N&B Transaction — Equity Holdings in DuPont Plans Frequently Asked Questions

As previously announced on December 15, 2019, DuPont de Nemours, Inc. (“DuPont”) and International Flavors & Fragrances, Inc. (“IFF”) entered into a definitive agreement for the combination of IFF and DuPont’s Nutrition & Biosciences (“N&B”) business in a Reverse Morris Trust transaction (“N&B Transaction”). Pursuant to the terms of the N&B Transaction, holders of DuPont Common Stock may be entitled to receive a specified number of shares of IFF common stock for each share of DuPont Common Stock they hold. Notional DuPont equity within the DuPont equity incentive and deferred compensation plans (“DuPont Plans”) will not be redenominated in IFF shares but may instead be adjusted so that the value of the notional DuPont Common Stock does not change.

This communication is intended only for active employees who will remain with DuPont as well as all terminated employees who continue to participate in the Dupont Plans. It addresses important questions you may have regarding the N&B Transaction and how it will affect your DuPont equity holdings in DuPont Plans.

Exchange Offer

What is an Exchange Offer and what does it mean for my awards?

As described in the Schedule TO filed with the SEC on December 31, 2020, the N&B Transaction will be completed via a split-off. As a part of the split-off transaction, an exchange offer is being made to stockholders of DuPont de Nemours, Inc., allowing them to exchange shares of DuPont Common Stock for shares of N&B. Shares of N&B will then convert to shares of IFF common stock at the close of the N&B Transaction. If the exchange offer is not fully subscribed, the N&B shares which DuPont continues to hold at the end of the exchange will be distributed on a pro rata basis to all remaining DuPont shareholders.* Shares of N&B will then convert to shares of IFF common stock at the close of the N&B Transaction. All unvested or unexercised awards as well as all investments in DuPont Common Stock in the Deferred Compensation plans are notional and are not eligible to participate in the exchange offer, but will be adjusted to maintain their economic value.

If you hold vested, unexercised stock options or SARs and wish to exercise the awards and participate in the exchange, you must exercise your awards so that they settle on or before the date of the closing of the exchange offer. We expect this means that you should exercise your awards no later than January 20, 2021.

Can I participate in the exchange?

Any employee who holds shares of DuPont Common Stock is able to participate in the exchange and will receive separate communications with details on how to participate. Holders of notional shares, such as notional investments in the US deferred compensation plans or awards under the DuPont Long-Term Incentive plans, are not eligible to participate in the exchange.

If you hold vested, unexercised stock options or SARs and wish to exercise the awards and participate in the exchange, you must exercise your awards so that they settle on or before the date of the closing of the exchange offer. We expect this means that you should exercise your awards no later than January 20, 2021.

Where can I get additional information in regard to the exchange?

In connection with the N&B Transaction, N&B has filed a registration statement on Form S-4/S-1 containing a prospectus, dated December 31, 2020, IFF has filed a registration statement on Form S-4 containing a prospectus, dated December 31, 2020 (together, the “registration statements”), and DuPont has filed a Schedule TO with the SEC. Investors and security holders are urged to read the registration statements, DuPont’s Schedule TO and any amendments or supplements to these filings as well as any other relevant documents filed or to be filed with the SEC when they become available because they will contain important information about N&B, IFF and DuPont and the N&B Transaction. The registration statements, DuPont’s Schedule TO and other documents relating to the N&B Transaction (when they become available) can also be obtained free of charge from the SEC’s website at www.sec.gov.

Long-Term Incentive (“LTI”) Plan

What are outstanding equity awards?

Outstanding equity awards include any unvested restricted stock units (“RSUs”) and dividend equivalent units (“DEUs”), unvested performance share units (“PSUs”), and also include any vested and unexercised or unvested stock options (“Options”) or stock appreciation rights (“SARs”).

Do I need to take any action to adjust my awards?

No. Awards will be adjusted automatically. Prior to the closing of the transaction, you will receive an additional communication which will describe the manner in which outstanding equity awards will be adjusted.

Will I need to accept my awards again after the adjustment?

No. If you have already accepted your awards, you will not need to accept again.

How will the N&B Transaction impact the performance conditions of the PSUs?

PSUs, as well as all other award types, will not have any changes made to the Terms and Conditions of the awards.

Where can I find the terms and conditions of my award(s)?

The terms and conditions for each award you have outstanding can be viewed on Benefits OnLine^® under the Document Library. Please make sure to review the terms and conditions for each grant year for which you may have outstanding equity awards.

I have shares of DuPont Common Stock held at Merrill that were issued upon vesting of RSUs, PSUs, or DEUs, or exercise of Options or SARs. Will these shares be impacted by the N&B Transaction?

Any shares of DuPont Common Stock that are held in your Merrill brokerage account as a result of previous transactions will be treated the same as shares of DuPont Common Stock held by other DuPont stockholders.

Where will I find information regarding my awards following the N&B Transaction?

You will continue to receive information about your awards through Merrill.

Will there be a blackout period?

Yes, there will be a blackout period due to the adjustment to outstanding equity awards. During this period, you will not be able to exercise options or SARs. The blackout period will begin 3 business days prior to the effective date of the N&B Transaction and end approximately 10 business days after the close date. You will be notified when the blackout ends, and you can view your outstanding award details. Please plan any transactions that you would like to execute before the blackout accordingly.

Please note that the blackout period affects your ability to exercise any outstanding DuPont equity awards. Please call Merrill at (877) DD-PLANS (877-337-5267) to perform any transactions before the blackout period.

Will my Corteva and Dow denominated grants be impacted by the blackout period?

No. You will still be able to view your Corteva and Dow denominated grants in the Merrill system. You will also be able to exercise Corteva/Dow Options and SARs, if applicable.

If I have a limit order in place, what happens to it if the price I set is reached during the blackout period? What happens to it at the time of the N&B Transaction?

Limit orders are cancelled during the blackout prior to the adjustment of the awards.

What happens if the exercise price for my stock options is above the market price of DuPont Common Stock at the time of the N&B Transaction?

The conversion methodology used will be the same whether the exercise price is above or below the market price at the time of the N&B Transaction. In other words, if the exercise price is above the market price immediately prior to the N&B Transaction, it will likely remain so immediately following the closing of the N&B Transaction.

What happens if I have an RSU vest during the blackout?

Any vesting event that occurs during the blackout will be processed at the end of the blackout period, utilizing the price in effect as of the actual vesting date.

2

What happens if I have Options that expire during the blackout?

If your Options are due to expire during the blackout and you wish to exercise these awards, you must exercise prior to the blackout period.

What are the tax implications of the N&B Transaction on my equity awards?

Neither DuPont nor Merrill provides tax advice. We urge you to consult your personal tax advisor to determine the specific tax consequences to you.

What further action do I need to take?

You do not need to take any action regarding your awards at this time. Awards will be adjusted automatically following the N&B Transaction. Communications will be sent following the N&B Transaction to alert you that your awards have been adjusted.

If you have questions about your current outstanding equity awards, contact Merrill at (877) 337-5267 from the U.S., Puerto Rico or Canada. From other locations enter the local AT&T Direct access number for your country, and then call (877) 785-6786. Participant Service Representatives are available virtually 24 hours a day, 7 days a week.

Deferred Compensation Plans (US only)

What equity holdings may I have in the deferred compensation plans?

A notional investment in DuPont shares is available as an investment option under the DuPont Retirement Savings Restoration Plan (“RSRP”), DuPont Management Deferred Compensation Plan (“MDCP”), and DuPont Variable Compensation Plan. Under the RSRP and MDCP, you can change your investment mix at any time. You will see this investment noted as “DUPONT DE NEMOURS INC” in your Merrill account.

What are notional investments?

Deferred compensation plans are unfunded, and as such no actual dollars are invested based on the investment election you designate. Instead, your deferrals are tracked as if the dollars had been invested per your direction and then at the time of distribution the company pays the full cash value or provides the shares to you.

Do I need to take any action to adjust the notional shares?

No. The number of notional shares will automatically be adjusted at the time of the N&B Transaction. Prior to the closing of the transaction, you will receive an additional communication which will describe the manner in which notional shares will be adjusted.

Will this adjustment impact my payment election or investment direction?

Your payment election and investment direction will not change as a result of the N&B Transaction. You can change your investment direction, if available under your plan, at any time at the Merrill website.

Where will I find information regarding my awards following the N&B Transaction?

You will continue to receive information about your awards through Merrill.

Will there be a blackout period?

Yes, there will be a blackout period due to this adjustment. The blackout period will begin the day prior to the effective date of the N&B Transaction and will end three business days after the close of the N&B Transaction. During the blackout, you will not be able to complete any transactions, such as changing your investment direction.

What further action do I need to take?

You do not need to take any action at this time. Notional investments will be adjusted automatically following the N&B Transaction. Communications will be sent following the N&B Transaction to alert you that your adjustment is complete.
