EXPLANATORY NOTE



This Amendment No. 1 (this “Amendment”)
amends the Annual Report on Form 10-K for the year ended December 31, 2019 of TFF Pharmaceuticals, Inc., filed with the Securities
and Exchange Commission (the “SEC”) on March 27, 2020 (the “Original Form 10-K”). The purpose of this
Amendment is to amend Part III, Items 10 through 14 of the Original Form 10-K to include information previously omitted from the
Original Form 10-K in reliance on General Instruction G(3) to Form 10-K.  Accordingly, Part III of the Original Form 10-K
is hereby amended and restated as set forth below and the reference on the cover page of the Original Form 10-K to the incorporation
by reference of our definitive proxy statement into Part III of the Original Form 10-K is hereby deleted.



In addition, as required by Rule 12b-15 under
the Securities Exchange Act of 1934, as amended (the “Exchange Act”) new certifications by our principal executive
officer and principal financial officer are filed as exhibits to this Amendment under Item 15 of Part IV hereof, which has been
amended to reflect the filing of these new certifications. Because no financial statements have been included in this Amendment
and this Amendment does not contain or amend any disclosure with respect to Items 307 and 308 of Regulation S-K, paragraphs 3,
4, and 5 of the certifications have been omitted.



Except as described above, no other changes
have been made to the Original Form 10-K. The Original Form 10-K continues to speak as of the date of the Original Form 10-K, and
we have not updated the disclosures contained therein to reflect any events which occurred at a date subsequent to the filing of
the Original Form 10-K other than as expressly indicated in this Amendment. In this Amendment, unless the context indicates otherwise,
the terms “Company,” “we,” “us,” and “our” refer to TFF Pharmaceuticals, Inc. Other
defined terms used in this Amendment but not defined herein shall have the meaning specified for such terms in the Original Form
10-K.



CAUTIONARY NOTICE

All statements in this Amendment
that are not historical are forward-looking statements within the meaning of Section 21E of the Exchange Act. These forward-looking
statements can generally be identified as such because the context of the statement will include words such as “may,”
“will,” “intend,” “plans,” “believes,” “anticipates,” “expects,”
“estimates,” “predicts,” “potential,” “continue,” “opportunity,” “goals,”
or “should,” the negative of these words or words of similar import. Similarly, statements that describe our future
plans, strategies, intentions, expectations, objectives, goals or prospects are also forward-looking statements. These forward-looking
statements are or will be, as applicable, based largely on our expectations and projections about future events and future trends
affecting our business, and so are or will be, as applicable, subject to risks and uncertainties including but not limited to the
risk factors discussed in the Original Form 10-K, that could cause actual results to differ materially from those anticipated in
the forward-looking statements. We caution investors that there can be no assurance that actual results or business conditions
will not differ materially from those projected or suggested in such forward-looking statements. Our views and the events, conditions
and circumstances on which these future forward-looking statements are based, may change.

Corporate Governance

Audit Committee

Our Audit Committee
consists of Randy Thurman, Stephen Rocamboli and Malcolm Fairbairn, with Mr. Thurman serving as Chairperson. The composition
of our Audit Committee meets the requirements for independence under current Nasdaq Stock Market listing standards and SEC rules
and regulations. Each member of our Audit Committee meets the financial literacy requirements of the Nasdaq Stock Market listing
standards. Mr. Thurman is an audit committee financial expert within the meaning of Item 407(d) of Regulation S-K under the
Securities Act of 1933, as amended, or the Securities Act.

Process for
Stockholders to Send Communications to our Board of Directors

Because we have
always maintained open channels of communication with our stockholders, we do not have a formal policy that provides a process
for stockholders to send communications to our Board. However, if a stockholder would like to send a communication to our Board,
please address the letter to the attention of our corporate secretary, Kirk Coleman, and it will be distributed to each director.

Compensation
Committee Interlocks and Insider Participation

None of our independent
directors, Aaron Fletcher, Ph.D., Robert S. Mills, Stephen C. Rocamboli, Harlan Weisman, M.D., Randy Thurman or Malcolm Fairbairn,
is currently or has been at any time one of our officers or employees, except for Mr. Mills’ service as an interim executive
officer from January 2018 to December 2018. None of our executive officers currently serves, or has served during the last year,
as a member of the board or compensation committee of any entity that has one or more executive officers serving as a member of
our Board.

Section 16(A)
Beneficial Ownership Reporting Compliance

Rules adopted by
the SEC under Section 16(a) of the Exchange Act require our officers and directors, and persons who own more than 10% of the issued
and outstanding shares of our equity securities, to file reports of their ownership, and changes in ownership, of such securities
with the SEC on Forms 3, 4 or 5, as appropriate. Such persons are required by the regulations of the SEC to furnish us with copies
of all forms they file pursuant to Section 16(a).

Based solely upon
a review of Forms 3, 4 and 5 and amendments thereto furnished to us during our most recent fiscal year, and any written representations
provided to us, we believe that all of the officers, directors, and owners of more than 10% of the outstanding shares of our common
stock complied with Section 16(a) of the Exchange Act for the year ended December 31, 2019.

Code of Conduct

We have adopted
a code of conduct for all employees, including the chief executive officer, principal financial officer and principal accounting
officer or controller, and/or persons performing similar functions, which is available on our website, under the link http://ir.tffpharma.com/corporate-governance.

Limitation of
Liability of Directors and Indemnification of Directors and Officers

The Delaware General
Corporation Law provides that corporations may include a provision in their certificate of incorporation relieving directors of
monetary liability for breach of their fiduciary duty as directors, provided that such provision shall not eliminate or limit
the liability of a director (i) for any breach of the director’s duty of loyalty to the corporation or its stockholders,
(ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) for
unlawful payment of a dividend or unlawful stock purchase or redemption, or (iv) for any transaction from which the director derived
an improper personal benefit. Our certificate of incorporation provides that directors are not liable to us or our stockholders
for monetary damages for breach of their fiduciary duty as directors to the fullest extent permitted by Delaware law. In addition
to the foregoing, our certificate of incorporation provides that we shall indemnify directors, officers, employees or agents to
the fullest extent permitted by law and we have agreed to provide such indemnification to each of our executive officers and directors
by way of written indemnification agreements.

The above provisions
in our certificate of incorporation and bylaws and in the written indemnity agreements may have the effect of reducing the likelihood
of derivative litigation against directors and may discourage or deter stockholders or management from bringing a lawsuit against
directors for breach of their fiduciary duty, even though such an action, if successful, might otherwise have benefited us and
our stockholders. However, we believe that the foregoing provisions are necessary to attract and retain qualified persons as directors.

Insofar as indemnification
for liabilities arising under the Securities Act may be permitted to our directors, officers and controlling persons pursuant to
the foregoing provisions, or otherwise, we have been advised that in the opinion of the SEC, such indemnification is against public
policy as expressed in the Securities Act and is, therefore, unenforceable.

Compensation of Directors

as a chairman of any committee of the Board. Mr. Rocamboli has declined to accept any cash fees for his service on our Board. We
also reimburse our independent directors for their reasonable expenses incurred in connection with attending meetings of our Board.

to unexercisable options, 25% of the option award vests and first becomes exercisable on the first anniversary of the date of grant,
with the remaining 75% of the option award vesting in 12 equal quarterly installments thereafter.

Inc. 2018 Stock Incentive Plan, or the Plan, was originally adopted on January 24, 2018 and, at that time, we initially reserved
1,630,000 shares of our common stock under the Plan. However, upon completion of our initial public offering in October 2019,
the number of shares reserved for issuance under the Plan increased to 3,284,480, representing 15% of our outstanding shares of
our common stock calculated on a fully-diluted basis upon the close of our initial public offering. As of April 22, 2020, we have
issued options to purchase 1,018,147 shares of common stock under the Plan.

| | Item 12. | Security Ownership of Certain Beneficial Owners and Management and Related Stockholder Matters
| | -------- | ----------------------------------------------------------------------------------------------

The following table
sets forth certain information regarding the beneficial ownership of our common stock as of April 22, 2020 by:

| | · | each person who is known by us to be the beneficial owner of more than five percent (5%) of our issued and outstanding shares of common stock;
| | - | ----------------------------------------------------------------------------------------------------------------------------------------------
| | · | each of our directors, director nominees and executive officers; and                                                                          
| | · | all directors, director nominees and executive officers as a group.                                                                           



The beneficial ownership
of each person was calculated based on 18,671,657 common shares issued and outstanding as of April 22, 2020. The SEC has defined
“beneficial ownership” to mean more than ownership in the usual sense. For example, a person has beneficial ownership
of a share not only if he owns it, but also if he has the power (solely or shared) to vote, sell or otherwise dispose of the share.
Beneficial ownership also includes the number of shares that a person has the right to acquire within 60 days, pursuant to the
exercise of options or warrants or the conversion of notes, debentures or other indebtedness. Two or more persons might count as
beneficial owners of the same share. Unless otherwise indicated, the address for each reporting person is 2600 Via Fortuna, Suite
360, Austin, Texas 78701.

| | Item 13. | Certain Relationships and Related Transactions, and Director Independence
| | -------- | -------------------------------------------------------------------------

Related Party Transactions

Since January 1,
2018, we have not entered into any transactions where the amount exceeded the lesser of $120,000 or one percent (1%) of the average
of our total assets as of December 31, 2019 and 2018 with any of our directors, officers, beneficial owners of five percent or
more of our common shares, any immediate family members of the foregoing or entities of which any of the foregoing are also officers
or directors or in which they have a material financial interest, other than the compensatory arrangements with our executive officers
and directors described elsewhere in this Report and as described below.

We were incorporated
under the laws of the state of Delaware on January 24, 2018 by Lung Therapeutics, Inc., or LTI. In March 2018, we completed a Series
A preferred stock financing with third-party investors, at which time we acquired certain of LTI’s non-core intellectual
property rights and other assets all of which related to our TFF platform, in exchange for 4,000,000 shares of our common stock,
which had a deemed value at the time of $10 million based on the $2.50 per share price of our Series A preferred stock. LTI is
an early-stage company focused on the development of certain technologies in the pulmonary field. LTI currently provides us with
office space and certain administrative services and equipment for no charge, from time to time on an as-needed basis, and three
of our directors, Aaron Fletcher, Ph.D., Robert Mills and Brian Windsor, Ph.D., are members of the board of directors of LTI.

Except as set forth
above, we have not entered into any transactions with any of our directors, officers, beneficial owners of five percent or more
of our common shares, any immediate family members of the foregoing or entities of which any of the foregoing are also officers
or directors or in which they have a material financial interest, other than the compensatory arrangements described elsewhere
in this prospectus. We have adopted a policy that any transactions with directors, officers, beneficial owners of five percent
or more of our common stock, any immediate family members of the foregoing or entities of which any of the foregoing are also officers
or directors or in which they have a financial interest, will only be on terms consistent with industry standards and approved
by a majority of the disinterested directors of our Board.

Director Independence

Our Board may establish
the authorized number of directors from time to time by resolution. Our Board currently consists of eight (8) authorized members.
Generally, under the listing requirements and rules of the Nasdaq Stock Market, independent directors must comprise a majority
of a listed company’s board of directors. Our Board has undertaken a review of its composition, the composition of its committees
and the independence of each director. Our Board has determined that, other than Mr. Mattes and Dr. Windsor, by virtue
of their executive officer positions, none of our director nominees has a relationship that would interfere with the exercise of
independent judgment in carrying out the responsibilities of a director and that each is “independent” as that term
is defined under the applicable rules and regulations of the SEC and the listing requirements and rules of the Nasdaq Stock Market.
In making this determination, our Board considered the current and prior relationships that each nonemployee director nominee has
with our Company and all other facts and circumstances our Board deemed relevant in determining their independence, including the
beneficial ownership of our capital stock by each nonemployee director nominee. Accordingly, a majority of our directors are independent,
as required under applicable Nasdaq Stock Market rules, as of the date of this Report. With regard to Robert Mills, our Board determined
that Mr. Mills is independent notwithstanding his service as an officer of our company from January 2018 to December 2018 based
on NASDAQ guidelines that allow for an independent director’s past service as an executive officer provided such service
was an interim arrangement lasting less than one year.

Pre-Approval Policies and Procedures

The Audit Committee
has responsibility for selecting, appointing, evaluating, compensating, retaining and overseeing the work of the independent registered
public accounting firm. In recognition of this responsibility, the Audit Committee has established policies and procedures in
its charter regarding pre-approval of any audit and non-audit service provided to the Company by the independent registered public
accounting firm and the fees and terms thereof.

The Audit Committee
considered the compatibility of the provision of other services by its registered public accountant with the maintenance of their
independence. The Audit Committee approved all audit services provided by Marcum in 2019 and 2018. Except for certain corporate
tax compliance services, Marcum LLP did not perform any non-audit services in 2019 or 2018.
