10. Borrowings

​

​

On December 10, 2018 ProQR was awarded an Innovation credit for the sepofarsen program. Amounts were drawn under this facility from 2018 through 2022. The credit of € 3,907,000 was used to conduct the Phase 2/3 clinical study and efforts to obtain regulatory and ethical market approval (New Drug Applications (“NDA”)/ Marketing Authorization Applications (“MAA”)) of sepofarsen for LCA10. In 2023, ProQR made a partial repayment of the principal, amounting to € 1,008,000. The remaining amount payable of € 2,899,000 and accrued interest is recognized under current borrowings at September 30, 2024 and non-current borrowings at December 31, 2023.

​

In December 2023, ProQR received a conditional waiver of the balance of the Innovation credit including accrued interest. Consequently, the repayment of the total loan of € 4,510,000, including interest, will be waived if conditions are met, which will be reviewed annually.

​

In September 2022, ProQR extinguished its debt with Pontifax and Kreos by repaying all outstanding principal amounts. Pontifax’ and Kreos’ warrants remain in place until their five-year economic life expires in 2025 and 2026. These warrants are accounted for as embedded derivatives and were recognized separately from the host contract as derivative financial liabilities at fair value through profit or loss.

Convertible loans

Convertible loans were issued to Amylon Therapeutics B.V. (“Amylon”), an 80% subsidiary of the Company, and were interest-bearing at an average rate of 8% per annum. They were convertible into a variable number of ordinary shares within 36 months at the option of the holder or the Company in case financing criteria were met. Any unconverted loans became payable on demand after 24 – 36 months in equal quarterly terms.

In 2023 and 2022, Amylon entered into waiver agreements with its lenders. Such lenders’ loan agreements with Amylon are severed and any claims to repayment of any outstanding debt and accumulated interest are renounced. The amount of convertible loans and accumulated interest that was waived under these agreements in the nine month period ended September 30, 2024 is € nil (nine month period ended September 30, 2023: € 1,866,000).

In the third quarter of 2023, Amylon was legally dissolved.

22. Events After Balance Sheet Date

On October 22, 2024, the Company consummated an underwritten public offering of 18,000,000 ordinary shares (the “Offering”) at a weighted average issue price of $3.50 per share. In addition, ProQR has granted the underwriters a 30-day option to purchase up to 2,700,000 additional ordinary shares at the public offering price, less underwriting discounts and commissions. The option was exercised on October 31, 2024, resulting in the issuance of 1,940,072 shares. The gross proceeds from the Offering and subsequent exercise of the underwriter’s option, amounted to $69.8 million (€64.6 million) while the transaction costs amounted to approximately €4.1 million, resulting in net proceeds of approximately €60.4 million which were received in October 2024.

Concurrently with the Offering, ProQR has entered into a share purchase agreement with Lilly pursuant to which ProQR agreed to offer and sell, and Lilly agreed to purchase, 3,523,538 ordinary shares at a price per share equal to the public offering price for total gross proceeds of approximately $12.3 million, subject to a purchase price cap of $15.0 million, the consummation of the Offering and the satisfaction of other customary closing conditions. The proceeds of $12.3 million (€11.4 million) from this concurrent private placement were received on October 25, 2024. The ordinary shares purchased in the concurrent private placement are not subject to any underwriting discounts or commissions.

4. Critical Accounting Estimates and Judgments

In the application of the Company’s accounting policies, management is required to make judgments, estimates and assumptions about the carrying amounts of assets and liabilities that are not readily apparent from other sources. The estimates and associated assumptions are based on historical experience and other factors that are considered to be relevant. Actual results may differ from these estimates.

The estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognized in the period in which the estimate is revised if the revision affects only that period or in the period of the revision and future periods if the revision affects both current and future periods.

​

The significant judgements made by management in applying the Company’s accounting policies, except for the significant judgements related to revenue recognition from milestone payments as further described below and in Note 14, and the key sources of estimation uncertainty were the same as those described in the Company’s annual financial statements for the year ended December 31, 2023.

Revenue recognition for the Eli Lilly collaboration and license agreement

a. Identification of the performance obligation

Note 14 describes the Company’s original research and collaboration agreement with Eli Lilly and Company, and the amended and restated research and collaboration agreement (collectively, the “Collaboration agreement”). Under the Collaboration agreement, ProQR provides Eli Lilly with a license (with a right to sub-license) to exploit compounds resulting from the collaboration. A significant amount of judgement is required to determine whether the license is distinct from the other promises in the contract. The license was concluded not to be distinct from the other promises in the contract based on the following considerations:

ProQR’s services are evaluated as predominant at inception of the contract and contractually only ProQR can perform these services as they are specific to the skills of the Company. The resulting compounds from the collaboration do not represent a series of distinct promises because they were not predetermined at the inception of the contract and can be terminated or replaced at the discretion of Lilly subject to the terms and conditions of the Collaboration agreement.

b. Determining the timing of satisfaction of performance obligations

Under the Collaboration agreement, the Company recognizes revenue over time, using an input method that estimates the satisfaction of the performance obligation as the percentage of labor hours incurred compared to the total estimated labor hours required to complete the promised services. As our estimate of the total labor hours required is dependent on the evolution of the research and development activities, it may be subject to change. If the progression and/or outcome of certain research and development activities would be different from the assumptions that were made during the preparation of these financial statements, this could lead to material adjustments to the total estimated labor hours, which might result in a reallocation of revenue between current and future periods. Our total deferred revenue balance amounts to € 55,588,000 of which € 55,236,000 is related to this Eli Lilly performance obligation at September 30, 2024. As at December 31, 2023 the entire deferred revenue balance of € 64,739,000 related to the Eli Lilly performance obligation.

c. Determining the transaction price

The Company applied judgement to determine whether the equity investments made by Eli Lilly in ProQR are part of the transaction price for the Collaboration agreement. The Company concluded that the differences between the prices that Eli Lilly paid for the shares and the ProQR stock closing prices on the days of entering into the equity investment agreements arose because of the Company’s existing obligations to deliver research and development services to Eli Lilly under the terms of the Collaboration agreement. Therefore, the above differences between the closing share prices on the agreement effective dates and the equity investment prices paid by Eli Lilly are considered to be part of the transaction price of the contract and are initially allocated to deferred revenue.

The contract also includes variable consideration, but no variable consideration was included in the initial transaction price at the inception, as it is not highly probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. The Company includes such variable consideration in the transaction price when the uncertainty associated with the variable consideration is resolved.

As further described in Note 14, during 2024, the Company reached milestones under the agreement, which were added to the transaction price and recognized partially as revenue during 2024 with the remainder recorded in future periods based on progress towards satisfaction of performance obligation.

The Collaboration agreement includes sales-based royalties, including commercial milestone payments based on the level of sales. Related revenue is recognized as the subsequent underlying sales occur at a point in time.

Research and development expenditures

Research expenditures are reflected in the income statement. Development expenses are currently also reflected in the income statement because the criteria for capitalization are not met. At each balance sheet date, the Company estimates the level of service performed by the vendors and the associated costs incurred for the services performed.

Although we do not expect the estimates to be materially different from amounts actually incurred, the understanding of the status and timing of services performed relative to the actual status and timing of services performed may vary and could result in reporting amounts that are too high or too low in any particular period.
