CRANFORD, N.J., December 15, 2021 -- Citius Pharmaceuticals,

Inc. ("Citius" or the "Company") (Nasdaq: CTXR), a late-stage biopharmaceutical company

dedicated to the development and commercialization of first-in-class critical care products with a focus on oncology, anti-infective products

in adjunct cancer care, unique prescription products, and stem cell therapies, today reported business and financial results

for the fiscal full year ended September 30, 2021.

Fiscal Full Year 2021 Business Highlights and Subsequent Developments

Financial Highlights

"2021 was a transformative year for Citius as we positioned the

company financially and strategically to drive growth. We raised more than $120 million in proceeds to support our activities, providing

us with the flexibility to advance our clinical programs and invest in opportunities for additional growth. With the recent addition of

cancer immunotherapy I/ONTAK to our portfolio, we now have a robust pipeline that includes two late Phase 3 programs and three potentially

first-in-class products," stated Myron Holubiak, President and Chief Executive Officer of Citius Pharmaceuticals.

"As we move into 2022, we anticipate multiple positive milestones.

These include: accelerated enrollment and completion of the Mino-Lok trial during

the year, topline results in the first half of 2022 for the recently completed I/ONTAK Pivotal Phase 3 trial followed by a BLA submission

in the second half of the year, initiation of the Halo-Lido study in early 2022 and completion of the study by the end of the year, and

continued progress on Mino-Wrap and our iPSC-derived mesenchymal stem cells for the treatment of acute respiratory distress syndrome (ARDS).

With the addition of key personnel to our clinical, manufacturing and commercial teams, we are aligning our resources to ensure continued

progress across each of our development programs, and the successful launch of potentially two commercial products in 2023. We believe

our strong balance sheet will allow us to execute our development programs as planned in 2022 and we do not anticipate a need to raise

additional capital in the coming year," concluded Mr. Holubiak.

Full Year 2021 Financial

As of September 30, 2021, the Company had $70.1 million in cash and

cash equivalents. During the fiscal year ended September 30, 2021, the Company received net proceeds of $120.6 million from financing

In January 2021, the Company closed a private placement for common

stock and warrants totaling gross proceeds of approximately $20 million and net proceeds of $18.5 million. In February 2021, the Company

closed a registered direct offering of its common stock and warrants for gross proceeds of $76.5 million and net proceeds of $71 million.

During the year ended September 30, 2021, the Company received $31.2 million in proceeds from the exercise of common stock options and

On June 21, 2021, stockholders approved an amendment to the Company's

Articles of Incorporation to increase the authorized number of shares from 210,000,000 to 410,000,000 and the authorized number of common

shares from 200,000,000 to 400,000,000. As of September 30, 2021, the Company had 145,979,429 common shares issued and outstanding.

In 2021, the Company raised a total of $127.6 million through financing

activities. We estimate that we will have sufficient funds for our operations through March 2023.

Research and Development (R&D) Expenses

R&D expenses were $12.2 million for the full year ended September

30, 2021, compared to $8.8 million for the full year ended September 30, 2020. The increase of $3.4 million is primarily due to an increase

in research and development expenses for our proposed novel cellular therapy for ARDS of $6.1 million, of which $5 million was a license

fee paid to Novellus, and an increase in R&D expenses related to the I/ONTAK license and Mino-Wrap, offset by decreases in research

and development expenses related to our Mino-Lok and Halo-Lido product candidates.

We expect that research and development expenses will increase in fiscal

2022 as we continue to focus on our Phase 3 trial for Mino-Lok , progress the Halo-Lido product candidate, and continue

our research and development efforts related to ARDS, Mino-Wrap and I/ONTAK (E7777).

General and Administrative (G&A) Expenses

G&A expenses were $9.8 million for the full year ended September

30, 2021, compared to $8.1 million for the full year ended September 30, 2020. The primary reason for the increase is costs associated

with additional compensation costs for new employees and performance bonuses. General and administrative expenses consist primarily of

compensation costs, professional fees related to our capital raising activities, corporate development services, and investor relations.

Stock-based Compensation Expense

For the full year ended September 30, 2021, stock-based compensation

expense was $1.5 million as compared to $0.8 million for the prior year. The increase reflects expenses related to new grants made by

Citius and the NoveCite stock option plan.

Net loss was $23.1 million, or ($0.23) per share for the year ended

September 30, compared to a net loss of $17.5 million, or ($0.45) per share for the year ended September 30, 2020. The increase in net

loss is primarily due to the $3.4 million increase in our research and development expenses and a $1.6 million increase in general and

administrative expenses.
