CHAD brings Digital Credit 2.0 to income investors: a 13% annual dividend rate supported by a productive SOL treasury

BOCA RATON, FL - September 28, 2026 - DeFi Development Corp. (Nasdaq: DFDV) (the "Company" or "DeFi Dev Corp."), the first U.S. public company with a treasury strategy built to accumulate and compound Solana ("SOL"), today announced that it has added approximately 47,706 SOL to its treasury since September 21, 2026, bringing total holdings to approximately 2,538,010 SOL and SOL equivalents worth $309M.

The latest increase represents approximately 2% growth week over week, and brings total SOL and SOL equivalents growth to approximately 10% since the Company's Q2 earnings report on August 12. With the recently established $300 million CHAD ATM providing an additional source of growth capital, the Company believes its SOL accumulation flywheel is continuing to gain momentum.

"We are building our SOL treasury week by week, and those gains are adding up," said Joseph Onorati, Chief Executive Officer of DeFi Development Corp. "Our SOL and SOL equivalents grew another 2% last week. Since our Q2 earnings update, we have added over 226,000 SOL, expanding our treasury 10% in just six weeks. With tokenization and agentic AI opening new opportunities for Solana, we intend to keep accumulating and put those holdings to work."

Building for Tokenization and Agentic AI

DFDV believes tokenization and agentic AI represent significant potential drivers of demand for crypto, with Solana well positioned to support financial activity that requires fast settlement, low transaction costs, and around-the-clock availability.

"Tokenization brings stocks, funds, and other financial assets onchain. Agentic AI introduces software that can transact, make payments, and manage resources on its own," continued Onorati. "Both need financial infrastructure that operates at lightning speed. We believe Solana will become a core part of that infrastructure, and we intend to keep building our position as that opportunity develops."

From June 30, 2026 through September 25, 2026, SOL gained approximately 73%, outperforming the Nasdaq-100 by approximately 72 percentage points. DFDV shares gained approximately 105% over the same period, delivering approximately 1.4 times SOL's percentage return.

"This quarter's performance has been strong, but our investment thesis in Solana extends much further," said Onorati. "We see a future with trillions of dollars of assets, payments, and economic activity moving onchain, and we believe Solana will capture a meaningful share of that opportunity. Our objective is to accumulate as much SOL as we can ahead of that adoption, put it to work, and compound our holdings as the network grows."

CHAD: Bringing Digital Credit 2.0 to More Investors

Alongside continued SOL accumulation, DFDV continued expanding its efforts to build awareness, market access, and liquidity for CHAD, its Nasdaq-listed variable-rate preferred stock. CHAD currently carries a 13% annual dividend rate on its $10 stated amount, equivalent to $1.30 per share annually at the current rate, with dividends paid each business day when declared.

The Company views CHAD as Digital Credit 2.0: preferred equity supported by a productive treasury. Through staking and validator operations, DFDV's SOL holdings generate recurring rewards and fees, providing an organic source of income to support dividend obligations. Additional SOL deployed into these operations can expand the treasury's earning capacity, connecting continued accumulation with the economics supporting CHAD.

"Digital Credit 2.0 starts with a simple idea: the assets supporting the preferred should themselves be productive," said Joseph Onorati, Chief Executive Officer of DeFi Development Corp. "Our SOL treasury earns additional SOL through staking and validator operations. That gives CHAD an income-generating foundation and gives us the opportunity to grow that earning power as we accumulate more."

"CHAD brings that story to income investors through a 13% annual dividend rate and payments each business day when declared," continued Onorati. "We want to make CHAD a widely recognized name in digital credit. Expanding investor access, demonstrating dividend coverage, and supporting trading toward its $10 stated amount are priorities for us."
