may not be able to sustain profitability in subsequent periods.

• The Company is reliant on collaborative partners for the development and commercialisation of most of its existing and future drug candidates.

• The Company’s patents and other intellectual property rights may not adequately protect its products and drug candidates, which may impede the Company’s ability to compete effectively.

• The Company may infringe the patents or other intellectual property rights of others and may face patent or other intellectual property litigation, which may be costly and time consuming.

• The Company faces, and will continue to face, significant competition and rapid technological change, which could limit or eliminate the market opportunity for its products and drug candidates.

• The Company relies on outsourcing arrangements with third parties for some of its activities including manufacturing and clinical trials management.

• The Company may not have adequate insurance cover, particularly in connection with product liability risk.

• The commercial success of the Company will depend on attaining significant market acceptance of its drug candidates among physicians, patients, healthcare payers and the medical community. The Company has not yet commercialised any product.

• If the Company fails to attract and retain qualified personnel, it may be unable to successfully develop its technologies, conduct its clinical trials and commercialise drug candidates.

• The Company may need additional funding, which may not be available on acceptable terms when required, if at all.

• The revenue is generated by a limited number of clients.

• Tax legislation in Belgium might change over time.

• Fair value measurements that cannot be fully based on market parameters are based on judgment and could potentially affect the fair value estimation, including the embedded derivative linked to the convertible bond issued in May 2015.

CORPORATE GOVERNANCE AND FINANCIAL INFORMATION

Our financial risk management consists of: Liquidity risk management The Company makes use of term accounts and treasury notes. The maturities of the term deposits are limited to a maximum of one year.

The Company has €1.6 million restricted cash related to a cash pledge.

On 27 May 2015, the Company raised €100 million through a private placement of €100 million senior unsecured bonds due 27 May 2020. The bonds will mature on 27 May 2020 (5 years) and will pay a coupon of 3.25% payable semi-annually.

The convertible bonds are convertible in Ablynx ordinary shares at the option of the holder. In case of conversion: a cash alternative election (at the option of the issuer) is available including a number of restrictions. Because the issuer has the cash alternative election, it has a choice over how the share conversion option will be settled (i.e. net in cash or by exchanging shares for cash). Therefore the share conversion option is a derivative at Fair Value Through Profit and Loss (“FVTPL”) according to IAS 39 and not an own equity instrument (cf. IAS 32.26).

Interest rate risk As the Company has no other significant interest-bearing assets or liabilities, its income and operating cash flows are independent of changes in the market interest rates.

Credit risk The credit risk arises from outstanding transactions with customers. It is the Company’s policy to deal with creditworthy partners to avoid significant risk exposure. The trade receivables relate to a limited number of high-ranked international customers for whom there is no recent history of default. The credit risk is highly concentrated around a limited number of customers.

The financial institutions have credit ratings varying from A+, over A to A-.

Available liquidities are placed with several banks.

No cash credit lines were available.

Foreign exchange risk The Company has sales transactions from research and collaboration agreements denominated in USD and purchase transactions denominated in AUD, CAD, CHF, DKK, GBP, JPY, MXN, RUB, SEK and USD. The Company did not enter into any currency hedging arrangements in order to cover this risk.

1.6.12.1. BOEHRINGER INGELHEIM AGREEMENTS The Boehringer Ingelheim Alzheimer’s disease agreement signed in January 2007 states that in the event of a change of control over Ablynx, Boehringer Ingelheim is entitled to terminate the research (as a result of which each party is released from paying any research license fees and Ablynx is no longer entitled to the research license from Boehringer Ingelheim), and is no longer held to participate in joint committees or to share its development and commercialisation plans. This clause was approved by the Company’s Annual Shareholders Meeting held on 29 April 2010 in accordance with Art. 556 of the Belgian Company Code.

However, this clause is no longer applicable as the Company announced on 28 August 2014 that, following the termination of the Phase I study with BI 1034020 in Alzheimer’s disease, and after a full review of the programme, Boehringer Ingelheim (BI) decided not to move forward with the development of this anti-Abeta Nanobody, thereby ending the collaboration in Alzheimer’s disease that both companies entered into in January 2007.

Under the Boehringer Ingelheim Strategic Alliance agreement signed in September 2007, it is stated that in the event of a change of control over Ablynx, Boehringer Ingelheim is also entitled to terminate the research (without being released from the obligation to pay royalties on licensed products, if any) and is no longer held to participate in joint committees, to share its development and commercialisation plans or to start new programmes. However, Boehringer Ingelheim is entitled to continue the research independently, and Ablynx’ option to co-promotion rights expires. This clause was approved by the Extraordinary Shareholders Meeting of 12 October 2007 in accordance with Art. 556 of the Belgian Company Code. The Agreement was extended with two years in March 2012 and the same change of control clause was approved by the Company’s Annual Shareholders Meeting of 26 April 2012. On 21 August 2014 the agreement was extended one last time until 31 December 2014, being the end of the Discovery Term of this Agreement.

1.6.12.2. MERCK KGaA AGREEMENTS The Merck KGaA agreement signed in September 2008 states that a change of control may result automatically, in the case of early joint research and development programmes, in a full opt-out by Ablynx. In the event of further advanced joint research and development programmes, Merck KGaA may at its sole discretion invite the controlling shareholder of Ablynx to continue to contribute to such joint research and development programme. If Merck KGaA does not extend such invitation or if Ablynx's controlling shareholder does not accept such invitation, the change of control results in a full opt-out by Ablynx. This clause was approved by the Company’s Annual

ANNUAL REPORT 2015 / ABLYNX

102.

CORPORATE GOVERNANCE AND FINANCIAL INFORMATION

Shareholders Meeting held on 29 April 2010 in accordance with Art. 556 of the Belgian Company Code.

The Merck KGaA agreement signed in October 2010 states that (i) in the event of a change of control over Ablynx during the research term, Merck KGaA is entitled to terminate the programmes and to assume sole responsibility for further discovery, development and commercialisation; and (ii) in the event of a change of control over Ablynx (a) in respect of early programmes, Ablynx will be deemed to have exercised its opt-out right in full (if the first opt-out point had been reached; if the first opt-out point had not yet been reached, as of the time that the first opt-out point will have been reached); and (b) in respect of further advanced programmes, Ablynx will be deemed to have exercised its opt-out right under the agreement in full, provided that Merck KGaA, at its sole discretion, invites the new controlling shareholder of Ablynx to continue to contribute to such programme. If Merck KGaA does not extend such invitation or if Ablynx's new controlling shareholder does not accept such invitation, the change of control results in an opt-out in full by Ablynx (in which case, however, the entitlement to royalties will be replaced by an entitlement to a share of net income calculated according to the percentage of resources provided by Ablynx to a programme until the first commercial sale). The clauses under (ii) cease to have effect, on a programme-by-programme basis, as of the first commercial sale of a product resulting from a programme. This clause was approved by the Company’s Extraordinary General Meeting of Shareholders of 11 January 2011 in accordance with Art. 556 of the Belgian Company Code.

In November 2011, a third agreement with Merck KGaA was signed with the same change of control clause as mentioned above. This clause was approved by the Company’s Annual Shareholders Meeting held on 26 April 2012 in accordance with Art. 556 of the Belgian Company Code.

The Merck KGaA collaboration agreement which was signed in September 2013 states that in certain cases of change of control of the Company Merck KGaA is entitled at their option either to (i) proceed with the relevant collaboration, it being understood that Merck KGaA shall have the right to unilaterally decide upon the composition and the continued existence of the joint committees in respect of this collaboration agreement, or (ii) terminate the collaboration agreement and to oblige the Company to transfer all or parts of the ongoing programmes under this collaboration agreement, in which case the Company and Merck KGaA shall enter into separate agreements in respect of these programmes and Merck KGaA shall be exempted from further payments (without any right, however, to reimbursement by the Company). This clause was approved by the Company’s Extraordinary General Shareholders Meeting on 7 November 2013 in accordance with Art. 556 of the Belgian Company Code.

1.12. CONFLICTING INTERESTS OF DIRECTORS (ART. 523 OF

THE BELGIAN COMPANIES CODE) The Directors report that since the last General Meeting three decisions have been taken which fall within the provisions of Art. 523 of the Belgian Companies Code.

As required by Art. 523 of the Belgian Companies Code, the full minutes of said meeting of the Board of Directors relating to such conflict of interests are to be reproduced hereunder: Meeting of the Board of Directors of 26 March 2015 Mr Moses did not participate in the deliberations and resolution of the Board with respect to this item on the agenda.

Prior to the deliberation on this item, the other members of the Board acknowledge that they have been informed, in accordance with Art. 523 of the Belgian Companies Code, by e-mail dated 20 March 2015, of the declaration by Edwin Moses in respect of his conflict of interest in relation to this item on the agenda, as follows: â&#x20AC;&#x153;In accordance with Art. 523 of the Belgian Company Code, I wish to report that I am faced with a conflict of interest of a financial nature in respect of the proposed decision of the Board of Directors to grant discharge to the members of the Executive Committee.

The decision to grant discharge to the members of the Executive Committee entails in principle a lapse of the right of the Company to submit a liability claim against (the members of) the Executive Committee in respect of the actions or decisions (in their capacity as members) of the Executive Committee during the 2014 fiscal year.

As I am a member of the Executive Committee, the decision to grant discharge to the members of the Executive Committee entails a conflict of interest of a financial nature between the Company and myself: as a result of such decision, I will no longer be subject to such liability claims in respect of my function as a member of the Executive Committee in the 2014 fiscal year, while the Company loses the opportunity to claim against me and the other members of the Executive Committee, which may lead to potential negative financial consequences for the Company.

The exact amount of the financial impact on the Company of this decision cannot be determined at this time, as it cannot be known, at this time, whether the Company would wish, in the future, to assert any liability claim vis-Ă -vis myself or the Executive Committee and, if so, in what amount. The financial impact on the Company consists of the loss of this particular possibility.

ANNUAL REPORT 2015 / ABLYNX

CORPORATE GOVERNANCE AND FINANCIAL INFORMATION

However, I believe that the decision to grant discharge to the members of the Executive Committee is in the interest of the Company. Through such decision, the Company expresses its confidence in the members of the Executive Committee and offers such members a measure of security, which will allow the Company to attract and retain capable managers within the Company, as well as keep the current members of the Executive Committee motivated, committed and focused on their tasks.

The Company’s statutory auditor has been copied on this e-mail, thereby notifying him of this conflict of interest.”

The Board confirmed that the financial impact on the Company of the decision to grant discharge to the members of the Executive Committee cannot be determined at this time, but consists in the lapse of the right of the Company to submit a liability claim against the (members of the) Executive Committee.

The Board was of the opinion that the decision to grant discharge to the members of the Executive Committee is in the interest of the Company, because it expresses the confidence in the members of the Executive Committee, which will allow the Company to attract and retain capable managers.

The Board of Directors considered that the decision to grant discharge is in the interest of the Company, because it keeps the current members of the Executive Committee motivated, committed and focused on their tasks.

In that perspective, the Board declared that it believes that the decision to grant discharge to the members of the Executive Committee is in the interest of the Company.

After deliberation on the basis of the draft of the annual accounts and the annual report of the fiscal year 2014, which counts as “Annual Activity Report” as described in the Charter of the Executive Committee, the Board of Directors unanimously granted discharge to the members of the Executive Committee for 2014.

Meeting of the Board of Directors of 24 February 2016 Mr Moses did not participate in the deliberations and resolution of the Board with respect to this item on the agenda.

CORPORATE GOVERNANCE AND FINANCIAL INFORMATION

Prior to the deliberation on this item, the other members of the Board acknowledge that they have been informed, in accordance with Art. 523 of the Belgian Companies Code, by e-mail dated 22 February 2016, of the declaration by Edwin Moses in respect of his conflict of interest in relation to this item on the agenda, as follows: "Dear Mr. Vanhees and Board members, I write to you in my capacity as member of the Board of Directors (the “Board”) of Ablynx nv (the “Company”).

I refer to the meeting of the Board scheduled for 24 February 2016, which will resolve on the issue of warrants for the benefit of certain employees and consultants of the Company (the “Stock Option Plan”).

In accordance with Article 523 of the Belgian Company Code, I would like to report that I have a financial conflict of interest in respect of this agenda item. In my capacity of member of the Executive Committee of the Company, I am selected as one of the beneficiaries of the Stock Option Plan and will accordingly be offered a certain number of warrants.

However, I believe that the approval by the Board of the Stock Option Plan is in the interest of the Company, given the limited financial consequences for the Company (as the issue of the warrants shall have no immediate financial impact on the Company), as well as the purpose thereof.

The purpose of this Stock Option Plan is (i) to create a long-term incentive for the selected employees and consultants who are able to contribute substantially to the success and growth of the Company; (ii) to provide the Company with the necessary means to recruit and retain competent and experienced staff members; and (iii) to create a common interest between the selected participants on the one hand and the shareholders of the Company on the other, aimed at an increase in the value of the Company’s shares.

The consequences of the Stock Option Plan for the existing shareholders and warrant holders, and more in particular the dilution that would result from the exercise of all offered warrants, are clearly indicated in the special report of the Board in accordance with Article 583 of the Belgian Company Code."

Meeting of the Board of Directors of 25 March 2016 Mr Moses did not participate in the deliberations and resolution of the Board with respect to this item on the agenda.

CORPORATE GOVERNANCE AND FINANCIAL INFORMATION

Prior to the deliberation on this item, the other members of the Board acknowledge that they have been informed, in accordance with Art. 523 of the Belgian Companies Code, by e-mail dated 20 March 2016, of the declaration by Edwin Moses in respect of his conflict of interest in relation to this item on the agenda, as follows: “In accordance with Art. 523 of the Belgian Company Code, I wish to report that I am faced with a conflict of interest of a financial nature in respect of the proposed decision of the Board of Directors to grant discharge to the members of the Executive Committee.

The decision to grant discharge to the members of the Executive Committee entails in principle a lapse of the right of the Company to submit a liability claim against (the members of) the Executive Committee in respect of the actions or decisions (in their capacity as members) of the Executive Committee during the 2015 fiscal year.

As I am a member of the Executive Committee, the decision to grant discharge to the members of the Executive Committee entails a conflict of interest of a financial nature between the Company and myself: as a result of such decision, I will no longer be subject to such liability claims in respect of my function as a member of the Executive Committee in the 2015 fiscal year, while the Company loses the opportunity to claim against me and the other members of the Executive Committee, which may lead to potential negative financial consequences for the Company.

The exact amount of the financial impact on the Company of this decision cannot be determined at this time, as it cannot be known, at this time, whether the Company would wish, in the future, to assert any liability claim vis-à-vis myself or the Executive Committee and, if so, in what amount. The financial impact on the Company consists of the loss of this particular possibility.

However, I believe that the decision to grant discharge to the members of the Executive Committee is in the interest of the Company. Through such decision, the Company expresses its confidence in the members of the Executive Committee and offers such members a measure of security, which will allow the Company to attract and retain capable managers within the Company, as well as keep the current members of the Executive Committee motivated, committed and focused on their tasks.

The Company’s statutory auditor has been copied on this e-mail, thereby notifying him of this conflict of interest.”

The Board confirmed that the financial impact on the Company of the decision to grant discharge to the members of the Executive Committee cannot be determined at this time, but consists in the lapse of the right of the Company to submit a liability claim

against the (members of the) Executive Committee.

The Board was of the opinion that the decision to grant discharge to the members of the Executive Committee is in the interest of the Company, because it expresses the confidence in the members of the Executive Committee, which will allow the Company to attract and retain capable managers.

The Board of Directors considered that the decision to grant discharge is in the interest of the Company, because it keeps the current members of the Executive Committee motivated, committed and focused on their tasks.

1.14. JUSTIFICATION OF THE VALUATION RULES Ablynx, established in 2001, is a biotechnology company. For the further successful expansion of the research and development activities, the Company is, among others, dependent on sufficient financial funding, the results obtained from research and the Company’s capacity to obtain and maintain adequate protection of its intellectual property.

In addition, several clinical tests are planned in the next years, which will increase the operational costs. On the other hand, major commercial deals were closed which have already generated and which will generate important revenues as milestones have been achieved. In view of the above, the Company initiated an IPO on Euronext in November 2007 and raised €85.2 million and initiated an SPO on Euronext in March 2010 and raised €50 million.

ANNUAL REPORT 2015 / ABLYNX

113.

CORPORATE GOVERNANCE AND FINANCIAL INFORMATION

On 28 February 2013 the Company raised an additional €31.5 million through a private placement of new shares via an ABO (accelerated bookbuilding procedure).

In June 2014 the Company raised another €41.7 million through a private placement of new shares via an accelerated bookbuilding procedure.

In May 2015, Ablynx raised €100 million gross through the placement of 1,000 senior unsecured convertible bonds due 27 May 2020, with a 3.25% coupon rate and a conversion price of € 12.93, representing a 26.5% premium above reference price of €10.2219 being the VWAP (“Volume Weighted Average price”) of Ablynx's Ordinary Shares on the Brussels Stock Exchange on 20 May 2015. At the initial conversion price, the Convertible Bonds will be convertible into 7,733,952 fully paid up Ordinary Shares of Ablynx.

The cash position at 31 December 2015 of €236.2 million, which includes cash, other short-term investments, restricted cash and cash equivalents, will allow the Company to keep up with the financial obligations for at least the following 12 months.

Consequently, the annual accounts have been prepared on the assumption that the Company is a going concern.

The Company’s equity under IFRS amounted to €27.9 million at 31 December 2015.

Based on the projected cash burn for 2016 and the volatility of the share price which impacts the fair value of the embedded derivate of the convertible bond, the equity could substantially change. On the other hand the Company’s equity could be positively impacted by the licensing fee that would be paid by AbbVie if they decide to exercise their option to license ALX-0061 in RA, as well as the conversion of the bonds into equity.

1.15. APPROPRIATION OF RESULTS Ablynx nv ended the financial year 2015 with a net loss of €13,447,008.39.

The Board of Directors proposed to appropriate the loss of the year of €13,447,008.39 to retained losses, the latter amounting to €111,534,698.34.

This brings the total amount of retained losses to €124,981,706.73.

1.16. IMPORTANT EVENTS SUBSEQUENT TO THE ACCOUNTING

REFERENCE DATE On 21 January 2016, Ablynx announced the issuance of an additional 288,170 common shares in exchange for €1,192,292.70 as the result of the exercise of warrants by some

On 29 January 2016, Ablynx announced that Boehringer Ingelheim had administered the first dose in a Phase I dose escalation study with the half-life extended bi-specific anti-VEGF/Ang2 Nanobody in adult patients with advanced solid tumours, which triggered a €8 million milestone payment to Ablynx. The aim of the study is to evaluate the safety profile and dosing schedule for this Nanobody.

On 23 February 2016, Ablynx announced the issuance of an additional 7,521 common shares in exchange for €34,726.41 as the result of the exercise of warrants.

The duration of the warrants is 7 years as of the issue date of the warrants. The warrants can only be exercised when vested and as from the beginning of the fourth calendar year following the year in which the warrants were offered.

On 22 March 2016, Ablynx announced the issuance of an additional 210,741 common shares in exchange for € 740,375.82 as the result of the exercise of warrants.

As a result of this transaction, Ablynx now has 55,318,806 shares outstanding.

CORPORATE GOVERNANCE AND FINANCIAL INFORMATION

Statutory auditor’s responsibility Our responsibility is to express an opinion on these financial statements based on our audit. We conducted our audit in accordance with International Standards on Auditing (ISA). Those standards require that we comply with ethical requirements and plan and perform the audit to obtain reasonable assurance about whether the financial statements are free from material misstatement.

An audit involves performing procedures to obtain audit evidence about the amounts and disclosures in the financial statements. The procedures selected depend on the statutory auditor’s judgment, including the assessment of the risks of material misstatement of the financial statements, whether due to fraud or error. In making those risk assessments, the statutory auditor considers internal control relevant to the Company’s preparation and fair presentation of financial statements in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the company’s internal control. An audit also includes evaluating the appropriateness of accounting policies used and the reasonableness of accounting estimates made by the Board of Directors, as well as evaluating the overall presentation of the financial statements. We have obtained from the Company’s officials and the Board of Directors the explanations and information necessary for performing our audit.

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

Unqualified opinion In our opinion, the financial statements of Ablynx nv give a true and fair view of the Company’s net equity and financial position as of 31 December 2015, and of its results and its cash flows for the year then ended, in accordance with International Financial Reporting Standards as adopted by the European Union and with the legal and regulatory requirements applicable in Belgium.

On this basis, we make the following additional statement, which does not modify the scope of our opinion on the financial statements: • The Directors’ report on the financial statements includes the information required by law, is consistent with the financial statements and is free from material inconsistencies with the information that we became aware of during the performance of our mandate.

08. NOTES TO THE FINANCIAL STATEMENTS

8.1. GENERAL INFORMATION Ablynx is a biopharmaceutical company engaged in the development of Nanobodies, proprietary therapeutic proteins based on single-domain antibody fragments, which combine the advantages of conventional antibody drugs with some of the features of small-molecule drugs.

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

ANNUAL REPORT 2015 / ABLYNX

CORPORATE GOVERNANCE AND FINANCIAL INFORMATION

8.2.1. BASIS OF PREPARATION The financial statements have been prepared in accordance with the International Financial Reporting Standards (IFRS) as adopted by the European Union, IFRIC Interpretations and Belgian legal requirements applicable to the Company. The financial statements are presented in thousands of euro (unless stated otherwise). The financial statements for the financial year ended 31 December 2015 have been approved for issue by the Board of Directors on 25 March 2016.

The financial statements have been prepared under the assumption that the Company is a going concern and under the historical cost convention, as modified by the revaluation of available-for-sale financial assets, financial assets and financial liabilities (including derivative instruments) at fair value through profit or loss.

The preparation of financial statements in conformity with IFRS, as adopted by the EU, requires the use of certain critical accounting estimates. It also requires management to exercise its judgment in the process of applying the Company’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 8.4.

Changes in accounting policy and disclosures without impact for the company: Standards and interpretations applicable for the annual period beginning on 1 January 2015 • Improvements to IFRS (2011-2013) (applicable for annual periods beginning on or after 1 January 2015) • IFRIC 21 Levies (applicable for annual periods beginning on or after 17 June 2014) Standards and interpretations published, but not yet applicable for the annual period beginning on 1 January 2015 • IFRS 9 Financial Instruments and subsequent amendments (applicable for annual periods beginning on or after 1 January 2018, but not yet endorsed in the EU) • IFRS 15 Revenue from Contracts with Customers (applicable for annual periods beginning on or after 1 January 2018, but not yet endorsed in EU) • IFRS 16 Leases (applicable for annual periods beginning on or after 1 January 2019, but not yet endorsed in EU) • Improvements to IFRS (2010-2012) (applicable for annual periods beginning on or after 1 February 2015) • Improvements to IFRS (2012-2014) (applicable for annual periods beginning on or after 1 January 2016)

8.2.2. CONSOLIDATION SCOPE Ablynx controlled a sole 100%-owned subsidiary (Ablynx SA with registered offices in Rua do Campo Alegre 1021, 4150-180 Porto, Portugal) up until February 2014, the date on which the liquidation of the subsidiary was closed.

The financial statements of Ablynx nv are presented in euro and rounded to the nearest thousand.

8.2.3. SEGMENT REPORTING The Company operates as a single operating segment.

8.2.4. FOREIGN CURRENCY TRANSLATION Functional and presentation currency Items included in the financial statements are measured using the currency of the primary economic environment in which the entity operates (functional currency). The financial statements are presented in euro, which is the functional and presentation currency of the Company.

ANNUAL REPORT 2015 / ABLYNX

126.

CORPORATE GOVERNANCE AND FINANCIAL INFORMATION

Transactions and balances Foreign currency transactions are translated into the functional currency using the exchange rates prevailing at the dates of the transactions. Foreign exchange gains and losses resulting from the settlement of such transactions and from the translation at yearend exchange rates of monetary assets and liabilities denominated in foreign currencies are recognised in the income statement.

Changes in the fair value of monetary securities denominated in foreign currency classified as available-for-sale are analysed between translation differences resulting from changes in the amortised cost of the security and other changes in the carrying amount of the security. Translation differences related to changes in the amortised cost are recognised in profit or loss, and other changes in the carrying amount are recognised in other comprehensive income (OCI).

Translation differences on non-monetary financial assets and liabilities such as equities held at fair value through profit or loss are recognised in profit or loss as part of the fair value gain or loss.

The following foreign exchange rates have been used for the preparation of the accounts: 1 Euro = X foreign currency

8.2.5. REVENUE RECOGNITION The Company generates revenue from research collaboration agreements and from government grants.

The Company recognises revenue when the amount of revenue can be reliably measured, when it is probable that future economic benefits will flow to the entity and when specific criteria have been met for each of the Companyâ&#x20AC;&#x2122;s activities as described below. The Company bases its estimates on historical results, taking into consideration the type of customer, the type of transaction and the specifics of each arrangement.

Research collaboration agreements These research agreements typically contain license fees, non-refundable upfront access fees, research and development service fees and milestone payments. The revenue recognition policy for research projects can be summarised as follows:

ANNUAL REPORT 2015 / ABLYNX

127.

CORPORATE GOVERNANCE AND FINANCIAL INFORMATION

• License fees are recognised when the Company has fulfilled all conditions and obligations. The license fee will not be recognised if the amount cannot be reasonably estimated and if the payment is doubtful. As the Company has a continuing involvement during the license period, license fees are recognised rateably over the term of the agreement.

• Non-refundable upfront fees for access to prior research results and databases are recognised when earned, if the Company has no continuing performance obligations and all conditions and obligations are fulfilled (this means after the delivery of the required information). If the Company has continuing performance obligations towards the client, the fee will be recognised pro rata the costs incurred (with adjustment to the actual performance period at the end of the contract or at the actual termination date).

• Research and development service fees are recognised as revenue over the life of the research agreement as the required services are provided and costs are incurred. These services are usually in the form of a defined number of full-time equivalents (FTE) at a specified rate per FTE. • Commercial collaborations resulting in a reimbursement of research and development (R&D) costs are recognised as revenue as the related costs are incurred. The corresponding research and development expenses are included in research and development expenses in the consolidated financial statements.

• Milestone payments are recognised as revenue upon the achievement of the milestone, when all conditions attached have been fulfilled.

Deferred revenue represents amounts received prior to revenue being earned.

that they are intended to compensate, and when there is reasonable assurance the Company will comply with the conditions attached to the grants, but not prior to the formal grant approval. These grants are separately presented in the income statement as and included in the operating income.

8.2.7. INTANGIBLE FIXED ASSETS Internally generated intangible assets Research expenses are charged to the profit and loss statement as incurred.

Development costs are only capitalised if the following conditions are met: â&#x20AC;˘ the internally developed intangible asset is identifiable and controlled by the entity; â&#x20AC;˘ the asset will generate future economic benefits; â&#x20AC;˘ the development costs can be reliably measured.

At present, the current stage of development activities does not allow any capitalisation of intangible assets. The existing regulatory and clinical risks constitute an important uncertainty with respect to the capitalisation of development costs. In contrast to Belgian GAAP, the R&D expenses are not capitalised because the criteria under IFRS are not met.

As no internally generated assets are recognised, all costs with respect to the protection of intellectual property are expensed as R&D expenses.

Purchased intangible assets Acquired computer software licenses are capitalised on the basis of the costs incurred to acquire and bring to use the specific software. These costs are amortised on a straight-line basis over their estimated useful lives of maximum three years.

Acquired knowledge in the form of licenses and patents is recorded at cost less accumulated amortisation and impairment. It is amortised on a straight-line basis over the shorter of the term of the license agreement and its estimated useful life.

The Company does not have intangible fixed assets with an indefinite useful life.

8.2.8. PROPERTY, PLANT AND EQUIPMENT An item of property, plant and equipment is carried at historical cost less accumulated depreciation and impairment. Costs relating to the day-to-day servicing of the item are recognised in the income statement as incurred. Gains and losses on the disposal of

ANNUAL REPORT 2015 / ABLYNX

129.

CORPORATE GOVERNANCE AND FINANCIAL INFORMATION

property, plant and equipment are recognised in other income or expense.

A pro rata straight-line depreciation method is used to reflect the pattern in which the asset’s future economic benefits are expected to be consumed by the entity. However, land is not depreciated. The residual value and the useful life of an asset is reviewed each financial year-end for possible impairment. Depreciation is charged to the income statement on the following basis:

Buildings

10 year

Equipment

3 year

Hardware

3 year

Furniture

5 year

Equipment under leasing

The shorter of the useful life or the minimum leasing term

Leasehold improvements

The shorter of the useful life or the minimum leasing term

Property, plant and equipment under construction are not depreciated.

8.2.9. IMPAIRMENT OF NON-FINANCIAL ASSETS Assets that have an indefinite useful life are not subject to amortisation and are tested annually for impairment. Assets that are subject to amortisation or depreciation are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. An impairment loss is recognised 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). Non-financial assets other than goodwill that suffered impairment are reviewed for possible reversal of the impairment at each reporting date.

8.2.10. DERIVATIVE FINANCIAL INSTRUMENTS AND HEDGING ACTIVITIES The Company has no derivative financial instruments, in all material respect, to hedge interest rates and foreign currency risks.

ANNUAL REPORT 2015 / ABLYNX

130.

CORPORATE GOVERNANCE AND FINANCIAL INFORMATION

8.2.11. R&D TAX CREDITS INCENTIVES As a company that carries extensive research and development activities, the Company benefits from various grants and R&D incentives from certain governmental agencies. These grants and R&D incentives generally aim to partly reimburse approved expenditures incurred in research and development efforts of the Company and are credited to the income statement, in minus of the related R&D expenses, when the relevant expenditure has been incurred and there is reasonable assurance that the grants or R&D incentives are receivable. Research and development incentives receivables Non-current research and development incentives receivables are discounted over the period until maturity date according to the appropriate discount rates.

8.2.12. TRADE RECEIVABLES Trade receivables are initially recognised at fair value and subsequently measured at amortised cost using the effective interest method, less provision for impairment. A provision for impairment of trade receivables is established when there is objective evidence that the Company will not be able to collect all amounts due according to the original terms of the receivables.

8.2.13. OTHER SHORT-TERM INVESTMENTS Term deposits with an initial term of more than three months are held to maturity and measured at amortised cost.

8.2.14. CASH AND CASH EQUIVALENTS The cash and cash equivalents heading consists of cash, deposits held at call with banks and short-term deposits with an initial term not exceeding three months.

8.2.15. EQUITY INSTRUMENTS Equity instruments issued by the Company are recorded at the proceeds received, net of direct issuance costs.

ANNUAL REPORT 2015 / ABLYNX

131.

CORPORATE GOVERNANCE AND FINANCIAL INFORMATION

8.2.16. TRADE PAYABLES Payables after and within one year are measured at amortised cost, i.e. at the net present value of the payable amount. Unless the impact of discounting is material, the nominal value is taken.

8.2.17. CONVERTIBLE BONDS The convertible bond is considered as a financial liability with an embedded derivative liability consistent with IAS 32 based on the net share settlement, accounted for as follows: • Debt component recognised at amortised cost; • Embedded derivative accounted for at fair value.

The fair value of the conversion feature needs to be determined at each reporting date and the fair value changes are recognised in profit or loss.

As the fair value of the convertible bond as a whole can reliably be estimated, as well as the fair value of the host debt, the fair value of the embedded derivative is calculated as the difference between these two elements.

The fair value of the convertible bond is obtained from public sources (e.g. Bloomberg) which are deemed sufficiently representative of prices for actual market transactions.

The fair value of the host debt is determined by discounting the contractual cash flows using a market benchmark rate plus a market credit spread for a corresponding plain vanilla bond issued by Ablynx with same cash flows and same remaining term to maturity.

8.2.17.1. FAIR VALUE MEASUREMENT IFRS 7 requires disclosure of fair value measurements by level of the following hierarchy: • Level 1: Quoted (unadjusted) prices in active markets for identical assets or liabilities; • Level 2: Other techniques for which all inputs which have a significant effect on the recorded fair value are observable, either directly or indirectly; • Level 3: Techniques which use inputs which have a significant effect on the recorded fair value that are not based on observable market data.

ANNUAL REPORT 2015 / ABLYNX

132.

CORPORATE GOVERNANCE AND FINANCIAL INFORMATION

The characteristics of the convertible bond issued in May 2015 are such that, in accordance with “IAS 39, Financial Instruments: Recognition and Measurement”, it is broken down into two components in the balance sheet: (1) the host contract or plain vanilla debt (i.e. without the conversion option), which is measured at amortised cost and (2) the embedded derivative, i.e. the conversion option, which is measured at fair value through profit or loss. The fair value of the host contract is determined by discounting the contractual cash flows with the reference swap rate plus the appropriate credit spread and the transaction costs allocated to the host debt component. This fair value at inception is also the initial amortised cost of the plain vanilla debt. The fair value of the embedded derivative (i.e. the conversion option) is determined as the difference between the fair value of the total convertible debt and the fair value of the plain vanilla debt.

8.2.17.2. ADDITIONAL INFORMATION WITH REGARD TO FAIR VALUE OF THE FINANCIAL INSTRUMENTS The table below lists the different classes of financial assets and liabilities with their carrying amounts in the balance sheet and their respective fair value and analysed by their measurement category in accordance with “IAS 39, Financial Instruments”.

Cash and cash equivalents, short-term deposits, trade and other receivables, loans and receivables primarily have short terms to maturity; hence, their carrying amounts at the reporting date approximate the fair values. Trade and other payables also generally have short times to maturity and, hence, their carrying amounts also approximate their fair values.

8.2.17.3. OVERVIEW MUTATIONS OF LEVEL 3 FINANCIAL INSTRUMENTS MEASURED AT FAIR VALUE IN THE BALANCE SHEET At the balance sheet date, the quotation of the convertible bond on Bloomberg was deemed reliable as a fair value measurement. The loss in fair value of the embedded derivative amounted to €34.6 million.

8.2.18. INCOME TAXES Income taxes are accrued for in the same period as the related revenues and expenses. The taxable result can differ from the net profit or loss, because of revenues and expenses which are taxable in another fiscal year or that will never be taxable or deductible.

Deferred income tax is provided in full, using the liability method, on temporary differences arising between the tax bases of assets and liabilities and their carrying amounts in the financial statements. However, the deferred income tax is not accounted for if it 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 nor loss. Deferred income tax is determined using tax rates (and laws) that have been enacted or substantially enacted by the balance sheet date and are expected to apply when the related deferred income tax asset is realised or the deferred income tax liability is settled.

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

As such, a deferred tax asset for the carry forward of unused tax losses will be recognised to the extent that it is probable that future taxable profit will be available.

CORPORATE GOVERNANCE AND FINANCIAL INFORMATION

8.2.19. EMPLOYEE BENEFITS The Company offers several post-employment, death, disability and healthcare benefit schemes. All employees have access to these schemes. The death, disability and healthcare benefits granted to employees of the Company are covered by external insurance companies, where premiums are paid annually and charged to the income statement as they were incurred.

The post-employment pension plans granted to employees of the Company are based on defined contributions for which the insurance company guarantees a defined interest until retirement (type 'branche 21/tak21').

As a consequence of the law of 18 December 2015, minimum returns are guaranteed by the employer as follows: • for the contributions paid as from 1 January 2016, a new variable minimum return based on OLO rates, with a minimum of 1.75% and a maximum of 3.75%. In view of the low rates of the OLO in the last years, the return has been initially set to 1.75; • for the contributions paid until end December 2015, the previously applicable legal returns (3.25% and 3.75% respectively on the employer and employee contributions) continue to apply until retirement date of the participants.

In view of the minimum returns guarantees, those plans qualify as Defined Benefit plans.

In 2014, under the previous legal framework, the application of the PUC method was considered problematic, and there was uncertainty with respect to the future evolution of the minimum guaranteed rates of return. As a consequence, the Group adopted a retrospective approach whereby the net liability recognised in the statement of financial position was based on the sum of the positive differences, determined by individual plan participant, between the minimum guaranteed reserves and the accumulated contributions based on the actual rates of return at the closing date.

Based on the limited difference of €2,944, the Company has concluded that the application of the PUC method would have an immaterial impact.

In 2015, the sum of the positive differences per plan participant between the minimum guaranteed reserves (€6,256,832.58) and the accumulated reserves (€6,243,661.6) as of 31 December 2015 is €13,170.98.

As a consequence, in view of the immaterial difference between the accumulated reserves and the minimum reserves as of 31 December 2015, no provision has been recognised.

ANNUAL REPORT 2015 / ABLYNX

136.

CORPORATE GOVERNANCE AND FINANCIAL INFORMATION

8.2.20. PROVISIONS A provision is recognised only when: the Company has a present obligation to transfer economic benefits as a result of past events; it is probable (more likely than not) that such a transfer will be required to settle the obligation; and a reliable estimate of the amount of the obligation can be made.

When the impact is likely to be material (for long-term provisions), the amount recognised as a provision is estimated on a net present value basis (discount factor). The increase in provision due to the passage of time is recognised as an interest expense.

A present obligation arises from an obligating event and may take the form of either a legal obligation or a constructive obligation (a constructive obligation exists when the Company has an established pattern of past practice that indicates to other parties that it will accept certain responsibilities and as a result has created a valid expectation on the part of those other parties that it will discharge those responsibilities). An obligating event leaves the Company no realistic alternative to settling the obligation, independently of its future actions.

Provisions for decommissioning costs and restoring sites are recorded as appropriate in application of the above.

Provisions for future operating losses are strictly prohibited.

If the Company has onerous contracts (the unavoidable costs of meeting the obligations under the contract exceed the economic benefits expected to be received under it), the present obligations under the contract are recognised as a provision.

A provision for restructuring is only recorded if the Company demonstrates a constructive obligation to restructure at the balance sheet date. The constructive obligation should be demonstrated by: (a) a detailed formal plan identifying the main features of the restructuring; and (b) raising a valid expectation to those affected that it will carry out the restructuring by starting to implement the plan or by announcing its main features to those affected.

8.2.21. LEASES A financial lease is a lease that substantially transfers all the risks and rewards incident to ownership of an asset.

The cost of assets acquired by way of a finance lease is measured at the lower of the fair value of the leased asset and the present value of the minimum lease payments,

ANNUAL REPORT 2015 / ABLYNX

137.

CORPORATE GOVERNANCE AND FINANCIAL INFORMATION

using the interest rate implicit in the lease as the discount rate, both determined at the inception of the lease. Initially incurred costs, directly attributable to the arrangement of the finance lease, are added to the amount recognised as an asset.

Assets acquired under financial leases are depreciated over the shorter of the lease term and their estimated useful life, if it is not reasonably certain that the entity will obtain ownership of the asset by the end of the lease term.

Payments made under operating leases are charged to the income statement on a straight-line basis over the period of the lease.

8.2.22. SHARE-BASED PAYMENT TRANSACTIONS The Company has offered equity-settled, share-based compensation plans to its employees, executive management and consultants. The cost with respect to the employee services received in compensation for the grant of these warrants is recognised as an expense.

The total amount of the expense is recognised over the vesting period and determined on the basis of the fair value of the warrants at grant date. The fair value of each warrant is estimated on the date of grant using the Black-Scholes model. The total cost is initially estimated on the basis of the number warrants that will become exercisable.

At each balance date, the Company revises its estimates of the number of warrants that will become exercisable. The impact of the revision is recognised in the income statement over the remaining vesting period with a corresponding adjustment to equity.

8.2.23. EARNINGS PER SHARE Basic net profit/(loss) per share is computed on the basis of the weighted average number of ordinary shares outstanding during the period, excluding treasury shares.

Diluted net profit/(loss) per share is computed based on the weighted-average number of ordinary shares outstanding including the dilutive effect of warrants and bonds. Warrants and bonds should be treated as dilutive, when and only when their conversion to ordinary shares would decrease the net profit per share from continuing operations.

CORPORATE GOVERNANCE AND FINANCIAL INFORMATION

8.3. FINANCIAL RISK MANAGEMENT 8.3.1. FINANCIAL RISK FACTORS Liquidity risk management The Company makes use of term accounts and treasury notes. The maturities of the term deposits are limited to a maximum of one year.

The Company has €1.6 million restricted cash related to a cash pledge.

On 27 May 2015, the company raised €100 million through a private placement of €100 million senior unsecured bonds due 27 May 2020. The bonds will mature on 27 May 2020 (5 years) and will pay a coupon of 3.25% semi-annually.

The convertible bonds are convertible in Ablynx ordinary shares at the option of the holder. In case of conversion: a cash alternative election (at the option of the issuer) is available including a number of restrictions. Because the issuer has the cash alternative election, it has a choice over how the share conversion option will be settled (i.e. net in cash or by exchanging shares for cash). Therefore the share conversion option is a derivative at Fair Value Through Profit and Loss (“FVTPL”) according to IAS 39, not an own equity instrument (cf. IAS 32.26).

Interest rate risk The Company has a significant interest-bearing liability related to the private placement of €100 million senior unsecured bonds with a 3.25% coupon rate and a conversion price of €12.93. However, operating cash flows are independent of changes in market interest rates.

Credit risk The credit risk arises from outstanding transactions with customers. It is the Company’s policy to deal with creditworthy partners to avoid significant risk exposure. The trade receivables relate to a limited number of high-ranked international customers for whom there is no recent history of default. The credit risk is highly concentrated around a limited number of customers.

Available liquidities are placed with several financial institutions.

The financial institutions have credit ratings varying from A+, over A to A-.

No cash credit lines were available.

The Company did not enter into any currency hedging arrangements in order to cover this risk.

As per 31 December 2015, if the EUR had weakened 10% against the GBP and strengthened 10% against the USD with all other variables held constant, the loss of the period would have been €196,385 (2014: €610,456) higher. Conversely, if the EUR had strengthened 10% against the GBP and weakened 10% against the USD with all other variables held constant, the loss of the period would have been €191,835 (2014: €662,848) lower.

8.3.2. CAPITAL RISK MANAGEMENT The Company manages its capital to ensure that it will be able to continue as a going concern. The capital structure of the Company consists of limited financial debt, cash and cash equivalents, restricted cash and short-term investments and equity attributed to the holders of equity instruments of the Company, such as capital, reserves and results carried forward as mentioned in the statements of changes in equity. The Company makes the necessary adjustments in the light of changes in the economic circumstances, risks associated to the different assets and the projected cash needs of the current and projected research activities. The current cash situation and the anticipated cash generation are the most important parameters in assessing the capital structure. The Company objective is to maintain the capital structure at a level to be able to finance its activities for at least twelve months. Cash income from existing and new partnerships is taken into account and, if needed and possible, the Company can issue new shares or enter into financing agreements.

8.4. CRITICAL ACCOUNTING ESTIMATES AND JUDGEMENTS At each reporting date, the Company makes assumptions and estimates with respect to the impact of past events on the future resulting in a number of accounting estimates, which at present have a limited impact.

8.4.1. CONVERTIBLE BOND On 27 May 2015 Ablynx issued Senior Unsecured Convertible Bonds due May 2020 for an amount of €100.000.000 at an issue price of 100%. The convertible bonds are convertible in Ablynx ordinary shares at the option of the holder.

In case of conversion, a cash alternative election is available at the option of the issuer including a number of restrictions. Because the issuer has the cash alternative election,

ANNUAL REPORT 2015 / ABLYNX

141.

CORPORATE GOVERNANCE AND FINANCIAL INFORMATION

it has a choice over how the share conversion option will be settled (i.e. net in cash or by exchanging shares for cash). Therefore the share conversion option is a derivative at Fair Value Through Profit and Loss (“FVTPL”) according to IAS 39 and not an own equity instrument (cf. IAS 32.26).

An estimate of the value for the convertible bond is available on Bloomberg, the embedded derivative has been valued as the difference between the value of the convertible bond and the value of the bond floor.

The fair value is based on indicative (i.e. non-executable) quotes provided by 9 market participants resulting in indicative prices. The number of participants (and thus the Bloomberg reliability score) may still fluctuate overtime and impact the level of subjectivity of this method.

As long as no observable data (and grades) are available, a credit spread provided by Ablynx’ bank (i.e. JP Morgan –“JPM”) is being applied. This spread is to be updated for every valuation date.

As of the issue date, JPM uses a spread of 700bp for Ablynx. JPM bases the spread of 700bp on observations of debt issued by a number of comparable companies but considerable judgement remains.

8.4.2. TAX CREDIT The Company has accounted for a total tax receivable of €15.7 million following an R&D incentive scheme in Belgium under which the tax can be refunded after five years if not offset against taxable basis over that period. The R&D incentives are recorded net against the relating R&D expenses in the statement of comprehensive income. We expect to receive this amount progressively over 5 years, starting as from accounting year 2016 onwards. Beginning of 2016 €1.2 million has been refunded. The remaining amount of €14.5 million is expected in the following years. (€’000) Fiscal year

CORPORATE GOVERNANCE AND FINANCIAL INFORMATION

The collection of the outstanding non-current R&D tax credit receivable remains dependent upon the completeness of the necessary formalities and the quality of the documentation available to support tax credit claimed.

8.4.3. DEFERRED TAXES The total temporary differences amount to â&#x201A;Ź337.0 million which may result in a potential deferred tax asset of â&#x201A;Ź115.0 million.

Based upon the tax planning this deferred tax asset was not recognised as the midterm planning demonstrated significant uncertainty to realise taxable profits in the foreseeable future.

8.4.4. SHARE-BASED COMPENSATION The Company used the Black & Scholes model for share-based payment calculation purposes and based the volatility parameter on the volatility of the Ablynx share.

Rotation of employees as a parameter for share-based payment calculations is considered to be limited.

8.4.5. GOING CONCERN For the further successful expansion of the research and development activities, Ablynx is, among others, dependent on sufficient financial funding, the results obtained from research and Ablynx capacity to obtain and maintain adequate protection of its intellectual property. In addition, further progress of the clinical tests is planned in the next years, which will increase the operational costs.

On the other hand, commercial deals were closed which have already generated and which will generate important revenues as milestones are earned.

Going concern is assured as no liquidity problems are expected because the convertible bonds are convertible in Ablynx ordinary shares at the option of the issuer.

In case of conversion, a cash alternative election is available at the option of the issuer, including a number of restrictions. Because the issuer has the cash alternative election, it has a choice over how the share conversion option will be settled (i.e. net in cash or by exchanging shares for cash).

The Company has not identified at reporting date any sources of estimation uncertainty, which involve a significant risk of material adjustment to the financial statements in the following year.

ANNUAL REPORT 2015 / ABLYNX

143.

CORPORATE GOVERNANCE AND FINANCIAL INFORMATION

The current cash position of â&#x201A;Ź236.2 million including cash, other investments, restricted cash and deposits will allow the Company to keep up with the financial obligations for at least the following 12 months.

Consequently, the annual accounts have been prepared on the assumption that the Company is a going concern.

8.5. SEGMENT INFORMATION The Company does not distinguish different operating segments.

The income stems from nine pharmaceutical partners, namely Boehringer Ingelheim, Merck KGaA, Merck & Co., Inc., Novartis, AbbVie, Eddingpharm, Genzyme, Taisho Pharmaceuticals and Novo Nordisk. Moreover, in 2015, more than 90% of the income originated from 3 parties, one party was responsible for more than 50% of the income, two other parties represented between 15% and 25% each.

In 2014, 1 party represented more than 40% of the revenues, two other parties represented between 20% and 25% each.

CORPORATE GOVERNANCE AND FINANCIAL INFORMATION

On 27 May 2015, the Company raised €100 million through a private placement of €100 million senior unsecured bonds due 27 May 2020. The bonds were placed through an accelerated book building placement with qualified investors outside the United States, in accordance with Regulation S under the Securities Act. The bonds will mature on 27 May 2020 (5 years), are in dematerialised form in the denomination of €100,000 each, are issued at par and will be redeemed at par at maturity. The bonds will pay a coupon of 3.25% per annum, payable semi-annually in arrears on 27 November and 27 May of each year, beginning on 27 November 2015. The initial price for the conversion of the bonds into ordinary shares of the issuer is €12.93, representing approximately a 26.5% premium above the reference price of €10.2219, being the VWAP of the ordinary shares on Euronext Brussels on 20 May 2015. At the initial conversion price, the convertible bonds will be convertible into 7,733,952 fully paid-up ordinary shares of the issuer.

Conversion of the convertible bonds in Ablynx ordinary shares is at the option of the holder.

As the issuer has the cash alternative election, it has a choice over how the share conversion option will be settled (i.e. net in cash or by exchanging shares for cash). Therefore the share conversion option is a derivative at Fair Value Through Profit and Loss (“FVTPL”) according to IAS 39 and not an own equity instrument (cf. IAS 32.26).

8.15.4. EXTENSION OF CERTAIN WARRANT PLANS The General Shareholders Meeting of 30 April 2009 and the Board of Directors meeting of 22 June 2009 approved the five-year extension of certain warrant plans in accordance with Art. 583 of the Belgian Company Code and in accordance with Art. 21 of the “Economische Herstelwet”.

Because of this extension, the fair value of the warrants has changed. The incremental fair value was calculated as the difference between the fair value with and without extension at the date of extension.

CORPORATE GOVERNANCE AND FINANCIAL INFORMATION

The convertible bonds are convertible in Ablynx ordinary shares at the option of the holder. In case of conversion: a cash alternative election (at the option of the issuer) is available including a number of restrictions. Because the issuer has the cash alternative election, it has a choice over how the share conversion option will be settled (i.e. net in cash or by exchanging shares for cash). Therefore the share conversion option is a derivative at Fair Value Through Profit and Loss (“FVTPL”) according to IAS 39 and not an own equity instrument (cf. IAS 32.26).

Unrecognised deferred tax asset (33,99%) (1) The application of Notional Interest Deduction is restricted as it has an expiry term of 7 years

The Company has unused tax losses carry forward, without expiry date. This, combined with the other temporary differences, results in a net deferred tax asset position.

The Company has accounted for a total R&D tax credit receivable of €15.7 million following an R&D incentive scheme in Belgium under which the tax incentive can be refunded after five years if not offset against taxable basis over that period. The R&D incentives are recorded net against the relating R&D expenses in the statement of comprehensive income. We expect to receive this amount progressively over 5 years, starting as from accounting year 2016 onwards.

Due to the uncertainty surrounding the Company’s ability to realise taxable profits in the near future, the Company did not recognise any deferred tax assets.

8.19. RETIREMENT BENEFIT OBLIGATIONS The Company offers several post-employment, death, disability and healthcare benefit schemes. All employees have access to these schemes. The death, disability and healthcare benefits granted to employees of the Company are covered by external insurance companies, where premiums are paid annually and charged to the income statement as they were incurred.

ANNUAL REPORT 2015 / ABLYNX

167.

CORPORATE GOVERNANCE AND FINANCIAL INFORMATION

The post-employment pension plans granted to employees of the Company are based on defined contributions for which the insurance company guarantees a defined interest until retirement (type 'branche 21/tak21').

As a consequence of the law of 18 December 2015, minimum returns are guaranteed by the employer as follows: • for the contributions paid as from 1 January 2016, a new variable minimum return based on OLO rates, with a minimum of 1.75% and a maximum of 3.75%. In view of the low rates of the OLO in the last years, the return has been initially set to 1.75; • for the contributions paid until end December 2015, the previously applicable legal returns (3.25% and 3.75% respectively on the employer and employee contributions) continue to apply until retirement date of the participants.

In view of the minimum returns guarantees, those plans qualify as Defined Benefit plans.

In 2014, under the previous legal framework, the application of the PUC method was considered problematic, and there was uncertainty with respect to the future evolution of the minimum guaranteed rates of return. As a consequence, the Group adopted a retrospective approach whereby the net liability recognized in the statement of financial position was based on the sum of the positive differences, determined by individual plan participant, between the minimum guaranteed reserves and the accumulated contributions based on the actual rates of return at the closing date.

Based on the limited difference of €2,944, the Company has concluded that the application of the PUC method would have an immaterial impact.

In 2015, the sum of the positive differences per plan participant between the minimum guaranteed reserves (€6,256,832.58) and the accumulated reserves (€6,243,661.6) as of 31 December 2015 is €13,170.98.

As a consequence, in view of the immaterial difference between the accumulated reserves and the minimum reserves as of 31 December 2015, no provision has been recognised.

11.2. SPECIFIC RULES Company Formation Expenses Formation expenses are charged directly to the profit and loss account.
