Commission File Number: 001-04547

Date: September 11, 2018

On September 11, 2018, Unilever N.V. and Unilever PLC sent the following letter to the Investor Forum:

Dear Simon and Andy,

Thank you for visiting our offices to discuss our Simplification proposal. We were pleased to have the opportunity to talk with the Investor Forum and found our meeting very constructive. As discussed, we’re following up with a note which covers the matters you raised and which we covered at the meeting.

As you know we have engaged extensively with shareholders and have so far discussed Simplification at over 150 meetings since our announcement. We will continue to meet with shareholders on this matter until the EGMs take place towards the end of October.

Rationale for the proposed change

Improved Governance:

For the first time, one share will mean one vote, with all shareholders of the new parent company, “New Unilever NV”, voting on the same basis and as a single class of shareholders with a single set of rights for all. On or prior to Simplification we will cancel the NV preference shares, terminate the depositary receipt structure and close the Trust Office, which can currently exercise the votes of all depositary receipt holders who do not give voting instructions.

Additional shareholder rights will be included, such as a lower overall threshold for proposing resolutions (including the ability to propose the appointment or removal of directors) and there will be a single set of rights for all shareholders instead of the current position of having different thresholds for PLC and NV shareholder votes.  We will not have any defensive mechanisms (such as protective foundations or “stichtingen” as used by some Dutch companies), and no ability to put such devices in place without shareholder approval. These proposals will further strengthen Unilever’s governance. For the first time, the whole of Unilever will be subject to the UK Listing Rules, as New NV will seek a premium listing in London. The Class 1, Class 2 and Related Party Rules will therefore apply, providing further shareholder protections for all shareholders.

Greater Strategic Flexibility:

The proposal will provide Unilever with greater flexibility for strategic portfolio change. Our experience from the Spreads disposal was that a demerger to shareholders of part of our portfolio is extremely difficult from a dual-parent structure. Large-scale equity settled acquisitions would be easier under a single parent structure, with one class of share and one pool of liquidity, and would be more tax efficient for US shareholders. However, we must stress that no such transactions are currently contemplated or under consideration.

Simpler, with a larger single pool of liquidity:

One single parent company will replace our current complex dual parent company structure (which includes cross shareholdings of special shares, interdependent shareholder resolutions from separate voting constituencies, dividend equalization agreements, and mutual guarantees). The single class of shares will be simpler for current and potential shareholders who will no longer have to assess the relative merits of NV shares versus PLC shares before making an investment, and we will have a larger, single, pool of liquidity for all our shares.

Board Process

The Board conducted a review of Unilever’s corporate structure as one of the outcomes of the broader strategic review it carried out in 2017. This review was in-depth and extensive, using external advisers, and considering multiple factors such as legal, tax, regulatory, governance and the

impact on shareholders. The Board of Unilever was very closely involved throughout, offering and encouraging challenge before reaching its conclusion.

The Board announced its intention to unify the company in November and subsequently announced the details of the structure in March this year. Other structures were considered as part of this review. However, the Board did not consider that these other structures achieved Unilever’s objectives of simplifying, creating greater strategic flexibility and providing an opportunity to strengthen corporate governance.

Choice of location

Having made the decision to unify, the Board had to choose a location. While the Board gave consideration to a new location other than the UK and the Netherlands, it concluded that it should retain the historical Anglo-Dutch heritage of Unilever. Both the UK and the Netherlands are world class locations for doing business. In making its decision the Board looked at multiple factors such as tax, governance and legal. The Board also took into account the fact that NV is 22% larger than PLC, with NV shares representing 55% of the total market capitalisation of Unilever today; NV shares also currently trade with greater liquidity and at a premium to the PLC shares. Based on these factors the Board chose to recommend incorporating under a new holding company in the Netherlands. The Board also decided, as part of its review, to headquarter and manage our global Homecare and Beauty and Personal Care divisions in London, having previously announced that the Foods and Refreshment Division would be headquartered in the Netherlands.

Index Inclusion

The Board was aware that by choosing to simplify to a single class of shares, it would be likely that Unilever would no longer be included in both the major Euro indices (such as the major EuroSTOXX 50) and the UK indices (such as FTSE 100). While index providers allow the inclusion of each company in a dual-parent structure in two indices, their rules require that a single-headed company be assigned a single nationality. The Board was therefore conscious that after Simplification, Unilever would almost certainly be excluded from either the various Euro indices or the UK indices. In this regard it is worth noting that RELX was not part of the EuroSTOXX 50, because of its size, and therefore did not forfeit inclusion in that index by deciding to unify in the UK.

The board review recognised that individual investors have different mandates, and that some will have more flexibility than others to continue to hold their Unilever shares after simplification. As a result, following the announcement in March, we engaged extensively with FTSE-Russell and suggested Unilever be grandfathered such that 45% of its market capitalisation could remain within the FTSE UK series — a reflection of our history and continued significant presence in the UK. Although Unilever understands that FTSE Russell, after consultation with its major institutional clients, has not yet made a final decision, we believe it is extremely likely that New Unilever NV will be excluded from the FTSE UK series, but given a full weighting in the FTSE Euro indices. Our weighting in many other indices will increase, such as the EuroSTOXX 50 where we will move from being the 10th to the 3rd largest constituent. In many other indices the weighting will be unchanged as both NV and PLC are current constituents and so we are already weighted on a combined basis.

This does not affect the fact that Unilever will seek a premium listing on the LSE and be quoted, and have dividends paid, in GBP. There will also be the benefit that the transfer of interests in shares in the new holding company should ordinarily no longer be subject to Stamp Duty in the UK.

We believe that the enhanced liquidity from one class of shares listed in full on three exchanges, strengthened corporate governance and the premium of the NV shares will, if there is any impact at all on the cost of capital, be positive for shareholders.

Dutch Dividend Withholding Tax (DWT)

Currently the existence of DWT in the Netherlands means that holders of NV shares are subject to a tax on dividends which is reclaimable in some countries (notably the US) but in some is not. The Dutch government has announced that it plans to pass legislation to abolish DWT from 1 January 2020, something for which a number of companies have been lobbying for many years.

In the intervening period between the implementation of Simplification and the abolition of DWT, New Unilever NV will take steps which will enable it to make alternative ‘dividend substitution payments’ to shareholders of New Unilever NV that qualify as repayments of nominal share capital for DWT purposes. Any such dividend substitution payments received by a New Unilever NV shareholder or ADS holder should be treated as income distributions for UK tax purposes with the same UK tax consequences as a dividend.

If DWT is not abolished on 1 January 2020 as anticipated, then these arrangements will continue to be used by New Unilever NV, to enable shareholders to receive dividend substitution payments free of DWT (depending on their elections) for a considerable period of time. Further detail in relation to DWT and the interim arrangements is included in the public documentation which has been published today.

Summary

The Board review process has been rigorous, taking account of many factors.   We believe that the proposal is in the interests of Unilever and its shareholders as a whole, and that it is right for the long-term future of the company.

Yours …

Marijn Dekkers
