Company Reports Revenue of $35.8 million up 395% from prior year Total Capital invested across all SPV Series: approximately $292 million Record Date of May 15th for $9 Million Dividend Payment NEW YORK, May 13, 2026 /PRNewswire/ -- Dominari Holdings Inc. (Nasdaq: DOMH ) ("Dominari" or the "Company") today issued the following letter to shareholders:  Dear Shareholder, As we approach mid-year, I want to take this opportunity to thank you for being a Dominari shareholder and provide you with some updates. 10Q Summary The year is off to a strong start. As noted in our 10Q just filed with the SEC, first quarter revenue is up significantly, and we have increased our annual recurring revenue. Highlights from the 10Q include: Revenue of $35.8 million, up 395% from the prior year's first quarter's revenue of $7.2 million. Underwriting revenues totaled $32.9 million in Q1 2026 as compared to $5.6 million for Q1 2025, representing a 488% increase. Carried interest totaled $1.1 million as compared to no such revenue in Q1 2025. The Company's annual recurring revenue (ARR) increased to $1.1 million from $0.4 million at the end of Q1 2025, reflecting an increase of 189%. I encourage all shareholders to review the 10Q, which has been filed with the SEC. Company Legacy Holdings In addition, I'd like to discuss the Company's portfolio of legacy holdings. Dominari's wholly owned subsidiary, Dominari Labs, holds a portfolio of investments consisting of a mix of private company equity investments, public market holdings, preferred securities, convertible instruments, and warrant-enhanced positions. Some of our positions have seen significant unrealized appreciation, led by xAI, Groq, Cerebras, Skyline Builders Group, Datacentrex, and JFB Construction Holdings. As of mid-April 2026, the market value of our holdings in Dominari Labs exceeded $5,000,000.00. It is our intent to liquidate these positions when appropriate to augment shareholder value. Special Purpose Vehicles Another area of shareholder value is in our Special Purpose Vehicles ("SPVs"). There are speculative stories in the press about these SPVs, how they work and how Dominari runs our process. Much of what is in the media is incorrect. So, to clarify any potential confusion, I'd like to explain how our process works generally, keeping in mind that every situation is different. Generally, Dominari has two types of SPVs, "Unicorn SPVs" and "Venture SPVs." Unicorn SPVs, as the name suggests, focus on raising money to purchase shares in private companies with a valuation of one billion dollars or more, that are expected to go public. Examples of our Unicorn SPVs include the names such as, SpaceX, xAI, Groq, Cerebras. The second type of SPVs are referred to as Venture SPVs. To start, Dominari establishes a new Venture SPV for every new project. We then raise money for each new SPV, often without a specific target or use of proceeds in mind. Next, we work to identify public vehicles with operating businesses that might benefit from augmented business lines. Once a public vehicle has been identified, we conduct due diligence and collaborate with the public entity to align management with concept of augmenting its existing business. Once those issues, if any, are resolved, we then may take a position in the public entity for our clients and occasionally Dominari, through our SPVs. All of this work is done by Dominari, not our investors or advisors. Our investment thesis is simple: We identify and invest in U.S.-based leaders in new technologies that create American jobs and reduce U.S. dependence on foreign resources. The Skyline Builders/Kaz Resources transaction is an example. An American Venture SPV was formed, money was raised, and the work with Skyline Builders was performed before Kaz Resources was even approached. We then found an opportunity in Kaz Resources to lessen U.S. dependance on foreign governments for the incredibly important rare mineral of tungsten. Tungsten is crucial for the aerospace industry, military applications, electrical contacts, and heating elements. According to the U.S. Geological Survey, tungsten is not actively mined in the U.S. and approximately 80% of the world supply of tungsten is mined in China. So, in keeping with our thesis of creating American jobs and lessening our dependance on foreign governments, the combination of these two entities, created a more meaningful U.S. company that can help support America. With that background, a summary of the combined SPV data of all funds as of mid-April shows: Total capital invested across all series: approximately $ 292 million . Total estimated value of all series: approximately $ 1.27 billion . Estimated carry to Dominari: approximately $ 110 million .

Underwriting revenues increased over five-fold NEW YORK, May 13, 2026 /PRNewswire/ -- Dominari Holdings Inc. (Nasdaq: DOMH ) ("Dominari" or the "Company"), today announced highlights of its financial results for the quarter ended March 31, 2026, which were filed with the Securities and Exchange Commission ("SEC") in the Company's quarterly SEC Form 10Q. The Company stated that: "In the first quarter of 2026, we experienced continued revenue growth mainly from underwriting services, increased our annual recurring revenue from our management fees that we earn on deals that we bring to market from essentially nil 18 months ago to over $1 million, and currently retain carried interest positions in some exciting emerging companies that we believe will yield positive returns over the course of the next 24 months." While the net income reflects one-time, non-recurring expenses for Q1 2026, we believe that the margins we expect from our core business for the balance of the year, will result in improved operating income and bottom-line performance." The Company concluded, "the leadership team on our broker dealer subsidiary, led by Kyle Wool, continues to deliver world class investment banking services to our ever-growing list of clients, and we believe that will yield continued improved performance for the future." First Quarter 2026 Highlights Revenue of $35.8 million, up 395% from the prior year's first quarter's revenue of $7.2 million. Underwriting revenues totaled $32.9 million in Q1 2026 as compared to $5.6 million for Q1 2025, representing a 488% increase. Carried interest totaled $1.1 million as compared to no such revenue in Q1 2025. The Company's annual recurring revenue (ARR) increased to $1.1 million from $0.4 million at the end of Q1 2025, reflecting an increase of 189%. Loss from operations of $37.6 million, an increase of $4.7 million compared to a loss of $32.9 million in the comparable period in 2025, reflecting increased one-time variable expenses in the quarter. Other expense of $6.8 million as compared to other income of $0.4 million in Q1 2025. This book loss was primarily driven by the sale of the Company's strategic investment in American Bitcoin Corp. shares in January 2026 for $32.4 million in cash that were valued on the books at $39.4 million based upon the trading value of such shares at year end 2025. Note that the Company's investment totaled just $100. Net loss to common stockholders of $57.4 million, an increase of $24.9 million compared to a net loss of $32.5 million in 2024. This increased net loss to common stockholders reflects the above noted one-time expenses in the quarter along with $12.9 million of tax expense recognized in Q1 2026 against no tax provision for the comparable quarter in 2025. Excluding the $19.3 million non-cash stock-based compensation, the non-GAAP adjusted net loss to common stockholders was $38.1 million in the quarter. In May 2026, the Company declared a $9.0 million dividend to be paid on or about May 29, 2026, to shareholders of record on May 15, 2026, continuing the Company's continued commitment to reward its shareholder base. As of March 31, 2026, the Company's liquid assets (defined as: "cash, marketable securities, securities owned and receivable from clearing brokers") totaled $67.4 million at the end of Q1 2026, working capital totaled $21.9 million, total assets were $85.3 million and total stockholders' equity was $31.6 million.
