CEO STATEMENT

European approval for Kinpeygo^®

On May 19th, the European Medicines Agency (EMA) announced that it had adopted a positive opinion regarding the application for conditional approval of Kinpeygo^® for the treatment of IgA nephropathy, and on July 15th the European Commission issued the market authorization for Kinpeygo in Europe.

This is the first time that any drug has achieved approval for this rare disease in Europe and we are delighted that we can contribute a piece of the puzzle in the broader effort to improve care for patients with orphan diseases. We have now initiated the transfer of our market authorization to our partner, STADA, and look forward to seeing Kinpeygo being launched in Europe. Having now received approval in both the US and Europe we are looking forward to the regulatory process in China, where our partner, Everest Medicines, plans to file for approval with the NMPA in the second half of this year.

In the US we continue to have significant success in our early commercial efforts. Net revenues from TARPEYO^® grew by well over 250% when compared to Q1, resulting in net revenues of SEK 64 million ($6.6m) from TARPEYO for Q2. This reflects the continued strong interest from nephrologists, with unique prescribers growing from 111 in Q1 to 314 prescribers during Q2 with enrolments growing signifcantly from 134 in Q1 to 315 in Q2. This is a testament both to the unmet medical need perceived by nephrologists for this patient group as well as significant interest from prescribers generated due to the strong proteinuria and eGFR data associated with our product.

The US operation continues to grow as we add complementary resources in key areas. The multidisciplinary team continues to reach out to physicians across multiple channels in support of our commercial activities and positive momentum continues to build in the market. We believe the combination of the significant proteinuria reduction vs ACE / ARB therapy at 9 months (-31%) and the continued significant decline in proteinuria observed 3 months after withdrawal of the treatment (-52%) that we observed in the Phase 3 trial reflect the differentiated mechanism of action of TARPEYO. Its design, which specifically targets the origin of the disease, continues to drive strong interest from both patients and nephrologists, who seem especially impressed by the impact on eGFR during the 9 months of treatment. In order to fully support this growing interest, we decided post this period’s end to expand our US sales force to encompass a total of 60 sales executives expected, with recruitment of an additional 20 sales executives in Q3 and who will become fully operational in Q4. We are truly excited about this development which further builds on TARPEYO’s initial commercial success and our commitment to ensure that TARPEYO continues to be readily available for appropriate patients with IgA nephropathy.

The second quarter also saw the dosing of the first patient in our Phase 2 study in head and neck cancer, studying the efficacy and safety of the lead candidate from our proprietary NOX platform, setanaxib. There is significant interest in cancer associated fibroblasts (CAFs) from a variety of industry participants and we look forward to hopefully sharing biomarker data with you before the end of the year.

Calliditas Therapeutics | Interim Report Q2: January – June 2022 3

In Q2 we also revisited the existing credit line with Kreos regarding the final $25 million tranche under the $75 million non-dilutive loan facility we put in place mid 2021. As a result, we do not have any specific operational requirements and are thus able to draw down the last tranche at any time before the end of December, 2022. In addition, we expect to receive €12.5m (approximately SEK 130 million) in milestone payments related to the approval and commercial launch of Kinpeygo in Europe from STADA during the second half of 2022.

We are thrilled to be another step closer to bringing the first approved medication in IgAN to patients around the world and look forward to continuing to expand access for patients with an unmet medical need for the rest of the year and beyond.

BUSINESS OVERVIEW

Our Commercial Product

Calliditas’ lead product, which was granted accelerated approval by the US Food and Drug Administration (FDA) in December 2021 and conditional marketing authorization by the European Commission in July 2022, is the first treatment specifically designed to target the origin of the autoimmune kidney disease IgA Nephropathy (IgAN).

IgAN is a serious progressive disease, in which up to 50% of patients end up at risk of developing end-stage renal disease (ESRD) within ten to twenty years. This product, which was developed under the name NEFECON, is approved under the brand name TARPEYO^® in the United States and under the brand name Kinpeygo^® in Europe.

Disease Background

Although IgAN manifests in the kidney, the evidence indicates that it is a disease that starts in the distal part of the intestine, specifically in the ileum. Peyer’s patches, which are concentrated within the gut-associated lymphoid tissue in the ileum, have been identified as a major source of mucosal-type IgA antibodies. Patients with IgA nephropathy have elevated levels of mucosal-type IgA, which – in contrast to the majority of the IgA in the blood - are predominately dimeric or polymeric and are galactose deficient. In IgAN patients, a combination of a genetic predisposition and of environmental, bacterial and dietary factors is presumed to lead to an increased production of these galactose-deficient IgA antibodies. This increased production, potentially in conjunction with increased intestinal permeability, leads to these secretory antibodies appearing in the blood.

The galactose-deficient spot at the hinge region of the IgA antibodies is immunogenic when found in the circulation. It therefore generates an autoimmune response, attracting autoantibodies in the form of IgG or IgA and form pathogenic immune complexes that deposit in the glomeruli, the kidney’s filtration apparatus. The trapped immune complexes initiate an inflammatory cascade which damages the kidney and ultimately destroys its filtration mechanism. This leads to slow, progressive deterioration of renal function, which in many patients ultimately results in the need for dialysis or kidney transplant.

Calliditas’ lead product is an oral, delayed release formulation of budesonide, a corticosteroid with potent glucocorticoid activity and weak mineralocorticoid activity that undergoes substantial first pass metabolism. It was designed as a 4 mg delayed release capsule with an enteric coating so that it remains intact until it reaches the ileum. Each capsule contains beads coated with various polymers and budesonide designed to target the area with the highest concentration of Peyer’s patches, with the intention of having a disease-modifying effect.

Data

Calliditas’ regulatory filings with the FDA and European Medicines Agency (EMA) were based on positive data from Part A of the NefIgArd pivotal Phase 3 study, which read out topline data in November 2020. Patients taking NEFECON showed a statistically significant 31% reduction in proteinuria from baseline vs 5% in the placebo cohort at 9 months; in the intention to treat (ITT) population, the reduction at 9 months of treated patients was 34%. Furthermore, for patients who had reached 12 months at the time of the data cut-off, the proteinuria reduction was 52%. The key secondary endpoint, eGFR, showed a treatment benefit of 7% versus placebo at 9 months, reflecting stabilization in the treatment arm and a 7% decline of eGFR in the placebo arm (p=0.0029). This reflected an absolute decline of 4.04 ml/min/1.73m² in the placebo group over 9 months compared to a 0.17 ml/min/1.73m² decline in the treatment arm. The trial also demonstrated that NEFECON was well-tolerated.

Our Commercial Product (cont.)

Approval in the US

The product is approved under the accelerated approval pathway under the brand name TARPEYO^® in the United States. TARPEYO is indicated to reduce proteinuria in adults with primary immunoglobulin A nephropathy (IgAN) at risk of rapid disease progression, generally defined as a urine protein-to-creatinine ratio (UPCR) ≥1.5g/g. Itis the first and only FDA-approved treatment for IgA nephropathy.

Calliditas has been granted orphan drug designation for the treatment of IgAN in the United States and is commercializing TARPEYO in the United States on its own.

Approval in Europe

In July 2022, the product was granted conditional marketing authorization by the European Commission under the brand name Kinpeygo^® for the treatment of IgA nephropathy (IgAN) in adults at risk of rapid disease progression with a urine protein-to-creatinine ratio (UPCR) ≥1.5 g/ gram. Kinpeygo is an orphan medicinal product and became the first and only approved treatment for IgAN in the European Economic Area (EEA).

Kinpeygo will be marketed in the EEA exclusively by STADA Arzneimittel AG with whom Calliditas entered into a license agreement in July 2021. The deal with STADA to register and commercialize Kinpeygo in the European Economic Area (EEA) member states, Switzerland and the UK was valued at a total of EUR 97.5 million, plus royalties. Under the terms of the agreement, Calliditas received an initial upfront payment of EUR 20 million upon signing and is entitled to up to an additional EUR 77.5 million in future payments linked to pre-defined regulatory and commercialization milestones. STADA is also due to pay tiered royalties on net sales expressed as a percentage between the low twenties and the low thirties.

Greater China, Singapore and South Korea

Calliditas also has a commercial partner in China and Singapore, having entered into a license agreement to develop and commercialize NEFECON for IgAN in those markets with Everest Medicines in 2019. Calliditas received an initial upfront payment of USD 15 million upon signing, as well as future payments linked to development, regulatory and commercialization milestones up to an additional USD 106 million, plus royalties. In March 2022, this agreement was expanded to include South Korea. Everest Medicines will look to file with regulators in China in 2H 2022, with a view to target potential approval in 2023.

Building on a Successful Commercial Launch

In our second and first full quarter of sales of TARPEYO^®, the commercial team has continued to build on the foundation established in Q1 subsequent to TARPEYO’s approval. The enthusiasm for TARPEYO from physicians and patients has been encouraging, we are pleased with the progress that has been made to date, and we remain confident in our ability to continue our growth, this year and beyond.

Since TARPEYO’s launch in late January, there have been a total of 450 patient enrollments, with 235% more enrollments in Q2 compared to Q1. All patients are guided through the enrollment and procurement process with the support of our patient services program, TARPEYO Touchpoints™, which has been assisting physicians and patients via a designated Rare Pod Team – including nurses, pharmacists, and a fulfilment and distribution team.

The Calliditas market access team continues to engage with payers and focus on the key targeted payers that cover most American lives. While the review process for coverage and formulary placement is on-going it typically takes six to nine months. When we look at coverage, as reported by Breakaway Partners, a Komodo Health Company, well over 80% of US lives are covered for TARPEYO.

Following the required FDA review related to accelerated approved medications, we launched our branded campaign during Q2. The multimedia campaign focuses on the unique mechanism of action of TARPEYO and the efficacy and safety results achieved in the clinic. Supported by our medical affairs education and marketing campaign, the adoption of TARPEYO by physicians has been quick and after only 5 months of promotion awareness of our drug is high, with unaided awareness at 70% and aided awareness at 80%. A total of 314 prescribers to date have prescribed TARPEYO for their patients, reflecting a broad interest in the drug.

Calliditas Therapeutics | Interim Report Q2: January – June 2022 7

Our medical affairs team has been active at the big symposia and congresses, such as the National Kidney Foundation’s yearly Spring Clinical Meetings educational event. We also continue to work with patient advocacy groups and were thrilled to continue to lend our support to the IgA Nephropathy Foundation as it worked towards hosting its yearly symposium, SPARK 2022, in July.

Our specialty sales team has continued to build on the strong results in Q1, recording net sales for the second quarter of $6.6M (SEK 64 million), more than tripling net sales compared to Q1. We are now, in light of the broad and strong demand, planning to expand our sales force with the aim of further bolstering our reach and frequency of contact, empowering our sales team to support the demand from the physician audience and increase the individual frequency of meetings and of face-to-face interactions.

Pipeline: NOX Inhibitor Platform

Calliditas’ pipeline contains development programs based on a first in class, novel NOX inhibitor platform. The lead compound, setanaxib, is the first NOX inhibitor to reach the clinical trial stage and is a selective NOX 1 and NOX 4 inhibitor. Calliditas is presently running trials with setanaxib in Primary Biliary Cholangitis (PBC) and in Squamous Cell Carcinoma of the Head & Neck (SCCHN).

NOX Enzymes

NOX enzyme inhibitors are a set of promising novel experimental drugs in a new therapeutic class, recognised by the WHO since 2019 when it approved “naxib” as a new stem. Nicotinamide adenine dinucleotide phosphate (NADPH) oxidases, otherwise known as NOX enzymes, are the only known enzymes that are solely dedicated to producing reactive oxygen species (ROS) as their primary and sole function. They are transmembrane enzymes that transfer electrons from NADPH in the cytoplasm across the cell membrane, which results in the formation of ROS.

At appropriate concentrations, ROS have essential functions in cellular signaling processes, but disruption of the redox homeostasis has been implicated in multiple disease pathways. Setanaxib inhibits NOX1 and NOX4, enzymes which are implicated in inflammation and fibrosis pathways.

Setanaxib in Primary Biliary Cholangitis

PBC is a progressive and chronic autoimmune disease of the liver that causes a cycle of immune injury to biliary epithelial cells, resulting in cholestasis and fibrosis. It is an orphan disease and, based on its known prevalence rates, we estimate that there are approximately 140,000 patients in the US, where the annual incidence ranges from 0.3 to 5.8 cases per 100,000.

Ursodeoxycholic acid, a generic drug also known as ursodiol or UDCA, and obeticholic acid, known as Ocaliva, are the only FDA- and EMA-approved treatments for PBC. However, despite these treatment options, there is still an unmet medical need among PBC patients, in particular when it comes to important quality of life outcomes.

Calliditas has initiated a pivotal 52-week, randomized, placebo-controlled, double-blind, trial with an adaptive Phase 2b/3 design. Calliditas announced that the first patient was randomised in the TRANSFORM study on 15th February 2022.

Calliditas Therapeutics | Interim Report Q2: January – June 2022 9

Setanaxib will be administered to approximately 318 patients with PBC and elevated liver stiffness as well as intolerance or inadequate response to UDCA in a global trial conducted in up to 150 investigational centres. The primary endpoint is ALP reduction, with key secondary endpoints including change in liver stiffness and effect on fatigue and pruritus (itching). Following favorable safety data from a Phase 1 study, this trial will evaluate two dosing regimens of 1200mg/daily and 1600mg/daily. An interim analysis will be conducted once the 99th randomized patient has completed the Week 24 visit, which is expected in Q2 or Q3 2023, and will determine which dose of setanaxib will be used for the Phase 3 part of the study. The trial is expected to read out final data in late 2024 or early 2025. In August 2021, Calliditas received FDA Fast Track Designation for setanaxib in PBC.

ǂDose of 1600 mg daily administered as 800 mg AM and 800 mg PM

Pipeline: NOX Inhibitor Platform

Setanaxib in Squamous Cell Carcinoma of the Head & Neck

Calliditas also intends to evaluate setanaxib in head and neck cancer. The response to immuno-oncology therapies can be affected by the tumour microenvironment, in particular by the numbers of tumour-infiltrating lymphocytes (TILs) and cancer-associated fibroblasts (CAFs) in the tumour. A relationship between cancer associated fibroblasts (CAFs) and prognosis in Squamous Cell Carcinoma of the Head & Neck (SCCHN) has been established.

NOX4 is highly over-expressed in CAFs and drives myofibroblastic activation within tumours, shielding them from CD8+ TILs. Targeting CAFs with setanaxib could improve patients’ responses to immunotherapies, and function as an adjunct therapy. There is increasing use of pembrolizumab as 1st line monotherapy in patients with relapsed or metastatic SCCHN, although response rates are low (ORR approx. 20%).

Using a CAF-rich tumour model in mice, administration of setanaxib + pembrolizumab (versus either treatment alone) resulted in:

● Improved penetration of TILs into the centre of the tumour

● Slowing of tumour growth and improved survival

Calliditas Therapeutics | Interim Report Q2: January – June 2022 11

Proof-of-concept study in head and neck cancer

Calliditas is conducting a Phase 2 proof-of-concept study in patients with head and neck cancer, which will investigate administration of setanaxib in conjunction with immunotherapy targeting CAFs.

The study will likely involve approximately 50 patients. The first patient was randomised in Q2 2022, with an interim readout expected in late 2022 and final data read out expected in H2 2023.

Significant Events

Significant Events During the Period January 1 – June 30, 2022

· In January 2022, Calliditas announced the commercial availability and initial sales of TARPEYO (budesonide), the first and only FDA approved treatment for IgA nephropathy, indicated for reduction of proteinuria in adults with primary IgA nephropathy (IgAN) at risk of rapid disease progression, generally considered a urine protein-to-creatinine ratio (UPCR) ≥1.5g/g. Calliditas is committed to working with payers and healthcare providers across the United States to help ensure that all patients prescribed TARPEYO have access to it. To assist patients and their healthcare providers who would prescribe TARPEYO, Calliditas has launched a comprehensive patient support program, TARPEYO Touchpoints™. This program offers services, assistance, and resources designed to help patients access treatment as easily as possible.

· In February 2022, Calliditas announced that the first patient had been randomized in the company’s pivotal phase 2b/3 TRANSFORM study in patients with primary biliary cholangitis (PBC). The TRANSFORM trial is a 52-week, randomized, placebo-controlled, double-blind, adaptive Phase 2b/3 trial. It will initially investigate the effect of setanaxib 1200 mg/day and 1600 mg/day versus placebo on alkaline phosphatase (ALP) reduction in patients with PBC and with elevated liver stiffness and intolerance or inadequate response to ursodeoxycholic acid (UDCA). Key secondary endpoints include change from baseline in liver stiffness, assessed by transient elastography (FibroScan^®), and change from baseline in fatigue. An interim analysis will be conducted once the 99th randomized patient has completed the Week 24 visit, which is expected Q2 or Q3 2023. The interim analysis outcome will determine which of the two doses will be selected for the Phase 3 portion of the trial.

· In March 2022, Calliditas announced that the company had expanded its licensing agreement with Everest Medicines to extend the territory covered to include South Korea. The extension results in an upfront payment of USD 3 million to Calliditas as well as additional payments and royalties related to future potential approvals and commercialization of Nefecon in South Korea. Calliditas and Everest Medicines entered into a license agreement in 2019 to develop and commercialize Nefecon in Greater China and Singapore for the chronic autoimmune kidney disease IgA Nephropathy (IgAN).

· In May 2022, Calliditas announced that the first patient has been randomized in the Group’s proof-of-concept Phase 2 study in patients with squamous cell carcinoma of the head and neck (SCCHN) with the NOX 1 and 4 inhibitor, setanaxib.

· In May 2022, Calliditas announced that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) adopted a positive opinion recommending the granting of a conditional marketing authorisation for Kinpeygo for the treatment of primary immunoglobulin A (IgA) nephropathy (IgAN) in adults at risk of rapid disease progression with a urine protein-to-creatinine ratio (UPCR) ≥1.5 g/gram.

· In May 2022, the Annual General Meeting (AGM) of Calliditas was held and, among other things, the AGM resolved on the election of Henrik Stenqvist and Elisabeth Björk to the Board of Directors and the establishment of a U.S. At-the-Market framework of up to a maximum of 5,908,019 shares, pursuant to which Calliditas may, at its option, sell American Depositary Shares (“ADSs”) in the United States at market price, from time to time, in “at the market” transactions on The Nasdaq Global Select Market.

Revenue

Net sales amounted to SEK 64.0 million for the three months ended June 30, 2022 and for the six months ended June 30, 2022 net sales amounted to SEK 113.8 million. No net sales were recognized during the three and six months ended June 30, 2021, respectively. Net sales for the three and six months ended June 30, 2022 primarily originates from net sales of TARPEYO in the U.S., which amounted to SEK 63.6 million for the three months ended June 30, 2022 and SEK 81.6 million for the six months ended June 30, 2022. Further, for the six months ended June 30, 2022, net sales also consisted of the milestone fee from Everest Medicines for the extension of the license agreement for South Korea which amounted to SEK 28.8 million. For additional information see Note 4.

Total Operating Expenses

Total operating expenses amounted to SEK 271.5 million and SEK 159.4 million for the three months ended June 30, 2022 and 2021, respectively. For the six months ended June 30, 2022 and 2021, total operating expenses amounted to SEK 529.0 million and SEK 310.2 million, respectively.

For the six months ended June 30, 2022 and 2021, administrative expenses amounted to SEK 107.4 million and SEK 65.4 million, respectively. The increase of SEK 32.9 million for the three months ended June 30, 2022 and SEK 42.0 million for the six months ended June 30, 2022 was primarily related to general cost increases due to a larger organization and increased regulatory requirements compared to the corresponding periods in the prior year.

Other Operating Incomes/Expenses

Other operating income amounted to SEK 0.3 million and SEK 0.4 million for the three months ended June 30, 2022 and 2021, respectively. For the six months ended June 30, 2022 and 2021, other operating income amounted to SEK 1.1 million and SEK 0.4 million, respectively. Other operating expenses amounted to SEK 3.4 million and SEK 0.4 million for the three months ended June 30, 2022 and 2021, respectively. For the six months ended June 30, 2022 and 2021, other operating expenses amounted to SEK 5.9 million and SEK 2.3 million, respectively. The increase in other operating expenses for the three and six months ended June 30, 2022, was primarily related to a more disadvantageous exchange rate development on operating liabilities compared to the corresponding periods of the prior year.

Net Financial Income and Expenses

Net financial income/(expenses) amounted to SEK 17.8 million and (SEK 5.8 million) for the three months ended June 30, 2022 and 2021, respectively. For the six months ended June 30, 2022 and 2021, net financial income amounted to SEK 14.7 million and SEK 8.8 million, respectively. The increase of SEK 23.6 million for the three months ended June 30, 2022 and SEK 5.9 million for the six months ended June 30, 2022 was primarily derived by currency effect related to intercompany loan and unrealized foreign currency transaction gains on cash accounts.

Tax

Income tax expenses, in all material respects, primarily relates to the U.S. subsidiaries of Calliditas Therapeutics. Deferred tax assets of SEK 5.3 million related to Calliditas Therapeutics Suisse have been recognized in the six months ended June 30, 2022, due to future temporary differences that such losses can be used to offset. The Group’s tax losses carried forward have not otherwise been valued and not recognized as deferred tax assets. Deferred tax assets will be recognized for unused tax losses to the extent that it is probable that taxable profit will be available against which the losses can be utilized.

For the three months ended June 30, 2022 and 2021, loss for the period amounted to SEK 192.4 million and SEK 164.2 million, and the corresponding loss per share before and after dilution amounted to SEK 3.62 and SEK 3.22, respectively. For the six months ended June 30, 2022 and 2021, loss for the period amounted to SEK 399.5 million and SEK 297.0 million, and the corresponding loss per share before and after dilution amounted to SEK 7.57 and SEK 5.84, respectively.

For the six months ended June 30, 2022 and 2021, cash flow used in operating activities amounted to SEK 416.7 million and SEK 267.1 million, respectively. The increase in cash flow used in operating activities for the three and six months ended June 30, 2022, were primarily explained by the increase in sales and marketing expenses for the TARPEYO sales in the U.S. and the Group’s increased clinical activities for setanaxib compared to the corresponding periods of the prior year.

Cash flow used in investing activities amounted to SEK 0.1 million and SEK 18.6 million for the three months ended June 30, 2022 and 2021, respectively. For the six months ended June 30, 2022 and 2021, cash flow used in investing activities amounted to SEK 2.8 million and SEK 18.8 million, respectively. The decrease in cash flow used in investing activities for the three and six months ended June 30, 2022 were mainly derived from a EUR 1.5 million milestone payment for the Budenofalk license, which occurred the corresponding periods of the prior year.

Further for the six month period, the increase in cash flow from financing activities was also derived from the payments related to the exercise of warrant program 2018/2022.

Notes to Condensed Consolidated Financial Statements

Note 1 - Description of Business

Calliditas Therapeutics AB (publ) (“Calliditas” or the “Parent Company”), with corporate registration number 556659-9766, and its subsidiaries (collectively, the “Group”) conducts commercial and development activities in pharmaceuticals. These interim condensed consolidated financial statements encompass the Group, domiciled in Stockholm, Sweden, and its subsidiaries for the six months ended June 30, 2022 and 2021, respectively.

Calliditas is a Swedish public limited company registered in and with its registered office in Stockholm. The registered address of the corporate headquarters is Kungsbron 1, D5, Stockholm, Sweden. Calliditas is listed at Nasdaq Stockholm in the Mid Cap segment with ticker “CALTX” and, in the form of ADSs, on the Nasdaq Global Select Market in the United States with the ticker “CALT”.

These interim condensed consolidated financial statements were approved by the Board of Directors (the “Board”) for publication on August 18, 2022.

This report may include forward-looking statements. Actual outcomes may deviate from what has been stated. Internal factors such as successful management of research projects, and intellectual property rights may affect future results. There are also external conditions, (e.g. the economic climate, political changes, and competing research projects) that may affect the Group’s results.

Note 2 - Accounting Policies

These interim condensed consolidated financial statements have been prepared in accordance with International Accounting Standard No. 34 (IAS 34), “Interim Financial Reporting”. The Parent Company applies the Swedish Financial Reporting Board recommendation RFR2, Accounting for legal entities. None of the new or amended standards and interpretations that became effective January 1, 2022, have had a significant impact on the Group’s financial reporting. Significant accounting principles can be found on pages 41-46 of the Annual Report for 2021.

The ESMA (European Securities and Markets Authority) guidelines on alternative key performance ratios are applied, which means disclosure requirements regarding financial measures that are not defined in accordance with IFRS. For key ratios not defined by IFRS, see the Definitions and reconciliations of alternative performance measures on pages 33-34.

Note 3 - Risks and Uncertainties in the Group and the Parent Company

Operational Risks

Research and drug development up to approved registration is subject to considerable risk and is a capital-intensive process. The majority of all initiated projects will never reach market registration due to the technological risk such as the risk for insufficient efficacy, intolerable side effects or manufacturing problems. Competing pharmaceuticals can capture market share or reach the market faster, or if competing research projects achieve better product profiles, the future value of the product portfolio may be lower than expected. The operations may also be impacted negatively by regulatory decisions, such as lack of approvals and price changes.

Calliditas has a product in the commercial phase, which is marketed under the brand name TARPEYO, which has been approved for marketing in the U.S, and under the brand name Kinpeygo, which has been approved for marketing in EU. There is a risk that commercialization will not go according to plan or that the uptake of prescribing physicians will be worse than planned or that the drug will not have sufficient effect or show unwanted side effects, which may affect the sales negatively.

COVID-19

The COVID-19 virus has rapidly spread from an initial event and infections have been reported globally. Calliditas has clinical trial sites based in areas currently affected by this coronavirus. Calliditas has not yet experienced any major disturbances in the trials. The extent to which the coronavirus impacts the operations and the trials, or any planned trials for Nefecon or setanaxib, will depend on the type, degree and duration of the various restrictions put in place to contain the virus or treat those affected. This today varies in different geographies, and future developments cannot be predicted with reasonable assurance.

Calliditas Therapeutics | Interim Report Q2: January – June 2022 27

The pandemic may negatively impact our trial as a result of disruptions, such as travel bans, quarantines, and inability of patients to access the trial sites and provide samples as well as interruptions in the supply chain, which could result in delays and impact on the data integrity of the trial. The impact of the coronavirus outbreak for Calliditas have been limited so far, but the continued spread of the coronavirus globally, may negatively impact our operations, including our trials. It could also negatively affect the operations of key governmental agencies, such as the FDA and EMA, which may delay the development of our product candidates, or could result in the inability of our suppliers to deliver components or raw materials on a timely basis, each of which in turn could have a negative impact on our business and results of operations.

Financial Risks

Calliditas’ financial policy governing the management of financial risks has been designed by the Board of Directors and represents the framework of guidelines and rules in the form of risk mandated and limits for financial activities. The Group is primarily affected by foreign exchange risk, since the development costs for Nefecon and setanaxib are mainly paid in USD and EUR. Further, the Group maintains cash in USD and EUR to meet future expected costs in USD and EUR in connection with commercialization of TARPEYO in the United States and the clinical development programs. Regarding the Group and the Parent Company’s financial risk management, the risks are essentially unchanged compared with the description in the Annual Report for 2021.

For more information and full disclosure regarding the operational and financial risks, reference is made to the Annual Report for 2021 and the Annual Report on Form 20-F, filed with the SEC in April 2022.

The Group’s revenues for the three and six months ended June 30, 2022 primarily originates from net sales of TARPEYO in the U.S. Further for the six months ended June 30, 2022, net sales also consisted of the milestone fee from Everest Medicines for the extension of the license agreement for South Korea.

Revenue from product sales is recognized at the transaction price of goods sold excluding VAT, rebates and returns. At the time of delivery, when the control of the goods passes to the customer, the revenue is recognized in full, as this represents the single performance obligation in the transaction. The customer is defined as the specialty pharmaceutical who dispenses the good to the end user. As the final price is related to the rebate paid to the patients’ insurance company, the transaction price is not known upon delivery. This is accounted for by an accrued estimated rebate deduction in the Group based on calculation models considering statistical data, actual amounts incurred and/or historical trends. These liabilities for expected returns and rebates are based on estimates of the amounts earned or to be claimed on the related sales. Furthermore, the Group estimates the liability for expected returns of obsolete medicines that is recognized in the accounts. As of June 30, 2022 the total liability for expected returns and rebates amounts to SEK 6.9 million. In addition, there are no other performance obligations.

Calliditas Therapeutics | Interim Report Q2: January – June 2022 28

Revenue attributable to out-licensing Nefecon consisted of the agreement with STADA for Europe and the expansion of Everest Medicines to South Korea. Revenue for out-licensing is recognized at a point in time, which occurs when control over the intangible asset is transferred to the counterparty, which was at the time when the agreements with both parties was signed. Variable remuneration (for example, attributable to future regulatory milestones) is recognized when there is no longer any significant uncertainty as to whether these will occur. Compensation attributable to sales-based milestones or royalties are not recognized until the sale that results in the right to milestones or royalties arises.

Calliditas has identified three performance obligations under the agreement with STADA: 1) Out-licensing of the product candidate Nefecon as is at the time of signing, 2) Contractual obligation to perform the regulatory process with the EMA to obtain Conditional Regulatory Approval and 3) The obligation to supply Nefecon. The share of the transaction amount attributable to the EMA regulatory process has not been recognized as revenue and has been calculated based on the estimated cost to finish this process. The proportion attributable to out-licensing has been calculated as a residual of the remaining transaction price after deduction of other performance obligations, since the product candidate has not been approved for market by the regulatory authorities and no commercial pricing occur. Calliditas has completed all the performance obligations within the agreement with Everest Medicines.
