Where do I find the dates of future public company filings in France and Germany?

I’m looking for open data sets of some public company data for Germany and France. And in particular I’d reallty appreciate pointers to the answers for the following question:

Is there any centralised source that lists the dates of the AGMs of publicly traded companies, or when they last filed their management accounts?

That is also open data?

I’ll try giving an examaple of what I’m after.

Aviva as an example

There’s noting particularly special about Aviva here – just that they’re large, probably active in Europe, and probably large enough to be an organisation covered by the Corporate Sustainability Reporting Directive in Europe.

Aviva is listed here on UK Companies House website, and there is this helpful line:

Next accounts made up to 31 December 2024 due by 30 June 2025″

Here’s the screenshot:

What I care about is the date of the next report, because that gives us an idea of when you might see an CSRD report published by the org.

The CSRD is a big important law in Europe, and I’d like to create an open dataset of every large company that needs to report against the CSRD, and when they’re are likely to report in 2025.

What is the equivalent of a nice, easy to use Companies house style site for France and Germany?

Is there anything you can use without having to cough up a bunch of cash to buy some dataset?

I’d welcome pointers, as I’m less familiar with the open data scenes of France and Germany than I am with the UK.

Right now, my guess best guess is Open Corproates, who have a fairly good entry on Aviva too.
