Certificate 
 This Warrant Certificate certifies that , or registered assigns, is the registered holder of warrant(s) evidenced hereby
(the “Warrants” and each, a “Warrant”) to purchase Class A ordinary shares, $0.0001 par value (the “Class A ordinary share(s)”), of
Austerlitz Acquisition Corporation I, a Cayman Islands exempted company (the “Company”). Each Warrant entitles the holder, upon exercise during the period set forth in the Warrant Agreement referred to below, to receive from
the Company that number of fully paid and non-assessable Class A ordinary shares as set forth below, at the exercise price (the “Exercise Price”) as determined pursuant to the
Warrant Agreement, payable in lawful money (or through “cashless exercise” as provided for in the Warrant Agreement) of the United States of America upon surrender of this Warrant Certificate and payment of the Exercise Price
at the office or agency of the Warrant Agent referred to below, subject to the conditions set forth herein and in the Warrant Agreement. Defined terms used in this Warrant Certificate but not defined herein shall have the meanings given to them in
the Warrant Agreement. 
 Each whole Warrant is initially exercisable for one fully paid and non-assessable
Class A ordinary share. No fractional shares will be issued upon exercise of any Warrant. If, upon the exercise of Warrants, a holder would be entitled to receive a fractional interest in a Class A ordinary share, the Company will, upon
exercise, round down to the nearest whole number the number of Class A ordinary shares to be issued to the Warrant holder. The number of Class A ordinary shares issuable upon exercise of the Warrants is subject to adjustment upon the
occurrence of certain events as set forth in the Warrant Agreement. 
 The initial Exercise Price per Class A ordinary share for any Warrant is equal
to $11.50 per share. The Exercise Price is subject to adjustment upon the occurrence of certain events set forth in the Warrant Agreement. 
 Subject to the
conditions set forth in the Warrant Agreement, the Warrants may be exercised only during the Exercise Period and to the extent not exercised by the end of such Exercise Period, such Warrants shall become void. The Warrants may be redeemed, subject
to certain conditions, as set forth in the Warrant Agreement. 
 Reference is hereby made to the further provisions of this Warrant Certificate set forth on
the reverse hereof and such further provisions shall for all purposes have the same effect as though fully set forth at this place. 
 This Warrant
Certificate shall not be valid unless countersigned by the Warrant Agent, as such term is used in the Warrant Agreement. 
 This Warrant Certificate shall
be governed by and construed in accordance with the internal laws of the State of New York, without regard to conflicts of laws principles thereof.

 The Warrants evidenced by this Warrant
Certificate are part of a duly authorized issue of Warrants entitling the holder on exercise to receive Class A ordinary shares and are issued or to be issued pursuant to a Warrant Agreement dated as of
        , 2021 (the “Warrant Agreement”), duly executed and delivered by the Company to Continental Stock Transfer & Trust Company, a New York corporation, as warrant agent
(the “Warrant Agent”), which Warrant Agreement is hereby incorporated by reference in and made a part of this instrument and is hereby referred to for a description of the rights, limitation of rights, obligations, duties and
immunities thereunder of the Warrant Agent, the Company and the holders (the words “holders” or “holder” meaning the Registered Holders or Registered Holder, respectively) of the Warrants. A copy of
the Warrant Agreement may be obtained by the holder hereof upon written request to the Company. Defined terms used in this Warrant Certificate but not defined herein shall have the meanings given to them in the Warrant Agreement. 

Warrants may be exercised at any time during the Exercise Period set forth in the Warrant Agreement. The holder of Warrants evidenced by this Warrant
Certificate may exercise them by surrendering this Warrant Certificate, with the form of election to purchase set forth hereon properly completed and executed, together with payment of the Exercise Price as specified in the Warrant Agreement (or
through “cashless exercise” as provided for in the Warrant Agreement) at the principal corporate trust office of the Warrant Agent. In the event that upon any exercise of Warrants evidenced hereby the number of Warrants exercised shall be
less than the total number of Warrants evidenced hereby, there shall be issued to the holder hereof or his, her or its assignee, a new Warrant Certificate evidencing the number of Warrants not exercised. 

Notwithstanding anything else in this Warrant Certificate or the Warrant Agreement, no Warrant may be exercised unless at the time of exercise (i) a
registration statement covering the issuance of the Class A ordinary shares to be issued upon exercise is effective under the Securities Act and (ii) a prospectus thereunder relating to the Class A ordinary shares is current, except
through “cashless exercise” as provided for in the Warrant Agreement. 
 The Warrant Agreement provides that upon the occurrence of certain events
the number of Class A ordinary shares issuable upon exercise of the Warrants set forth on the face hereof may, subject to certain conditions, be adjusted. If, upon exercise of a Warrant, the holder thereof would be entitled to receive a
fractional interest in a Class A ordinary share, the Company shall, upon exercise, round down to the nearest whole number of Class A ordinary shares to be issued to the holder of the Warrant. 

Warrant Certificates, when surrendered at the principal corporate trust office of the Warrant Agent by the Registered Holder thereof in person or by legal
representative or attorney duly authorized in writing, may be exchanged, in the manner and subject to the limitations provided in the Warrant Agreement, but without payment of any service charge, for another Warrant Certificate or Warrant
Certificates of like tenor evidencing in the aggregate a like number of Warrants. 
 Upon due presentation for registration of transfer of this Warrant
Certificate at the office of the Warrant Agent a new Warrant Certificate or Warrant Certificates of like tenor and evidencing in the aggregate a like number of Warrants shall be issued to the transferee(s) in exchange for this Warrant Certificate,
subject to the limitations provided in the Warrant Agreement, without charge except for any tax or other governmental charge imposed in connection therewith. 

The Company and the Warrant Agent may deem and treat the Registered Holder(s) hereof as the absolute owner(s) of this Warrant Certificate (notwithstanding any
notation of ownership or other writing hereon made by anyone), for the purpose of any exercise hereof, of any distribution to the holder(s) hereof, and for all other purposes, and neither the Company nor the Warrant Agent shall be affected by any
notice to the contrary. Neither the Warrants nor this Warrant Certificate entitles any holder hereof to any rights of a shareholder of the Company.
