DAN Hello, everyone. My name is Dan Kang. I’m Chief Strategy Officer and Head of Investor Relations at DeFi Development Corp, joining me today is Joseph Onorati, Chief Executive Officer and Chairman of the Board of Directors, and we’re excited to walk you through our Series C variable-rate perpetual preferred, ticker CHAD. SLIDE 2 - Forward-Looking Statements DK: Before we begin the Q&A, I would like to remind everyone that we will be making forward-looking statements during this call that involve a number of risks and uncertainties. Actual results may differ materially due to risks and uncertainties, which are outlined in our filings with the SEC, including our form 10-K and Form 10-Q. Actual results may differ materially from those expressed or implied in the forward-looking statements due to a variety of factors. These factors are described under forward-looking statements in our shareholder letter and in our most recent filings with the Securities and Exchange Commission. That being said, we urge you to consider these factors and remind you that we undertake no obligation to update the information contained in this call to reflect subsequent events or circumstances. You should be aware that these statements should be considered estimates only and are not a guarantee of future performance. For those of you who follow the space, the most comparable instrument to CHAD is SATA. CHAD is contemplated with a 13% headline dividend, paid daily, with one notable distinction being that par value will be $10 instead of $100. At the current $9 price we’re contemplating, investors are starting with an effective yield of roughly 14.4%. But the yield itself is not really the most interesting part. What we think makes CHAD different is the combination of three things. - First, it is the first Solana-backed preferred to hit the market, which means the asset underneath it is productive. In other words, the dividend can be supported by organic cash generation. - Second, we believe SOL has a higher long-term return profile than BTC, which should support both our asset base and our ability to maintain ample coverage over time. - And third, the variable-rate structure gives us a mechanism to actively support the security toward par SLIDE 4 - Contents DAN Here’s a quick look at what we will discuss. First, we’ll dive into why digital credit exists and why the category has worked. Second, why we think Solana is actually a better asset to back digital credit. Third, why DFDV is the right company to issue it. And finally, we’ll walk through the pro forma math, our pro forma coverage metrics, and our ability to get CHAD to par SLIDE 5 - Chapter 1 - The Rise of Digital Credit SLIDE 6 - Traditional credit forces investors to choose between yield, liquidity, and transparency DAN To start, I think it’s worth asking why digital credit exists at all. DAN Traditional credit has always forced investors into a tradeoff. You can get safety, you can get liquidity, or you can get a meaningful real yield, but it is very difficult to get all three.

DAN Private credit solved part of that problem by offering more yield, but it generally did that by sacrificing liquidity and transparency. You lock up your capital, the marks are not always obvious, and the product is not particularly accessible to a retail investor. SLIDE 7 - Digital credit has exploded in 2026, with Strategy’s STRC notional up 3.6x year over year [DAN] DAN Digital credit has changed that equation, and STRC is probably the clearest proof point. STRC notional has grown dramatically, the holder base is heavily retail, and the market has shown there is real demand for a liquid, exchange-traded income product sitting on top of a crypto treasury. SLIDE 8 - Digital credit has shown lower volatility than crypto, with minimal correlation to BTC [DAN] DAN What is especially interesting is how the preferred itself trades. Despite being issued by a company whose primary asset is Bitcoin, STRC has traded throughout most of its life with relatively low volatility and very little correlation to Bitcoin. DAN That sounds counterintuitive at first. You have a volatile underlying asset, yet you can create a relatively stable income instrument on top of it. SLIDE 9 - Digital credit is powered by volatile, appreciating collateral [DAN] DAN But the volatility and appreciation of BTC are actually features of the model, not bugs. Bitcoin has outperformed most traditional asset classes over long periods of time. The variable-rate preferred harvests a portion of that outperformance and turns it into relatively stable income, while dampening the volatility of the underlying. DAN So Bitcoin proved the model. The question for us was: what happens if you use an asset that has the same basic ingredients, but is also productive? SLIDE 10 - Chapter 2 - Digital Credit’s Next Evolution is on Solana [Advance.] WHY SOLANA - DK SLIDE 11 - Digital Credit works with Bitcoin. It works better with Solana [DAN] DAN So let’s talk about why we think Solana is the best asset to back digital credit. DAN This is probably the most important conceptual slide in the deck. Bitcoin and Solana are both volatile assets. We obviously believe both can appreciate materially over time. But the key difference is that Solana is productive. DAN Bitcoin does not natively generate yield. SOL does. Today, simply participating in the Solana network can generate roughly 6% native yield before you do anything more sophisticated with validators or onchain operations. And historically, our yields have generally ranged closer to 8% to 10%. DAN That is an incredibly powerful dynamic for a variable-rate preferred, because now the underlying asset is doing two jobs at once. It can appreciate and expand the treasury asset base, just like Bitcoin, but it can also generate cash flow that helps pay the dividend. DAN That is a key reason why we think CHAD is a better digital-credit instrument. Not only do we believe SOL has a higher long-term return profile, it also creates a way to cover the dividend that Bitcoin-backed issuers simply do not have in the same way. SLIDE 12 - CHAD takes the model further, pairing a 13% dividend yield with productive SOL collateral [DAN] DAN You are getting that with an effective launch yield of roughly 14.4%. That is above the effective yields shown here for STRC and SATA, while the underlying collateral itself is productive. DAN So the basic pitch is not just ‘higher yield.’ It is higher yield attached to an asset that can actually generate income to help service that yield.

SLIDE 13 - CHAD improves on the digital credit playbook with a faster path to par [DAN] DAN The next obvious question is: if par is $10, why am I buying this at $9? I think this is an extremely important part of the structure. DAN We are not launching below par and simply hoping the market eventually closes the discount, or that SOL price appreciation alone gets us there, although that obviously could help. DAN CHAD, like STRC and SATA, has a variable-rate dividend. Our goal is to get CHAD to par fast, and the variable-rate mechanism gives us a tool to support that outcome. DAN STRC took roughly 99 calendar days to reach par. SATA took roughly 72, in part because it started with a higher yield and was able to follow the STRC playbook. We want to take the learnings from both and try to get CHAD there even faster. DAN We obviously cannot guarantee the same path, and the CHAD line on this chart is illustrative, not a forecast. But STRC and SATA show that the mechanism can work. By starting around SATA’s headline yield, paying dividends daily, and having cash flows that can actually cover the dividend, we think we are starting from a very strong position. SLIDE 14 - Bitcoin is digital capital; Solana is digital energy [DAN] DAN I’d like to spend a few minutes on why we have so much conviction in Solana itself. DAN For those who are newer to crypto, the simplest way I compare Bitcoin and Solana is this: Bitcoin stores value. Solana moves it. Bitcoin is digital capital. Solana is much closer to digital energy. DAN It is a high-throughput network designed to process transactions, stablecoin flows, tokenized securities, consumer applications, and machine-to-machine commerce. And that distinction creates something Bitcoin does not have to the same degree: secular demand tied to actual economic activity. DAN Solana is effectively a bet on crypto utility. We could spend hours talking about why we think it is the best bet on crypto utility, but the short version is: it is fast, it is cheap, and it scales. SLIDE 15 - Solana’s TPS potential is on par with Visa [DAN] DAN How fast? Solana is one of the only crypto networks with the potential to process transactions at a scale comparable to, or greater than, major payment networks like Visa. SLIDE 16 - Transaction finality measured in milliseconds [DAN] DAN And speed is not just about throughput. It is also about finality. The network is moving toward transaction settlement measured in milliseconds. That matters if you want financial assets, payments, or autonomous software to actually run on these rails. SLIDE 17 - Three megatrends converging [DAN] DAN Over the next two to three years, we think Solana is positioned to benefit from three enormous megatrends: tokenization, meaning assets moving onchain; stablecoin growth; and agentic finance. SLIDE 18 - Solana has an early lead in all three onchain megatrend categories [DAN] DAN And importantly, this is not purely theoretical. Solana already has an early, and in some cases dominant, leadership position across all three. DAN It has the overwhelming share of tokenized-equity spot volume in the data shown here, the highest five-year CAGR in stablecoin TVL among major chains, and a significant share of x402 agent-to-agent payment activity. SLIDE 19 - Tokenization makes assets programmable, accessible, and easy to transfer [DAN] DAN Let’s touch briefly on the early proof points. What is tokenization? The idea is actually pretty simple. Equities, funds, private securities, Treasuries, real estate — assets that today live inside fragmented databases and a lot of expensive traditional financial infrastructure — increasingly move onto cheaper, more open, programmable rails. DAN And Solana is one of the best rails for that transition because it is fast, cheap, and capable of handling very high throughput.

SLIDE 20 - CHAD pairs digital credit with Solana’s tokenized equity leadership [DAN] DAN Today, 96% of the tokenized-equity spot volume in the data shown here has settled on Solana. DAN Why does that matter to a preferred investor? Because it means there is a secular growth vector attached directly to the asset supporting the preferred. DAN When you buy CHAD, you are not just buying a regular run-of-the-mill preferred. You are buying digital credit backed by an asset that we think can be a major beneficiary of a very large shift in financial infrastructure. That is something other digital-credit instruments simply do not have in the same way. SLIDE 21 - Stablecoins are exploding and will be a major settlement rail [DAN] DAN You see the same thing in stablecoins. Stablecoins have gone from a crypto-native product to a legitimate global settlement technology, and the market has grown dramatically. SLIDE 22 - If stablecoins are the ChatGPT of crypto, then Solana is Nvidia [DAN] DAN And Solana has become one of the fastest-growing networks for stablecoin activity. DAN The analogy I sometimes use is: if stablecoins are crypto’s ChatGPT moment, Solana has the opportunity to be one of the Nvidias — the infrastructure that is actually powering the application boom. SLIDE 23 - Early signs are promising, but agents will need a lot more SOL [DAN] DAN Lastly, although it is still early for agentic finance, the early signs for Solana are incredibly promising. DAN The idea here is that agents need to transact constantly, in tiny amounts, across borders, without waiting for banking hours or paying card-network minimums. Traditional rails were never designed for that. Blockchains were. DAN And even at this very early stage, Solana already has a significant share of x402 agent payments. DAN Do we need agentic finance to take off to pay our preferred dividends? No. The point is simply that the underlying asset on our treasury has multiple secular demand curves that we think can strengthen the asset base over time. And with that, I’d like to hand it off to Joseph to talk about DFDV and why we’re best positioned to issue CHAD.

So now that DK has laid out why we like Solana and why we think it is a compelling asset to back digital credit, let me spend a few minutes on why DFDV is the right issuer. - We were the first US- listed Solana digital asset treasury company, and the team combines deep crypto-native experience with traditional finance and public-company experience. - The people on this slide have worked across multiple crypto cycles and across firms including Kraken, Morgan Stanley, Goldman Sachs and Jefferies. - This is a team that was unusually well positioned to launch and operate a digital asset treasury, and we are proud that we were the first non-Bitcoin DAT in the U.S, and have delivered the highest equity returns of any DAT since initiation of our treasury strategy SLIDE 26 - Three ways to own SOL, but only one compounds and amplifies [JOSEPH] - But what does it actually mean to be a DAT, and why would somebody own one? - There are basically three ways for investors to own SOL. You can own spot. You can own an ETF. Or you can own an amplified expression of SOL through DFDV. - Spot gives you direct exposure. An ETF is a passive wrapper. DFDV’s job is different. We are using the power of our balance sheet, staking, validators and the capital markets to grow the amount of SOL exposure attributable to each common share over time.

- This creates amplified, or leveraged SOL exposure, without many of the near-term risks that investors are usually presented when taking on leverage on their own. SLIDE 27 - Intelligent leverage plus SPS growth equals SOL Boost [JOSEPH] - That takes us to what we call the SOL Boost framework. The concept is straightforward: you start with the return of SOL, you add the effect of intelligent leverage, and then you add SOL-per-share growth. - Those two engines — leverage and SPS growth — are how we try to turn basic SOL exposure into leveraged SOL exposure. SLIDE 28 - Intelligent leverage amplifies without liquidation risk [JOSEPH] - But it is important to distinguish between intelligent, well-structured leverage that can withstand a bear market and predatory leverage that can blow up at exactly the wrong time. - For us, good leverage is long-dated, unsecured or structurally flexible, and does not create margin calls or forced-liquidation triggers against the SOL treasury. - That is very different from short-dated secured debt, high leverage on perpetual futures, or structures that force you to sell the asset when the market is already moving against you. - CHAD, by virtue of never having its principal come due, is an example of intelligent leverage SLIDE 29 - Other amplification alternatives come with near-term liquidation risk [JOSEPH] - This next slide shows how that distinction can matter over a volatile five-year period. - And the idea is that traditional forms of leverage can create near-term liquidation risk. - If you trade on margin, or with perps, one unfavorable move in SOL in the near-term takes you to 0 - With DFDV, our capital structure is designed to survive prolonged periods of crypto volatility - For example, SOL could drop 50% tomorrow and the company would not get liquidated - This creates incredible durability in our structure, while letting us amplify the upside when the cycle turns back up. - We’ve seen this play out in the near-term, where DFDV has outperformed SOL by over 2x month to date SLIDE 30 - SOL per share growth means more exposure to SOL over time [JOSEPH] - The second component of SOL Boost is SPS growth — SOL per share — and this is our North Star. - Over the last twelve months, our SOL per share has grown roughly 24%. - That is the metric we care about because simply owning SOL is passive. Our job is to take the same underlying asset and compound it through staking, validators, onchain operations and intelligent use of the capital markets. - For common shareholders, that means more SOL per share over time. SLIDE 31 - DFDV is the #1 performing DAT stock and the only SOL DAT with positive returns post treasury launch [JOSEPH] - And the result, so far, is that since initiating our treasury strategy we have produced the strongest equity performance in the peer set shown here. - We think that reflects both the quality of the underlying asset, and the way the team has operated the balance sheet → by putting intelligent leverage in the capital structure, and putting up industry- leading SPS growth. - With that, I’ll now hand it back to DK for the part that matters most to a preferred investor: the yield engine, the coverage, and the downside cases. YIELD, COVERAGE AND DOWNSIDE PROTECTION SLIDE 32 - DFDV optimizes Solana’s native yield [DAN] DAN Thanks, Joseph. I want to go back and revisit the yield story, because this is where the preferred thesis really comes together.

DAN Today, you can earn about 5.8% through staking ETFs such as BSOL. Net of fees that’s closer to 5.6%. If you stake on coinbase, you only earn 3.4%. - DFDV has historically done better than that because we operate validators, stake directly, and deploy portions of the treasury onchain. - Historically, we have been able to generate roughly 200 to 300 basis points of yield above base staking rates, reflecting our technical expertise, knowledge of crypto, and ability to prudently manage risk. - That yield is real economic income, and the cash flow is substantial relative to the size of CHAD. SLIDE 33 - Organic coverage + a variable dividend create ample coverage and a credible path toward par [DAN] - This slide right here, really highlights the most important distinction versus other digital-credit products. - We do not want our dividend policy to be entirely dependent on the common-equity ATM. We do not want to have to issue stock every quarter simply to pay preferred holders. - In our case, the asset itself — SOL — generates income that can service CHAD. - CHAD is a high-yield preferred paid from a productive asset base. If is the ONLY high yield preferred in the digital credit space, to source dividends from a productive asset base - On the assumptions shown here, our organic yield alone covers the preferred dividend multiple times over. - That matters for the preferred holder, and it also matters for the common shareholder because we are not designing a structure where the preferred dividend automatically becomes dilution for the common. SLIDE 34 - Chapter 4 - Terms and Pro-Forma Analysis [Advance.] SLIDE 35 - CHAD is SATA backed by revenue — organic dividend coverage is our path to par - Now, a quick overview of some pro forma metrics. - On the current assumptions shown in the deck, the company generates roughly $20 million of annualized organic revenue against approximately $13 million of annual debt and preferred obligations. - And notably, we are using the lower end of our historical organic yields. There have been periods where our annualized yield was materially higher, such as Q3 when we generated yields north of 11% - Obviously, not every quarter will look exactly the same. But the point is that there is an organic earnings engine here that simply does not exist for a non-productive treasury asset. SLIDE 36 - CHAD remains well covered even if SOL falls 50% [DAN] - More importantly, the asset coverage is substantial. - At current SOL prices, our analysis shows roughly 20.3 times SOL asset coverage of annual obligations and over 10 times SOL value relative to CHAD notional. - If SOL falls 25: We still show about 15 times SOL coverage, 8 times SOL-to-CHAD coverage, and organic yield remains sufficient to cover our obligations. - In other words, under that scenario, we still do not need to rely on issuing common stock to fund the dividend. - Even if SOL falls 50%, the asset base remains very large relative to CHAD — more than five point five times CHAD notional in the current analysis. - From a digital-credit perspective, the question should not just be: ‘How much do I think SOL goes up?’ It should be: ‘How much asset value sits behind me? How much income does that asset generate? And how far can the underlying asset fall before the preferred becomes stressed?’ - At the contemplated terms, we think the coverage ratios are some of the strongest in the space. SLIDE 37 - Offering Overview [DAN] - So I’ll finish where I started. CHAD is not interesting simply because it has a high dividend. There are plenty of high-yield securities in the world, many of which involve a lot of opaque risk.

- We think CHAD is interesting because it combines a high effective starting yield with productive collateral, organic income that can service the dividend, a large asset base that remains well covered under meaningful downside scenarios, and a variable-rate mechanism that gives us a tool to support the security toward par. - And unlike most traditional preferreds — or even other digital-credit instruments — the collateral itself sits in front of secular growth from tokenization, stablecoins, and agentic finance. SLIDE 38 - DeFi Development Corp. - Crypto Born. TradFi Fueled. Built to Stack Solana. [DAN] - So the simplest way I would frame CHAD is this: digital credit already works. We think Solana makes it that much better. And we built CHAD to turn that advantage into income. DAN: Thank you. Joseph and I thank you for your time and attention today, and we look forward to speaking with you further as we bring CHAD to market.
