Entry into a Material Definitive Agreement
Underwriting Agreement
On June 25, 2026, ProQR Therapeutics
N.V. (the “Company”) entered into an underwriting agreement (the “Underwriting Agreement”) with BofA Securities,
Inc., Evercore Group L.L.C. and Cantor Fitzgerald & Co., as representatives of the several underwriters named therein (collectively,
the “Underwriters”), relating to an underwritten registered direct offering (the “Offering”) of 27,624,310 ordinary
shares (the “Shares”) of the Company. The offering price of the Shares to the investors was $1.81 per share (the “Offering
Price”), and the Underwriters agreed to purchase the Shares from the Company pursuant to the Underwriting Agreement at the Offering
Price, less underwriting discounts and commissions.
The Shares were issued pursuant
to the Company’s shelf registration statement (the “Registration Statement”) on Form F-3 (Registration Statement No.
333-282419) previously filed with the Securities and Exchange Commission (the “Commission”) on September 30, 2024 and declared
effective by the Commission on October 10, 2024. The Offering was made only by means of a prospectus supplement, along with a base prospectus,
that form a part of the Registration Statement. The closing of the Offering is expected to occur on June 26, 2026, subject to the satisfaction
of customary closing conditions.
The aggregate net proceeds
from the Offering were approximately $46.5 million, after deducting the underwriting discounts and commissions and estimated offering
expenses payable by the Company.
The Underwriting Agreement
contains customary representations and warranties, agreements and obligations, conditions to closing and termination provisions. The
Underwriting Agreement provides for indemnification by the Underwriters of the Company, its directors and certain of its executive officers,
and by the Company of the Underwriters, for certain liabilities, including liabilities arising under the Securities Act of 1933, as amended
(the “Securities Act”), and affords certain rights of contribution with respect thereto.
The foregoing description
of the Underwriting Agreement is qualified in its entirety by reference to the Underwriting Agreement, a copy of which is attached as
Exhibit 1.1 hereto and incorporated by reference herein. The representations, warranties and covenants contained in the Underwriting
Agreement were made only for purposes of such agreements and as of specific dates, were solely for the benefit of the parties to such
agreement, and may be subject to limitations agreed upon by the contracting parties.
A copy of the legal opinion
of Allen Overy Shearman Sterling LLP, the Company’s Netherlands counsel, relating to the legality and validity of the Shares is
filed as Exhibit 5.1 to this Report of Foreign Private Issuer on Form 6-K, which is filed with reference to, and is hereby incorporated
by reference into, the Registration Statement.
Share Purchase Agreement
Concurrently with the Offering,
the Company entered into a Share Purchase Agreement (the “Share Purchase Agreement”) with Eli Lilly and Company (“Lilly”)
on June 25, 2026, in a separately negotiated transaction pursuant to which the Company agreed to offer and sell to Lilly, and Lilly has
agreed to purchase, 5,100,780 ordinary shares of the Company (the “Lilly Shares”) at a price per share equal to the Offering
Price, for an aggregate purchase price of approximately $9.2 million (the “Private Placement”). The closing of the Private
Placement is expected to occur on June 26, 2026, subject to the consummation of the Offering and the satisfaction of other customary
closing conditions.
The Share Purchase Agreement
contains customary representations, warranties, and covenants of each party. Pursuant to the terms of the Share Purchase Agreement, Lilly
may not, subject to certain limited exceptions, dispose of any of the Lilly Shares for a period commencing on the Closing Date (as defined
therein) until the earlier of (i) the date that is six (6) months after the Closing Date and (ii) the date that the Amended and Restated
Collaboration Agreement (as defined therein) is terminated. Additionally, under the Share Purchase Agreement, Lilly may participate in
certain public offerings or private placements of the Company’s ordinary shares, subject to share ownership requirements and other
limitations set forth in the Share Purchase Agreement. The Company has also granted Lilly certain customary registration rights with
respect to the Lilly Shares, including registering such shares for resale on or prior to the expiration of the lockup agreement described
above. Lilly has also agreed to a standstill on acquiring additional shares of the Company and proposing certain transactions to the
Company or its shareholders, all on the terms, and subject to the exceptions, contained in the Share Purchase Agreement.
The foregoing description
of the Share Purchase Agreement is qualified in its entirety by reference to the Share Purchase Agreement, a copy of which is attached
as Exhibit 10.1 hereto and incorporated by reference herein. The representations, warranties and covenants contained in the Share Purchase
Agreement were made only for purposes of such agreements and as of specific dates, were solely for the benefit of the parties to such
agreement, and may be subject to limitations agreed upon by the contracting parties.
Unregistered Sale of Equity Securities
As
described in the section titled “Share Purchase Agreement” in this Report of Foreign Private Issuer on Form 6-K, which
is incorporated in this section by reference, the Lilly Shares were issued in a private placement exempt from registration pursuant to
Section 4(a)(2) of the Securities Act, or Regulation D promulgated thereunder, as a transaction by an issuer not involving a public offering.
The Company relied on this exemption from registration based in part on the representations made by Lilly, including that it was acquiring
the Lilly Shares for the purpose of investment and not with a view to resale or distribution of any part thereof in violation of the
Securities Act, and an appropriate legend will be applied to the Lilly Shares. The Lilly Shares have not been registered under the Securities
Act or any state securities laws and may not be offered or sold in the United States absent registration under the Securities Act or
an applicable exemption from the registration requirements.
Other Events
On June 25, 2026, the Company
issued a press release announcing the Offering and Private Placement. A copy of the press release is attached as Exhibit 99.1 hereto
and is hereby incorporated by reference herein.
The Company hereby incorporates
by reference the information contained herein into the Company’s registration statements on Form F-3 (File No. 333-282419,

ProQR Prices $50.0 Million Underwritten Registered
Direct Offering and Concurrent Private Placement
LEIDEN, Netherlands and CAMBRIDGE, Mass.,
June 25, 2026 -- ProQR Therapeutics N.V. (Nasdaq: PRQR) (“ProQR”), a clinical-stage biotechnology company dedicated to changing
lives through transformative RNA therapies based on its proprietary Axiomer™ RNA editing technology platform, today
announced the pricing of an underwritten registered direct offering of 27,624,310 ordinary shares (the “Offering”) at an
offering price of $1.81 per share (the “Offering Price”), for total gross proceeds of approximately $50.0 million, before
deducting underwriting discounts and commissions and other offering expenses payable by ProQR.
Concurrently with the Offering, ProQR has entered
into a share purchase agreement with Eli Lilly and Company (“Lilly”), one of its existing shareholders and a strategic partner,
in a separately negotiated transaction pursuant to which ProQR agreed to offer and sell, and Lilly agreed to purchase, 5,100,780 ordinary
shares, to permit Lilly to maintain its pro rata beneficial ownership, at the Offering Price, for total gross proceeds of approximately
$9.2 million, subject to the consummation of the Offering and the satisfaction of other customary closing conditions. The sale of ordinary
shares to Lilly in the concurrent private placement will not be registered as part of the Offering. The closing of the Offering is not
contingent upon the closing of the concurrent private placement. The ordinary shares purchased in the concurrent private placement will
not be subject to any underwriting discounts or commissions.
The ordinary shares to be sold in the concurrent
private placement are being issued pursuant to the exemptions provided by Section 4(a)(2) of the Securities Act of 1933, as amended (the
“Securities Act”). These shares have not been registered under the Securities Act, or any state or other applicable jurisdiction’s
securities laws, and may not be offered or sold in the United States absent registration or an applicable exemption from the registration
requirements of the Securities Act and applicable state or other jurisdiction’s securities laws.
ProQR currently intends to use the net proceeds
from the Offering and the concurrent private placement, together with its existing cash and cash equivalents, primarily to fund research
and clinical development of its current or additional pipeline candidates and for working capital, capital expenditures and other general
corporate purposes.
BofA Securities, Evercore ISI and Cantor are
acting as joint lead bookrunning managers for the Offering, and Oppenheimer & Co. is acting as a bookrunning manager for the Offering.
The Offering and concurrent private placement are expected to close on or about June 26, 2026, subject to the satisfaction of customary
closing conditions.
A shelf registration statement on Form F-3 relating
to the Offering (including the accompanying prospectus) was filed with the Securities and Exchange Commission (the “SEC”)
on September 30, 2024 and was declared effective on October 10, 2024. The Offering is being made only by means of a prospectus and prospectus
