Overview

Enzon Pharmaceuticals, Inc. (together with its subsidiaries, the "Company," "Enzon," "we" or "us") is positioned as a public company acquisition vehicle, where it can become an acquisition platform and more fully utilize its net operating loss carryforwards ("NOLs") and enhance stockholder value.



In September 2020, we initiated a rights offering for our common and preferred
stock (see below and Note 12 to our Condensed Consolidated Financial
Statements), which closed in October 2020, and we realized $43.6 million in
gross proceeds. This has enabled us to embark on our plan to realize the value
of our approximately $103.5 million net operating loss carryforwards ("NOLs") by
acquiring potentially profitable businesses or assets. To protect the NOLs, in
August 2020, our Board of Directors adopted a Section 382 rights plan (see
Note 11 to our Condensed Consolidated Financial Statements).

Historically, we had received royalty revenues from licensing arrangements with
other companies primarily related to sales of certain drug products that
utilized Enzon's proprietary technology. In recent years, we have had no
clinical operations and limited corporate operations. We cannot assure you that
we will earn material future royalties or milestones.

We have a marketing agreement with Micromet AG, now part of Amgen, Inc. (the
"Micromet Agreement"), pursuant to which we may be entitled to a share of
certain milestone and royalty payments if Vicineum, a drug being developed by
Sesen Bio, Inc. ("Sesen"), is approved for the treatment of non-muscle invasive
bladder cancer. In a press release dated February 16, 2021, Sesen announced that
the U.S. Food and Drug Administration (the "FDA") has accepted for filing
Sesen's Biologic License Application ("BLA") for Vicineum. The FDA further
granted Priority Review, with a target Prescription Drug User Fee Act ("PDUFA")
date for a decision on the BLA of August 18, 2021. Accordingly, we earned a
milestone of $409,430 in the first quarter of 2021, all of which was received by
June 30, 2021. However, on August 13, 2021, Sesen announced that it had received
a Complete Response Letter ("CRL") from the FDA and that the FDA had determined
that it cannot approve the BLA for Vicineum in its present form and had provided
recommendations specific to additional clinical/statistical data and analyses in
addition to Chemistry, Manufacturing and Controls ("CMA") issues pertaining to a
recent preapproval inspection and product quality. In a press release that Sesen
issued on November 1, 2021, it noted that on October 29, 2021 it had a CMA Type
A meeting with the FDA and reviewed issues related to CMC that will be further
discussed during the review of the BLA for Vicineum upon potential resubmission.
Sesen, also noted that it is preparing for the clinical Type A meeting to
discuss the recommendations specific to additional clinical/statistical data and
analyses that the FDA raised in the CRL. It expects that meeting to take place
later in 2021. In a filing with the U. S. Securities and Exchange Commission
("SEC") in March 2021, Sesen noted that it had received notice from the European
Medicines Agency ("EMA") that its Marketing Authorization

                                       12



Application ("MMA") for Vicineum was found to be valid and the review procedure has officially started. Accordingly, we earned and received an additional milestone of $292,284 in the second quarter of 2021.


Subsequently, on August 25, 2021, Sesen announced that it had withdrawn its
application to market Vicineum in Europe. Due to the challenges associated with
developing and obtaining approval for drug products, and the lack of involvement
by us in the development and approval process, there is substantial uncertainty
as to whether we will receive additional milestone or any royalty payments under
the Micromet Agreement. We will not recognize revenue until all revenue
recognition requirements are met.

Acquisition Activities



Our Board of Directors and our management are actively involved in pursuing,
sourcing, reviewing and evaluating various potential acquisition transactions
consistent with our long-term strategy. Our management and Board of Directors
have made a number of contacts and engaged in discussions with principals of
individual companies and financial advisors on behalf of various individual
companies, while continuing to evaluate potential transactions. To date, we have
not developed any actionable transactions. We will continue to update our
stockholders as material developments arise.

Throughout this Management's Discussion and Analysis, the primary focus is on
our results of operations, cash flows and financial condition. The percentage
changes throughout the following discussion are based on amounts stated in

thousands of dollars.

Results of Operations

Change 2020 Milestone and royalty revenues $ - (100) % $ 8 $ 672 3,633 % $ 18






In the nine and three-month periods ended September 30, 2021, we earned
approximately $701,000 and $0, respectively, in milestone revenue from Sesen.
Separately, in the nine and three-month periods ended September 30, 2021, we
were notified by Merck of an approximate $29,000 and $0, respectively, repayment
they believe they are owed of previously-paid royalties on PegIntron. Royalty
revenues from sales of PegIntron by Merck accounted for 100% of our total
milestone and royalty revenues for the nine-month and three-month periods ended
September 30, 2020. Sales of PegIntron-related products will continue their
declining trend and we expect to receive little or no future royalties from
Merck. Our right to receive royalties on U.S. and European sales of PegIntron
expired in 2016 and 2018, respectively, expired in Malaysia in 2020, and will
expire in Japan in December 2021 and Chile in April 2024.

Merck has not yet reported royalty revenues earned by us for product sales and/or recoupments for returns and rebates for the quarter ended September 30, 2021, but neither is expected to be material.

Operating Expenses:

General and Administrative (in thousands of dollars):




                                          Three Months Ended September 30,            Nine Months Ended September 30,

General and administrative expenses remained fairly consistent, increasing by
approximately $9,000, or 1%, to $910,000 for the nine months ended September 30,
2021 from $901,000 for the first nine months of 2020.

General and administrative expenses decreased by approximately $187,000, or 45%,
to $228,000 for the three months ended September 30, 2021 from $415,000 for the
third quarter of 2020. The decrease in expense is substantially attributable to
the

                                       13


disproportionate legal fees and consulting fees that were incurred in connection with the Section 382 Rights Plan during the third quarter of 2020.

Tax Expense:

We incurred no tax expense during the third quarters of 2021 and 2020 and a tax expense of approximately $2,000 in the first nine months of 2021 and $2,000 during the prior comparable period to reflect New Jersey state minimum taxes.

Liquidity and Capital Resources



Our current source of liquidity is our existing cash and cash equivalents on
hand, which includes the approximately $43.6 million of gross proceeds from our
Rights Offering. (See Note 12 to the Condensed Consolidated Financial
Statements.) While we no longer have any research and development activities, we
continue to retain rights to receive royalties and milestone payments from
existing licensing arrangements with other companies and, accordingly, we
received milestone revenue of approximately $701,000 from Sesen during the nine
months ended September 30, 2021. We may become entitled to additional milestone
payments as a result of regulatory approvals and initial sales in the United
States and Europe in connection with Vicineum. We may share in royalty payments
upon additional sales of Vicineum, We believe that our existing cash and cash
equivalents on hand will be sufficient to fund our operations, at least, through
November 2022. Our future royalty revenues may be de minimis over the next
several years unless and until we receive a share of milestone and royalty
payments resulting from the approval and sale of Vicineum, and we cannot assure
you that we will receive any royalty, milestone or other payments or revenues.

While we are positioned as a public company acquisition vehicle, where we can become an acquisition platform and more fully utilize our NOLs and enhance stockholder value, we cannot assure you that we will succeed in making acquisitions that are profitable and that will enable us to utilize our NOLs.



Cash used in operating activities represents a net loss, as adjusted for certain
non-cash items including the effect of changes in operating assets and
liabilities. Cash used in operating activities during the nine months ended
September 30, 2021 was approximately $251,000, as compared to cash provided by
operating activities of approximately $165,000 during the comparable period in
2020. The decrease of approximately $416,000 was significantly attributable to
the collection of tax credits of approximately $1.0 million during the
comparable period in 2020, as partially offset by the decrease in net loss of
approximately $650,000 in the current period.

The net effect of the foregoing was a decrease of cash and cash equivalents of
approximately $251,000, from $48.1 million at December 31, 2020 to $47.9 million
at September 30, 2021.

Off-Balance Sheet Arrangements

As part of our ongoing business, we do not participate in transactions that generate relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities (SPEs), which would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually limited purposes. As of September 30, 2021, we were not involved in any SPE transactions.

Critical Accounting Policies and Estimates


A critical accounting policy is one that is both important to the portrayal of a
company's financial condition and results of operations and requires
management's most difficult, subjective or complex judgments, often as a result
of the need to make estimates about the effect of matters that are inherently
uncertain.

Our consolidated financial statements are presented in accordance with
accounting principles that are generally accepted in the United States ("U.S.
GAAP"). All applicable U.S. GAAP accounting standards effective as of September
30, 2021 have been taken into consideration in preparing the consolidated
financial statements. The preparation of the consolidated financial statements
requires estimates and assumptions that affect the reported amounts of assets,
liabilities, revenues, expenses and related disclosures. Some of those estimates
are subjective and complex, and, consequently, actual results could differ from
those estimates. The following accounting policies and estimates have been
highlighted as significant because changes to certain judgments and assumptions
inherent in these policies could affect our consolidated financial statements.

                                       14


We base our estimates, to the extent possible, on historical experience. Historical information is modified as appropriate based on current business factors and various assumptions that we believe are necessary to form a basis for making judgments about the carrying value of assets and liabilities. We evaluate our estimates on an ongoing basis and make changes when necessary. Actual results could differ from our estimates.

Revenues



Royalties under our license agreements with third-parties and pursuant to the
sale of our former specialty pharmaceutical business are recognized when
reasonably determinable and earned through the sale of the product by the
third-party and collection is reasonably assured. Notification from the
third-party licensee of the royalties earned under the license agreement is the
basis for royalty revenue recognition. This information generally is received
from the licensees in the quarter subsequent to the period in which the sales
occur.

Contingent payments due under the asset purchase agreement for the sale of our
former specialty pharmaceutical business are recognized as revenue when the
milestone has been achieved, collection is assured, such payments are
non-refundable and no further effort is required on the part of the Company or
the other party to complete the earning process.

Income Taxes



Under the asset and liability method of accounting for income taxes, deferred
tax assets and liabilities are recognized for the estimated future tax
consequences attributable to differences between the financial statement
carrying amounts of existing assets and liabilities and their respective tax
bases and operating loss and tax credit carryforwards. Deferred tax assets and
liabilities are measured using enacted tax rates expected to apply to taxable
income in the years in which those temporary differences are expected to be
recovered or settled. A valuation allowance on net deferred tax assets is
provided for when it is more likely than not that some portion or all of the
deferred tax assets will not be realized. As of September 30, 2021, we believe,
based on our projections, that it is more likely than not that our net deferred
tax assets, including our net operating losses from operating activities, will
not be realized. We are positioned as a public company acquisition vehicle,
where we can become an acquisition platform and more fully utilize our NOLs. We
intend to acquire profitable businesses, entities or revenue streams that will
generate sufficient income so that we can utilize our approximately $103.5
million NOLs. At this time, however, we cannot assure you that we will be
successful in doing so. Accordingly, our management will continue to assess the
need for this valuation allowance and will make adjustments when appropriate.
Additionally, our management believes that our NOLs will not be limited by any
changes in our ownership as a result of the successful completion of the Rights
Offering (See Note 12 to the Condensed Consolidated Financial Statements). We
recognize the benefit of an uncertain tax position that we have taken or expect
to take on the income tax returns we file if it is more likely than not that we
will be able to sustain our position.

Forward-Looking Information and Factors That May Affect Future Results



This Quarterly Report on Form 10-Q contains forward-looking statements within
the "safe harbor" provisions of the Private Securities Litigation Reform Act of
1995. All statements contained in the Quarterly Report on Form 10-Q, other than
statements that are purely historical, are forward-looking statements.
Forward-looking statements can be identified by the use of forward-looking
terminology such as the words "believes," "expects," "may," "will," "should,"
"potential," "anticipates," "plans" or "intends" or the negative thereof, or
other variations thereof, or comparable terminology, or by discussions of
strategy. Forward-looking statements are based upon management's present
expectations, objectives, anticipations, plans, hopes, beliefs, intentions or
strategies regarding the future and are subject to known and unknown risks and
uncertainties that could cause actual results, events or developments to be
materially different from those indicated in such forward-looking statements,
including, but not limited to, the following risks and uncertainties:

? We may be unsuccessful in our strategy to fully utilize our NOLs and other tax

assets and enhance stockholder value as a public company acquisition vehicle.

? Our sources of revenue are limited and we may incur losses for the foreseeable

future.

In recent years, we derived most of our royalty revenues from continued sales

? of PegIntron, which have been in sharp decline. In addition, our right to

receive royalties on U.S. and European sales of PegIntron expired in 2016 and


   2018, respectively, which has negatively impacted our royalty revenues.


                                       15


Our rights to receive royalties on sales of PegIntron and sales of other drug

products have expired in various jurisdictions and, except for Vicineum, will,

? by 2024, expire world-wide. We currently do not anticipate any significant


   royalties from other sources, but we may acquire new sources of royalty
   revenues.

We have an agreement with Sesen from which we have recently received milestone

payments and, potentially, may be entitled to receive future royalty payments

related to sales of Vicineum, a drug being developed by Sesen for the treatment

of non-muscle invasive bladder cancer. In August 2021, Sesen announced that it

had received a Complete Response Letter from the FDA and that the FDA had

determined that it cannot approve the BLA for Vicineum in its present form and

had provided recommendations specific to additional clinical/statistical data

and analyses in addition to CMA issues pertaining to a recent preapproval

inspection and product quality. In a press release that Sesen issued on

? November 1, 2021, it noted that on October 29, 2021 it had a CMA Type A meeting

with the FDA and reviewed issues related to CMC that will be further discussed

during the review of the BLA for Vicineum upon potential resubmission. Sesen,

also noted that it is preparing for the clinical Type A meeting to discuss the

recommendations specific to additional clinical/statistical data and analyses

that the FDA raised in the CRL. It expects that meeting to take place later in

2021. Also, in August 2021, Sesen announced that it had withdrawn its

application to the EMA to market Vicineum in Europe. There is no guarantee that

Sesen will receive approval from the FDA or EMA and, even if so, whether there

will significant sales of Vicineum so as to generate material royalties to us.

The unprecedented actions taken globally to control the spread of COVID 19, as

well as the uncertainty surrounding the success of global vaccination efforts,

? may materially and adversely affect our future right to receive licensing fees,

milestone payments and royalties on product candidates that are being developed

by third parties.

We have reallocated all employment responsibilities and outsourced all

? corporate functions, which makes us more dependent on third parties to perform

these corporate functions.

We may be subject to a variety of types of product liability or other claims

? based on allegations that the use of our product candidates by participants in

our previously conducted clinical trials has resulted in adverse effects, and

our insurance may not cover all product liability or other claims.

? Our revenues largely depend on proprietary rights, which may offer only limited

protection against the development of competing products.

? We are party to license agreements whereby we may receive royalties and or

milestone payments from products subject to regulatory approval.

? The price of our common stock has been, and may continue to be, volatile.

Our common stock is quoted on the OTCQX market of the OTC Markets Group, Inc.,

? which has a very limited trading market and, therefore, market liquidity for

our common stock is low and our stockholders' ability to sell their shares of


   our common stock may be limited.


   The declaration of dividends is within the discretion of our Board of

Directors, subject to any applicable limitations under Delaware corporate law,

as well as the requirements of the Series C Preferred Stock. Our ability to pay

? dividends in the future depends on, among other things, our fulfillment of the

conditions of the Series C Preferred Stock, fluctuating royalty revenues, our

ability to acquire other revenue sources and our ability to manage expenses,

including costs relating to our ongoing operations.

? We have adopted a Section 382 rights plan, which may discourage a corporate

takeover.

Anti-takeover provisions in our charter documents and under Delaware corporate

? law may make it more difficult to acquire us, even though such acquisitions may


   be beneficial to our stockholders.


                                       16


The terms of our outstanding Series C Preferred Stock and the issuance of

? additional series of preferred stock may adversely affect rights of our common

stockholders.

? The interests of our significant stockholders may conflict with the interests

of other stockholders.




A more detailed discussion of these risks and uncertainties and other factors
that could affect results is contained in our filings with the U.S. Securities
and Exchange Commission, including our Annual Report on Form 10-K for the year
ended December 31, 2020. These risks and uncertainties and other factors should
be considered carefully and readers are cautioned not to place undue reliance on
such forward-looking statements. As such, no assurance can be given that the
future results covered by the forward-looking statements will be achieved. All
information in this Quarterly Report on Form 10-Q is as of the date of this
report, unless otherwise indicated, and we undertake no duty to update this
information.
