PMV PHARMACEUTICALS, INC.

OFFER TO EXCHANGE

CERTAIN OUTSTANDING STOCK OPTIONS

FOR NEW STOCK OPTIONS

This document constitutes part of the prospectus relating to the securities that have been registered under the Securities Act

of 1933, as amended.

The prospectus relates to the PMV Pharmaceuticals, Inc. 2020 Equity Incentive Plan.

July 16, 2024

PMV PHARMACEUTICALS, INC.

OFFER TO EXCHANGE CERTAIN

OUTSTANDING STOCK OPTIONS FOR NEW STOCK OPTIONS

This Offer and withdrawal rights will expire at 11:59 p.m., Eastern Time, on August 13, 2024, unless we extend them.

By this offer (the “Offer”), PMV Pharmaceuticals, Inc. (“PMV,” “we,” “our” or “us”) is giving eligible employees of PMV the opportunity to exchange some or all of their stock options granted under our 2020 Equity Incentive Plan (the “2020 Plan”) following the closing of the Company’s initial public offering on September 29, 2020, with a per share exercise price greater than $4.36, whether vested or unvested, that are outstanding at the start of this Offer and remain outstanding and unexercised through the expiration of this Offer (“eligible options”), for new options to purchase shares of our common stock (“new options”). New options will be granted under, and subject to, the terms and conditions of the 2020 Plan and stock option agreement thereunder. All employees of PMV (including our executive officers) who hold eligible options and remain employed through the date of grant for new options may participate in this Offer (“eligible employees”). Consultants and non-employee members of our board of directors will not be eligible to participate.

The Offer will expire at 11:59 p.m., Eastern Time, on August 13, 2024, unless we extend the date (such date of expiration, the “expiration date”). Eligible employees may tender eligible options on or before the expiration date in order to receive new options. New options will cover the same number of shares of our common stock as the number of shares subject to the exchanged options. All new options will have an exercise price per share equal to the closing sales price of a share of our common stock on the Nasdaq Global Select Market on the expiration date (the “new option grant date”). We expect the new option grant date to be August 13, 2024. If the expiration date of the Offer is extended, then the new option grant date will be similarly extended.

For U.S. federal income tax purposes, all new options will retain the same tax status as the corresponding eligible option cancelled in the Offer to the maximum extent permitted by law. In other words, incentive stock options will be exchanged for incentive stock options, and nonstatutory stock options will be exchanged for nonstatutory stock options, subject to applicable law. The new options will be unvested as of the new option grant date, regardless of the extent to which the exchanged eligible options were vested, and will be scheduled to vest based on continued service with us through each applicable vesting date in accordance with the new vesting schedule. The new vesting schedule provides that:

In all events, vesting is subject to continued service with us through the applicable vesting date. Your participation in this Offer and receipt of any new options does not provide any guarantee or promise of continued service with us. The maximum term of the new option grant will be 10 years from the new option grant date.

Our common stock is traded on the Nasdaq Global Select Market under the symbol “PMVP.” On July 15, 2024, the closing sales price of our common stock was $1.63 per share on the Nasdaq Global Select Market. You should evaluate current market quotes for our common stock, among other factors, before deciding to participate in this Offer.

See “Risks of Participating in the Offer” beginning on page 13 for a discussion of risks that you should consider before participating in this Offer.

“2020 Plan” refers to our 2020 Equity Incentive Plan.

“cancellation date” refers to the calendar date when exchanged options will be cancelled. Exchanged options will be cancelled on the same calendar day as the expiration date and the new option grant date.

If the expiration date is extended, then the cancellation date similarly will be extended.

“eligible option grant” refers collectively to all of the eligible options that are part of the same option grant and subject to the same stock option agreement. For example, if an individual has been granted eligible options to purchase a total of 1,000 shares of our common stock under the 2020 Plan subject to a stock option agreement under the 2020 Plan, the eligible option grant refers to the entire award of eligible options to purchase 1,000 shares of our common stock. If the individual has exercised 600 shares subject to that award, eligible option grant refers to the award of eligible options to purchase 400 shares of our common stock that remain subject to the award.

“eligible options” refers to stock options to purchase shares of our common stock that (i) have a per share exercise price greater than $4.36, (ii) were granted after September 29, 2020 (the date of our initial public offering) under the 2020 Plan, and (iii) are outstanding and unexercised as of the expiration date.

“Nasdaq” refers to the Nasdaq Global Select Market.

“new option grant date” refers to the date when new options will be granted. The new option grant date will be the same calendar day as the expiration date.

“new option grant” refers collectively to all new options that are part of the same grant and subject to the same stock option agreement.

“new options” refers to the options to purchase shares of our common stock granted pursuant to this Offer that replace the exchanged options.

Questions and answers

2

Further, not only do significantly underwater options have little or no retention value, but they also cannot be removed from our pool of equity awards granted until they are exercised, expire or otherwise terminate (for example, when an employee leaves our employment). If we do not conduct this Offer in which underwater stock options with low incentive value may be exchanged for stock options with higher motivation and retentive value, we may find it necessary to issue significant additional stock options or other equity awards to employees above and beyond our ongoing equity grant practices in order to provide renewed incentive value to our employees. (See Section 3 of “The Offer” below.)

To help you recall your eligible option grants and give you the information that may be useful for making an informed decision, please refer to the personalized information regarding each eligible option grant that you hold which is available via the Offer website that lists: the grant date of the eligible option grant; the per share exercise price of the eligible option grant; whether the eligible option grant is an incentive stock option or nonstatutory stock option; the number of vested and unvested shares of our common stock subject to the eligible option grant as of August 13, 2024 (assuming vesting in accordance with the applicable vesting schedule, and no exercise or early termination occurs, through such date); the number of shares of our common stock subject to the new option grant that would be granted in exchange for the eligible option grant; and the vesting schedule of the new option grant. If you are unable to access your personalized information regarding each eligible option grant that you hold, you may contact Asia Higgins, our Assistant Controller, or Keri Smith, our Senior Manager, Accounting, by email at optionexchange@pmvpharma.com or by phone at (609) 642-6670. (See Section 2 of “The Offer” below.)

3

Moreover, even if we accept your exchanged options, we will not grant new options to you if we are prohibited from doing so by applicable laws. For example, we could become prohibited from granting new options as a result of changes in SEC or Nasdaq rules. However, we do not anticipate any such prohibitions at this time. (See Section 13 of “The Offer” below.)

In addition, if you hold an option that expires after the start of the Offer but on or before the cancellation date, that particular option is not eligible for exchange. As a result, if you hold options that expire on or before the currently scheduled cancellation date or, if we extend the Offer such that the cancellation date is a later date and you hold options that expire on or before the rescheduled cancellation date, those options will not be eligible for exchange and such options will continue to be governed by their original terms. (See Section 16 of “The Offer” below.)

For purposes of your eligibility to participate in this Offer, your employment with PMV will not be considered to have terminated while you are on a leave of absence that has been approved by PMV.

Elections via the Offer website

4

We must receive your properly completed and submitted election by the expiration of the Offer, currently expected to be 11:59 p.m., Eastern Time, on August 13, 2024. If you are unable to submit your election via the Offer website as a result of technical failures of the Offer website such as the Offer website being unavailable or the Offer website not enabling you to submit your election, please contact Asia Higgins, our Assistant Controller, or Keri Smith, our Senior Manager, Accounting, by email at optionexchange@pmvpharma.com or by phone at (609) 642-6670.

If you elect to exchange any eligible option grant in this Offer, you must elect to exchange all eligible options subject to that eligible option grant. If you hold more than one eligible option grant, however, you may choose to exchange one or more of such eligible option grants without having to exchange all of your eligible option grants.

We may extend this Offer. If we extend the offering period, we will issue a press release, email or other communication disclosing the extension no later than 9:00 a.m., Eastern Time, on the U.S. business day following the previously scheduled expiration date.

This is a one-time offer, and we will strictly enforce the offering period. We reserve the right to reject any option tendered for exchange that we determine is not in the appropriate form or that we determine is unlawful to accept. Subject to the terms and conditions of this Offer, we will accept all properly tendered eligible option grants promptly after the expiration of this Offer.

Your delivery of all documents regarding the Offer, including elections, is at your risk. If you submit your election via the Offer website, a confirmation statement will be generated by the Offer website at the time that you complete and submit your election. You should print and keep a copy of the confirmation statement for your records. A copy of the confirmation statement will also be sent to your email. The printed confirmation statement will provide evidence that you submitted your election. If you do not receive a confirmation, it is your responsibility to confirm that we have received your election. If you do not receive a confirmation, we recommend that you confirm that we have received your election by contacting Asia Higgins, our Assistant Controller, or Keri Smith, our Senior Manager, Accounting, by email at optionexchange@pmvpharma.com or by phone at (609) 642-6670. Only responses that are properly completed and actually received by us by the deadline by the Offer website at www.myoptionexchange.com will be accepted. Responses submitted by any other means, including hand delivery, interoffice, email, U.S. mail (or other post) and Federal Express (or similar delivery service), are not permitted. (See Section 4 of “The Offer” below.)

5

Example. For illustrative purposes only, assume that you are an eligible employee, and that you hold an eligible option grant covering 3,000 shares of our common stock with a per share exercise price of $16.00. If you exchange this eligible option grant under the Offer, then on the new option grant date, you will receive a new option grant covering 3,000 shares of our common stock.

In all cases described above, vesting is subject to your continued service to us through each vesting date. Your participation in this Offer and the receipt of new options does not provide any guarantee or promise of continued service with us. The maximum term of the new option grant will be 10 years from the new option grant date. (See Section 9 of “The Offer” below.)

6

Example 1

For illustrative purposes only, assume that you are an eligible employee and that you exchange in the Offer an eligible option grant to purchase 3,600 shares of our common stock that was granted before April 30, 2022. There are no specific accelerated vesting terms that apply to your eligible option grant. Assume also that the Offer expires and new options are granted on August 13, 2024. Under the terms of the Offer, the new option grant will cover 3,600 shares, be entirely unvested upon the new option grant date, and have a vesting commencement date of August 13, 2024. The maximum term of the new option grant will be 10 years from August 13, 2024.

The new option grant will be scheduled to vest as to 1,200 shares on August 13, 2025, the 1-year anniversary of the new option grant date, and thereafter will vest as to 100 shares on each monthly anniversary of the new option grant date, subject to your continued service to us through each vesting date.

Example 2

For illustrative purposes only, assume that you are an eligible employee and that you exchange in the Offer an eligible option grant to purchase 4,800 shares of our common stock that was granted after April 30, 2022. There are no specific accelerated vesting terms that apply to your eligible option grant. Assume also that the Offer expires and new options are granted on August 13, 2024. Under the terms of the Offer, the new option grant will cover 4,800 shares, be entirely unvested upon the new option grant date and have a vesting commencement date of August 13, 2024. The maximum term of the new option grant will be 10 years from August 13, 2024.

The new option grant will be scheduled to vest as to 1,200 shares on August 13, 2025, the 1-year anniversary of the new option grant date, and thereafter will vest as to 100 shares on each monthly anniversary of the new option grant date, subject to your continued service to us through each vesting date.

For example, and except as otherwise described below, if you hold (i) an eligible option grant to purchase 1,000 shares of our common stock, 700 of which you have already exercised, (ii) an eligible option grant to purchase 1,000 shares of our common stock and (iii) an eligible option grant to purchase 2,000 shares of our common stock, you may elect to exchange:

7

These are your only choices in the above example. You may not elect, for example, to exchange your first eligible option grant with respect to only 150 shares of our common stock (or any other partial amount) under that eligible option grant or less than all of the shares of our common stock under the second or third eligible option grants. (See Section 2 of “The Offer” below.)

For example, if you are an eligible employee and you hold an eligible option grant covering 3,000 shares of our common stock that is subject to a domestic relations order, one-third (1/3) of which is beneficially owned by your former spouse (that is, the portion covering 1,000 shares of our common stock), and you have exercised 600 of the remaining 2,000 shares of our common stock subject to the eligible option grant not beneficially owned by your former spouse, then you may elect to exchange the outstanding portion of your eligible option grant covering 2,400 shares of our common stock, including the portion covering the 1,000 shares of our common stock beneficially owned by your former spouse, or you may elect not to participate in the Offer at all with respect to this eligible option grant. These are your only choices with respect to this eligible option grant. (See Section 2 of “The Offer” below.)

8

Your new options will have a different exercise price (as discussed in Q&A 12), vesting schedule (as discussed in Q&A 13), and maximum term (as discussed in Q&A 13). In addition, as discussed in Q&A 25, for U.S. federal income tax purposes, all new options will retain the same tax status as the corresponding eligible option cancelled in the Offer to the maximum extent permitted by law. (See Section 9 of “The Offer” below.)

The vesting of new options will differ significantly from the corresponding exchanged options. Among other differences, no new options will be scheduled to vest before the one-year anniversary of the new option grant date, even if the corresponding exchanged options are partially or fully vested (as discussed in Q&A 13).

9

If you are subject to the tax laws of a country other than the United States, even if you are a resident of the United States, you should be aware that there may be other tax consequences that may apply to you. Tax consequences may vary depending on each individual’s circumstances. Included as part of this option exchange are disclosures regarding the expected material federal tax consequences of this Offer in the United States and in countries other than the United States in which employees of PMV Pharma are eligible to participate in the Offer. You should review these disclosures carefully before deciding whether or not to participate in this Offer. (See Schedule C of the Offer to Exchange entitled “A Guide to Tax & Legal Issues for Non-U.S. Employees” below for additional information.)

For all employees, we recommend that you consult with your own tax adviser to determine the personal tax consequences to you of participating in this Offer.

We recommend that you read the tax discussion in Section 14 of “The Offer” below and discuss the personal tax consequences of incentive stock options and nonstatutory stock options with your financial, legal and/or tax advisers. (See Section 9 and Section 14 of “The Offer” below.)

RISKS OF PARTICIPATING IN THE OFFER

Participating in the Offer involves a number of risks, including those described below. The risks described below, as well as the risk factors in our Quarterly Report on Form 10-Q for the fiscal quarter ended March 31, 2024, filed with the SEC on May 9, 2024, and our Annual Report on Form 10-K fiscal year ended December 31, 2023, filed with the SEC on February 29, 2024, highlight some of the material risks related to PMV and which may impact your decision whether to participate in this Offer. You should consider these risks carefully, and you are encouraged to speak with an investment and tax adviser as necessary before deciding whether to participate in the Offer. In addition, we urge you to read the sections in this Offer to Exchange discussing the tax consequences of participating in the exchange of options pursuant to the Offer, as well as the rest of this Offer to Exchange document, for a more in-depth discussion of the risks that may apply to you before deciding to participate in the Offer.

In addition, this Offer and our SEC reports referred to above include “forward-looking statements.” These statements involve known and unknown risks, uncertainties, assumptions, and other factors that may cause our actual results, performance, or achievements to be materially different from any future results, performance, or achievements expressed or implied by the forward-looking statements. Forward-looking statements include statements that are not historical facts and can be identified by terms such as “anticipates,” “believes,” “could,” “seeks,” “estimates,” “expects,” “intends,” “may,” “plans,” “potential,” “predicts,” “projects,” “should,” “will,” “would,” or similar expressions and the negatives of those terms. These statements are based on our management’s beliefs and assumptions and on information currently available to our management. The documents we file with the SEC, including the reports referred to above, discuss some of the risks that could cause our actual results to differ from those contained or implied in the forward-looking statements. Factors that could cause or contribute to such differences include, but are not limited to, those identified below and those discussed in the section titled “Risk factors” included in our Quarterly Report on Form 10-Q for the fiscal quarter ended March 31, 2024, filed with the SEC on May 9, 2024, and our Annual Report on Form 10-K for the year ended December 31, 2023, filed with the SEC on February 29, 2024. Furthermore, such forward-looking statements speak only as of the date hereof. Except as required by law, we undertake no obligation to update any forward-looking statements to reflect events or circumstances after the date of such statements.

Risks related to Participating in the Offer

New options granted to you in the Offer to Exchange will be entirely unvested as of the new option grant date and will vest over a prescribed time period. You may not exercise these options until they vest, and such vesting requires that you remain in the service of PMV. If your service with us terminates for any or no reason, your unvested new options will expire automatically.

New options granted to you will be unvested as of the new option grant date and subject to a new vesting schedule. This is true even if your exchanged options are already 100% vested. Vesting requires the passage of time and that your services to us continue through each vesting date. If you do not remain an employee or other service provider with us through each date your new options vest, you will not have the right to purchase all of the shares subject to those new options. Instead, the unvested portion of your new options generally will expire immediately upon your termination. As a result, you may not receive any value from your new options. Nothing in the Offer should be construed to confer upon you the right to remain an employee of PMV. The terms of your employment with us remain unchanged. We cannot guarantee or provide you with any assurance that you will not be subject to involuntary termination or that you will otherwise remain employed until the new option grant date or thereafter.

Furthermore, although we currently are not anticipating a merger or acquisition, a transaction involving us, such as a merger or other acquisition, could result in a reduction in our workforce. If your employment or other service with us terminates before part or all of your new options vest, you may not receive any value from the unvested portion of the new options.

The new options granted to you in the Offer to Exchange could become underwater after they are granted.

The new options will have an exercise price per share equal to the closing sales price of a share of our common stock as reported on the Nasdaq Global Select Market on the new option grant date. If the trading price of our common stock decreases after the new option grant date, the exercise price of your new options will be greater than the trading price of our common stock, and you will not be able to realize any gain from the exercise of your new options. The trading price of our common stock has been volatile, and there can be no assurances regarding the future price of our common stock or that the trading price of our common stock will increase after the new option grant date.

13

Tax-related risks

If your new options are granted as incentive stock options in this Offer, you will be required to restart the measurement periods required to be eligible for favorable tax treatment for any new incentive stock options.

In order to receive favorable tax treatment for incentive stock options, the shares subject to the new option are required to be held more than two years after the new option grant date and more than one year after you exercise the new option. The new options will be deemed a completely new grant for purposes of the incentive stock option rules. Accordingly, you will not receive any credit for the time during which you held your exchanged options. In order for the new incentive stock options to be eligible for favorable U.S. federal tax treatment, you would be required to wait to sell any shares of our common stock you receive upon exercise of your new incentive stock option until the passage of more than two years from the new option grant date and more than one year after you exercise the new option. If these holding periods (and all other incentive stock option requirements) are met, the excess of the sale price of the new option shares over the exercise price of the new option will be treated as long-term capital gain. For more detailed information, please read the rest of the Offer to Exchange, and see the tax disclosure set forth under Section 14 entitled “Material U.S. federal income tax consequences.”

Note that some of your exchanged options that are incentive stock options may be exchanged for new options that are nonstatutory stock options. For more detailed information, please read the rest of the Offer to Exchange, and see the tax disclosure set forth under Section 14 of the Offer to Exchange.

The Offer currently is expected to remain open for less than 30 calendar days. If this Offer is extended, you will be required to restart the measurement periods required to be eligible for favorable tax treatment for your existing eligible options that are incentive stock options even if you do not exchange them in the Offer.

Generally, your incentive stock option qualifies for favorable tax treatment if you hold the option for more than two years after the grant date and for more than one year after the date of exercise. Under the tax rules governing incentive stock options, if an offer to modify an incentive stock option remains outstanding for 30 or more calendar days, then the incentive stock option is deemed modified regardless of whether you participate in the offer. The Offer currently is expected to remain open for less than 30 calendar days. However, if the Offer is extended, any eligible options that are incentive stock options that you do not exchange will nonetheless be deemed modified, and the holding period for such options will restart. As a result, in order to qualify for favorable tax treatment, you would be required not to sell or otherwise dispose of any shares of our common stock received upon exercise of those options until more than two years from the date this Offer commenced on July 16, 2024, and more than one year after the date you exercise those options. For more detailed information, please read the rest of the Offer to Exchange, and see the tax disclosure set forth under Section 14 entitled “Material U.S. federal income tax consequences.”

If you are subject to the tax laws of a country other than the United States, even if you are a resident of the United States, you should be aware that there may be other tax consequences that may apply to you. Tax consequences may vary depending on each individual’s circumstances. Included as part of this option exchange are disclosures regarding the expected material federal tax consequences of this Offer in the United States and in countries other than the United States in which employees of PMV Pharma are eligible to participate in the Offer. You should review these disclosures carefully before deciding whether or not to participate in this Offer. (See Schedule C of the Offer to Exchange entitled “A Guide to Tax & Legal Issues for Non-U.S. Employees” below for additional information.)

If you are subject to foreign tax laws, even if you are a resident of the United States, there may be tax and social insurance consequences relating to this Offer.

If you are subject to the tax laws of another country, even if you are a resident of the United States, you should be aware that there may be other tax and social insurance consequences that may apply to you. You should read Schedule C attached to this option exchange. Schedule C discusses the tax consequences relating to the Offer for your country of residence. You should also be certain to consult your own tax advisors to discuss these consequences.

Tax-related risks for tax residents of multiple countries.

If you are subject to the tax laws in more than one jurisdiction, you should be aware that there may be tax and social insurance consequences of more than one country that may apply to you. You should be certain to consult your own tax advisor to discuss these tax consequences.

Risks related to our business and common stock

You should carefully review the risk factors contained in our Quarterly Report on Form 10-Q for the fiscal quarter ended March 31, 2024, filed with the SEC on May 9, 2024, and our Annual Report on Form 10-K for the year ended December 31, 2023, and also the other information provided in this Offer to Exchange and the other materials that we have filed with the SEC, before making a decision on whether or not to tender your eligible options. You may access these filings electronically at the SEC’s website at http://www.sec.gov. In addition, we will provide without charge to you, upon your request, a copy of any or all of the documents to which we have referred you. Please see Section 17 of this Offer to Exchange titled, “Additional information,” for instructions on how you can obtain copies of our SEC filings.

THE OFFER

You are an “eligible employee” if you are an employee of PMV as of the date that the Offer commences, who holds an eligible option and remains an employee of PMV through the new option grant date. Consultants and non-employee members of our board of directors will not be eligible employees. Our executive officers and directors are listed on Schedule A of this Offer to Exchange.

To receive a new option, you must remain employed by us or a successor entity through the new option grant date. For purposes of your eligibility to participate in this Offer, your employment with PMV will not be considered to have terminated while you are on a leave of absence that has been approved by PMV. If you do not satisfy all of the requirements of an eligible employee, you will keep your current eligible options, and they will be treated in accordance with their existing terms and conditions. If we do not extend the Offer, the new option grant date is expected to be August 13, 2024. Except as provided by any applicable law, your employment with us will remain “at-will” and can be terminated by you or PMV at any time, with or without cause or notice. In order to continue to vest in your new options, you must remain an employee or other service provider with us through each relevant vesting date.

Subject to the terms and conditions of this Offer, we will accept for exchange eligible options to purchase shares of our common stock, with a per share exercise price greater than $4.36, granted by the Company’s board of directors after September 29, 2020 (the closing date of our initial public offering) under the 2020 Plan, that are outstanding as of the expiration of the Offer, held by eligible employees, and properly elected to be exchanged (and have not been validly withdrawn) on or before the expiration date. In order to be eligible, options must be outstanding and unexercised as of the expiration date. For example, if a particular option expires after the beginning of the offering period, but before the expiration date, that particular option grant is not eligible for exchange.

Participation in this Offer is completely voluntary. You may pick and choose which of your eligible option grants you wish to exchange. If you hold more than one eligible option grant, you may choose to exchange one or more of such eligible option grants without having to exchange all of your eligible options. However, if you elect to participate in this Offer, you must exchange the entire outstanding and unexercised portion of any particular eligible option grant that you choose to exchange, including any eligible options which are legally, but not beneficially, owned by you. You may not elect to exchange only a portion of any particular eligible option grant (such as the vested portion, or unvested portion, or otherwise). Instead, if you participate in the Offer, you must accept the Offer with respect to all of the shares or our common stock subject to each particular eligible option grant. We are not accepting partial tenders of any option grants. However, you may elect to exchange the remaining portion of any eligible option grant that you have already partially exercised.

For example, and except as otherwise described below, if you hold (i) an eligible option grant to purchase 1,000 shares of our common stock, 700 of which you have already exercised, (ii) an eligible option grant to purchase 1,000 shares of our common stock and (iii) an eligible option grant to purchase 2,000 shares of our common stock, you may elect to exchange:

These are your only choices in the above example. You may not elect, for example, to exchange your first eligible option grant with respect to only 150 shares of our common stock (or any other partial amount) under that eligible option grant or less than all of the shares of our common stock under the second or third eligible option grants.

If you have an eligible option grant that is subject to a domestic relations order (or comparable legal document as the result of the end of a marriage) and a person who is not an eligible employee beneficially owns a portion of that eligible option grant, then in order to participate in the Offer with respect to such eligible option grant, you must accept this Offer with respect to the entire remaining outstanding portion of the eligible option grant, including the portion beneficially owned by the other

15

person. As described in the prior paragraph, we are not accepting partial tenders of an eligible option grant, so you may not accept this Offer with respect to a portion of an eligible option grant that is beneficially owned by you while rejecting it with respect to the portion beneficially owned by someone else. As you are the legal owner of the eligible option, PMV will respect an election properly made by you, but will not be responsible to you or the beneficial owner of the eligible option grant for any errors made by you with respect to such eligible option grant.

For example, if you are an eligible employee and you hold an eligible option grant covering 3,000 shares of our common stock that is subject to a domestic relations order, one-third (1/3) of which is beneficially owned by your former spouse (that is, the portion covering 1,000 shares of our common stock), and you have exercised 600 of the remaining 2,000 shares of our common stock subject to the eligible option grant not beneficially owned by your former spouse, then you may elect to exchange the outstanding portion of your eligible option grant covering 2,400 shares of our common stock, including the portion covering the 1,000 shares of our common stock beneficially owned by your former spouse, or you may elect not to participate in the Offer at all with respect to this eligible option grant. These are your only choices with respect to this eligible option grant.

New options

Subject to the terms of this Offer and upon our acceptance of your properly tendered options, each exchanged option to purchase one share of our common stock will be cancelled and you will be granted a new option to purchase one share of our common stock.

Example. For illustrative purposes only, assume that you are an eligible employee, and that you hold an eligible option grant covering 3,000 shares of our common stock with a per share exercise price of $16.00. If you exchange this eligible option grant under the Offer, then on the new option grant date, you will receive a new option grant covering 3,000 shares of our common stock.

Any new options granted to you will be subject to the terms and conditions of our 2020 Plan and a new stock option agreement to be entered into between you and PMV. The 2020 Plan and form of new stock option agreement under the 2020 Plan are incorporated by reference as exhibits to the Schedule TO with which this Offer to Exchange has been filed and are available on the SEC website at www.sec.gov.

The expiration date for this Offer will be 11:59 p.m., Eastern Time, on August 13, 2024, unless we extend the Offer. We may, in our discretion, extend the Offer, in which event “expiration date” will refer to the latest time and date at which the extended Offer expires. See Section 15 of this Offer to Exchange for a description of our rights to extend, terminate, and amend the Offer.

We believe that this Offer will foster retention of our valuable employees and better align the interests of our employees with those of our stockholders to maximize stockholder value. We issued the currently outstanding options to attract and retain the best available personnel and to provide additional incentives to our personnel. Many of our outstanding options, whether or not they currently are exercisable, have per share exercise prices that are significantly higher than the current market price for a share of our common stock. These options are commonly referred to as being “underwater.” We believe that granting new options in exchange for eligible options will aid in motivating and retaining the eligible employees participating in the Offer because each new option would have a per share exercise price that reflects a more current price with respect to a share of our common stock. We believe that by restarting the vesting on the new options we would grant in the Offer, we provide for a reasonable and a balanced exchange for underwater options and that the extension of vesting would have a much stronger current impact on retention than do underwater options.

Further, not only do significantly underwater options have little or no retention value, but they also cannot be removed from our pool of equity awards granted until they are exercised, expire or otherwise terminate (for example, when an employee leaves our employment). If we do not conduct this Offer in which underwater stock options with low incentive value may be exchanged for stock options with higher motivation and retentive value, we may find it necessary to issue significant additional stock options or other equity awards to employees above and beyond our ongoing equity grant practices in order to provide renewed incentive value to our employees. We believe structuring the program in this manner is in the best interests of our employees and stockholders, because it can provide incentive to our employees with appropriate stock options, maintain the outstanding stock option overhang, and conserve options for future grants.

16

In deciding whether to tender one or more eligible options pursuant to the Offer, you should know that we continually evaluate and explore strategic opportunities as they arise. At any given time, we may be engaged in discussions or negotiations with respect to one or more corporate transactions of the type described below. We also grant equity awards in the ordinary course of business to our directors and our current and new employees, including our executive officers. Our directors and employees, including our executive officers, from time to time may acquire or dispose of our securities. In addition, we may pursue opportunities to raise additional capital through the issuance of equity or convertible debt securities. If this occurs, the percentage ownership of our stockholders could be significantly diluted, and these newly issued securities may have rights, preferences or privileges senior to those of existing stockholders. We cannot assure you that additional financing will be available on terms favorable to PMV, or at all.

Subject to the foregoing and except as otherwise disclosed in this Offer or in our SEC filings, we presently have no plans, proposals or active negotiations that relate to or would result in:

Neither we nor our board of directors nor executive officers makes any recommendation as to whether you should accept this Offer, nor have we authorized any person to make any such recommendation. You should evaluate carefully all of the information in this Offer and consult your own investment and tax advisers. You must make your own decision about whether to participate in this Offer.

Proper election to exchange options

Participation in this Offer is voluntary. If you are an eligible employee, at the start of the Offer you will have received a launch email from David H. Mack, Ph.D., our President and Chief Executive Officer, dated July 16, 2024, announcing this Offer. If you want to participate in the Offer, you must complete the election process via the following method outlined below on or before the expiration of the Offer, currently expected to be 11:59 p.m., U.S. Eastern Time, on August 13, 2024. If you do not want to participate, then no action is necessary.

Elections via the Offer website

17

We must receive your properly completed and submitted election by the expiration of the Offer, currently expected to be 11:59 p.m., Eastern Time, on August 13, 2024. If you are unable to submit your election via the Offer website as a result of technical failures of the Offer website such as the Offer website being unavailable or the Offer website not enabling you to submit your election, please contact Asia Higgins, our Assistant Controller, or Keri Smith, our Senior Manager, Accounting, by email at optionexchange@pmvpharma.com or by phone at (609) 642-6670.

If you elect to exchange any eligible option grant in this Offer, you must elect to exchange all eligible options subject to that eligible option grant. If you hold more than one eligible option grant, however, you may choose to exchange one or more of such eligible option grants without having to exchange all of your eligible option grants.

We may extend this Offer. If we extend the offering period, we will issue a press release, email or other communication disclosing the extension no later than 9:00 a.m., Eastern Time, on the U.S. business day following the previously scheduled expiration date. Your election to participate becomes irrevocable after 11:59 p.m., Eastern Time, on August 13, 2024, unless the offering period is extended past that time, in which case your election will become irrevocable after the new expiration date. Due to certain requirements under U.S. securities laws, an exception to this rule is that if we have not accepted your properly tendered options by 11:59 p.m., Eastern Time, on September 11, 2024 (which is the 40th U.S. business day following the commencement of the Offer), you may withdraw your options at any time thereafter but prior to our acceptance.

You may change your mind after you have submitted an election and withdraw from the Offer at any time on or before the expiration date, as described in Section 5 below. You may change your mind as many times as you wish, but you will be bound by the properly submitted election we receive last on or before the expiration date. You also may change your mind about which of your eligible option grants you wish to have exchanged. If you wish to include more or fewer eligible option grants in your election, you must complete and submit a new election on or before the expiration date by following the procedures described in Section 5 below. This new election must be properly submitted after any prior elections you have submitted and must list all eligible option grants you wish to exchange. Any prior election will be disregarded. If you wish to withdraw some or all of the eligible option grants you elected for exchange, you may do so at any time on or before the expiration date by following the procedures described in Section 5 below.

Your delivery of all documents regarding the Offer, including elections, is at your risk. If you submit your election via the Offer website, a confirmation statement will be generated by the Offer website at the time that you complete and submit your election. You should print and keep a copy of the confirmation statement for your records. A copy of the confirmation statement will also be sent to your email. The printed confirmation statement will provide evidence that you submitted your election. If you do not receive a confirmation, it is your responsibility to confirm that we have received your election. If you do not receive a confirmation, we recommend that you confirm that we have received your election by contacting Asia Higgins, our Assistant Controller, or Keri Smith, our Senior Manager, Accounting, by email at optionexchange@pmvpharma.com or by phone at (609) 642-6670.

Responses submitted by any other means, including hand delivery, interoffice, email, U.S. mail (or other post) and Federal Express (or similar delivery service), are not permitted.

This is a one-time offer, and we will strictly enforce the offering period. We reserve the right to reject any option tendered for exchange that we determine is not in the appropriate form or that we determine it is unlawful to accept. Subject to the terms and conditions of this Offer, we will accept all properly tendered eligible option grants promptly after the expiration of this Offer.

Our receipt of your election is not by itself an acceptance of your options for exchange. For purposes of this Offer, we will be deemed to have accepted options for exchange that are validly elected to be exchanged and are not properly withdrawn as of the time when we give oral or written notice to the option holders generally of our acceptance of options for exchange. We may issue this notice of acceptance by press release, email or other form of communication. Options accepted for exchange will be cancelled on the cancellation date, which we presently expect will be August 13, 2024.

Determination of validity; rejection of options; waiver of defects; no obligation to give notice of defects

We will determine, in our discretion, all questions about the validity, form, eligibility (including time of receipt) and acceptance of any eligible options. Our determination of these matters will be given the maximum deference permitted by law. However, you have all rights accorded to you under applicable law to challenge such determination in a court of competent jurisdiction. Only a court of competent jurisdiction can make a determination that will be final and binding upon the parties. We reserve the right to reject any election of any option tendered for exchange that we determine is not in an appropriate form or that we determine is unlawful to accept. We will accept all properly tendered eligible options that are not validly withdrawn, subject to the terms of this Offer. We also reserve the right to waive any of the conditions of the Offer or any defect or irregularity in any tender of any particular options or for any particular option holder, provided that if we grant any such waiver, it will be granted with respect to all option holders and tendered options in a uniform and nondiscriminatory manner. No tender of options will be deemed to have been made properly until all defects or irregularities have been cured or waived by us. We have no obligation to give notice of any defects or irregularities in any election and we will not incur any liability for failure to give any such notice. This is a one-time offer. We will strictly enforce the offering period, subject only to an extension that we may grant in our discretion.

Our acceptance constitutes an agreement

Your election to exchange options through the procedures described above constitutes your acceptance of the terms and conditions of this Offer. Our acceptance of your options for exchange will constitute a binding agreement between PMV and you upon the terms and subject to the conditions of this Offer.

You may change an election you previously made with respect to some or all of your eligible options, including an election to withdraw all of your eligible options from this Offer, only in accordance with the provisions of this section. You may change your mind after you have submitted an election and withdraw some or all of your elected eligible options from the Offer at any time before the expiration of the Offer, currently expected to be 11:59 p.m., Eastern Time, on August 13, 2024. If we extend the expiration date, you may change or withdraw your election of tendered options at any time until the extended Offer expires. In addition, although we intend to accept all validly tendered eligible options promptly after the expiration of this Offer, due to certain requirements under U.S. securities laws, if we have not accepted your options by 11:59 p.m., Eastern Time, on September 11, 2024 (which is the 40th U.S. business day following the commencement of the Offer), you may withdraw your options at any time thereafter up to such time as PMV does accept your properly tendered options.

19

To change an election you previously made with respect to some or all of your eligible option grants, including an election to withdraw all of your eligible option grants from this Offer, you must deliver a valid new election indicating only the eligible option grants you wish to exchange in the Offer or a valid new election indicating that you reject the Offer with respect to all of your eligible options, by completing the election process via the following method outlined below on or before the expiration of the Offer, currently expected to be 11:59 p.m., Eastern Time, on August 13, 2024.

Proper election changes and withdrawals

Election changes and withdrawals via the Offer website

You may change your mind as many times as you wish, but you will be bound by the properly submitted election we receive last on or before the expiration of the Offer, currently expected to be 11:59 p.m., Eastern Time, on August 13, 2024. Any options with respect to which you do not revise your election will be bound to your prior election.

If you change your election to withdraw some or all of your eligible option grants, you may elect later to exchange the withdrawn eligible option grants again at any time on or before the expiration of the Offer. All eligible option grants that you withdraw will be deemed not properly tendered for purposes of the Offer, unless you subsequently properly elect to exchange such eligible option grants on or before the expiration of the Offer. To reelect to exchange some or all of your eligible option grants, you must submit a new election form to PMV on or before the expiration of the Offer by following the procedures described in Section 4 of this Offer to Exchange. This new election must be properly submitted after your previously submitted election and must list all eligible option grants you wish to exchange. Upon our receipt of your properly submitted election, any prior election will be disregarded in its entirety and will be considered replaced in full by the new election.

Each time you make an election on the PMV Offer website, please be sure to make an election with respect to each of your eligible option grants.

Neither we nor any other person is obligated to give you notice of any defects or irregularities in any election, nor will anyone incur any liability for failure to give any notice.

Upon the terms and conditions of this Offer and promptly following the expiration of this Offer, we will accept for exchange and cancel all eligible options properly elected for exchange and not validly withdrawn before the expiration of this Offer. Once the eligible options are cancelled, you no longer will have any rights with respect to those eligible options. In addition, as discussed in Sections 9 and 14 of this Offer to Exchange, for U.S. federal income tax purposes, all new options will retain the same tax status as the corresponding eligible option cancelled in the Offer to the maximum extent permitted by law. In other words, incentive stock options will be exchanged for incentive stock options, and nonstatutory stock options will be exchanged for nonstatutory stock options, subject to applicable law. Subject to the terms and conditions of this Offer, if your eligible options are properly tendered by you for exchange and accepted by us, these eligible options will be cancelled as of the cancellation date, which we anticipate to be August 13, 2024.

For purposes of the Offer, we will be deemed to have accepted options for exchange that are validly tendered and are not properly withdrawn as of the expiration of the Offer and the cancellation date. Promptly following the expiration date and cancellation date, we will give oral or written notice to the option holders generally of our acceptance for exchange of the options. This notice may be made by press release, email or other method of communication. Subject to our rights to terminate the Offer, discussed in Section 15 of this Offer to Exchange, we currently expect that we will accept, promptly after the expiration of this Offer, all properly tendered options that are not validly withdrawn.

We will grant the new options on the new option grant date, which is the same calendar day as the cancellation date. We expect the new option grant date to be August 13, 2024. All new options granted to you will be granted under our 2020 Plan and will be subject to a new stock option agreement between you and PMV. The number of new options you will receive in exchange for your eligible options will cover the same number of shares of our common stock as the number of shares subject to the exchanged options. Shortly after the new option grant date, you will receive your new stock option agreement in the same manner as the Company provides any PMV options in the normal course. You should follow the same electronic procedures that ordinarily apply to any PMV options granted to you in the normal course. Your new options will become exercisable if and when your new options vest, in accordance with the vesting schedule described in Section 9 of this Offer to Exchange.

Options that we do not accept for exchange will remain outstanding until they are exercised or cancelled or expire by their terms and will retain their current exercise price, current vesting schedule and current term.

Notwithstanding any other provision of this Offer, we will not be required to accept any options tendered for exchange, and we may terminate the Offer, or postpone our acceptance and cancellation of any options tendered for exchange, in each case, subject to Rule 13e 4(f)(5) under the Exchange Act, if at any time on or after the date this Offer begins, and before the expiration date, any of the following events has occurred, or has been determined by us, in our reasonable judgment, to have occurred:

If any of the above events occur, we may:

Since the Offer involves the issuance of new options in exchange for eligible options, no financing arrangements are required as a condition to completing this Offer.

The conditions to this Offer are for our benefit. We may assert them in our discretion regardless of the circumstances giving rise to them before the expiration date. We may waive any condition, in whole or in part, at any time and from time to time before the expiration date, in our discretion, whether or not we waive any other condition to the Offer. Any such waiver will apply to all eligible employees in a uniform and nondiscretionary manner. Our failure at any time to exercise any of these rights will not be deemed a waiver of any such rights, but will be deemed a waiver of our ability to assert the condition that was triggered with respect to the particular circumstances under which we failed to exercise our rights. Any determination we make concerning the events described in this Section 7 will be given the maximum deference permitted by law. However, you have all rights accorded to you under applicable law to challenge such determination in a court of competent jurisdiction. Only a court of competent jurisdiction can make a determination that will be final and binding upon the parties.

Eligible options give eligible employees the right to acquire shares of our common stock. None of the eligible options are traded on any trading market. The PMV common stock that underlies your options is traded on Nasdaq under the symbol “PMVP.” The following table shows, for the periods indicated, the high and low sales price per share of our common stock as reported by Nasdaq.

On July 15, 2024, the last reported closing sales price of our common stock, as reported by Nasdaq, was $1.63 per share.

You should evaluate current market quotes for our common stock, among other factors, before deciding whether or not to accept this Offer.

23

Consideration

We will issue new options in exchange for eligible options properly elected to be exchanged by you and accepted by us for such exchange. Subject to the terms and conditions of this Offer, upon our acceptance of your properly tendered eligible options, you will be entitled to receive new options covering the same number of shares of our common stock as the number of shares subject to the exchanged options (with any fractional share rounded down to the nearest whole share). New options will be unvested as of the new option grant date and will be subject to a new vesting schedule as described below under “Vesting and Exercisability.”

If we receive and accept tenders from eligible employees of all options eligible to be tendered, subject to the terms and conditions of this Offer, options to purchase approximately 2,820,491 shares would be surrendered and cancelled, while new options covering approximately 2,820,491 shares of our common stock, or approximately 5% of the total shares of our common stock outstanding as of July 15, 2024, would be issued, assuming that the closing price of our common stock on the expiration date of this Offer is less than $4.36.

General terms of new options

All new options to be granted to you will be granted under, and subject to, the terms and conditions of our 2020 Plan and a stock option agreement between you and PMV thereunder. The terms and conditions of the new options will vary from the terms and conditions of the eligible options that you tendered for exchange, but the terms and conditions that will change generally will not substantially and adversely affect your rights. However, the new options have a different exercise price, vesting schedule, and maximum term. New options will be entirely unvested as of the new option grant date and will be subject to a new vesting schedule based on the grant date of each of your exchanged options, regardless of whether your exchanged options were wholly or partially vested, as described below under “Vesting and exercisability.”

For U.S. federal income tax purposes, all new options will retain the same tax status as the corresponding eligible option cancelled in the Offer to the maximum extent permitted by law. In other words, incentive stock options will be exchanged for incentive stock options, and nonstatutory stock options will be exchanged for nonstatutory stock options, subject to applicable law.

The following description summarizes the material terms of our 2020 Plan. Our statements in this Offer to Exchange concerning the 2020 Plan and the new options are merely summaries and do not purport to be complete. The statements are subject to, and are qualified in their entirety by reference to, the 2020 Plan, and the form of stock option agreement for grants made under the 2020 Plan. The 2020 Plan and form of stock option agreement thereunder are incorporated by reference as exhibits to the Schedule TO with which this Offer has been filed and are available on the SEC website at www.sec.gov. Please contact us at PMV Pharmaceuticals, Inc., 1 Research Way, Princeton, New Jersey 08540, Attention: Robert Ticktin, our General Counsel (telephone: (609) 642-6670), to receive a copy of the 2020 Plan, and the relevant form of stock option agreement thereunder. We will promptly furnish you copies of these documents upon request at our expense.

2020 Plan

Our 2020 Plan permits the grant of incentive stock options, nonstatutory stock options, restricted stock, stock appreciation rights, performance units and performance shares to our employees, directors and consultants. As of July 15, 2024, the maximum number of shares of our common stock subject to options currently outstanding under the 2020 Plan was approximately 6,442,955 shares. As of July 15, 2024, the maximum number of shares of our common stock available for future issuance under the 2020 Plan was approximately 7,579,365 shares. On the first day of each fiscal year of the Company beginning with the Company’s fiscal year 2021, the number of shares of our common stock reserved for issuance under the 2020 Plan is increased by an amount equal to the least of (i) 4,406,374 shares, (ii) five percent (5%) of the outstanding shares of our common stock on the last day of our immediately preceding fiscal year, or (iii) such number of shares determined by our 2020 Plan administrator before the last day of our immediately preceding fiscal year. The next increase of the shares of our common stock reserved for issuance under the 2020 Plan is scheduled to occur on January 1, 2025. The 2020 Plan is administered by the compensation committee of our board of directors, which we refer to as the administrator. Subject to the other provisions of the 2020 Plan, the administrator has the power to determine the terms, conditions, and restrictions of the options granted, including the number of options and the vesting schedule. The exercise price of an option granted under the 2020 Plan generally is determined by the administrator; provided, however, that the exercise price of an option shall in no event be less than 100% of the fair market value of a share of our common stock on the date of grant. The vesting applicable to an option granted under the 2020 Plan generally is determined by the administrator in accordance with the terms of the 2020 Plan. Options granted under the 2020 Plan generally have a maximum term of 10 years after the date of grant. New options granted pursuant to the terms and conditions of the Offer will have a maximum term of 10 years after the date of grant.

24

Exercise price

The exercise price of an option granted under the 2020 Plan generally is determined by the administrator; provided, however, that the exercise price of an option shall in no event be less than 100% of the fair market value of a share of our common stock on the date of grant. For purposes of this Offer, new options will have a per share exercise price equal to 100% of the closing sales price of a share of our common stock on Nasdaq on the new option grant date. The new option grant date is expected to be August 13, 2024.

Vesting and Exercisability

The vesting applicable to an option granted under the 2020 Plan generally is determined by the administrator in accordance with the terms of the 2020 Plan. The new options will be unvested as of the new option grant date and will be subject to a new vesting schedule. Each new option will be unexercisable while it remains unvested, regardless of whether the exchanged option was early exercisable. The vesting commencement date of all new options will be the new option grant date and the new options will be subject to additional vesting, in each case subject to your continued service with us through the applicable vesting dates, as follows.

In all cases described above, vesting is subject to your continued service to us through each vesting date. Your participation in this Offer and the receipt of new options does not provide any guarantee or promise of continued service with us. The maximum term of the new option grant will be 10 years from the new option grant date.

Example 1

For illustrative purposes only, assume that you are an eligible employee and that you exchange in the Offer an eligible option grant to purchase 3,600 shares of our common stock that was granted before April 30, 2022. There are no specific accelerated vesting terms that apply to your eligible option grant. Assume also that the Offer expires and new options are granted on August 13, 2024. Under the terms of the Offer, the new option grant will cover 3,600 shares, be entirely unvested upon the new option grant date, and have a vesting commencement date of August 13, 2024. The maximum term of the new option grant will be 10 years from August 13, 2024.

25

The new option grant will be scheduled to vest as to 1,200 shares on August 13, 2025, the 1-year anniversary of the new option grant date, and thereafter will vest as to 100 shares on each monthly anniversary of the new option grant date, subject to your continued service to us through each vesting date.

Example 2

For illustrative purposes only, assume that you are an eligible employee and that you exchange in the Offer an eligible option grant to purchase 4,800 shares of our common stock that was granted after April 30, 2022. There are no specific accelerated vesting terms that apply to your eligible option grant. Assume also that the Offer expires and new options are granted on August 13, 2024. Under the terms of the Offer, the new option grant will cover 4,800 shares, be entirely unvested upon the new option grant date and have a vesting commencement date of August 13, 2024. The maximum term of the new option grant will be 10 years from August 13, 2024.

The new option grant will be scheduled to vest as to 1,200 shares on August 13, 2025, the 1-year anniversary of the new option grant date, and thereafter will vest as to 100 shares on each monthly anniversary of the new option grant date, subject to your continued service to us through each vesting date.

Adjustments upon certain events

Events occurring before the new option grant date

Although we are not anticipating any merger or acquisition of PMV, if prior to the expiration of the Offer, we merge or consolidate with or are acquired by another entity, you may choose to change your election or withdraw any options which you tendered for exchange, and your options will be treated in accordance with the 2020 Plan and your stock option agreement. Further, if we are acquired prior to the expiration of the Offer, we reserve the right to withdraw the Offer, in which case your options and your rights under them will remain intact and exercisable for the time period set forth in your stock option agreement and applicable equity incentive plan or stock option plan, and you will receive no new options in exchange for them. If we are acquired prior to the expiration of the Offer but we (or the successor entity) do not withdraw the Offer, then we (or the successor entity) will notify you of any material changes to the terms of the Offer or the new options, including any adjustments to the exercise price and number and type of shares that will be subject to the new options.

Under such circumstances, the type of security and the number of shares covered by your new options and the new options’ exercise price would be adjusted based on the consideration per share given to holders of our common stock in connection with the acquisition. As a result of this adjustment, you may receive new options covering more or fewer shares of the acquirer’s common stock than the number of shares of our common stock subject to the eligible options that you tendered for exchange or than the number of shares of our common stock that would have been subject to the new options and greater or lesser per share exercise price of your new options, had no acquisition occurred.

26

If another company acquires us, that company, as part of the transaction or otherwise, may decide to terminate some or all of our employees before the completion of this Offer. Termination of your employment for this or any other reason before the new option grant date (which is the same calendar day as the expiration date) means that the tender of your options will not be accepted, you will keep your tendered options in accordance with their original terms, and you will not receive any new options or other benefit for your tendered options.

Events occurring after the new option grant date

If we are acquired after your exchanged options have been accepted, cancelled, and exchanged for new options, your new options will be treated in the acquisition transaction in accordance with the terms of the transaction agreement or the terms and conditions of our 2020 Plan and the stock option agreement between you and PMV thereunder. If we merge or consolidate with or are acquired by another entity, the transaction could result in a reduction in our workforce. If such termination of employment or other service occurs shortly after the expiration date, then you may hold new options that are entirely unvested, and all unvested new options will expire on such termination date. If your employment or other service with us terminates before part or all of your new options vest, you will not receive any value from the unvested part of your new options. If this termination of your employment or other service occurs shortly after the new option grant date and before you vest in any of your new options, you will forfeit your rights to your unvested new options as of the date of your termination of employment or other service and you will not receive any value from those new options.

In the event that any dividend or other distribution (whether in the form of cash, shares of our common stock, other securities, or other property), recapitalization, stock split, reverse stock split, reorganization, merger, consolidation, split-up, spin-off, combination, repurchase, or exchange of our common stock or other securities of PMV, or other change in our corporate structure affecting the shares of our common stock occurs, the administrator, in order to prevent diminution or enlargement of the benefits or potential benefits intended to be made available under the 2020 Plan, will appropriately adjust the number and class of shares that may be delivered under the 2020 Plan and/or the number, class, and price of shares covered by each outstanding award, and the numerical share limits of the 2020 Plan.

If we liquidate or dissolve, to the extent not previously exercised or settled, your outstanding options will terminate immediately before the consummation of the dissolution or liquidation. The administrator will notify award holders as soon as practicable prior to the effective date of such proposed liquidation or dissolution.

Our 2020 Plan provides that in the event of a merger or change in control of PMV as described in the 2020 Plan, each outstanding award will be treated as the administrator determines, including, without limitation, that each such award be assumed or an equivalent option or right substituted by the successor corporation or a parent or subsidiary of the successor corporation. The administrator will not be required to treat all awards similarly in the transaction.

In the event that the successor corporation does not assume or substitute for an award, the holder of such award will fully vest in and have the right to exercise such outstanding options, including shares as to which such award otherwise would not be vested or exercisable. In addition, if an option is not assumed or substituted in the event of a change in control of PMV, the administrator will notify the holder of such option in writing or electronically that the option will be exercisable for a period of time determined by the administrator in its sole discretion, and the option will terminate upon the expiration of such period. Awards granted under the 2020 Plan may be subject to other terms set forth in a written agreement between the award holder and PMV governing the terms of such awards in the event of a merger or other corporate transaction of PMV, as described in such agreement.

Transferability of options

Unless determined otherwise by the 2020 Plan’s administrator, an option may not be sold, pledged, assigned, hypothecated, transferred, or disposed of in any manner other than by will or by the laws of descent or distribution and may be exercised, during the lifetime of the holder of such option, only by such holder. If the administrator makes an option transferable, such option will contain such additional terms and conditions as the administrator deems appropriate.

Registration of shares underlying new options

All of the shares of PMV common stock issuable upon exercise of new options have been registered under the Securities Act on a registration statement on Form S-8 filed with the SEC. Unless you are an employee who is considered an affiliate of PMV for purposes of the Securities Act, you will be able to sell the shares issuable upon exercise of your new options free of any transfer restrictions under applicable U.S. securities laws.

Tax consequences

You should refer to Section 14 of this Offer to Exchange for a discussion of the U.S. federal income tax consequences of the new options and exchanged options, as well as the consequences of accepting or rejecting this Offer.

We strongly recommend that you consult with your own advisers to discuss the consequences to you of this transaction.

PMV is a precision oncology company pioneering the discovery and development of small molecule, tumor-agnostic therapies targeting p53. p53 mutations are found in approximately half of all cancers. The field of p53 biology was established by our co-founder Dr. Arnold Levine when he discovered the p53 protein in 1979. Bringing together leaders in the field to utilize over four decades of p53 biology, PMV combines unique biological understanding with pharmaceutical development focus.

We were incorporated in Delaware in March 2013 under the name “PJ Pharmaceuticals, Inc.” In July 2013, we changed our name to “PMV Pharmaceuticals, Inc.” Our principal executive offices are located at 1 Research Way, Princeton, New Jersey 08540. Our telephone number is (609) 642-6670. Our website address is www.pmvpharma.com. Information contained on the website is not incorporated by reference into this Offer to Exchange.

A list of our executive officers and members of our board of directors as of July 15, 2024, is attached to this Offer to Exchange as Schedule A. Non-employee members of our board of directors are not eligible to participate in this Offer. Our executive officers may participate in this Offer.

The following table sets forth the beneficial ownership of the Company’s executive officers and non-employee directors of eligible options outstanding, and the percentage of total eligible options outstanding beneficially owned by them, as of July 15, 2024, assuming that the closing price of our common stock on the expiration date of this Offer is less than $4.36.

During the 60-day period prior to the date of this Offer, neither we, nor, to the best of our knowledge, any member of our board of directors or any of our executive officers, nor any of our affiliates, has engaged in any transaction involving the eligible options.

28

Except as otherwise described in this Offer or in our filings with the SEC, other than outstanding options to purchase common stock and restricted stock units granted from time to time pursuant to our 2020 Plan or stock purchase rights granted from time to time pursuant to our employee stock purchase plan, neither we nor, to our knowledge, any of our directors or executive officers, is a party to any contract, arrangement, understanding or relationship with any other person with respect to any of our securities (including, but not limited to, any contract, arrangement, understanding or relationship concerning the transfer or the voting of any such securities, joint ventures, loan or option arrangements, puts or calls, guarantees of loans, guarantees against loss or the giving or withholding of proxies, consents or authorizations).

Exchanged options that we acquire through the Offer will be cancelled and, to the extent they were granted under the 2020 Plan, the shares of our common stock subject to those options will be returned to the pool of shares of our common stock available for grants of awards under the 2020 Plan, including any new options granted under the Offer. To the extent shares returning to the 2020 Plan are not fully reserved for issuance upon receipt of the new options to be granted in connection with the Offer, the shares will be available for issuance pursuant to future equity awards to employees and other eligible 2020 Plan participants without further stockholder action, except as required by applicable law or the rules of Nasdaq or any other securities quotation system or any stock exchange on which our shares are then quoted or listed.

We have adopted the provisions of Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) Topic 718, Stock Compensation (“Topic 718”). Under Topic 718, the Offer with respect to all eligible options is considered a modification of those options exchanged and as a result we may be required to recognize incremental compensation expense, if any, resulting from the new options granted in the Offer. The incremental compensation will be measured as the excess, if any, of the fair value of each new option granted to employees in exchange for the exchanged options, measured as of the date the new options are granted, over the fair value of the eligible options exchanged for the new options, measured immediately prior to the exchange. This incremental compensation expense will be recognized over the remaining requisite service period of the new options. In the event that any of the new options are forfeited prior to their vesting due to termination of employment or other service, any incremental compensation expense of the forfeited new options will not be recognized.

We are not aware of any license or regulatory permit that appears to be material to our business that might be adversely affected by our exchange of options and issuance of new options as contemplated by the Offer, or of any approval or other action by any government or governmental, administrative or regulatory authority or agency or any Nasdaq listing requirements that would be required for the acquisition or ownership of our options as contemplated herein. Should any additional approvals or notice filings or other actions be required, we presently contemplate that we will seek such approvals, make such filings or take such other actions. However, we cannot assure you that we will seek such approvals, make such filings or take such other actions or that any such approvals, filings or other actions, if needed, could be obtained or made or what the conditions imposed in connection with such approvals or filings would entail or whether the failure to obtain any such approvals, to make such filings or take any other actions would result in adverse consequences to our business. Our obligation under the Offer to accept tendered options for exchange and to issue new options for tendered options is subject to the conditions described in Section 7 of this Offer to Exchange.

If we are prohibited by applicable laws or regulations from granting new options or required to obtain a license or regulatory permit or make any other filing before granting new options on the new option grant date, we will not grant any new options, unless we obtain the necessary license or make the requisite filing. We are unaware of any such prohibition at this time which cannot be satisfied by obtaining a license or permit or making a filing, and we will use reasonable efforts to effect the grant, but if the grant is prohibited or seems not feasible to be made on the new option grant date, we will not grant any new options, and you will not receive any other benefit for the options you tendered.

Material U.S. federal income tax consequences

The following is a general summary of the material U.S. federal income tax consequences of participating in the exchange of options pursuant to the Offer for those eligible employees subject to U.S. federal income tax. This discussion is based on the Internal Revenue Code (the “Code”), its legislative history, treasury regulations thereunder, and administrative and judicial interpretations as of the date of this Offer to Exchange, all of which are subject to change, possibly on a retroactive basis. The federal tax laws may change and the federal, state, and local tax consequences for each eligible employee will depend upon his or her individual circumstances. This summary does not discuss all of the tax consequences that may be relevant to you in light of your particular circumstances, nor is it intended to be applicable in all respects to all categories of option holders.

29

We recommend that you consult your own tax adviser with respect to the U.S. federal, state, and local tax consequences of participating in the Offer, as the tax consequences to you are dependent on your individual tax situation.

If you are a citizen or resident of, or are otherwise subject to the tax laws of, another country, or change your residence or citizenship during the term of the Offer, the information contained in this discussion may not be applicable to you. You are strongly advised to seek appropriate professional advice as to how the tax or other laws in the United States apply to your specific situation. Please refer to Schedule C of this document if you reside outside the U.S.

New options

Eligible employees whose outstanding eligible options are exchanged for new options under the Offer should not be required to recognize income for U.S. federal income tax purposes at the time of the exchange. We believe that the exchange will be treated as a non-taxable event.

For U.S. federal income tax purposes, all new options will retain the same tax status as the corresponding eligible option cancelled in the Offer to the maximum extent permitted by law. In other words, incentive stock options will be exchanged for incentive stock options, and nonstatutory stock options will be exchanged for nonstatutory stock options, subject to applicable law.

Please note that the Code limits the annual benefit a single person may receive from incentive stock options, preventing more than $100,000 worth of incentive stock options from becoming exercisable for the first time in any one calendar year. For purposes of this $100,000 limit, the fair market value of the shares subject to each such option is determined as of the grant date of the option. To the extent more than $100,000 of options granted to a single individual as incentive stock options first become exercisable in any calendar year, the portions of these options in excess of $100,000 are treated as nonstatutory stock options for U.S. federal income tax purposes.

For the purposes of the $100,000 limit described above, a special rule applies with respect to incentive stock options that are cancelled in the year such options are cancelled. As a result of that special rule, any eligible options cancelled in the Offer that were incentive stock options and that vested or were scheduled to vest in 2024 will count against the $100,000 limit based on the fair market value of a share of our common stock on the grant date of that original eligible option. Therefore, if you exchange eligible options in the Offer that are incentive stock options, your $100,000 limit for 2024 will be reduced by options that are cancelled and no longer eligible to be exercised. Your new options will be incentive stock options only to the extent you do not exceed the $100,000 limit; any excess portions of your new options will be treated as nonstatutory stock options.

Eligible service providers who do not participate in the Offer

Under the U.S. tax rules governing incentive stock options, if an offer to modify an incentive stock option remains outstanding for 30 or more calendar days, then the incentive stock option is deemed modified regardless of whether you participate in the Offer. The Offer currently is expected to remain open for less than 30 calendar days. If this Offer is extended and remains open for at least 30 calendar days, eligible options that are incentive stock options held by U.S. employees who do not participate in this Offer will be considered to have been modified. In such event, the commencement date of the Offer (July 16, 2024) will be considered the modification date for purposes of determining whether the employee will receive favorable tax treatment with respect to the eligible options that are incentive stock options. Accordingly, in order to receive favorable tax treatment with respect to any such incentive stock option that is, as of the modification date, “underwater” (meaning the exercise price of such option is greater than our then-current stock price) or “at-the-money” (meaning the exercise price of such option is equal to our then-current stock price), you would be required not to dispose of any shares of our common stock acquired with respect to the incentive stock option until the passage of more than two years from the date this Offer commenced (July 16, 2024) (i.e., the date of the deemed modification) and more than one year after the exercise of the option. If these holding periods (and all other incentive stock option requirements) are met, the excess of the sale price of the option shares over the exercise price of the option will be treated as long-term capital gain. Further, if, as of the modification date, you are no longer an employee or your eligible option is “in-the-money” (meaning our stock price is greater than the exercise price of the options) as of the modification date, such eligible option will immediately cease to be an incentive stock option and instead be deemed a nonstatutory stock option. For more detailed information, please see the information below.

Incentive stock options

Under current U.S. tax law, an option holder generally will not realize taxable income upon the grant of an incentive stock option. In addition, an option holder generally will not realize taxable income upon the exercise of an incentive stock option. However, the exercise of an incentive stock option may affect an option holder’s alternative minimum taxable income. Upon exercise of an incentive stock option, the option holder will be required to include the amount equal to the excess of the fair

30

market value of the exercised shares on the date of exercise over the exercise price as an adjustment item in the determination of any alternative minimum tax. However, if the option holder disposes of the exercised shares in the same calendar year as the date of exercise of the incentive stock option, then no adjustment will be made in determining such alternative minimum tax. Except in the case of an option holder’s death or disability, if an option is exercised more than three months after the option holder’s termination of employment, the option ceases to be treated as an incentive stock option and is subject to taxation under the rules that apply to nonstatutory stock options.

If an option holder sells the option shares acquired upon exercise of an incentive stock option, the tax consequences of the disposition depend upon whether the disposition is qualifying or disqualifying. The disposition of the option shares is qualifying if it is made:

If the disposition of the option shares is qualifying, any excess of the sale price of the option shares over the exercise price of the option will be treated as long-term capital gain taxable to the option holder at the time of the sale. Any such capital gain will be taxed at the long-term capital gain rate in effect at the time of sale.

If the disposition is not qualifying, which we refer to as a “disqualifying disposition,” the excess of the fair market value of the option shares on the date the option was exercised (or, if less, the amount realized on the disposition of the shares) over the exercise price will be treated as ordinary income to the option holder at the time of the disposition. Any additional gain generally will be taxable at long-term or short-term capital gain rates, depending on whether the option holder has held the shares for more than one year.

Unless an option holder engages in a disqualifying disposition, we will not be entitled to a deduction with respect to an incentive stock option. If an option holder engages in a disqualifying disposition, we generally will be entitled to a deduction equal to the amount of ordinary income taxable to the option holder.

Nonstatutory stock options

Under current U.S. tax law, an option holder generally will not realize taxable income upon the grant of a nonstatutory stock option. However, when an option holder exercises the nonstatutory stock option, the difference between the exercise price of the option and the fair market value of the shares subject to the option on the date of exercise generally will be compensation income taxable to the option holder.

We generally will be entitled to a deduction equal to the amount of compensation income taxable to the option holder if we comply with eligible reporting requirements.

Upon disposition of the exercised shares, any gain or loss is treated as capital gain or loss. The capital gain or loss will be long-term or short-term depending on whether the shares were held for more than 12 months. The holding period for the shares generally will begin just after the time the option holder recognized income. The amount of such gain or loss will be the difference between: (i) the amount realized upon the sale or exchange of the shares, and (ii) the value of the shares at the time the ordinary income was recognized.

If the option holder was an employee at the time of the grant of the option, any income recognized upon exercise of a nonstatutory stock option generally will constitute wages for which withholding will be required.

We recommend that you consult your tax adviser with respect to the U.S. federal, state, and local tax consequences of participating in the Offer.

IF YOU RESIDE OUTSIDE THE UNITED STATES THE INFORMATION CONTAINED IN THIS SECTION MAY NOT BE APPLICABLE TO YOU. YOU ARE ADVISED TO REVIEW THE COUNTRY SPECIFIC DISCLOSURES IN SCHEDULE C ATTACHED HERETO AND TO CONSULT WITH AN APPROPRIATE PROFESSIONAL ADVISOR AS TO HOW LOCAL TAX OR OTHER LAWS OF YOUR COUNTRY OF RESIDENCE APPLY TO YOUR SPECIFIC SITUATION.

PLEASE NOTE THAT TAX LAWS CHANGE FREQUENTLY AND VARY WITH INDIVIDUAL CIRCUMSTANCES AND INDIVIDUAL FOREIGN JURISDICTIONS. PLEASE CONSULT A TAX ADVISOR TO DETERMINE THE TAX CONSIDERATIONS RELEVANT TO YOUR PARTICIPATION IN THIS OFFER.

We reserve the right, in our discretion, at any time and regardless of whether or not any event listed in Section 7 of this Offer to Exchange has occurred or is deemed by us to have occurred, to extend the period of time during which the Offer is open and delay the acceptance for exchange of any options. If we elect to extend the period of time during which this Offer is open, we will give you oral or written notice of the extension and delay, as described below. If we extend the expiration date, we also will extend your right to withdraw tenders of eligible options until such extended expiration date. In the case of an extension, we will issue a press release, email or other form of communication no later than 9:00 a.m., Eastern Time, on the next U.S. business day after the previously scheduled expiration date.

31

We also reserve the right, in our reasonable judgment, before the expiration date to terminate or amend the Offer and to postpone our acceptance and cancellation of any options elected to be exchanged if any of the events listed in Section 7 of this Offer to Exchange occurs, by giving oral or written notice of the termination or postponement to you or by making a public announcement of the termination. Our reservation of the right to delay our acceptance and cancellation of options elected to be exchanged is limited by Rule 13e 4(f)(5) under the Exchange Act which requires that we must pay the consideration offered or return the options promptly after termination or withdrawal of a tender offer.

Subject to compliance with applicable law, we further reserve the right, before the expiration date, in our discretion, and regardless of whether any event listed in Section 7 of this Offer to Exchange has occurred or is deemed by us to have occurred, to amend the Offer in any respect, including by decreasing or increasing the consideration offered in this Offer to option holders or by decreasing or increasing the number of options being sought in this Offer. As a reminder, if a particular option grant expires after the beginning of the offering period, but before the cancellation date, that particular option grant is not eligible for exchange. Therefore, if we extend the Offer for any reason and if a particular option that was tendered before the originally scheduled expiration of the Offer expires after such originally scheduled expiration date, but before the actual expiration date under the extended Offer, that option would not be eligible for exchange.

The minimum period during which the Offer will remain open following material changes in the terms of the Offer or in the information concerning the Offer, other than a change in the consideration being offered by us or a change in the amount of existing options sought, will depend on the facts and circumstances of such change, including the relative materiality of the terms or information changes. If we modify the number of eligible options being sought in this Offer or the consideration being offered by us for the eligible options in this Offer, the Offer will remain open for at least 10 U.S. business days from the date of notice of such modification. If any term of the Offer is amended in a manner that we determine constitutes a material change adversely affecting any holder of eligible options, we will promptly disclose the amendments in a manner reasonably calculated to inform holders of eligible options of such amendment, and we will extend the offering period so that at least five U.S. business days, or such longer period as may be required by the tender offer rules, remain after such change.

For purposes of the Offer, a “business day” means any day other than a Saturday, Sunday or a U.S. federal holiday and consists of the time period from 12:01 a.m. through 12:00 midnight, Eastern Time.

We will not pay any fees or commissions to any broker, dealer or other person for soliciting options to be exchanged through this Offer.

A GUIDE TO TAX & LEGAL ISSUES FOR NON-U.S. EMPLOYEES

SWITZERLAND

The following is a discussion of the material tax consequences of participating in the exchange of eligible options and the grant of new options pursuant to the Offer for eligible employees subject to tax in Switzerland. This discussion is general in nature and does not discuss all of the tax consequences that may be relevant to you in light of your particular circumstances, nor is it intended to be applicable in all respects to all categories of eligible employees. Please note that tax laws and practices change frequently and occasionally on a retroactive basis. As a result, the information contained in this discussion may be out of date at the time the new options are granted, you exercise the new options or you sell shares acquired upon exercise of any new options.

If you are a citizen or resident of more than one country, or are considered a resident of more than one country for local law purposes, the information contained in this discussion may not be applicable to you. You are strongly advised to seek appropriate professional advice as to how the tax or other laws or practices in Switzerland apply to your specific situation.

Tax Information

Option Exchange

You will not be subject to tax as a result of the exchange of eligible options for the new options.

Grant of New Options

You will not be subject to tax when the new options are granted to you.

Exercise of New Options

When you exercise your new options in accordance with their terms, you will realize taxable income for purposes of income tax and social insurance contributions equal to the excess of (a) the fair market value of the purchased shares on the exercise date over (b) the exercise price paid for those shares.

Withholding and Reporting

Your employer may be required to withhold social insurance contributions on income recognized and may be required to withhold income tax liability, notably if you are a foreign employee holding a “B” permit.

Exhibit (a)(1)(B)

Email to All Eligible Employees

Dear PMV Eligible Employee:

You are receiving this email because you are eligible to participate in a voluntary, one-time stock option exchange offer (the “Offer”) from PMV Pharmaceuticals, Inc. (“PMV”) that will allow you to exchange certain out-of-the-money stock options that you hold for new stock options with a new exercise price, as described in more detail below, and also in the attached documents including the “Offer to Exchange Certain Outstanding Stock Options for New Stock Options.”

If you elect to exchange your eligible options, you will receive new options that cover the same number of shares of common stock as the options that you exchange. The exercise price of the new options will be equal to the closing price of our common stock on Nasdaq on the Offer’s expiration date, which is August 13, 2024 (unless we choose to extend the Offer). For U.S. federal income tax purposes, all new options will retain the same tax status as the corresponding eligible option cancelled in the Offer to the maximum extent permitted by law. In other words, incentive stock options will be exchanged for incentive stock options, and nonstatutory stock options will be exchanged for nonstatutory stock options, subject to applicable law. The maximum term of the new option grant will be 10 years from the new option grant date. New options will be unvested on the new option grant date, regardless of whether your exchanged options were vested or unvested. The new options will be scheduled to vest on the following schedule, subject to you continuing your employment with us through each applicable vesting date:

All eligible employees who participate in the Offer will receive new options in exchange for their cancelled eligible options. Eligible options include only those options with an exercise price greater than $4.36 and were granted to you after September 29, 2020 (the date of our initial public offering). You are an eligible employee if you are an employee of PMV who holds eligible options as of the date the Offer commences and remain an employee of PMV through the new option grant date. However, consultants and non-employee members of our board of directors will not be eligible employees.

For those residing outside the United States, we urge you to educate yourselves about the financial and tax consequences of participating in this exchange by consulting with an appropriate advisor. PMV makes no representations regarding the financial or tax consequences of your participation in the Offer.

This Offer currently is scheduled to expire on August 13, 2024, at 11:59 p.m., Eastern Time, and new options are scheduled to be granted on the same calendar day.

We have prepared a number of resources to help you understand the terms and conditions of the Offer. These resources include the Offer to Exchange and election terms and conditions, together with their associated instructions. Each of these documents is attached to this email. In addition, to help you recall which of your options are eligible for exchange in this Offer and give you the information necessary to make an informed decision, please refer to your personalized information regarding each eligible option grant you hold available via PMV’s Offer website that lists:

Participation in the Offer is completely voluntary. Participating in the Offer involves risks that are discussed in the Offer to Exchange. We know that the materials describing the Offer may seem voluminous, but it is important that you carefully review these materials so that you can make an informed decision on whether or not to participate in the Offer. We believe this Offer is potentially very important to you and recommend that you take the time to study the materials, ask questions if needed, and make an informed decision about whether or not to participate. Additional resources relating to the Offer are available on the Offer website.

If you want to participate in the Offer, we must receive your election via PMV’s Offer website at www.myoptionexchange.com no later than 11:59 p.m., Eastern Time, on August 13, 2024 (unless the offering period is extended).

If you do not remain employed with PMV through the date that the new options are granted, then upon the termination of your employment, you will cease to be an eligible employee under the terms of the Offer and any election that you have made to exchange any of your options pursuant to the Offer will be ineffective. As a result, none of your options will be exchanged under the Offer and you will not receive new options.

If you do nothing, or if we have not received your properly completed and submitted election by the expiration of the Offer, you will have rejected this Offer and you will keep your current options. In that case, nothing will change about your existing options; they will remain outstanding and retain their existing terms.

You will receive an invitation to an information session on the Offer to be held later today (July 16, 2024 at 12:00 p.m. Eastern Time). We strongly encourage that you attend this information session. However, please understand that we cannot advise you on whether or not to participate in the Offer. Participation in the Offer is entirely your decision and at your discretion, and you should make the decision about whether to participate based on your personal circumstances. We recommend that you consult your personal financial, legal and/or tax advisors to address questions regarding your decision whether to participate in the Offer.

If, after you’ve read this message and accompanying materials, you still have questions, please contact Robert Ticktin, our General Counsel, by email at optionexchange@pmvpharma.com or by phone at (609) 642-6670.

Exhibit (a)(1)(C)

PMV PHARMACEUTICALS, INC.

OFFER TO EXCHANGE CERTAIN OUTSTANDING STOCK OPTIONS

FOR NEW STOCK OPTIONS

ELECTION TERMS AND CONDITIONS

1. I agree that my decision to accept or reject the Offer with respect to some or all of my eligible option grants is entirely voluntary and is subject to the terms and conditions of the Offer.

2. I understand that I may change my election at any time by completing and submitting a new election no later than 11:59 p.m. Eastern Time, on August 13, 2024 (unless the Offer is extended), and that any election submitted and/or received after such time will be void and of no further force and effect.

3. If my employment with PMV terminates on or before the date the Offer expires, I understand that I will cease to be an eligible employee under the terms of the Offer and any election that I have made to exchange any of my options pursuant to the Offer will be ineffective. As a result, none of my options will be exchanged under the Offer and I will not receive new options.

4. I understand and agree that my employment (or, after new options have been granted pursuant to the Offer, my employment or other service) with PMV will be considered terminated effective as of the date that I no longer am actively providing employment services (or other services, as applicable) to PMV, regardless of the reason for such termination and whether or not later found to be invalid or in breach of employment laws in the jurisdiction where I am employed or rendering services or the terms of my employment or other service agreement, if any; and unless otherwise expressly provided in the Offer documents or determined by PMV, my right to receive new options pursuant to the Offer or to vest in the new options received in the Offer, if any, will terminate as of such date and will not be extended by any notice period mandated under local law (e.g., my period of service would not include any contractual notice period or any period of “garden leave” or similar period mandated under employment laws in the jurisdiction where I am employed or rendering services or the terms of my employment or other service agreement, if any); PMV will have the exclusive discretion to determine when I no longer am actively providing employment services for purposes of the Offer and the grant of new options pursuant to the Offer (including whether I still may be considered to be providing employment services while on a leave of absence). I further acknowledge that the new options granted pursuant to the Offer have a different vesting schedule than the eligible options cancelled in exchange, that the first vesting date under the new options is scheduled to occur no earlier than the one-year anniversary of the new option grant date, and that any new options granted pursuant to the Offer will have a different exercise price per share of our common stock than the eligible options cancelled in the Offer.

5. I agree that all decisions with respect to future grants under any PMV equity compensation plan will be at the sole discretion of PMV.

6. I agree that: (i) the Offer is established voluntarily by PMV, is discretionary in nature and may be modified, amended, suspended or terminated by PMV, in accordance with the terms set forth in the Offer documents, at any time prior to the expiration of the Offer; (ii) PMV, at its discretion, may refuse to accept my election to participate; and (iii) the Offer is an exceptional, voluntary and one-time offer that does not create any contractual or other right to receive future offers, options or other equity awards, or benefits in lieu of offers, even if offers have been made in the past.

7. I agree that the new options, and income from and value of same; (i) are not intended to replace any pension rights or compensation; and (ii) are not part of normal or expected compensation for the purposes of calculating any severance, resignation, termination, redundancy, dismissal, end of service payments, bonuses, long-service awards, pension or retirement or welfare benefits or similar payments.

8. This election and my participation in the Offer shall not create a right to employment or other service, or be interpreted as forming or amending an employment or other service contract with PMV and shall not interfere with the ability of PMV, or, if different, of my current employer, or applicable entity with which I am engaged to provide services (the “Employer”), to terminate my employment or other service relationship (if any) at any time with or without cause (subject to the terms of my employment contract or other service contract, if any).

9. I understand that: (i) the future value of the shares of PMV’s common stock underlying the new options is unknown, indeterminable and cannot be predicted with certainty; (ii) if the underlying shares of PMV’s common stock do not increase in value, the new options will have no value; and (iii) if I exercise the new option and acquire shares of PMV’s common stock, the value of those shares may increase or decrease, even below the new option’s exercise price.

10. No claim or entitlement to compensation or damages shall arise from forfeiture of the new options resulting from the termination of my employment or other service relationship with PMV (for any reason whatsoever, whether or not later found to be invalid or in breach of employment laws in the jurisdiction where I am employed or the terms of my employment agreement, if any).

11. I acknowledge that, regardless of any action taken by PMV or the Employer, the ultimate liability for all income tax, social insurance and social security liabilities or premium, payroll tax, fringe benefits tax, payment on account or other tax-related items related to the Offer and the new options and legally applicable to me (“Tax-Related Items”) is and remains solely my responsibility and may exceed the amount actually withheld by PMV or the Employer. I further acknowledge that PMV and/or the Employer (i) make no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of the Offer and the new options, including, but not limited to, the exchange of eligible options for new options, the grant, vesting or exercise of the new options, the issuance of shares of PMV’s common stock upon exercise of the new options, the subsequent sale of shares of PMV’s common stock acquired pursuant to such issuance and the receipt of any dividends; and (ii) do not commit to and are under no obligation to structure the terms of the Offer or any aspect of the new options to reduce or eliminate my liability for Tax-Related Items or achieve any particular tax result. Further, if I am subject to tax in more than one jurisdiction, I acknowledge that PMV and/or the Employer (or former employer or entity, as applicable) may be required to withhold or account for Tax-Related Items in more than one jurisdiction.

Prior to any relevant taxable or tax withholding event, as applicable, I agree to make adequate arrangements satisfactory to PMV and/or the Employer to satisfy all Tax-Related Items. In this regard, I authorize PMV and/or the Employer, or their respective agents, at their discretion, to satisfy any applicable withholding obligations with regard to all Tax-Related Items by one or a combination of the following: (i) withholding from my wages or other cash compensation paid to me by PMV and/or the Employer; (ii) withholding from proceeds of the sale of shares of PMV’s common stock acquired upon exercise of the new options either through a voluntary sale or through a mandatory sale arranged by PMV (on my behalf pursuant to this authorization without further consent); or (iii) as otherwise specified in the 2020 Plan and the applicable stock option agreement between PMV and me governing the new options.

Finally, I agree to pay to PMV or the Employer any amount of Tax-Related Items that PMV or the Employer may be required to withhold as a result of my participation in the Offer and the grant of new options that cannot be satisfied by the means previously described. PMV may refuse to issue or deliver the shares of PMV’s common stock subject to new options that I receive pursuant to the Offer, if I fail to comply with my obligations in connection with the Tax-Related Items.

12. I acknowledge and agree that none of PMV or an affiliate of PMV, or any of their respective employees or agents, has made any recommendation to me as to whether or not I should accept the Offer to exchange my eligible options and that I am not relying on any information or representation made by any such person in accepting or rejecting the Offer, other than any information contained in the Offer documents.

13. I agree that participation in the Offer is governed by the terms and conditions set forth in the Offer documents, including this election form. I acknowledge that I have received the Offer documents and have been afforded the opportunity to consult with my own investment, legal and/or tax advisers before making this election and that I have knowingly accepted or rejected the Offer. I agree that any and all decisions or interpretations of PMV upon any questions relating to the Offer and this election form will be given the maximum deference permitted by law.

14. I agree that the terms of the new options, if any, that I receive pursuant to the Offer will be subject to the terms and conditions of the applicable new stock option agreement.

15. I understand and agree that the Offer and the new options granted pursuant to the Offer are governed by, and subject to, the laws of the State of New York, without regard to the conflict of law provisions. For purposes of litigating any dispute that arises directly or indirectly from the relationship of the parties evidenced by this Offer or the grant of new options, the parties hereby submit to and consent to the exclusive jurisdiction of the State of New York and agree that such litigation will be conducted only in the courts of New York, or the federal courts for the United States for the Southern District of New York, and no other courts, where this Offer is made and/or to be performed.

16. I further understand that if I submit my election via the Offer website, the confirmation statement provided on the Offer website at the time I submit my election will provide additional evidence that I submitted my election and that I should print and keep a copy of such confirmation statement for my records. A copy of the confirmation statement will also be sent to your email. If I do not receive a confirmation from PMV, I understand that it is my responsibility to ensure that my election form has been received no later than 11:59 p.m., Eastern Time, on August 13, 2024. I understand that only responses that are properly completed and submitted and actually received by PMV on or before the expiration date will be accepted.

17. The provisions of the Offer documents and this election form are severable and if any one or more provisions are determined to be illegal or otherwise unenforceable, in whole or in part, the remaining provisions nevertheless shall be binding and enforceable.

BY PARTICIPATING, YOU AGREE TO ALL TERMS OF THE OFFER AS SET FORTH IN THE OFFER DOCUMENTS. Please be sure to follow the instructions, which are attached.

ELECTION INSTRUCTIONS

FORMING PART OF THE TERMS AND CONDITIONS OF THE OFFER

If you want to participate in this Offer, you must make an election via the process described in Section 4 of the Offer to Exchange and outlined below on or before the expiration date, currently expected to be 11:59 p.m., Eastern Time, on August 13, 2024. If you do not want to participate, then no action is necessary.

Elections via the Offer Website

We must receive your properly completed and submitted election by the expiration of the Offer, currently expected to be 11:59 p.m., Eastern Time, on August 13, 2024. If you are unable to submit your election via the Offer website as a result of technical failures of the Offer website such as the Offer website being unavailable or the Offer website not enabling you to submit your election, please contact Asia Higgins, our Assistant Controller, or Keri Smith, our Senior Manager, Accounting, by email at optionexchange@pmvpharma.com or by phone at (609) 642-6670.

Your delivery of all documents regarding the Offer, including elections, is at your risk. A confirmation statement will be generated by the Offer website at the time that you complete and submit your election. You should print and keep a copy of the confirmation statement for your records. A copy of the confirmation statement will also be sent to your email. The printed confirmation statement will provide evidence that you submitted your election. If you do not receive a confirmation, it is your responsibility to confirm that we have received your election. If you do not receive a confirmation, we recommend that you confirm that we have received your election by contacting Asia Higgins, our Assistant Controller, or Keri Smith, our Senior Manager, Accounting, by email at optionexchange@pmvpharma.com or by phone at (609) 642-6670. Only responses that are properly completed and actually received by us by the deadline through the Offer website at www.myoptionexchange.com will be accepted. Responses submitted by any other means, including hand delivery, interoffice, email, U.S. mail (or other post) and Federal Express (or similar delivery service), are not permitted.

Our receipt of your election is not by itself an acceptance of your options for exchange. For purposes of the Offer, we will be deemed to have accepted options for exchange that are validly elected to be exchanged and are not properly withdrawn as of the time when we give oral or written notice to the option holders generally of our acceptance of options for exchange. We may issue this notice of acceptance by press release, email or other form of communication. Options accepted for exchange will be cancelled on the cancellation date, which we presently expect will be August 13, 2024.

PMV will not accept any alternative, conditional or contingent tenders. Any confirmation of receipt provided to you merely will be a notification that we have received your election form and does not mean that your eligible options have been cancelled. Your eligible options that are accepted for exchange will be cancelled on the same calendar day as the expiration of the Offer (but following the expiration of the Offer), which cancellation is scheduled to be August 13, 2024 (unless the Offer is extended).

You may change an election you previously made with respect to some or all of your eligible option grants, including an election to withdraw all of your eligible option grants from this Offer, only in accordance with the provisions of Section 5 of the Offer to Exchange. You may change your mind after you have submitted an election and withdraw some or all of your elected eligible options from the Offer at any time on or before the expiration date (the expiration date currently is expected to be August 13, 2024, at 11:59 p.m., Eastern Time). If we extend the expiration date, you may change or withdraw your election of your tendered options at any time until the extended Offer expires. In addition, although we intend to accept all validly tendered eligible options promptly after the expiration of this Offer, due to certain requirements under U.S. securities laws, if we have not accepted your options by 11:59 p.m., Eastern Time, on September 11, 2024 (which is the 40th U.S. business day following the commencement of the Offer), you may withdraw your options at any time thereafter up to such time as PMV does accept your properly tendered eligible options.

You may change your election and elect to exchange all of your eligible option grants, some of your eligible option grants, or none of your eligible option grants pursuant to the terms and conditions of this Offer. To change an election you previously made with respect to some or all of your eligible option grants, including an election to withdraw all of your eligible option grants from this Offer, you must deliver a valid new election indicating only the eligible option grants you wish to exchange in the Offer or a valid new election indicating that you reject the Offer with respect to all of your eligible options, by completing the election process set forth in Section 5 of the Offer to Exchange and described below on or before the expiration date, currently expected to be 11:59 p.m., Eastern Time, on August 13, 2024.

Election Changes and Withdrawals via the Offer Website

You may change your mind as many times as you wish, but you will be bound by the properly submitted election we receive last on or before the expiration date. If you change your election to withdraw some or all of your eligible option grants, you may elect later to exchange the withdrawn eligible option grants again at any time on or before the expiration date. All eligible option grants that you withdraw will be deemed not properly tendered for purposes of the Offer, unless you subsequently properly elect to exchange such eligible option grants on or before the expiration date. To reelect to exchange some or all of your eligible option grants, you must submit a new election to PMV on or before the expiration date by following the procedures described in Section 4 of the Offer to Exchange. This new election must be properly completed and actually received by us by the deadline on the Offer website at www.myoptionexchange.com to be accepted. Each time you make an election on the PMV Offer website, please be sure to make an election with respect to each of your eligible option grants.

If you intend to tender an eligible option grant through the Offer, you must tender all of your shares of PMV’s common stock subject to that eligible option grant.

You may pick and choose which of your outstanding eligible option grants you wish to exchange if you hold more than one eligible option grant and you may choose to exchange in the Offer one or more of your eligible option grants without having to exchange all of your eligible option grants. However, if you decide to participate in this Offer to exchange an eligible option grant, you must elect to exchange that entire eligible option grant (that is, all eligible options subject to that eligible option grant).

However, if you have an eligible option grant that is subject to a domestic relations order (or comparable legal document as the result of the end of a marriage) and a person who is not an eligible employee beneficially owns a portion of that eligible option grant, then in order to participate in the Offer with respect to such eligible option grant, you may accept this Offer with respect to the entire remaining outstanding portion of the eligible option grant, including the portion beneficially owned

by the other person, as long as you are the legal owner of the eligible option grant. We will not accept partial tenders of option grants, so you may not accept this Offer with respect to a portion of an eligible option grant that is beneficially owned by you while rejecting it with respect to the portion beneficially owned by someone else. As you are the legal owner of the eligible option grant, we will respect an election properly made by you, but will not be responsible to you or the beneficial owner of the eligible option grant for any errors made by you with respect to such eligible option grant.

Logging in to the Offer website and completing and submitting your election via the Offer website is the equivalent of signing your name on a paper election form and has the same legal effect as your written signature.

If the election form is signed by a trustee, executor, administrator, guardian, attorney in-fact, officer of a corporation or other person acting in a fiduciary or representative capacity, that person should so indicate when signing, and proper evidence satisfactory to PMV of the authority of that person to act in that capacity must be submitted with the election form.

When submitting the election via the Offer website, please confirm that your name, email address, and other information are correct.

Any questions and any requests for additional copies of the election form or other Offer documents may be directed to Asia Higgins, our Assistant Controller, or Keri Smith, our Senior Manager, Accounting, by email at optionexchange@pmvpharma.com or by phone at (609) 642-6670. Copies will be furnished promptly at PMV’s expense.

We will determine, in our discretion, all questions about the validity, form, eligibility (including time of receipt) and acceptance of any eligible options. Our determination of these matters will be given the maximum deference permitted by law. However, you have all rights accorded to you under applicable law to challenge such determination in a court of competent jurisdiction. Only a court of competent jurisdiction can make a determination that will be final and binding upon the parties. We reserve the right to reject any election of any option tendered for exchange that we determine is not in an appropriate form or that we determine is unlawful to accept. We will accept all properly tendered eligible options that are not validly withdrawn, subject to the terms of this Offer. We also reserve the right to waive any of the conditions of the Offer or any defect or irregularity in any tender of any particular options or for any particular option holder, provided that if we grant any such waiver, it will be granted with respect to all option holders and tendered options in a uniform and nondiscriminatory manner. No tender of options will be deemed to have been made properly until all defects or irregularities have been cured or waived by us. We have no obligation to give notice of any defects or irregularities in any election and we will not incur any liability for failure to give any such notice. This is a one-time offer. We will strictly enforce the offering period, subject only to an extension that we may grant in our discretion.

Important: Elections must be received via the Offer website at www.myoptionexchange.com on or before 11:59 p.m., Eastern Time, on August 13, 2024 (unless the Offer is extended).

You should be sure to read the Offer to Exchange, all documents referenced therein, the election form and its associated instructions, and the Launch Email, before deciding to participate in the Offer.

Please refer to Section 14 of the Offer to Exchange which contains important tax information. We also recommend that you consult with your personal advisers before deciding whether or not to participate in this Offer.

Options accepted for exchange will be cancelled on the cancellation date, which we presently expect will be August 13, 2024.

The full terms of the Offer are described in (1) the Offer to Exchange Certain Outstanding Stock Options for New Stock Options; (2) the launch email from David H. Mack, Ph.D., our President and Chief Executive Officer, dated July 16, 2024, announcing the Offer; and (3) the election terms attached to the launch email, together with its associated instructions.
