EIC Fund Investment Guidelines: What Changed Between 2023 and 2026

The EIC Fund Investment Guidelines govern how the equity component of the EIC Accelerator blended finance is implemented, from the initial due diligence through to exit. The document published in August 2026 replaces the version that had been in force since late 2023. While the overall architecture of the fund is unchanged, several revisions alter the practical terms that affect startups and Small- and Medium-Sized Enterprises (SMEs) waiting on investment decisions, co-investors negotiating alongside the fund, and professional writers and consultants advising applicants on what to expect after a funding recommendation.

This article sets out every meaningful change between the two versions, clause by clause, with the relevant numbers and language quoted directly. Where a change affects how a company should prepare for the investment process, that is noted. For the full clause-by-clause walkthrough of the 2026 guidelines as a standalone document, see EIC Fund Investment Guidelines 2026: The Full Rulebook Behind Your Equity Component. For a summary of the 2023 version, see EIC Fund Investment Guidelines Summary and Investment Buckets.

Summary of All Material Changes

Maximum Investment Doubled

The single most consequential number in the guidelines is the per-company investment range. The 2023 version stated that the Compartment's investment would range between €500,000 and €15,000,000. The 2026 version raises the ceiling to €30,000,000. Both versions include a caveat that the applicable EIC Work Programme may provide for a higher amount in specific cases, and the maximum for any individual company must be authorised ex ante through a Commission award decision.

This doubling reflects the introduction of the EIC STEP Scaleup instrument, which targets larger investment tickets for companies scaling strategic technologies. For applicants under the standard EIC Accelerator, the practical ceiling may remain around €15,000,000, but companies selected under STEP calls can now receive up to €30,000,000 of direct equity or quasi-equity from the fund within the terms of the guidelines themselves.

The Scope of "EU Interests" Broadened

Throughout the 2023 guidelines, the protection mandate was framed as safeguarding "European interests in strategic areas." The 2026 version systematically replaces this with "EU interests," dropping the "strategic areas" qualifier entirely. The change appears in every clause where the Commission may condition its award on investment safeguards, in the description of blocking-minority powers, in the follow-on investment conditions, and in the exit provisions.

The practical significance is that the Commission's ability to trigger investment safeguards is no longer explicitly tied to a strategic-area designation. Under the 2023 framing, a Commission award decision would identify a specific strategic area to justify the safeguard. Under the 2026 framing, the decision needs only to identify a need to protect EU interests, which is a broader basis. Companies should expect that the set of cases where the Fund acquires a blocking minority or exercises pre-emption rights could expand beyond what was historically classified as strategic technology.

Defence and Weapons: From Broad Exclusion to Narrow Prohibition

This is the change that most visibly reflects a shift in EU policy direction.

The 2023 guidelines included in their excluded activities list: "ammunition and weapons, military/police equipment or infrastructure, with the exception of dual use items as defined in Article 2(1) of Regulation No 428/2009." This was a broad prohibition that excluded most defence-sector companies from EIC Fund investment, with only a dual-use carve-out.

The 2026 guidelines remove that entire line item. In its place, a new exclusion appears at the end of the list: "actions for the development of lethal autonomous weapons without the possibility for meaningful human control over selection and engagement decisions when carrying out strikes against humans, without prejudice to the possibility of providing funding for actions for the development of early warning systems and countermeasures for defensive purposes."

The difference in scope is substantial. Under the 2023 rules, a company developing conventional military hardware, police equipment, or ammunition was excluded unless its product qualified as dual-use. Under the 2026 rules, the only weapons-related exclusion is lethal autonomous weapons that operate without meaningful human control. Defence technology companies developing conventional weapons systems, military communications, armour, surveillance, or any other military application with human control over engagement decisions are no longer excluded from EIC Fund investment. The explicit carve-out for early warning systems and defensive countermeasures reinforces this opening.

This change aligns the investment guidelines with the broader adjustments made to the EIC Work Programme 2026, which itself opened the door to defence-related applications following the EU's increased focus on economic and defence sovereignty.

TRL Flexibility

The 2023 guidelines contained a specific statement: "The EIC Accelerator supports innovators and entrepreneurs. Starting at the earliest at TRL 5 down to TRL 9, the support aims at bringing their innovation to market deployment and scale-up." The grant component was explicitly tied to "TRL 5 to 8 activities."

The 2026 version replaces both references with a delegation: "Adding to a grant component for activities at the TRL levels set out in the applicable EIC Work Programme." Milestones are still defined by reference to TRLs achieved, but the guidelines no longer fix TRL 5 as a minimum or TRL 8 as the grant boundary. This allows the Work Programme to set different TRL ranges for different calls or instruments without requiring a revision of the investment guidelines themselves.

Follow-On Investments: Conditions Loosened

The 2023 guidelines stated that follow-on investments "will only be possible in the following exceptional categories of cases," and then listed two: where a follow-on is necessary to secure a blocking minority or majority to protect European interests in strategic areas, and where subsequent funding rounds would not proceed or would proceed at less favourable terms without the Fund's participation. Both conditions had to be met alongside a requirement for an ex ante amending award decision.

The 2026 version retains the requirement for an ex ante amending award decision by the Commission and requires that the company remain eligible for EIC Accelerator support, but it does not restrict follow-ons to the two exceptional categories. The general conditions still apply: follow-ons must not crowd out smaller investments, the recipient must still be an SME or small mid-cap, continued EIC support must be necessary, InvestEU support must not yet be possible, state aid rules must be respected, and budget must be available. But the removal of the "exceptional categories" gate means the Fund has broader discretion to participate in subsequent rounds, which could be significant for companies that need continued public co-investment to close growth rounds.

Intellectual Property: Exemption Removed

The 2023 guidelines contained a significant carve-out: "EIC Accelerator operations will be exempted from Horizon Europe obligations on intellectual property except: if no investment component is awarded; or if no investment agreement is concluded; or if the operation is terminated by anticipation during the lifetime of the grant component." In other words, companies receiving both grant and equity were exempted from the standard Horizon Europe IP rules (Articles 38 to 41 of the Horizon Europe Regulation), which include obligations around open access, exploitation, and dissemination of results.

The 2026 guidelines remove this exemption entirely. The new language states: "Grant-only support and the grant component of blended finance under the EIC Accelerator shall be subject to the Horizon Europe intellectual property rules of Horizon Europe Regulation, in particular its articles 38 to 41." The grant component of blended finance is now explicitly subject to the same IP obligations as any other Horizon Europe grant.

For companies, this means that the IP autonomy previously granted to blended finance recipients at the grant level has been withdrawn. Companies and co-investors are still given "maximum autonomy regarding intellectual property management" on the investment side, within applicable national legislation, for the purposes of deploying the innovation and enabling an effective exit. But the grant component now carries its own IP obligations, and companies should review what those obligations require before assuming they have unrestricted freedom over their IP strategy.

New Bucket 1 Sub-Case: Societal Need or EU Priority

The 2023 guidelines divided Bucket 1 into cases where the Commission conditions the award on a blocking minority and a catch-all category covering all other cases where companies are not investor-ready. The 2026 version adds a distinct intermediate sub-case: innovations that have "the potential to have a high impact by addressing a societal need or an EU priority."

For companies falling into this new sub-case, the guidelines specify that the Fund may proceed using quasi-equity or a combination of quasi-equity and equity, will include an adequate support package, will pursue a board member seat where it operates as a major investor with ten per cent or more ownership, and will seek external mentoring. This gives the Fund a structured pathway for companies that are strategically important but do not trigger the blocking-minority condition and are not simply generic early-stage cases.

Bucket 3: Listed Companies Removed

The 2023 guidelines described Bucket 3 as covering "cases where potential investors show immediate interest in providing the full investment into EIC candidate companies including the case of listed companies." The 2026 version removes the reference to listed companies entirely. Bucket 3 now covers only cases where potential investors show immediate interest in providing the full investment into EIC Applicant Companies, without mention of public-market status.

Terminology Changes

The 2026 guidelines introduce consistent terminology changes that appear throughout the document:

• "EIC Selected Beneficiary" becomes "EIC Selected Applicant"
• "investee" and "investee companies" become "EIC Fund Final Recipient" used consistently throughout
• "EIC Fund Agreement" becomes "EIC Fund Investment Agreement"
• "grant agreement" is complemented by references to "EIC Accelerator contract"

These are not cosmetic changes. The shift from "beneficiary" to "applicant" for pre-investment companies is a more accurate description of their status during due diligence, since the company is an applicant to the investment process until the External AIFM decides. The consistent use of "EIC Fund Final Recipient" rather than "investee" aligns with the formal legal terminology of the fund documentation.

EU Financial Regulation Article Numbers Updated

The 2023 guidelines referenced Articles 136 to 141 and Article 155(2) of the EU Financial Regulation. The 2026 version references Articles 138 to 143 and Article 158(2). This reflects amendments to Regulation (EU, Euratom) 2018/1046 that renumbered the exclusion criteria and financial provisions. The substantive requirements behind these articles have not changed in a way that alters the investment process, but applicants and their legal advisors should verify references against the current consolidated text of the Financial Regulation.

Definitions Annex Removed

The 2023 guidelines included a comprehensive Annex 1 containing over fifty defined terms, from "Adviser" and "Advisory Committee" through to "Voting Policy" and "VC." This annex provided standalone definitions for concepts such as Qualified Investor, Sanctions, Non-Compliant Jurisdiction, Follow-on Investment, Investment Committee, EIC Selected Beneficiary, and many others. The 2026 version does not include a definitions annex. These definitions are presumably consolidated in the General Section of the EIC Fund Memorandum or in a separate annex not published alongside the investment guidelines.

For practical purposes, the most important definition to track is "Qualified Investor," because it determines who qualifies as a co-investor capable of satisfying the matching requirements. The 2023 version defined a Qualified Investor as "an investor deploying privately sourced funds in an EIC Fund Final Recipient with demonstrable know-how and experience in the relevant market, technology and jurisdiction." Companies and their advisors should confirm whether this definition has been retained, amended, or superseded in the current version of the EIC Fund Memorandum.

Exit Provisions: Symbolic-Price Exit Made Explicit

The 2023 guidelines addressed insolvency but did not explicitly state a general right to exit at a symbolic price outside the context of remedial measures for non-compliance. The 2026 version adds a new clause: "The Compartment will not rule out, if and to the extent possible under the relevant EIC Fund Investment Agreement, in case of a non-performing EIC Fund Final Recipient, an exit via redemption or sale of the Investment to a third party at a symbolic price."

This gives the Fund explicit cover to write off non-performing investments cleanly, without requiring a formal insolvency proceeding or a non-compliance finding. For companies that have failed to achieve their milestones, this clause provides a path for the Fund to exit without prolonging a zombie investment, which also frees the company from the governance obligations that attach to an EIC Fund shareholding.

Structural Changes

The 2023 guidelines opened with four preliminary sections: Investment Rules (including Investment Restrictions, Investment Objective, and Investment Strategy), a detailed Investment Strategy section describing how proposals flow from selection through to legal documentation, and a seven-step Compartment Investment Process. These sections provided context on where the investment guidelines sit within the broader EIC architecture.

The 2026 version removes all of these preamble sections and begins directly with the Investment Guidelines content. The document is shorter as a result, at eighteen pages compared to the longer 2023 version, and reads as a more focused operational rulebook rather than a combined strategic and operational document. The seven-step process, the Investment Objective statement, and the Investment Strategy narrative are either incorporated into other EIC documents or considered established enough to no longer require repetition.

What These Changes Mean for Applicants

Taken together, the 2026 revisions adjust the balance of the fund in four directions. First, larger tickets and broader follow-on conditions make the fund a more substantial capital partner for companies that need significant equity to scale, particularly under the EIC STEP instrument. Second, the broadened "EU interests" framing and the defence-sector opening reflect a policy environment where economic sovereignty and security are more prominent in EIC decision-making than they were in 2023. Third, the removal of the IP exemption tightens the obligations on blended finance recipients at the grant level, which means that companies must now manage their IP strategy across two distinct regulatory frameworks simultaneously. Fourth, the streamlined document structure and removed definitions annex suggest that the investment guidelines are being positioned as one component of a larger documentation set, and companies should ensure they have access to the full EIC Fund Memorandum rather than treating the investment guidelines as a self-contained document.
