FORWARD-LOOKING STATEMENTS
Certain statements in this Annual Report on Form 40-F and the documents filed as exhibits hereto, including certain
information about Cameco’s business outlook, objectives, strategies, plans, strategic priorities and results of
operations, as well as other statements which are not current statements or historical facts, constitute “forward-
looking information” within the meaning of applicable Canadian securities laws and “forward-looking statements”
within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking information and
statements involve risks, uncertainties and other factors that could cause actual results to differ materially from
those expressed or implied by them. Sentences and phrases containing words such as “anticipate”, “believe”,
“estimate”, “expect”, “forecast”, “goal”, “intend”, “outlook”, “plan”, “potential”, “predict”, “project”, “proposed”,
“scheduled”, “strategy”, “target” and “will,” and the negative of any of these words, or variations of them, or
comparable terminology that does not relate strictly to current or historical facts, are all indicative of forward-looking
information or statements.
3
The forward-looking information and statements included in this Annual Report on Form 40-F (including the
exhibits hereto) represent our views as of the date of such documents and should not be relied upon as
representing our views as of any subsequent date. While we anticipate that subsequent events and developments
may cause our views to change, we specifically disclaim any intention or obligation to update forward-looking
information and statements, whether as a result of new information, future events or otherwise, except to the
extent required by applicable securities laws. Forward-looking information and statements contained in this
Annual Report on Form 40-F about prospective results of operations, financial position or cash flows that are
based upon assumptions about future economic conditions and courses of action are presented for the purpose
of assisting our security holders in understanding management’s current views regarding those future outcomes,
and may not be appropriate for other purposes.
See Cameco’s Annual Information Form for the year ended December 31, 2025, attached as Exhibit 99.1 to this
Annual Report on Form 40-F, under the heading “Caution about forward-looking information”, and Cameco’s
management’s discussion and analysis for the year ended December 31, 2025, attached as Exhibit 99.3 to this
Annual Report on Form 40-F, under the heading “Caution about forward-looking information”, for additional
information regarding forward-looking statements.
Certifications and Disclosure Regarding Controls and Procedures
.
(a)
Certifications regarding controls and procedures
.
(b)
Evaluation of disclosure controls and procedures
. As of December 31, 2025, an evaluation of the
effectiveness of Cameco Corporation’s “disclosure controls and procedures” (as such term is defined in
Rules 13a-15(e) and 15d-15(e) of the United States Securities Exchange Act of 1934, as amended (the
“Exchange Act”)) was carried out by Cameco Corporation’s Chief Executive Officer (“CEO”) and Chief
Financial Officer (“CFO”). Based on that evaluation, the CEO and CFO have concluded that as of such
date Cameco Corporation’s disclosure controls and procedures were effective to provide a reasonable
level of assurance that information required to be disclosed by Cameco Corporation in reports that it
files or submits under the Exchange Act is recorded, processed, summarized and reported within the
time periods specified in United States Securities and Exchange Commission (the “Commission”) rules
and forms.
(c)
Management’s annual report on internal control over financial reporting
.
Company, including the CEO and CFO, is responsible for establishing and maintaining adequate
“internal control over financial reporting”, as that term is defined in Rules 13a-15(f) and 15d-15(f) under
the Exchange Act, for Cameco Corporation. Management conducted an evaluation of the effectiveness
of internal control over financial reporting based on criteria established in Internal Control – Integrated
Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.
Based on that evaluation, management concluded that Cameco Corporation’s internal control over
financial reporting was effective as of December 31, 2025.
It should be noted that while the CEO and CFO believe that Cameco Corporation’s disclosure controls
and procedures and internal control over financial reporting provide a reasonable level of assurance that
they are effective, they do not expect such disclosure controls and procedures or internal control over
financial reporting to be capable of preventing or detecting all errors and fraud. A control system, no
matter how well conceived or operated, can provide only reasonable, not absolute, assurance that the
objectives of the control system are met.
(d)
Attestation report of the registered public accounting firm
.
Corporation’s internal control over financial reporting as of December 31, 2025, was audited by KPMG
LLP, an independent registered public accounting firm, as stated in its report, which accompanies the
Cameco 2025 Consolidated Audited Financial Statements that are filed as Exhibit 99.2 to this Annual
Report on Form 40-F.
4
(e)
Changes in internal control over financial reporting
. During the fiscal year ended December 31,
2025, there was no significant change in Cameco Corporation’s internal control over financial reporting
that materially affected, or is reasonably likely to materially affect, Cameco Corporation’s internal control
over financial reporting. In April 2024, Cameco Corporation implemented SAP S/4 HANA, an enterprise
resource planning system, across the entire organization. As a result of this implementation, Cameco
Corporation modified certain existing internal controls and implemented new controls and procedures.
The implementation process included extensive involvement by key end users and required significant
pre-implementation planning, design, and testing. Cameco Corporation continues to evaluate and
monitor its internal controls and make changes as required and believes it is taking the necessary steps
to maintain appropriate internal controls over financial reporting during this period of change.
Audit & Finance Committee Financial Expert
.
least three members of its audit and finance committee (the “audit committee”) are audit committee financial experts.
The audit committee financial experts are Daniel Camus, Marie Inkster and Leontine van Leeuwen-Atkins. Mr.
Camus, Ms. Inkster and Ms. van Leeuwen-Atkins have each been determined by Cameco Corporation’s board of
directors to be an independent director as such term is defined under the Canadian Securities Administrators’
National Instrument 52-110 (Audit Committees) (“NI 52-110”), the Commission’s audit committee independence
requirements, and the rules of the New York Stock Exchange (the “NYSE”) relating to the independence of audit
committee members.
Information concerning the relevant experience of Mr. Camus, Ms. Inkster and Ms. van Leeuwen-Atkins is included
in their biographical information contained in Cameco Corporation’s Annual Information Form that is filed as Exhibit
99.1 to this Annual Report on Form 40-F. The Commission has indicated that the designation of a person as an
audit committee financial expert does not make such person an “expert” for any purpose, impose any duties,
obligations or liability on such person that are greater than those imposed on members of the audit committee and
board of directors who do not carry this designation, or affect the duties, obligations or liability of any other member
of the audit committee or the board of directors.
