Thumzup Media Corporation Issues Shareholder Letter Highlighting Strategic Transformation into a Crypto Industry Leader

• Successfully completed a $50 million all-common stock offering at $10 per share, significantly bolstering the balance sheet to fuel aggressive expansion in mining infrastructure and substantial digital asset accumulation
• Pending acquisition of DogeHash Technologies poised to establish a premier, publicly traded, utility-scale Dogecoin mining enterprise
• Ambitious vision to dominate as North America's leading Dogecoin miner, driving unparalleled scale and innovation

LOS ANGELES, Sept. 4, 2025 /PRNewswire/ -- Thumzup Media Corporation ("Thumzup" or the "Company") (Nasdaq: TZUP), today issued a shareholder letter outlining its strategic transformation into a leader in cryptocurrency mining, supported by a pending acquisition of DogeHash Technologies, Inc. ("DogeHash"), a dedicated Dogecoin mining company.

Dear Fellow Shareholders,

Thank you for your continued support for Thumzup and our shared vision to build a transformative, billion-dollar enterprise.

Thumzup Media listed on Nasdaq last October with an upsized $8.2 million offering at $5 per share, poised to dominate, disrupt, and redefine the social media marketing landscape. We had engineered a groundbreaking platform that empowers content creators on Instagram, and soon TikTok, to earn direct payments from advertisers for authentic, positive endorsements of their products. Building on this momentum, our board of directors authorized us to buy and hold Bitcoin as a treasury asset. We invested an initial $1 million in Bitcoin (BTC) in January 2025. The positive investor response validated our vision and rewarded our BTC Allocation Strategy.

Following this positive shareholder reaction, we intensified our strategy, authorizing further investments in select cryptocurrencies. In late January, we invested another $1 million in Bitcoin. This was followed by a $6.5 million raise at $6 per share in June 2025 from strategic investors. This transaction not only fortified our cap table but also forged a pivotal relationship with Dominari Securities, a powerhouse investment bank with deep expertise and networks in the cryptocurrency ecosystem. It also brought in key strategic investors to the Company's shareholder base. In early August 2025 we closed a $50 million all common stock offering through Dominari Securities at $10 per share.  This influx of healthy capital further strengthened our balance sheet and positioned us for a transformative launch into the cryptocurrency space.

On August 19^th, we announced the execution of definitive agreements that are subject to shareholder approval to acquire a premier Dogecoin mining operation currently mining with 2,500 state-of-the-art mining rigs, with another 1,000 best in class miners ordered, that should be delivered later this year. With substantial high-margin revenues, this transaction places Thumzup on an accelerated, high-confidence trajectory to significant shareholder value creation, and could likely surpass the potential of our original digital advertising platform with reduced need for outside capital.

With capital from our recent offering, we expect to further expand this fleet, with the goal of materially increasing our revenue run-rate into 2026 and beyond. According to Bitmain, as an example, Antminer L9s (which are similar to the miners Dogehash utilizes but are not identical) have a hash rate of 16 GH/s (Gigahash) consuming 3,360W of power (Crypto Miner)_. As an illustrative example, Bitmain's mining calculator estimates 3,500 of these miners could generate high-margin annual revenues of the following at these Dogecoin prices (Bitmain):

• $0.22/DOGE: $22.70 million (current market price)
• $0.30/DOGE: $30.96 million
• $0.40/DOGE: $41.28 million
• $0.50/DOGE: $51.60 million
• $1.00/DOGE: $103.19 million

Actual results may vary, and this estimate is as of September 2, 2025. This pending acquisition marks the Company's entry into the rapidly growing $10.5 billion cryptocurrency mining market, which is projected to reach $22.6 billion by 2035, which is an 8.9% CAGR, according to Business Research Insights. Importantly, it should diversify our revenue streams while positioning us as one of the few publicly traded, utility-scale Dogecoin miners.

Cryptocurrency Mining: Seizing a Massive Opportunity

Cryptocurrency mining presents what could be one of the greatest opportunities for value creation in the industry. In December 2024, BIT Mining Limited, a publicly traded cryptocurrency miner, reported that its Dogecoin mining operations were nearly three times more profitable than Bitcoin mining alone.

Dogecoin, with a market capitalization exceeding $36 billion and daily trading volume of $4 billion as of August 13, 2025 (CoinMarketCap). It is one of the most widely held cryptocurrencies and is now held in more than 5 million wallets (Bitcoinist).

In January 2025, President Donald Trump signed an executive order strengthening America's leadership in digital financial technology, established a strategic Bitcoin reserve, and advanced the Genius Act, all of which have accelerated institutional and global confidence in cryptocurrency.

Further, there are now more than 40 publicly traded cryptocurrency mining operators with the top three reaching multi-billion-dollar valuations. MARA Holdings is the leader with a current $5.6 billion market capitalization, CleanSpark with a $4.5 billion market capitalization, and Riot Platforms with a $3 billion market capitalization.

In recent months, more than 100 public companies have adopted, "Digital Asset Treasury Strategies," putting billions of dollars of cryptocurrency on their balance sheets. Several of these companies are holding cryptocurrency, and we believe that positioning Thumzup at the nexus of both mining and holding various cryptocurrencies is our pathway to potentially becoming the next multi-billion-dollar play in this space.

Companies such as Bitmine Immersion Technologies have gone from relative obscurity to multi-billion-dollar market capitalizations in a matter of weeks. We believe Thumzup is uniquely positioned to capture similar momentum, combining the scale of our planned Dogecoin mining operations with digital asset treasury strategies.

To further support our rapid growth, we expanded our partnership with Coinbase Prime in May 2025, establishing a Bitcoin-backed credit facility and gaining access to institutional-grade trading, financing, and custody services. This strengthens our ability to scale efficiently while pursuing a diversified digital asset treasury strategy. In addition to Bitcoin, our Board has authorized holding Dogecoin (DOGE), Litecoin (LTC), Solana (SOL), Ripple (XRP), Ether (ETH), and USD Coin (USDC).

We recently created a crypto advisory board and appointed Alex Hoffman as its first member. Hoffman currently serves as head of ecosystem at DogeOS, the Dogecoin app layer, where he leads ecosystem development, partnerships and growth strategy. His expertise focuses on helping holders and companies put their Dogecoin to work through lending, staking and other applications that generate yield and expand utility. We expect to add other members to the Advisory Board in the near future.

AdTech Platform: Steady Growth, Untapped Potential
In parallel to our crypto initiatives, Thumzup's AdTech platform continues to gain traction. By August 2025, we had surpassed 34,000 social media posts approved and paid, and achieved more than 1,000 advertiser locations, validating the long-term potential of our social media marketing business, which empowers businesses to harness authentic, user-generated content. We are actively exploring tiered service packages and premium analytics subscriptions and strategic alternatives to add shareholder value and diversify revenue and drive cashflows.

Looking Ahead: A Vision for 2025 and Beyond

The Company is executing a strategy poised to disrupt cryptocurrency mining through three pillars:

1. Expansion: Scaling our mining operations with cutting edge infrastructure and treasury strategy with additional positions.
2. Innovation: Pioneering new monetization models and leveraging blockchain technology.
3. Operational Excellence: Driving cost efficiencies and profitability without compromising our bold vision.

Our Nasdaq listing not only amplifies Thumzup's visibility but also provides access to institutional and sophisticated investors, providing us with a strong foundation to pursue and execute our ambitious objectives. This positioning is especially powerful against the backdrop of an evolving U.S. regulatory and policy environment regarding cryptocurrency.

We currently maintain a balance sheet with more than $50 million in cash and relatively small burn rate. We have entered into definitive agreements, subject to shareholder approval, for an acquisition that will initially add 2,500 Doge mining rigs to our business, with an additional 1,000 mining rigs, for a total of 3,500 mining rigs. We believe this should generate a material amount of high margin revenue for the combined companies. With the capital we already have, we believe we will be able to grow that business and drive significant value for our shareholders.

In closing, the cryptocurrency industry is experiencing an unprecedented influx of investor capital and investor awareness, fueled by increasingly favorable U.S. policy. President Trump has made clear his commitment to making the United States the "crypto capital of the world" and we are determined to be part of that vision. Keep a close eye on further developments from the Company as we forge into this new and exciting industry. 

The Company is charging toward a future defined by innovation, scalability, and market leadership. Thank you for your trust and partnership as we execute our vision for 2025 and beyond.

Sincerely,
/s/ Robert Steele
