Rules on the Offer of Securities and Continuing Obligations (OSCO)
Structure, Scope, and Key Provisions of the Primary Disclosure Framework
First: Introduction
The Rules on the Offer of Securities and Continuing Obligations (OSCO) are the cornerstone document governing continuous disclosure in the Saudi capital market. Issued by the Capital Market Authority through Board Resolution 3-123-2017 dated 9/4/1439H (27/12/2017G), OSCO unified previously scattered disclosure requirements into a comprehensive framework. The Rules cover both the initial offering of securities (prospectuses, IPOs, secondary offerings) and the continuing obligations of issuers (ongoing disclosures throughout the listing). This article focuses on the continuing obligations portion, which forms the backbone of the continuous disclosure regime.
OSCO has been amended several times since its issuance — most notably in 2019 (cross-listing framework), 2022 (refinements), 2023 (alignment with new Companies Law), 2024 (Resolution 3-114-2024), and 2025 (Resolution 1/53/2025 adding Saudi Depositary Receipts). Understanding OSCO is essential for any listed company, board member, or compliance professional. This article provides a comprehensive review of the Rules’ structure, scope, key provisions, and recent amendments.
| 💡 Key Insight OSCO is not a static document — it is a living regulatory framework that has evolved through six rounds of amendments in eight years. This pace reflects the rapid maturation of the Saudi capital market and its alignment with international best practices. Companies that treat OSCO as a one-time learning project will fall behind; those who track amendments continuously and integrate updates promptly will stay ahead. |

Companies that excel in OSCO compliance share common characteristics: comprehensive policies, qualified disclosure officers, strong technology systems, continuous training, and a culture that values transparency. These companies don’t just comply — they leverage disclosure as a strategic asset that builds investor trust, attracts capital, and supports long-term value creation. As OSCO continues to evolve through 2026 and beyond, with expected developments in sustainability, climate, and digital disclosures, the companies that invest now in disclosure excellence will lead the next phase of the Saudi capital market’s growth.
