Why this matters in Saudi Arabia
If you follow Saudi listed companies, you see the word constantly: a result, a contract, a board change is "announced on Efsah." It is worth knowing exactly what that means, because Efsah is not a press wire or a company website. It is the formal channel that makes a disclosure official — and the moment a company uses it is the moment information stops being private.
What Efsah is
Efsah is the electronic disclosure platform, operated through Tadawul, that listed companies use to publish their official announcements to the market. When a company has something it must tell investors — a quarterly result, a material development, a change in its board — it publishes that announcement on Efsah. The platform distributes it to the whole market at the same time, so no investor learns it before another through the official channel.
Think of the three institutions together: the CMA makes the rules, Tadawul runs the market, and Efsah is how the company tells it. If an announcement did not go out on Efsah, the market has not formally been told.
What goes on Efsah
A listed company's Efsah announcements cover the range of its disclosure obligations: periodic financial statements, material developments in its sphere of activity, changes to the board and senior executives, changes in substantial shareholdings above defined thresholds, and the other notifications the rules require. For Main Market issuers, these announcements are bilingual — Arabic and English, identical in substance, with the Arabic controlling in any conflict.
Why the channel is the line
The reason Efsah matters so much is what it does to the status of information. Until a disclosure is published on Efsah, the information is inside information: it sits inside the company, access to it must be controlled, and the people who hold it cannot trade on it. Publishing on Efsah is the act that moves that information into the public domain, where the whole market can act on it equally.
This is why timing and channel are not administrative details. A company that lets material information reach some investors before it reaches Efsah — through a selective briefing, a leak, an early distribution of results — has created an uneven playing field, and that is exactly what the disclosure regime exists to prevent. The discipline is simple to state: nothing material reaches anyone outside the company before it reaches everyone, through Efsah, at once. The strongest issuers treat that line as absolute.
