June 14, 2021

Dear Stockholder,

The Board of Directors (the "Board") thanks you for your continued investment in Adamis Pharmaceuticals Corporation ("Adamis" or the "Company"). We are writing to you today because this year's Annual Meeting of Stockholders (the "Annual Meeting") on July 16, 2021 is an important one as Adamis continues pursuing breakthrough drugs and treatments for allergies, respiratory diseases and opioid-induced overdoses.

As the world continues to battle the COVID-19 pandemic and the United States grapples with a harrowing opioid epidemic, our Board and management are working to develop and commercialize an innovative pipeline of sorely needed solutions. We believe our work has the potential to not only create enduring value for stockholders, but also society as a whole. That is why we are urging you to vote on the WHITE proxy card to re-elect all five members of the Board at next month’s Annual Meeting.

Over the past year, we have been executing a disciplined and focused strategy in order to:

• Successfully navigate the unprecedented market volatility and operating challenges caused by the pandemic.
• Maintain a strong capital position and healthy balance sheet.
• Pursue potential regulatory approval for our high-dose naloxone injection product candidate, which is intended for the treatment of opioid overdose.
• Advance Tempol, which is a potential breakthrough treatment for COVID-19, through the clinical testing phase.
• Explore partnerships and collaborations that can help us accelerate pipeline initiatives and potentially realize value on an accelerated basis.

Although we recognize there is significant work in front of us in order to deliver the value that our stockholders desire, we believe Adamis has strong momentum heading into the back half of 2021. We have achieved total stockholder returns of more than 75% on a one-year basis and more than 85% on a year-to-date basis.¹ This represents significant outperformance relative to the Nasdaq Biotechnology Index and the Nasdaq US Small Cap Biotechnology Index over the same periods.

By re-electing our full Board next month, we believe stockholders will position Adamis to sustain its momentum and remain on a path to long-term value creation.

YOUR BOARD AND MANAGEMENT TEAM HAVE ASSEMBLED A PRODUCT PIPELINE THAT WE BELIEVE HAS SIGNIFICANT POTENTIAL.

It is important to underscore that Adamis has an attractive portfolio of approved products and clinical-stage treatments. We believe the diversity of our portfolio offers us various potential paths to value creation for stockholders. Select highlights include:

SYMJEPI^® (epinephrine) Injection

• Since completing the transition of SYMJEPI from Sandoz in the fourth quarter of 2020, our new commercial partner – US WorldMeds – continues to make gains in the epinephrine market.
  • In January 2021, both approved SYMJEPI products became available through the Walgreens Prescription Savings Club at a discounted price of $99.99 per two-pack.
  • Based on third-party market data, we believe SYMJEPI unit sales have increased approximately 90% on a year-over-year basis for the period beginning December 2020 and ending April 2021. We attribute much of this growth to our new partnership.
• We expect the Walgreens arrangement, along with other commercial initiatives currently underway, to continue fueling positive sales trends for SYMJEPI products.

ZIMHI™ (naloxone) Injection

• We announced this month that the U.S. Food and Drug Administration (“FDA”) has accepted for review our resubmitted New Drug Application (“NDA”) for ZIMHI, which is a higher naloxone injection product candidate for the treatment of opioid overdose.
  • We received FDA correspondence relating to the NDA, stating that the agency had completed its filing review and had determined that the NDA was sufficiently complete to permit a substantive review.
  • The FDA also provided a target action date under the Prescription Drug User Fee Act of November 12, 2021.
• During the first quarter of this year, we submitted responses to the FDA to address deficiencies identified in the complete response letter relating to our NDA for ZIMHI. We also requested a Type-A meeting with the agency.
  • In April, we met with the FDA to discuss the responses and the regulatory path forward for ZIMHI.

Tempol

• The National Institutes of Health (“NIH”) recently identified the experimental drug Tempol, as a potentially potent antiviral for COVID-19. In 2020, we in-licensed patent and related intellectual property rights to Tempol pursuant to a license agreement for certain fields, including COVID-19.
  • According to a study of cell cultures conducted by NIH researchers, Tempol demonstrated an ability to limit SARS-CoV-2 infection by impairing the activity of a viral enzyme known as RNA replicase.
  • The NIH researchers also found that Tempol “doses used in their antiviral studies could be likely achieved in tissues that are the primary targets for the virus.”²
• In February, our Investigational New Drug Application (“IND”) relating to a protocol for a clinical trial of Tempol in COVID-19 received FDA clearance to begin clinical testing.
  • We are now working with a large clinical research organization that has started key operational aspects of the clinical study, including site selection, site agreements and vendor agreements.
• We are also engaged in activities intended to support preparing an IND for a study of Tempol for the treatment of Radiation Dermatitis.
  • The manufacturer for the topical Tempol gel has been identified and drug substance is available for manufacturing.
• Adamis is also investigating the utility of Tempol for the treatment of cocaine and methamphetamine abuse.
  • Several published studies in animals suggest that Tempol significantly decreases the urge for both cocaine and methamphetamines and cocaine abuse. Methamphetamine abuse is a significant unmet public health problem that parallels the opioid epidemic.
  • According to the Centers for Disease Control, methamphetamine use resurged in the United States from 2015 to 2018, rising to an annual use rate of 59.7 per 1,000 adults, or approximately 14.7 million individuals per year.

While there is significant competition in the marketplace and uncertainty always looms, we are confident that Adamis is focused on the right assets and the right opportunities. Our Board has several decades of experience operating at the highest levels of the biotechnology and pharmaceuticals industries. We believe this experience will be critical as Adamis competes and works to accelerate clinical testing progress and prospective regulatory approvals in the coming quarters.

ADAMIS HAS THE RIGHT LEADERSHIP FOR THIS PIVOTAL MOMENT IN TIME

We contend that Adamis is at the precipice of major developments and value-generating progress. This is why we believe maintaining an aligned, experienced and stable Board is essential.

Unfortunately, Jerald A. Hammann – an opportunistic and 0.01% stockholder with no biopharmaceutical expertise, no public company experience and no articulated plan – has initiated costly litigation with us and is attempting to run a slate of directors to take control of the Board at this year’s Annual Meeting. Mr. Hammann took these actions after we rejected his demand that Adamis provide him a lucrative consulting agreement prior to becoming a stockholder. We believe Mr. Hammann’s apparent track record of launching value-destructive activist campaigns and trying to secure what we view as greenmail should be a flashing red light for stockholders.

If Mr. Hammann were to achieve his self-serving objective, we believe it would be disastrous for our investors. We do not see how Adamis would be able to build on its momentum and maintain its valuable relationships with providers, partners and regulators if its highly-experienced directors and presumably management were replaced at this critical phase.

We urge stockholders seeking to realize the potential of our pipeline to carefully consider the sizable risks posed by Mr. Hammann’s campaign. We believe the far superior and safer path is re-electing directors who have presided over strong momentum, significant stock price appreciation and a viable strategy over the past year. Our Board has a clear vision for value creation.

Once again, we thank you for your investment in Adamis. We recognize that there have been ups-and-downs over the past several years as the Company invested significantly in research and development and navigated often lengthy regulatory processes. However, we firmly believe that Adamis is on the right path now that we have tangible pipeline momentum. We urge you to vote on the WHITE proxy card to elect our full five-member slate and help us sustain the Company’s momentum.

Sincerely,

***
