CSRD for Private Equity: Portfolio Reporting After Omnibus

If you run ESG for a mid-market fund, the Omnibus changed your problem rather than removing it. Most of your portfolio companies are now outside CSRD. Your LPs still send questionnaires, your lenders still have sustainability KPIs in the facility agreement, your SFDR disclosures still need underlying data, and the larger customers of your companies still ask for numbers.

What you lose is the forcing function. When CSRD was going to cover most mid-sized companies, the regulation set the standard and the deadline. Now the fund has to set both, across twelve companies in five countries, with nothing to point to except your own request.

This guide covers what to collect, from whom, and how to staff it. The short version: use the VSME as the portfolio standard, let LP and lender requests decide what you add to it, and keep full CSRD work for the few holdings that are still above the thresholds.

Which Portfolio Companies Still Report

Directive (EU) 2026/470, the Omnibus I amendment, was published in February 2026 and entered into force in March. For EU companies, CSRD now applies only above both 1,000 employees and €450 million net turnover. Member States have until March 2027 to transpose it.

Two practical points for a fund:

• Test each holding on its own numbers. The tests apply at the level of the individual company, or on a consolidated basis for a parent. A platform with add-ons can cross the line even if no single subsidiary would.
• Check the parent, not just the operating company. A holding owned through a non-EU structure has its own rules, which are covered in our guide to CSRD for non-EU companies.

We don't restate the threshold tables here. The Omnibus simplification guide has them, and the CSRD timeline has the reporting years. For this guide, assume a typical portfolio ends up with a small group of holdings that report under CSRD, and a large group that does not.

Why You Still Need the Data

Leaving CSRD does not make the questions stop. Four sources keep asking.

LP questionnaires. Many LPs ask for the ESG Data Convergence Initiative (EDCI) metrics, a short, standardised set of portfolio company data points that the initiative reviews each year and extends occasionally. The most recent changes added items such as net zero targets and cybersecurity. The current list and guidance are published at esgdc.org; collect against the version for your reporting year, not one copied from last year's side letter.

SFDR. If your fund is classified under Article 8 or Article 9, you disclose sustainability information at product level, including principal adverse impact indicators, and the underlying data comes from the companies. SFDR is in flux: in November 2025 the Commission proposed a revised regime that would replace the current Article 8 and 9 classifications with new categories. That is a proposal, not law, so plan around the current disclosures and keep your data set broad enough to survive the change.

Lenders. Sustainability-linked loans and ESG margin ratchets carry KPIs that the company must report and, increasingly, have verified. These are specific to each facility and usually the most contractually serious of the four.

In-scope customers. A portfolio company that sells to a large CSRD reporter will get value-chain data requests. Our value chain reporting guide covers the mechanics. What matters for the fund is the limit: companies with up to 1,000 employees can decline requests that go beyond the voluntary standard, with an exception for information commonly shared in their sector. A portfolio company that already reports on that standard can answer most requests with a document it already has.

If your fund reports Taxonomy alignment, the EU Taxonomy alignment guide covers the KPIs that sit alongside this data.

The VSME as a Portfolio Baseline

The VSME is EFRAG's voluntary sustainability reporting standard for small and medium-sized companies. The Commission recommended it in July 2025 as a voluntary standard for non-listed SMEs. The Omnibus then built on it: the Directive provides for a voluntary standard to be fixed by delegated act, based on the VSME and covering companies up to 1,000 employees. The Commission has moved to adopt that act, and its content may differ in places from the original VSME. Check the current text before you hard-code module names into templates. For the basics of the standard itself, see our SME compliance guide.

Why it works as a portfolio standard:

• One module set, comparable across companies. A basic module for everyone, plus a broader module where the company or the fund needs more. You can compare a Polish manufacturer with a Dutch software company on the same page.
• It is proportionate. Small teams can complete it. A standard written for listed groups tends to produce a half-filled workbook and a stalled project.
• It defines the ceiling for in-scope customers. A holding that reports on it has a ready answer to value-chain requests, and a basis for declining anything beyond it.
• It is not your whole data set. The VSME will not cover every EDCI item, every SFDR indicator or every lender KPI. Treat it as the base layer and add a short fund-level annex for the items it misses.

One discipline is worth setting at the start: map each stakeholder request to the base layer once, at fund level. Do that mapping one time, and every holding gets a single template instead of five overlapping questionnaires. It is the biggest time saver in the whole exercise, and the part that most funds do last.

Timing It to the Hold Period

Reporting works best when it hangs on moments the deal team already has.

• Entry diligence. Collect a baseline: the VSME basic module, whether the company is above or below the CSRD thresholds, and any customer or lender data commitments already in place. This also flags the holdings that will need more than the standard.
• The 100-day plan. Agree the template, the owner at the company, the data calendar and who pays. Fix the reporting boundary and the year-one gaps while the management team is still in onboarding mode.
• Annual data. Align the collection window with the annual accounts rather than a separate cycle. Companies that report ESG data once, at year end, with the finance team, produce better numbers than those asked quarterly.
• The exit data room. Buyers now ask for ESG data in diligence. Three years of consistent figures on one standard is far easier to put in a data room than three different formats. Start thinking about this in year two, not in the sale process.

Writing It into the Deal

Obligations that live only in an email from the ESG team tend to lapse at the first change of management. The more reliable route is the deal documents. Three kinds of provision do most of the work. This is a description of what they cover, not drafting; your counsel writes the wording.

• A reporting covenant. The company agrees to deliver an annual ESG data set, on a named standard and template, by a set date after year end.
• An information right. The fund can ask for the underlying data and supporting evidence, and reasonable access to the people who produced it. This matters when an LP or lender asks a follow-up question.
• A cost-allocation term. Who pays for data collection, who pays for any verification, and what happens if the fund changes the template.

For existing holdings, where the documents are already signed, the practical route is usually a side letter or an amendment bundled with another change, plus a clear explanation of why the request is proportionate. Companies that see the data as something they can reuse for customers and lenders resist less.

Staffing It: a Fund Lead Plus Local Experts

Portfolio ESG reporting splits into two jobs, and they need different people.

Fund-level work. Choose the standard, map it to LP, lender and SFDR requests, build the template, set the calendar, and consolidate. This is one person's job, and it needs someone who knows how funds work, who can read an SFDR disclosure and an LP questionnaire, and who can say no to a request that doesn't earn its place. Often this is a senior adviser on a retainer, or a fractional lead. Our guide to consultant engagement models covers how to buy that, and what to put in the scope.

Company-level work. Help each management team collect, check and submit the data. It is local: language, local data sources, national rules for reporting and, where relevant, how assurance works in that country. A single adviser covering five countries will be thinner in each of them than a local expert would be.

A fund that has twelve companies in five countries is usually better served by one fund lead and local experts in each country than by one firm trying to do everything. The coordination cost is small if the fund lead owns the template, and the quality gain at company level is large.

This is where a directory helps. Filter by country for the company-level work, and by SFDR, Taxonomy or VSME experience for the fund lead. Check each person's actual sector and fund experience, not just the label, and ask for one reference from a similar portfolio exercise.

A Practical First Quarter

If you are starting from nothing, a workable sequence is:

1. List every holding with its country, headcount, turnover and customer base, and mark the ones that may be in CSRD scope.
2. Map the requests you actually receive from LPs, lenders and SFDR to a single data list.
3. Choose the VSME modules for the base layer and add a short fund-level annex.
4. Appoint the fund lead, then one local expert per country that has more than one or two holdings.
5. Pilot with three companies in different countries before rolling out to everyone.

Pilot first. Two or three companies will show you where the template breaks, whether the definitions survive translation, and how long collection really takes, before twelve companies find out at once.

Find the People for Your Portfolio

Staffing is the slowest step, and the one most funds leave until the first LP deadline. Browse CSRD consultants for Financial Services and filter by the countries where you hold companies. Look for people with SFDR, EU Taxonomy or VSME experience for the fund-level role, and local experts for each market.
