5 High-Yield Dividend Growth Stocks to Buy in August 2025 for Long-Term Wealth Building

In an era where market volatility and inflation have eroded investor confidence, the search for reliable income streams has never been more urgent. For those seeking long-term wealth building, high-yield dividend growth stocks offer a compelling solution—combining the stability of regular income with the potential for capital appreciation. The key lies in identifying companies with resilient cash flows, strategic growth catalysts, and insider buying activity, which often signal undervaluation and management confidence. Below, we analyze five such stocks that stand out in August 2025.

1. Enterprise Products Partners (EPD): Energy's Steady Giant

Dividend Yield: 6.8%
Insider Buying: $1M in share purchases by directors since resuming activity after a year-long hiatus.

Enterprise Products Partners (EPD) is a cornerstone of the midstream energy sector, operating a vast network of pipelines, storage, and processing facilities. Its fee-based revenue model generates predictable cash flows, with 85% of earnings tied to long-term contracts. In Q2 2025, EPD reported $1.9 billion in distributable cash flow (DCF), up 7% year-over-year, while allocating $4–4.5 billion to Permian Basin expansions and NGL infrastructure.

The company's 6.8% yield is among the highest in the S&P 500, supported by a 57% payout ratio and an investment-grade balance sheet. Insiders' recent purchases—despite the stock trading 10% below its 52-week high—underscore confidence in its undervaluation. With U.S. hydrocarbon demand on the rise and a $5.1 billion liquidity buffer, EPD is poised to deliver compounding returns for income-focused investors.

2. Eli Lilly (LLY): Pharma's Resilient Innovator

Dividend Yield: <1% (but consistent growth)
Insider Buying: $4M in purchases by executives and directors, including the CFO.

Eli Lilly (LLY) has faced headwinds in 2025, with a 27% drop in its stock price following a missed earnings target and disappointing clinical trials for its weight-loss drug, orforglipron. Yet, insiders have aggressively bought shares, with the CFO's purchases—historically correlated with positive earnings surprises—highlighting confidence in the company's long-term potential.

LLY's consistent dividend growth reflects its robust cash flow and diverse therapeutic pipeline. Despite short-term setbacks, its leadership in diabetes and oncology, coupled with a $40 billion R&D budget, positions it for recovery. The company's insider buying suggests a belief in its ability to navigate regulatory and competitive challenges, making it a high-conviction buy for those with a multi-year horizon.

3. Brookfield Infrastructure Partners (BIP): Global Infrastructure's Steady Hand

Dividend Yield: 4.8%
Strategic Catalysts: $9B acquisition of Colonial Pipeline and $1.5B in new capital projects.

Brookfield Infrastructure Partners (BIP) operates in a sector where demand is inelastic and growth is structural. With a 4.8% yield and a 53% payout ratio, BIP balances shareholder returns with reinvestment. Its recent $9 billion acquisition of the Colonial Pipeline—a critical artery for U.S. fuel distribution—alongside new projects in water utilities and toll roads, positions it to benefit from global infrastructure modernization.

BIP's $5.7 billion liquidity and inflation-linked contracts provide downside protection. While insider activity isn't explicitly highlighted, the company's historical performance—57.14% positive returns over three days post-earnings—suggests strong institutional confidence. For investors seeking exposure to urbanization and decarbonization trends, BIP is a compelling choice.

4. Clearway Energy (CWR): Renewable Energy's Rising Star

Dividend Yield: 3.8%
Growth Catalysts: $122M acquisition of Catalina Solar and a 291 MW storage portfolio.

Clearway Energy (CWR) is a leader in the clean energy transition, with a 3.8% yield and a 1.6x CAFD-to-dividend ratio. The company's Q2 2025 results included $152 million in cash available for distribution (CAFD), with a 1.6% dividend increase. Recent acquisitions, such as Catalina Solar and a 291 MW storage project, align with decarbonization trends and provide a scalable platform for growth.

CWR's $1.298 billion liquidity and $512 million revolver availability give it flexibility to fund its 12 GW gross capacity. With a target of $2.50–2.70 CAFD/share by 2027, the company is well-positioned to capitalize on the global shift toward renewables. For investors seeking both income and ESG alignment, CWR offers a rare combination.

5. RPM International (RPM): Industrial's Quiet Powerhouse

Dividend History: 51 consecutive years of increases.
Strategic Catalysts: Organic growth and acquisitions in construction and industrial coatings.

RPM International (RPM) is a chemical products manufacturer with a 51-year dividend growth streak. In Q2 2025, the company reported $2.08 billion in revenue, with organic growth of 6.7% in its Construction Products Group. Its recent acquisition of Artisan Design Group—a $1.325 billion deal—expands its Pro offerings in a $50 billion market.

RPM's strong balance sheet and diversified product portfolio provide resilience. While its yield isn't specified, its long-term dividend growth and exposure to industrial and construction demand make it a defensive play in a volatile market.

Final Thoughts: Building a Dividend-Driven Portfolio

The five stocks above—EPD, LLY, BIP, CWR, and RPM—represent a diversified mix of high-yield, growth-oriented opportunities. Each combines resilient cash flows, strategic reinvestment, and insider confidence to create a compelling case for long-term wealth building.

For investors, the key is to balance income with growth potential. EPD and LLY offer immediate yield and recovery narratives, while BIP and CWR align with macroeconomic trends like infrastructure and decarbonization. RPM, with its industrial exposure, provides a defensive anchor.
