CytoDyn Comments on Rosenbaum/Patterson Activist Group “Plan”

Company Is Successfully Executing on Multi-Faceted Strategy to Bring Leronlimab to Market

Activist Group Offers No New Compelling Strategic Direction and its “Plan” Includes Numerous Misrepresentations and Misleading Statements

Activist Group’s Continued Attempts to Link CytoDyn to IncellDx Are Troubling, Given Connections Between IncellDx and Group’s Nominees

Shareholders Do Not Need to Take Any Action at this Time

CytoDyn Inc. (OTCQB: CYDY) (“CytoDyn” or the “Company”), a late-stage biotechnology company developing leronlimab, a CCR5 antagonist with the potential for multiple therapeutic indications, today responded to the “plan” put forward by an activist group led by Paul Rosenbaum and Bruce Patterson (the “Rosenbaum/Patterson Group” or the “Activist Group”):

CytoDyn is highly focused on the expeditious development of leronlimab to help patients with critical needs. Clinical development of any product is a multi-year endeavor. Within this context, the Company has acted as quickly as possible – bringing leronlimab from the Phase 2b stage to successfully completing a pivotal Phase 3 (p=0.0032) in seven years, which was significantly faster than leronlimab’s progress with its prior owner. CytoDyn is exploring several different indications for leronlimab. These include COVID-19 critical and severe hospitalized patients as well as long-haulers, HIV and 22 different cancer types. The Company strongly believes in the drug’s potential – especially given that it is variant agnostic when it comes to treating COVID-19.

The Activist Group’s missive is not a “plan”; it appears to be a misguided and misleading attempt to discredit the significant efforts of CytoDyn to bring leronlimab’s lifesaving potential to market to help patients and drive value for shareholders. The success of these efforts is clearly demonstrated by the increasingly long list of positive developments that CytoDyn has announced recently, including the clearance from Brazil’s regulatory authority, ANVISA (Agência Nacional de Vigilância Sanitária), to begin an additional Phase 3 CD16 clinical trial of leronlimab with IV treatment, which the Company believes will have an enormous advantage over treatment via subcutaneous (SQ) injections. CytoDyn will continue to work tirelessly towards approvals for leronlimab and are laser focused on doing what is best for all shareholders.

Readers of the Activist Group’s “plan” should consider the following:

The Activist Group Offers No New Compelling Strategic Direction with Respect to Cancer Therapy Approval

• CytoDyn is currently working with some of the top oncological opinion leaders in the world from well-respected academic institutions. These experts will assist CytoDyn in determining the appropriate targets and the most efficient path to Breakthrough Therapy designation and approval of leronlimab.¹

• CytoDyn has already stated publicly that it believes leronlimab has a potential synergistic effect with PD-L1/PD-1 inhibitors, PARP inhibitors, antibody-drug conjugates, and chemotherapy. However, since the first cancer indication with mTNBC has shown what the Company believes to be very strong results, CytoDyn will focus obtaining Breakthrough Therapy designation as the fastest path to approval. Approval of leronlimab in combination with other therapies will take at least another two to three years – but if the Company receives approval for mTNBC, then label expansion would be much faster for any additional cancer indication.²

• CytoDyn recently signed a contract with a top oncology academic institution to evaluate the anti-tumor effect of leronlimab and checkpoint inhibitors.³

• The Company has already publicly discussed the potential value of leronlimab with combination therapy. Further, current management has first-hand experience with the potential of leronlimab in monotherapy for patients who respond to leronlimab single agent therapy and in combination therapy when other treatments have failed – or when a patient is intolerant of certain standard of care regimens and therefore their background therapy is their last recourse.⁴

• Regarding pharmaceutical partners, CytoDyn has been in contact with potential partners both domestically and internationally. The main catalyst for partnerships is data, which CytoDyn did not have previously. The Company now has that data and is evaluating options including partnerships with academic institutions and major pharmaceutical companies.⁵

The Activist Group’s Continued Attempts to Link CytoDyn to IncellDx Are Troubling

Patient safety and data accuracy will always remain CytoDyn’s main concern. Based on its first-hand experience in working with IncellDx, CytoDyn sees any relationship between IncellDx and the Company as a liability for shareholders rather than an asset. That is why the Activist Group’s suggestion to define cancer targets using the IncellDx H-Scoring system is misguided – particularly since the Group proposes that CytoDyn license this system from IncellDx. Consider the following:

• It is clearly a direct conflict of interest for Dr. Bruce Patterson to continuously seek to force a relationship between IncellDx and CytoDyn while trying to gain a seat on the Board of Directors of CytoDyn.

• Together with his wife, Dr. Patterson owns approximately 34% of IncellDx and Jeff Beaty, another member of the Activist Group, owns about 2.3% of IncellDx. They previously failed to disclose the frequent requests for CytoDyn to purchase IncellDx for as much as $350 million. They clearly have a financial interest in licensing the IncellDx H-scoring system. While the Activist Group’s proposed slate of directors recently tried to distance themselves from any relationship between IncellDx and CytoDyn, we believe it is evident this is not truly the case.

• To add insult to injury, the Activist Group not only choose Dr. Patterson to be on its slate, it also supports the use of Dr. Patterson’s unproven test, which would allow Dr. Patterson to profit from CytoDyn.

The Activist Group’s Plan Includes Numerous Mistakes

These mistakes include the following:

• The Activist Group’s implication that CytoDyn would use Amarex as its clinical research organization (CRO) for its current oncology studies is incorrect. CytoDyn has already announced publicly that it will not be using Amarex for current oncology studies going forward and the Company is identifying and interviewing Oncology-focused CRO’s with the input of the executive team, KOL’s, and Scientific Advisory Board.⁶

• CytoDyn’s current oncology program is not dependent on the success of the potential approval of the long hauler’s indication, as the Activist Group implies. Dr. Nader Pourhassan has a proven track record of raising capital of over $420 million to support the various indications of leronlimab. By contrast, the Activist Group’s proposed slate of directors does not have a proven track record of raising capital, putting the Company potentially at financial risk. We believe the Activist Group’s financing proposal is a clear indication of their lack of experience.

• The Activist Group’s depiction of the timing for CytoDyn’s cancer trial is incorrect. The Company’s executive team is in final stage of completion of the protocol for submission of its basket trial for 22 cancers with the advice of top oncologists with clinical experience (not pathologists, such as Dr. Bruce Patterson).⁷ Current FDA guidelines estimate an approval process for a drug to be 12 years, yet CytoDyn has come close to potential approval for multiple indications in just seven years.

Shareholders should not be fooled by the Activist Group’s misleading “plan”. The bottom line is that this Group has motives and incentives that differ greatly from those of all other shareholders – while misleading shareholders about their intentions, conflicts of interest, legal transgressions and professional competencies.

Litigation/Proxy Process Update

Shareholders do not need to take any action at this time. CytoDyn urges shareholders to ignore any calls, emails or mailings from the Activist Group. As a reminder, CytoDyn believes that the Activist Group’s notice of director nominations was invalid because it failed to comply with the Company’s by-laws. The Activist Group has sued the Company in the Delaware Court of Chancery, seeking declaratory judgment that their nomination notice was valid. This case remains pending, and the Court has scheduled a hearing for October 6, 2021. Unless the Court disagrees with CytoDyn, the Activist Group’s director nominations will be disregarded, and no proxies or votes in favor of its nominees will be recognized or tabulated at the 2021 Annual Meeting.

The Company has filed its preliminary proxy materials with the SEC. Shareholders will be receiving the Company’s definitive proxy materials once they have been reviewed by the SEC. To the extent shareholders have voted on the Activist Group’s proxy card, they can vote on the Company’s proxy card once it becomes available to revoke their vote on the Activist Group’s card. Only the latest-dated proxy card counts.

CytoDyn will continue to update shareholders on further developments as appropriate.

About CytoDyn

CytoDyn is a late-stage biotechnology company developing innovative treatments for multiple therapeutic indications using leronlimab, a novel humanized monoclonal antibody targeting the CCR5 receptor. CCR5 plays a critical role in the ability of HIV to enter and infect healthy T-cells and appears to be implicated in tumor metastasis and immune-mediated illnesses, such as NASH.

CytoDyn successfully completed a Phase 3 pivotal trial using leronlimab combined with standard antiretroviral therapies in HIV-infected patients who were heavily treatment-experienced individuals with limited treatment options. CytoDyn is working diligently to resubmit its BLA for this HIV combination therapy since receiving a Refusal to File in July 2020 and subsequently meeting with the FDA telephonically to address their written guidance concerning the filing. On July 1, 2021, CytoDyn announced that it had submitted a dose justification report to the FDA, an integral step in the resubmission process for its BLA. CytoDyn also completed a Phase 2b/3 investigative trial with leronlimab used as a once-weekly monotherapy for HIV-infected patients. CytoDyn plans to initiate a registration-directed study of leronlimab monotherapy indication. If successful, it could support a label expansion approval. Clinical results to date from two trials have shown that leronlimab can maintain a suppressed viral load in a sub-population of R5 HIV patients who chose to switch from their daily pills regimen to once-a-week subcutaneous dose of leronlimab. Several patients on leronlimab’s Phase 2b extension arm have remained virally suppressed for almost 7 years and many patients in our Phase 2b/3 investigative trial are passing two and some four years of monotherapy with suppressed viral load.

CytoDyn is also conducting a Phase 2 clinical trial with leronlimab in mTNBC, a Phase 2 basket trial in solid tumor cancers (22 different cancer indications), Phase 2 investigative trial for post-acute sequelae of SARS COV-2, also known as COVID-19 long haulers, and a Phase 2 clinical trial for NASH. CytoDyn has already completed a Phase 2 and Phase 3 trial for mild-to-moderate and severe-to-critical COVID-19 patients, respectively, for which CytoDyn did not meet its primary or secondary endpoints, except for the secondary endpoint in the critically ill subpopulation.
