 Exhibit 10.18 

VAPOTHERM, INC. 

2018 EQUITY INCENTIVE PLAN 

 

	1.	 DEFINED TERMS 

Exhibit A, which is incorporated by reference, defines certain terms used in the Plan and sets forth operational rules related to those
terms. 
  

	2.	 PURPOSE 

The Plan is intended to advance the interests of the Company by providing for the grant to Participants of Stock and Stock-based Awards. The
purposes of the Plan are to attract, retain, and reward key Employees and Directors of, and consultants and advisors to, the Company and its subsidiaries, to incentivize them to generate stockholder value, to enable them to participate in the growth
of the Company and to align their interests with the interests of the Company’s stockholders. 
  

	3.	 ADMINISTRATION 

The Plan will be administered by the Administrator. The Administrator has discretionary authority, subject only to the express provisions of
the Plan, to administer and interpret the Plan and any Awards; to determine eligibility for and grant Awards; to determine the exercise price, base value from which appreciation is measured, or purchase price, if any, applicable to any Award; to
determine, modify or waive the terms and conditions of any Award; to determine the form of settlement of Awards (whether in cash, shares of Stock, other Awards, or other property); to prescribe forms, rules and procedures relating to the Plan and
Awards; and to otherwise do all things necessary or desirable to carry out the purposes of the Plan and any Awards. Determinations of the Administrator made with respect to the Plan or any Award are conclusive and bind all persons. 

 

	4.	 LIMITS ON AWARDS UNDER THE
PLAN 

 (a) Number of Shares. Subject to adjustment as provided in
Section 7(b), the number of shares of Stock that may be issued in satisfaction of Awards under the Plan is 998,900 shares of Stock (the “Initial Share Pool”). The Initial Share Pool will automatically increase (i) by the
number of shares of Stock underlying awards under the Prior Plan (which will not exceed 769,419 shares) that on or after the Date of Adoption expire or are terminated, surrendered or cancelled without the delivery of shares of Stock, are forfeited
to, or repurchased by, the Company, or otherwise become available again for grant under the Prior Plan, in each case, in accordance with its terms and (ii) on January 1st of each year from
2019 until 2028, by the lesser of (A) four percent (4%) of the number of shares of Stock outstanding as of the close of business on the immediately preceding December 31st and (B) the
number of shares of Stock determined by the Board on or prior to such date for such year (the Initial Share Pool, as it may be so increased, the “Share Pool”). Up to 166,500 of the shares of Stock from the Share Pool may be issued
in satisfaction of ISOs, but nothing in this Section 4(a) will be construed as requiring that any, or any fixed number of, ISOs be granted under the Plan. For purposes of this Section 4(a), shares of Stock will not be treated as issued
under the Plan, and will not reduce the Share Pool, unless and until, and to the extent, the shares are actually issued to a Participant. 

 
Without limiting the generality of the foregoing, shares of Stock withheld by the Company in payment of the exercise price or purchase price of an Award or in satisfaction of tax withholding
requirements with respect to an Award and shares of Stock underlying any portion of an Award that is settled or that expires, becomes unexercisable, terminates or is forfeited to or repurchased by the Company, in each case, without the issuance (or
retention (in the case of Restricted Stock)) of Stock, will not be treated as issued in satisfaction of Awards under the Plan and will not reduce the Share Pool. The limits set forth in this Section 4(a) will be construed to comply with the
applicable requirements of Section 422. 
 (b) Substitute Awards. The Administrator may grant
Substitute Awards under the Plan. To the extent consistent with the requirements of Section 422 and the regulations thereunder and other applicable legal requirements (including applicable stock exchange requirements), shares of Stock issued in
respect of Substitute Awards will be in addition to and will not reduce the Share Pool, but, notwithstanding anything in Section 4(a) to the contrary, if any Substitute Award is settled in cash or expires, becomes unexercisable, terminates or
is forfeited to or repurchased by the Company, in each case, without the issuance (or retention (in the case of restricted stock)) of Stock, the shares of Stock previously subject to such Award will not increase the Share Pool or otherwise be
available for future issuance under the Plan. The Administrator will determine the extent to which the terms and conditions of the Plan apply to Substitute Awards, if at all; provided that Substitute Awards will not be subject to, and will
not count against, the individual limits described in Section 4(d). 
 (c) Type of Shares. The shares of
Stock issued under the Plan may be shares of authorized but unissued Stock, treasury Stock, or Stock acquired in an open-market transaction. No fractional shares of Stock will be issued under the Plan. 

(d) Limits on Director Compensation. The aggregate value of all compensation granted or paid to any Director with
respect to any calendar year, including Awards granted under the Plan and cash fees or other compensation paid by the Company to such Director outside of the Plan, in each case, for his or her services as a Director during such calendar year, may
not exceed $500,000 in the aggregate, calculating the value of any Awards based on the grant date fair value in accordance with the Accounting Rules and assuming maximum payout levels. 

 

	5.	 Eligibility and Participation 

The Administrator will select Participants from among key Employees and Directors of, and consultants and advisors to, the Company and its
subsidiaries. Eligibility for ISOs is limited to employees of the Company or of a “parent corporation” or “subsidiary corporation” of the Company as those terms are defined in Section 424 of the Code. Eligibility for NSOs
and SARs is limited to individuals who are providing direct services on the date of grant of the Award to the Company or to a subsidiary of the Company that would be described in the first sentence of
Section 1.409A-1(b)(5)(iii)(E) of the Treasury Regulations.

	6.	 RULES APPLICABLE TO AWARDS

  

	 	(a)	 All Awards. 

(1) Award Provisions. The Administrator will determine the terms and conditions of all Awards, subject to the
limitations provided herein. By accepting (or, under such rules as the Administrator may prescribe, being deemed to have accepted) an Award, the Participant will be deemed to have agreed to the terms and conditions of the Award and the Plan.
Notwithstanding any provision of the Plan to the contrary, Substitute Awards may contain terms and conditions that are inconsistent with the terms and conditions specified herein, as determined by the Administrator. 

(2) Term of Plan. No Awards may be made after ten years from the Date of Adoption, but previously granted Awards
may continue beyond that date in accordance with their terms. 
 (3) Transferability. Neither ISOs nor, except
as the Administrator otherwise expressly provides in accordance with the third sentence of this Section 6(a)(3), other Awards may be transferred other than by will or by the laws of descent and distribution. During a Participant’s
lifetime, ISOs and, except as the Administrator otherwise expressly provides in accordance with the third sentence of this Section 6(a)(3), SARs and NSOs may be exercised only by the Participant. The Administrator may permit the transfer of
Awards other than ISOs, subject to applicable securities and other laws and such terms and conditions as the Administrator may determine. 

(4) Vesting; Exercisability. The Administrator will determine the time or times at which an Award vests or becomes
exercisable and the terms and conditions on which a Stock Option or SAR remains exercisable. Without limiting the foregoing, the Administrator may at any time accelerate the vesting and/or exercisability of an Award (or any portion thereof),
regardless of any adverse or potentially adverse tax or other consequences resulting from such acceleration. Unless the Administrator expressly provides otherwise, however, the following rules will apply if a Participant’s Employment ceases:

 (A) Except as provided in (B) and (C) below, immediately upon the cessation of the Participant’s
Employment each Stock Option and SAR (or portion thereof) that is then held by the Participant or by the Participant’s permitted transferees, if any, will cease to be exercisable and will terminate, and each other Award that is then held by the
Participant or by the Participant’s permitted transferees, if any, to the extent not then vested, will be forfeited. 

(B) Subject to (C) and (D) below, each vested and unexercised Stock Option and SAR (or portion thereof) held by the
Participant or the Participant’s permitted transferees, if any, immediately prior to the cessation of the Participant’s Employment, to the extent then exercisable, will remain exercisable for the lesser of (i) a period of three months
following such cessation of Employment or (ii) the period ending on the latest date on which such Stock Option or SAR could have been exercised without regard to this Section 6(a)(4), and will thereupon immediately terminate. 

  
 -3- 

 (C) Subject to (D) below, each vested and unexercised Stock
Option and SAR (or portion thereof) held by a Participant or the Participant’s permitted transferees, if any, immediately prior to the cessation of the Participant’s Employment due to his or her death or by the Company as a result of his
or her Disability, to the extent then exercisable, will remain exercisable for the lesser of (i) the one-year period ending on the first anniversary of the Participant’s death or the date on which
the Participant’s Employment is terminated as a result of his or her Disability or (ii) the period ending on the latest date on which such Stock Option or SAR could have been exercised without regard to this Section 6(a)(4), and will
thereupon immediately terminate. 
 (D) All Awards (whether or not vested or exercisable) held by a Participant or the
Participant’s permitted transferees, if any, immediately prior to the cessation of the Participant’s Employment will immediately terminate upon such cessation of Employment if the termination is for Cause or occurs in circumstances that in
the determination of the Administrator would have constituted grounds for the Participant’s Employment to be terminated for Cause (in each case, without regard to the lapsing of any required notice or cure periods in connection therewith). 

(5) Recovery of Compensation. The Administrator may provide in any case that any outstanding Award (whether or not vested
or exercisable), the proceeds from the exercise or disposition of any Award or Stock acquired under any Award, and any other amounts received in respect of any Award or Stock acquired under any Award will be subject to forfeiture and disgorgement to
the Company, with interest and other related earnings, (i) if the Participant to whom the Award was granted is not in compliance with any provision of the Plan or any applicable Award, any
non-competition, non-solicitation, no-hire, non-disparagement, confidentiality, invention
assignment, or other restrictive covenant by which he or she is bound, or any policy of the Company or any of its subsidiaries that is applicable to the Participant and that provides for forfeiture, disgorgement or clawback with respect to incentive
compensation that includes Awards under the Plan; or (ii) to the extent required by law or applicable stock exchange listing standards, including, without limitation, Section 10D of the Securities Exchange Act of 1934, as amended. Each
Participant, by accepting or being deemed to have accepted an Award under the Plan, agrees (or will be deemed to have agreed) to cooperate fully with the Administrator, and to cause any and all permitted transferees of the Participant to cooperate
fully with the Administrator, to effectuate any forfeiture or disgorgement described in this Section 6(a)(5). Neither the Administrator nor the Company nor any other person, other than the Participant and his or her permitted transferees, if
any, will be responsible for any adverse tax or other consequences to a Participant or his or her permitted transferees, if any, that may arise in connection with this Section 6(a)(5). 

(6) Taxes. The issuance, delivery, vesting, and retention of Stock, cash or other property under an Award are
conditioned upon the full satisfaction by the Participant of all tax and other withholding requirements with respect to the Award. The Administrator will prescribe such rules for the withholding of taxes and other amounts with respect to any Award
as it deems necessary. The Administrator may hold back shares of Stock from an Award or permit a Participant to tender previously-owned shares of Stock in satisfaction of tax or other withholding requirements (but not in excess of the maximum
withholding amount consistent with the Award being subject to equity accounting treatment under the Accounting Rules). Any amounts withheld pursuant to this Section 6(a)(6) will be treated as though such payment had been made directly to the
Participant. 

  
 -4- 

 (7) Dividend Equivalents. The Administrator may
provide for the payment of amounts, on such terms and subject to conditions established by the Administrator, in lieu of cash dividends or other cash distributions with respect to Stock subject to an Award, whether or not the holder of such Award is
otherwise entitled to share in the actual dividend or distribution in respect of such Award. Subject to Section 6(a)(10), any entitlement to dividend equivalents or similar entitlements will be established and administered either consistent
with an exemption from, or in compliance with, the applicable requirements of Section 409A. Dividends and dividend equivalent amounts payable in respect of Awards that are subject to restrictions may be subject to such limitations or
restrictions as the Administrator may impose. 
 (8) Rights Limited. Nothing in the Plan or any Award will be
construed as giving any person the right to be granted an Award or to continued employment or service with the Company or any of its subsidiaries, or any rights as a stockholder except as to shares of Stock actually issued under the Plan. The loss
of existing or potential profit in any Award will not constitute an element of damages in the event of a termination of a Participant’s Employment for any reason, even if the termination is in violation of an obligation of the Company or any of
its subsidiaries to the Participant. 
 (9) Coordination with Other Plans. Awards under the Plan may be granted
in tandem with, or in satisfaction of or substitution for, other Awards under the Plan or awards made under other compensatory plans or programs of the Company or any of its subsidiaries. For example, but without limiting the generality of the
foregoing, awards under other compensatory plans or programs of the Company or any of its subsidiaries may be settled in shares of Stock (including, without limitation, Unrestricted Stock) under the Plan if the Administrator so determines, in which
case the shares will be treated as issued under the Plan (and will reduce the Share Pool in accordance with the rules set forth in Section 4). 

(10) Section 409A. 

(A) Without limiting the generality of Section 11(b), each Award will contain such terms as the Administrator
determines and will be construed and administered such that the Award either qualifies for an exemption from the requirements of Section 409A or satisfies such requirements. 

(B) If a Participant is determined on the date of the Participant’s termination of Employment to be a
“specified employee” within the meaning of that term under Section 409A(a)(2)(B) of the Code, then, with regard to any payment that is considered nonqualified deferred compensation under Section 409A, to the extent applicable,
payable on account of a “separation from service”, such payment will be made or provided on the date that is the earlier of (i) the first business day following the expiration of the six-month
period measured from the date of such “separation from service” and (ii) the date of the Participant’s death (the “Delay Period”). Upon the expiration of the Delay Period, all payments delayed pursuant to this
Section 6(a)(10)(B) (whether they would have otherwise been payable in a single lump sum or in installments in the absence of such delay) will be paid on the first business day following the expiration of the Delay Period in a lump sum and any
remaining payments due under the Award will be paid in accordance with the normal payment dates specified for them in the applicable Award agreement. 

  
 -5- 

 (C) With regard to any payment considered to be nonqualified deferred
compensation under Section 409A, to the extent applicable, that is payable upon a change in control of the Company or other similar event, to the extent required to avoid the imposition of any additional tax, interest, or penalty under
Section 409A, no amount will be payable unless such change in control constitutes a “change in control event” within the meaning of Section 1.409A-3(i)(5) of the Treasury Regulations. 

(D) For purposes of Section 409A, each payment made under the Plan will be treated as a separate payment. 

(b) Stock Options and SARs. 

(1) Time and Manner of Exercise. Unless the Administrator expressly provides otherwise, no Stock Option or SAR
will be considered to have been exercised until the Administrator receives a notice of exercise in a form acceptable to the Administrator that is signed by the appropriate person and accompanied by any payment required under the Award. Any attempt
to exercise a Stock Option or SAR by any person other than the Participant will not be given effect unless the Administrator has received such evidence as it may require that the person exercising the Award has the right to do so. 

(2) Exercise Price. The exercise price (or the base value from which appreciation is to be measured) of each Award
requiring exercise must be no less than 100% (in the case of an ISO granted to a 10-percent stockholder within the meaning of Section 422(b)(6) of the Code, 110%) of the Fair Market Value of a share of
Stock, determined as of the date of grant, or such higher amount as the Administrator may determine in connection with the grant. 

(3) Payment of Exercise Price. Where the exercise of an Award (or portion thereof) is to be accompanied by a
payment, payment of the exercise price must be made by cash or check acceptable to the Administrator or, if so permitted by the Administrator and if legally permissible, (i) through the delivery of previously acquired unrestricted shares of
Stock, or the withholding of unrestricted shares of Stock otherwise issuable upon exercise, in either case, that have a Fair Market Value equal to the exercise price; (ii) through a broker-assisted exercise program acceptable to the
Administrator; (iii) by other means acceptable to the Administrator; or (iv) by any combination of the foregoing permissible forms of payment. The delivery of previously acquired shares in payment of the exercise price under clause
(i) above may be accomplished either by actual delivery or by constructive delivery through attestation of ownership, subject to such rules as the Administrator may prescribe. 

(4) Maximum Term. The maximum term of Stock Options and SARs must not exceed 10 years from the date of grant (or
five years from the date of grant in the case of an ISO granted to a 10-percent stockholder described in Section 6(b)(2)). 

  
 -6- 

 (5) Repricing. Except in connection with a corporate transaction
involving the Company (which term includes, without limitation, any stock dividend, stock split, extraordinary cash dividend, recapitalization, reorganization, merger, consolidation, split up, spin-off,
combination or exchange of shares) or as otherwise contemplated by Section 7 below, The Company may not, without obtaining stockholder approval, (i) amend the terms of outstanding Stock Options or SARs to reduce the exercise price or base
value of such Stock Options or SARs; (ii) cancel outstanding Stock Options or SARs in exchange for Stock Options or SARs with an exercise price or base value that is less than the exercise price or base value of the original Stock Options or
SARs; or (iii) cancel outstanding Stock Options or SARs that have an exercise price or base value greater than the Fair Market Value of a share of Stock on the date of such cancellation in exchange for cash or other consideration. 

 

	7.	 EFFECT OF CERTAIN TRANSACTIONS

 (a) Covered Transactions. Except as otherwise expressly provided in an
Award agreement or by the Administrator, the following provisions will apply in the event of a Covered Transaction: 
 (1)
Assumption or Substitution. If the Covered Transaction is one in which there is an acquiring or surviving entity, the Administrator may provide for (i) the assumption or continuation of some or all outstanding Awards or any
portion thereof or (ii) the grant of new awards in substitution therefor by the acquiror or survivor or an affiliate of the acquiror or survivor. 

(2) Cash-Out of Awards. Subject to Section 7(a)(5), the Administrator
may provide for payment (a “cash-out”), with respect to some or all Awards or any portion thereof (including only the vested portion thereof), equal in the case of each applicable Award or
portion thereof to the excess, if any, of (i) the Fair Market Value of a share of Stock multiplied by the number of shares of Stock subject to the Award or such portion, minus (ii) the aggregate exercise or purchase price, if any, of such
Award or portion (or, in the case of a SAR, the aggregate base value above which appreciation is measured), in each case, on such payment and other terms and subject to such conditions (which need not be the same as the terms and conditions
applicable to holders of Stock generally ) as the Administrator determines, including that any amounts paid in respect of such Award in connection with the Covered Transaction be placed in escrow or otherwise made subject to such restrictions as the
Administrator deems appropriate. For the avoidance of doubt, if the per share exercise or purchase price (or base value) of an Award or portion thereof is equal to or greater than the Fair Market Value of one share of Stock, such Award or portion
may be cancelled with no payment due hereunder or otherwise in respect thereof. 
 (3) Acceleration of Certain
Awards. Subject to Section 7(a)(5), the Administrator may provide that any Award requiring exercise will become exercisable, in full or in part, and/or that the issuance of any shares of Stock remaining issuable under any
outstanding Award of Stock Units (including Restricted Stock Units and Performance Awards to the extent consisting of Stock Units) will be accelerated, in full or in part, in each case, on a basis that gives the holder of the Award a reasonable
opportunity, as determined by the Administrator, following the exercise of the Award or the issuance of the shares, as the case may be, to participate as a stockholder in the Covered Transaction. 

  
 -7- 

 (4) Termination of Awards upon Consummation of Covered Transaction.
Except as the Administrator may otherwise determine, each Award will automatically terminate (and in the case of outstanding shares of Restricted Stock, will automatically be forfeited) immediately upon the consummation of the Covered
Transaction, other than (i) any Award that is assumed, continued or substituted for pursuant to Section 7(a)(1) and (ii) any Award that by its terms, or as a result of action taken by the Administrator, continues following the Covered
Transaction. 
 (5) Additional Limitations. Any share of Stock and any cash or other property delivered pursuant
to Section 7(a)(2) or Section 7(a)(3) with respect to an Award may, in the discretion of the Administrator, contain such limitations or restrictions, if any, as the Administrator deems appropriate, including to reflect any performance or
other vesting conditions to which the Award was subject and that did not lapse (and were not satisfied) in connection with the Covered Transaction. For purposes of the immediately preceding sentence, a
cash-out under Section 7(a)(2) or an acceleration under Section 7(a)(3) will not, in and of itself, be treated as the lapsing (or satisfaction) of a performance or other vesting condition. In the
case of Restricted Stock that does not vest and is not forfeited in connection with the Covered Transaction, the Administrator may require that any amounts delivered, exchanged or otherwise paid in respect of such Stock in connection with the
Covered Transaction be placed in escrow or otherwise made subject to such restrictions as the Administrator deems appropriate to carry out the intent of the Plan. 

(6) Uniform Treatment. For the avoidance of doubt, the Administrator need not treat Participants or Awards (or
portions thereof) in a uniform matter, and may treat different Participants and/or Awards differently, in connection with a Covered Transaction. 

(b) Changes in and Distributions with Respect to Stock. 

(1) Basic Adjustment Provisions. In the event of a stock dividend, stock split or combination of shares (including
a reverse stock split), recapitalization or other change in the Company’s capital structure that constitutes an equity restructuring within the meaning of the Accounting Rules, the Administrator will make appropriate adjustments to the maximum
number of shares of Stock specified in Section 4(a) that may be issued under the Plan, the number and kind of shares of stock or securities underlying Awards then outstanding or subsequently granted, any exercise or purchase prices (or base
values) relating to Awards and any other provision of Awards affected by such change. 
 (2) Certain Other
Adjustments. The Administrator may also make adjustments of the type described in Section 7(b)(1) to take into account distributions to stockholders other than those provided for in Section 7(a) and 7(b)(1), or any other
event, if the Administrator determines that adjustments are appropriate to avoid distortion in the operation of the Plan or any Award. 

(3) Continuing Application of Plan Terms. References in the Plan to shares of Stock will be construed to include
any stock or securities resulting from an adjustment pursuant to this Section 7. 

  
 -8- 

	8.	 LEGAL CONDITIONS ON THE ISSUANCE
OF STOCK 

 The Company will not be obligated to issue any shares of Stock pursuant to
the Plan or to remove any restriction from shares of Stock previously issued under the Plan until: (i) the Company is satisfied that all legal matters in connection with the issuance of such shares have been addressed and resolved; (ii) if
the outstanding Stock is at the time of issuance listed on any stock exchange or national market system, the shares to be issued have been listed or authorized to be listed on such exchange or system upon official notice of issuance; and
(iii) all conditions of the Award have been satisfied or waived. The Company may require, as a condition to the exercise of an Award or the issuance of shares of Stock under an Award, such representations or agreements as counsel for the
Company may consider appropriate to avoid violation of the Securities Act of 1933, as amended, or any applicable state or non-U.S. securities law. Any Stock issued under the Plan will be evidenced in such
manner as the Administrator determines appropriate, including book-entry registration or delivery of stock certificates. In the event that the Administrator determines that stock certificates will be issued in connection with Stock issued under the
Plan, the Administrator may require that such certificates bear an appropriate legend reflecting any restriction on transfer applicable to such Stock, and the Company may hold the certificates pending the lapse of the applicable restrictions. 

 

	9.	 AMENDMENT AND TERMINATION 

The Administrator may at any time or times amend the Plan or any outstanding Award for any purpose which may at the time be permitted by
applicable law, and may at any time terminate the Plan as to any future grants of Awards; provided that, except as otherwise expressly provided in the Plan or the applicable Award, the Administrator may not, without the Participant’s
consent, alter the terms of an Award so as to materially and adversely affect the Participant’s rights under the Award, unless the Administrator expressly reserved the right to do in the Plan or at the time the applicable Award was granted. Any
amendments to the Plan will be conditioned upon stockholder approval only to the extent, if any, such approval is required by applicable law (including the Code) or stock exchange requirements, as determined by the Administrator. For the avoidance
of doubt, no adjustment to any Award pursuant to the terms of Section 7 will be treated as an amendment requiring a Participant’s consent. 
  

	10.	 OTHER COMPENSATION ARRANGEMENTS 

The existence of the Plan or the grant of any Award will not affect the right of the Company or any of its subsidiaries to grant any person
bonuses or other compensation in addition to Awards under the Plan. 
  

	11.	 MISCELLANEOUS 

(a) Waiver of Jury Trial. By accepting or being deemed to have accepted an Award under the Plan, each Participant
waives (or will be deemed to have waived), to the maximum extent permitted under applicable law, any right to a trial by jury in any action, proceeding or counterclaim concerning any rights under the Plan or any Award, or under any amendment,
waiver, consent, instrument, document or other agreement delivered or which in the future may be delivered in connection therewith, and agrees (or will be deemed to have agreed) that any 

  
 -9- 

 
such action, proceedings or counterclaim will be tried before a court and not before a jury. By accepting or being deemed to have accepted an Award under the Plan, each Participant certifies that
no officer, representative, or attorney of the Company has represented, expressly or otherwise, that the Company would not, in the event of any action, proceeding, or counterclaim, seek to enforce the foregoing waivers. Notwithstanding anything to
the contrary in the Plan, nothing herein is to be construed as limiting the ability of the Company and a Participant to agree to submit any dispute arising under the terms of the Plan or any Award to binding arbitration or as limiting the ability of
the Company to require any individual to agree to submit such disputes to binding arbitration as a condition of receiving an Award hereunder. 

(b) Limitation of Liability. Notwithstanding anything to the contrary in the Plan or any Award, neither the
Company, nor any of its subsidiaries, nor the Administrator, nor any person acting on behalf of the Company, any of its subsidiaries, or the Administrator, will be liable to any Participant, to any permitted transferee, to the estate or beneficiary
of any Participant or any permitted transferee, or to any other person by reason of any acceleration of income, any additional tax, or any penalty, interest or other liability asserted by reason of the failure of an Award to satisfy the requirements
of Section 422 or Section 409A, by reason of Section 4999 of the Code, or otherwise asserted with respect to any Award. 

(c) Unfunded Plan. The Company’s obligations under the Plan are unfunded, and no Participant will have any
right to specific assets of the Company in respect of any Award. Participants will be general unsecured creditors of the Company with respect to any amounts due or payable under the Plan. 

(d) Section 162(m). To the extent applicable, Awards granted pursuant to the Plan are intended to be eligible for
exemption from the limitations of Section 162(m) of the Code by reason of the post-initial public offering transition relief set forth in Section 1.162-27(f) of the Treasury Regulations. 

 

	12.	 ESTABLISHMENT OF
SUB-PLANS 

 The Administrator may at any time
and from time to time establish one or more sub-plans under the Plan (for local law compliance purposes or other purposes or administrative reasons determined by the Administrator) by adopting supplements to
the Plan containing, in each case, (i) such limitations on the Administrator’s discretion under the Plan and (ii) such additional terms and conditions, as the Administrator deems necessary or desirable. Each supplement so established
will be deemed to be part of the Plan but will apply only to Participants within the group to which the supplement applies (as determined by the Administrator). 
  

	13.	 GOVERNING LAW 

(a) Certain Requirements of Corporate Law. Awards and shares of Stock will be granted, issued and administered
consistent with the requirements of applicable Delaware law relating to the issuance of stock and the consideration to be received therefor, and with the applicable requirements of the stock exchanges or other trading systems on which the Stock is
listed or entered for trading, in each case, as determined by the Administrator. 

  
 -10- 

 (b) Other Matters. Except as otherwise provided by the express
terms of an Award agreement, under a sub-plan described in Section 12 or as provided in Section 13(a), the domestic substantive laws of the State of New Hampshire govern the provisions of the Plan
and of Awards under the Plan and all claims or disputes arising out of or based upon the Plan or any Award under the Plan or relating to the subject matter hereof or thereof, without giving effect to any choice or conflict of laws provision or rule
that would cause the application of the domestic substantive laws of any other jurisdiction. 
 (c) Jurisdiction.
By accepting (or being deemed to have accepted) an Award, each Participant agrees or will be deemed to have agreed to (i) submit irrevocably and unconditionally to the jurisdiction of the federal and state courts located within the
geographic boundaries of the United States District Court for the District of New Hampshire for the purpose of any suit, action or other proceeding arising out of or based upon the Plan or any Award; (ii) not commence any suit, action or other
proceeding arising out of or based upon the Plan or any Award, except in the federal and state courts located within the geographic boundaries of the United States District Court for the District of New Hampshire; and (iii) waive, and not
assert, by way of motion as a defense or otherwise, in any such suit, action or proceeding, any claim that he or she is not subject personally to the jurisdiction of the above-named courts that his or her property is exempt or immune from attachment
or execution, that the suit, action or proceeding is brought in an inconvenient forum, that the venue of the suit, action or proceeding is improper or that the Plan or any Award or the subject matter thereof may not be enforced in or by such court.

(ii) the consummation of the merger or consolidation of the Company with any other company, other than (a) a merger or consolidation

persons and/or entities acting in concert; (ii) a sale or transfer of all or substantially all the Company’s assets; (iii) a Change in Control; or (iv) a dissolution or liquidation of the Company. Where a Covered Transaction

Participant’s employment or other service relationship is with any subsidiary of the Company and that entity ceases to be a subsidiary of the Company, the Participant’s Employment will be deemed to have terminated when the entity ceases to
be a subsidiary of the Company unless the Participant transfers Employment to the Company or one of its remaining subsidiaries. Notwithstanding the foregoing, in construing the provisions of any Award relating to the payment of “nonqualified
deferred compensation” (subject to Section 409A) upon a termination or cessation of Employment, references to termination or cessation of employment, separation from service, retirement or similar or correlative terms will be construed to
require a “separation from service” (as that term is defined in Section 1.409A-1(h) of the Treasury Regulations) from

the Company and from all other corporations and trades or businesses, if any, that would be treated as a single “service recipient” with the Company under
Section 1.409A-1(h)(3) of the Treasury Regulations. The Company may, but need not, elect in writing, subject to the applicable limitations under Section 409A, any of the special elective rules

 Exhibit 10.19 

VAPOTHERM, INC. 

2018 CASH INCENTIVE PLAN 

 

	1.	 DEFINED TERMS 

Exhibit A, which is incorporated by reference, defines certain terms used in the Plan and sets forth operational rules related to those
terms. 
  

	2.	 PURPOSE 

The Plan is intended to advance the interests of the Company by providing for the grant of cash-based incentive Awards to executive officers
and key employees of the Company and its subsidiaries. The purposes of the Plan are to attract, retain, and reward executive officers and key employees of the Company and its subsidiaries, to incentivize them to generate shareholder value, and to
enable them to participate in the growth of the Company. 
  

	3.	 ADMINISTRATION 

The Plan will be administered by the Administrator. The Administrator has discretionary authority, subject only to the express provisions of
the Plan, to administer and interpret the Plan and any Award; to determine eligibility for and grant Awards; to adjust the performance criterion or criteria applicable to Awards; to determine, modify or waive the terms and conditions of any Award;
to prescribe forms, rules and procedures relating to the Plan and Awards; and to otherwise do all things necessary or desirable to carry out the purposes of the Plan or any Award. Determinations of the Administrator made with respect to the Plan or
any Award are conclusive and bind all persons. 
  

	4.	 ELIGIBILITY; PARTICIPATION 

The Administrator may select Participants from among executive officers and key employees of the Company and its subsidiaries. 

 

	5.	 GRANT OF AWARDS 

A Participant who is granted an Award will be entitled to a payment, if any, in respect of the Award only if all conditions to payment have
been satisfied in accordance with the Plan and the terms of the Award. By accepting (or being deemed to have accepted) an Award, the Participant agrees or will be deemed to have agreed to the terms and condition of the Award and the Plan. The
Administrator will select the Participants, if any, who receive Awards for each Performance Period and, for each Award, will establish the following: 

(a) the Performance Criterion or Criteria applicable to the Award; 

(b) the amount or amounts that will be payable (subject to adjustment in accordance with Section 6) if the performance criterion
or criteria are achieved in whole or in part; and 
 (c) such other terms and conditions as the Administrator determines with respect
to the Award. 

	6.	 DETERMINATION OF PERFORMANCE; AMOUNTS
PAYABLE UNDER AWARDS 

 As soon as practicable after the end of the
applicable Performance Period, the Administrator will determine whether and to what extent, if at all, the performance criterion or criteria applicable to each Award granted for such Performance Period have been satisfied. The Administrator will
then determine the amount payable, if any, under each Award. The Administrator may, in its sole discretion and with or without specifying its reasons for doing so, after determining the amount that would otherwise be payable in respect of any Award,
adjust the actual payment, if any, to be made with respect to such Award. The Administrator may exercise the discretion described in the immediately preceding sentence either in individual cases or in ways that affect more than one Participant. In
each case, the Administrator’s discretionary determination, which may affect different Awards differently, are conclusive and bind all persons. 
  

	7.	 PAYMENTS UNDER AWARDS 

The Administrator will determine the payment dates for Awards under the Plan. Except as otherwise determined by the Administrator: 

(a) all payments under the Plan will be made, if at all, not later than March 15th
of the calendar year immediately following the calendar year in which the Performance Period ends; provided, that the Administrator may authorize elective deferrals of any Award payments in accordance with the deferral rules of
Section 409A; 
 (b) payment will not be made with respect to an Award unless the Participant has remained employed with the
Company and its subsidiaries through the date of payment; and 
 (c) awards under the Plan are intended to qualify for exemption from
Section 409A of the Code and shall be construed and administered accordingly. 
  

	8.	 PAYMENT LIMITS 

The maximum amount paid to any Participant in any calendar year pursuant to Awards granted under the Plan will be $2,500,000, which limitation
will be applied without regard to any elective deferral described in Section 7(a). 
  

	9.	 TAX WITHHOLDING; LIMITATION ON
LIABILITY 

 All payments under the Plan will be reduced by all tax and other amounts required to be
withheld with respect to the payment. Any amounts withheld pursuant to this Section 9 will be treated as though such payment had been made directly to the Participant. 
  

	10.	 AMENDMENT AND TERMINATION 

The Administrator may at any time or times amend the Plan or any outstanding Award for any purpose which may at the time be permitted by
applicable law, and may at any time terminate the Plan as to any future grants of Awards. For the avoidance of doubt, no adjustment to any Award pursuant to the terms of Section 6 will be treated as an amendment requiring a Participant’s
consent. 

  
 -2- 

	11.	 RECOVERY OF COMPENSATION 

The Administrator may provide in any case that any outstanding Award and any amounts received in respect of any Award will be subject to
forfeiture and disgorgement to the Company, with interest and other related earnings, (i) if the Participant to whom the Award was granted is not in compliance with any provision of the Plan or any applicable Award, any non-competition, non-solicitation, no-hire, non-disparagement, confidentiality, invention
assignment, or other restrictive covenant by which he or she is bound, or any policy of the Company or any of its subsidiaries that is applicable to the Participant and that provides for forfeiture, disgorgement or clawback with respect to incentive
compensation that includes Awards under the Plan; or (ii) to the extent required by law or applicable stock exchange listing standards, including, without limitation, Section 10D of the Securities Exchange Act of 1934, as amended. Each
Participant, by accepting (or being deemed to have accepted) an Award under the Plan, agrees or will be deemed to have agreed to cooperate fully with the Administrator to effectuate any forfeiture or disgorgement described in this Section 11.
Neither the Administrator nor the Company nor any other person, other than the Participant, will be responsible for any adverse tax or other consequences to a Participant that may arise in connection with this Section 11. 

 

	12.	 MISCELLANEOUS 

(a) Waiver of Jury Trial. By accepting or being deemed to have accepted an Award under the Plan, each Participant
waives (or will be deemed to have waived), to the maximum extent permitted under applicable law, any right to a trial by jury in any action, proceeding or counterclaim concerning any rights under the Plan or any Award, or under any amendment,
waiver, consent, instrument, document or other agreement delivered or which in the future may be delivered in connection therewith, and agrees (or will be deemed to have agreed) that any such action, proceedings or counterclaim will be tried before
a court and not before a jury. By accepting or being deemed to have accepted an Award under the Plan, each Participant certifies that no officer, representative, or attorney of the Company has represented, expressly or otherwise, that the Company
would not, in the event of any action, proceeding, or counterclaim, seek to enforce the foregoing waivers. Notwithstanding anything to the contrary in the Plan, nothing herein is to be construed as limiting the ability of the Company and a
Participant to agree to submit any dispute arising under the terms of the Plan or any Award to binding arbitration or as limiting the ability of the Company to require any individual to agree to submit such disputes to binding arbitration as a
condition of receiving an Award hereunder. 
 (b) Limitation of Liability. Notwithstanding anything to the
contrary in the Plan or any Award, neither the Company, nor any of its subsidiaries, nor the Administrator, nor any person acting on behalf of the Company, any of its subsidiaries, or the Administrator, will be liable to any Participant or to any
other person by reason of any acceleration of income, any additional tax, or any penalty, interest or other liability asserted by reason of the failure of an Award to satisfy the requirements of Section 409A or by reason of Section 4999 of
the Code, or otherwise asserted with respect to any Award. 
 (c) Unfunded Plan. The Company’s obligations
under the Plan are unfunded, and no Participant will have any right to specific assets of the Company in respect of any Award. Participants will be general unsecured creditors of the Company with respect to any amounts due or payable under the Plan.

  
 -3- 

 (d) Governing Law. Except as otherwise provided by the express
terms of an Award, the domestic substantive laws of the State of New Hampshire govern the provisions of the Plan and of Awards under the Plan and all claims or disputes arising out of or based upon the Plan or any Award under the Plan or relating to
the subject matter hereof or thereof, without giving effect to any choice or conflict of laws provision or rule that would cause the application of the domestic substantive laws of any other jurisdiction. 

(e) Jurisdiction. By accepting (or being deemed to have accepted) an Award, each Participant agrees or will be
deemed to have agreed to (i) submit irrevocably and unconditionally to the jurisdiction of the federal and state courts located within the geographic boundaries of the United States District Court for the District of New Hampshire for the
purpose of any suit, action or other proceeding arising out of or based upon the Plan or any Award; (ii) not commence any suit, action or other proceeding arising out of or based upon the Plan or any Award, except in the federal and state
courts located within the geographic boundaries of the United States District Court for the District of New Hampshire; and (iii) waive, and not assert, by way of motion as a defense or otherwise, in any such suit, action or proceeding, any
claim that he or she is not subject personally to the jurisdiction of the above-named courts that his or her property is exempt or immune from attachment or execution, that the suit, action or proceeding is brought in an inconvenient forum, that the
venue of the suit, action or proceeding is improper or that the Plan or any Award or the subject matter thereof may not be enforced in or by such court.  

(f) Other Compensation Arrangements. The existence of the Plan or the grant of any Award will not affect the right
of the Company or any of its subsidiaries to grant any person bonuses or other compensation in addition to Awards under the Plan. 

(g) Rights Limited. Nothing in the Plan or any Award will be construed as giving any person the right to be
granted an Award or to continued employment or service with the Company or any of its subsidiaries. The loss of any Award will not constitute an element of damages in the event of a termination of a Participant’s employment for any reason, even
if the termination is in violation of an obligation of the Company or any of its subsidiaries to the Participant. 
 (h)
Section 162(m). To the extent applicable, Awards granted pursuant to the Plan are intended to be eligible for exemption from the limitations of Section 162(m) of the Code by reason of the post-initial public offering
transition relief set forth in Section 1.162-27(f) of the Treasury Regulations. 
 (i)
Effective Date. The Plan will be effective upon adoption of the Plan by the Administrator and will supersede and replace the Company’s annual cash bonus program with respect to awards granted to eligible executive officers
and employees for fiscal years beginning after the date of adoption.
