Thumzup Mines DogeHash: $50M Power Play

• Capital infusion secured through a $50 million stock offering, priced at $10 per share, strengthening financial position for expansion in mining infrastructure and accumulation of digital assets.
• Expected acquisition of DogeHash Technologies will establish a leading, publicly traded company focused on utility-scale Dogecoin mining.
• Aims to become the dominant Dogecoin mining operation in North America, emphasizing both scale and innovative approaches.

LOS ANGELES, Sept. 4, 2025 /PRNewswire/ — Thumzup Media Corporation (“Thumzup” or the “Company”) (Nasdaq: TZUP) shared an update to shareholders today. The letter highlighted the Company’s strategic shift towards becoming a major player in cryptocurrency mining, driven by the planned acquisition of DogeHash Technologies, Inc. (“DogeHash”), a company specializing in Dogecoin mining.

To Our Valued Shareholders,

We extend our gratitude for your ongoing support of Thumzup and our shared aspiration to create a significant enterprise.

Thumzup Media debuted on Nasdaq last October with an increased $8.2 million offering priced at $5 per share, determined to lead and transform the social media marketing sector. Our team developed an innovative platform enabling content creators on Instagram, and soon TikTok, to receive direct compensation from advertisers for genuine endorsements. Furthering this progress, the board authorized the purchase and holding of Bitcoin as a treasury asset. Our initial $1 million investment in Bitcoin (BTC) occurred in January 2025. Investor approval validated our vision, recognizing the strength of our BTC Allocation Strategy.

Building on this positive response, the company strengthened its focus, approving further investments in select cryptocurrencies. Another $1 million was invested in Bitcoin in late January. Subsequently, in June 2025, $6.5 million was raised through strategic investors at $6 per share. Beyond bolstering our financial foundation, this transaction created a key partnership with Dominari Securities, a leading investment bank with significant expertise and connections within the cryptocurrency space. This round brought in key strategic investors to the Company’s shareholder base. In early August 2025, we finalized a $50 million all common stock offering with Dominari Securities at $10 per share. This injection of capital strengthens the balance sheet and sets the stage for a major entry into the cryptocurrency sector.

On August 19^th, the company announced definitive agreements were signed, pending shareholder approval, to acquire a top-tier Dogecoin mining operation currently utilizing 2,500 advanced mining rigs, with an additional 1,000 high-performance miners on order for delivery later this year. Expected to generate substantial revenues, this acquisition puts Thumzup on a path to create significant shareholder value, potentially exceeding that of the original digital advertising platform and with a decreased need for external capital.

The raised capital will support further expansion of this mining operation, with the objective of significantly increasing revenue in 2026 and beyond. For example, Bitmain estimates that Antminer L9s (similar, but not identical, to Dogehash miners) have a hash rate of 16 GH/s (Gigahash) consuming 3,360W of power (Crypto Miner). To illustrate, Bitmain’s mining calculator estimates 3,500 of these miners could generate high-margin annual revenues at the following 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

These estimates are as of September 2, 2025, and actual figures may differ. This pending acquisition marks the Company’s entry into the fast-growing $10.5 billion cryptocurrency mining market, forecast to reach $22.6 billion by 2035, reflecting an 8.9% CAGR, according to Business Research Insights. The acquisition diversifies revenue streams while establishing Thumzup as one of the few publicly traded, utility-scale Dogecoin miners.

Cryptocurrency Mining: A Significant Opportunity

Cryptocurrency mining offers significant potential for value creation. In December 2024, BIT Mining Limited, a publicly traded cryptocurrency miner, indicated that its Dogecoin mining was nearly three times more profitable than its Bitcoin mining alone.

Dogecoin, with a market capitalization exceeding $36 billion and daily trading volume of $4 billion as of August 13, 2025 (CoinMarketCap), is a widely held cryptocurrency held in over 5 million wallets (Bitcoinist).

In January 2025, President Donald Trump signed an executive order designed to enhance America’s position in digital financial technology, create a strategic Bitcoin reserve, and push forward the Genius Act, collectively bolstering institutional and global confidence in cryptocurrency.

The landscape includes over 40 publicly traded cryptocurrency mining companies, with the top three valued in the billions. MARA Holdings currently leads with a $5.6 billion market capitalization, followed by CleanSpark at $4.5 billion, and Riot Platforms at $3 billion.

Recently, over 100 public companies have adopted “Digital Asset Treasury Strategies,” allocating billions to cryptocurrency holdings. Thumzup believes that positioning itself at the intersection of mining and holding various cryptocurrencies offers a path to becoming a multi-billion-dollar player in the sector.

Companies like Bitmine Immersion Technologies have rapidly grown from relative obscurity to multi-billion-dollar market capitalizations. Thumzup believes it is well-placed to achieve similar growth, combining planned Dogecoin mining operations with digital asset treasury strategies.

To support this rapid growth, Thumzup expanded its 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 will strengthen our ability to scale efficiently while pursuing a diversified digital asset treasury strategy. In addition to Bitcoin, the Board has authorized holding Dogecoin (DOGE), Litecoin (LTC), Solana (SOL), Ripple (XRP), Ether (ETH), and USD Coin (USDC).

A crypto advisory board was recently established, appointing Alex Hoffman as the initial member. Hoffman currently leads ecosystem development, partnerships and growth strategy at DogeOS, the Dogecoin app layer. Hoffman’s expertise centers on helping holders and companies use their Dogecoin through lending, staking, and other applications to generate yield and expand utility. Additional members are expected to be added to the advisory board soon.

AdTech Platform: Steady Expansion, Future Potential

Thumzup’s AdTech platform continues to grow alongside its crypto initiatives. By August 2025, over 34,000 social media posts had been approved and paid, with over 1,000 advertiser locations. This validates the potential of our social media marketing business, enabling businesses to leverage authentic, user-generated content. We are exploring tiered service packages and premium analytics subscriptions and strategic alternatives to add shareholder value and diversify revenue and drive cashflows.

Vision for 2025 and Beyond

The company is executing a disruptive strategy through three pillars:

1. Expansion: Scale mining operations through treasury strategy and infrastructure.
2. Innovation: Discover new ways to monetize and leverage blockchain technology.
3. Operational Excellence: Prioritize cost efficiencies while staying committed to the vision.

The Nasdaq listing enhances visibility, allowing access to institutional investors, establishing a solid base to achieve goals. This is in the context of evolving U.S. regulations related to cryptocurrency.

We have a balance sheet of over $50 million in cash and a relatively small burn rate. Agreements are in place, pending shareholder approval, for an acquisition that will bring 2,500 Doge mining rigs to our business initially, and 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 existing capital, we expect to be able to grow the business and increase value for shareholders.

Investor capital and awareness are increasing in the cryptocurrency sector, driven by favorable U.S. policy. President Trump wants to make the United States the “crypto capital of the world” and we want to be a part of it. Look for further announcements as we move into this new industry.

Thumzup is moving towards a future of innovation, scalability, and leadership. We appreciate your trust as we work to realize our vision for 2025 and beyond.

Sincerely,
/s/ Robert Steele
