Saudi Arabia’s Capital Market Authority (CMA) said on 29 September 2026 that it had approved amendments to the rules for registering auditors of entities under its supervision. The announcement says the new text took effect upon publication, making this an adopted regulatory change rather than a public consultation. CMA said the amendments aim to improve audit quality and the information disclosed by registered accounting firms. The rules cover registered audit firms carrying out engagements for entities supervised by the Authority.

The new requirements call for a sufficient number of audit managers with membership in the Saudi Organization for Chartered and Professional Accountants (SOCPA), or equivalent professional qualifications accepted by the CMA, in proportion to each firm’s nature, size and variety of work. Firms must also have an appropriate quality-management system for audit and review engagements involving financial statements, and follow professional standards when reviewing interim statements and auditing annual statements. These are requirements reported in the source; they do not establish that individual audit outcomes are necessarily sound.

During CMA inspections, registered firms must cooperate and provide requested information, data and documents. Where inspection findings warrant it, a firm must prepare a corrective-action plan, submit it for approval and implement it if approved. The final inspection results on a listed company’s audit file are also to be shared with that company’s audit committee. Transparency reports must disclose information about a firm’s profile, ownership, governance and leadership, describe its quality-management system, name those overseeing it and state the result of its annual evaluation.

Economically, audit-quality rules and oversight can support investor confidence in published financial information, but a rule change alone cannot eliminate misreporting risk. Building qualified audit-manager capacity and quality systems may create compliance costs; the CMA did not quantify those costs or any effect on audit fees. The actual effect will depend on firms’ access to qualified staff and training, follow-up on inspection findings and the usefulness of transparency disclosures. The announcement verifies the adopted mechanisms; it provides no measured increase in investor confidence and no evidence of a particular firm’s non-compliance.

These disclosures could let investors assess not only a firm’s size but also how quality oversight is organised. Publication and investors’ use of the information in decisions are separate steps; the regulatory announcement does not measure the latter.
