forward-looking statements regulatory

"This Notice to the Market may contain forward-looking statements."

Forward-looking statements are predictions or plans that companies share about what they expect to happen in the future, like estimating sales or profits. They matter because they help investors understand a company's outlook, but since they are based on guesses and assumptions, they can sometimes be wrong.

consolidated financial statements financial

"to provide audit services for the Company's consolidated financial statements and quarterly"

Consolidated financial statements combine the financial results of a parent company and all the companies it controls into one set of reports, like showing the whole family’s budget instead of each person’s separate accounts. For investors this matters because it gives a complete picture of assets, debts, revenue and cash flow across the entire group, helping assess true size, risk and profitability without missing or double-counting related activity.

shareholding structure financial

"in the context of the change in its shareholding structure and the implementation"
