The week of August 4, 2025, kicks off with an unusually high concentration of major earnings reports, spanning blue-chip conglomerates, high-growth tech, biotech innovators, and next-gen semiconductor firms. Among the most anticipated names reporting on Monday are Berkshire Hathaway, Palantir, Wayfair, BioNTech, Onsemi, Mercado Libre, Axon, Hims & Hers, Axsome Therapeutics, and Navitas. With several reports scheduled before market open and others after the close, investors are bracing for a potentially volatile trading session that could shape sentiment for the rest of the week.

Berkshire Hathaway: Buffett’s Barometer for the U.S. Economy

Before markets open, Berkshire Hathaway (BRK.B) will publish its Q2 earnings, an event closely watched by institutional and retail investors alike. Under the stewardship of Warren Buffett, Berkshire’s performance is often seen as a proxy for the health of the broader U.S. economy. The firm holds vast interests across insurance, railroads, utilities, banking, and consumer staples, with a cash reserve north of $189 billion as of last quarter. Analysts will be keen to see whether Berkshire engaged in any new acquisitions or stock buybacks, which amounted to $2.6 billion last quarter.

Beyond its operating businesses, investors will scrutinize gains or losses in Berkshire’s massive equity portfolio, which includes large stakes in Apple, Occidental Petroleum, and American Express. With BRK.B stock up about 22% over the past year, any deviation in earnings or commentary from Buffett could ripple across markets.

Wayfair: Struggling E-Commerce Giant Seeks Stability

Wayfair (W) is also reporting pre-market and remains under pressure following years of post-pandemic deceleration. After peaking in 2021, the online home goods retailer has faced rising shipping costs, supply chain headwinds, and mounting competition from Amazon and Walmart. The Street expects revenue of approximately $3 billion for the quarter, with a net loss around $0.80 per share—slightly improved from a $1.27 loss a year ago.

Despite recent efforts to streamline operations and trim costs, Wayfair’s core challenge remains reigniting top-line growth while preserving margins. Monday’s report may be pivotal in restoring investor confidence, particularly if active customer counts and order values show signs of stabilization.

BioNTech: From Pandemic Darling to Oncology Challenger

Once at the center of the global vaccine response, BioNTech (BNTX) now faces the daunting task of reinventing itself. Analysts project a dramatic decline in revenue—down from $3.2 billion a year ago to just around $600 million this quarter—as COVID-19 vaccine sales continue to plummet. The company’s future now hinges on its oncology pipeline, where it’s developing mRNA-based therapies for various cancers.

Investors will pay close attention to R&D spending and any updates on clinical trial progress. Despite its significant cash reserves, the stock has fallen roughly 17% YTD, reflecting skepticism about the company’s ability to transition from pandemic-era windfalls to sustainable innovation.

Onsemi: EV Momentum Faces Semiconductor Headwinds

Onsemi (ON), reporting before the bell, has been one of the strongest semiconductor plays in the automotive and industrial sectors. The company has shown consistent growth in demand for silicon carbide (SiC) chips used in electric vehicles, autonomous systems, and power grids. However, macroeconomic uncertainty and broader industry softness are beginning to weigh.

Consensus estimates call for Q2 revenue of about $2.02 billion and earnings per share of $1.26—down from the prior quarter but up year-over-year. Investors will be looking for signals that automotive demand remains intact while assessing margin pressure from raw material costs and supply chain bottlenecks.

Axsome Therapeutics: Psyched for a Breakthrough

Axsome Therapeutics (AXSM), a neuro-focused biotech, has garnered attention thanks to its portfolio targeting major depressive disorder and narcolepsy. Key assets include Auvelity and Sunosi, which posted a combined revenue growth of 47% last quarter. Analysts are hoping for more details on regulatory paths for AXS-05, the company’s most promising drug candidate.

Despite steady revenue growth, Axsome remains unprofitable. Investors will want clarity on timelines for potential FDA approvals and whether the company’s R&D spending remains manageable without additional capital raises. The stock is trading near support levels and could swing sharply on any guidance surprises.

Navitas Semiconductor: GaN Tech Meets Market Reality

Navitas (NVTS), a GaN-based semiconductor innovator, reports after the close and will be under the microscope after an 80% rally YTD. The company is positioning itself at the forefront of high-efficiency, low-heat power solutions used in data centers, fast chargers, and EVs. Analysts expect Q2 revenue of approximately $28–30 million, representing over 35% YoY growth.

However, the company is still operating at a net loss, and its cash burn is a concern. Investors will look for signs of operational leverage and progress in securing Tier 1 customers. If growth continues at current rates but losses remain elevated, sentiment could turn quickly.

Palantir: Riding the AI Defense Wave

Palantir Technologies (PLTR) has become a poster child for applied AI in defense and enterprise. After delivering $634 million in revenue last quarter with $0.08 in EPS, the company is expected to report roughly $760 million in Q2 revenue, marking 20% YoY growth. Key drivers include renewed government contracts and growing commercial adoption of its Foundry and Gotham platforms.

However, with the stock having risen over 140% YTD, expectations are sky-high. Even a slight miss on forward guidance or bookings could trigger volatility. Investors will be watching closely for updates on AI partnerships and any commentary on Palantir’s expanding enterprise footprint.

Hims & Hers: Digitizing Personal Health

Hims & Hers (HIMS), the digital health startup catering to Millennials and Gen Z, reports after market close. Its model centers on accessible, discreet treatment for dermatology, mental health, and wellness conditions. Q2 revenue is projected around $270 million—up 60% YoY.

Despite explosive top-line growth, the company has yet to achieve profitability. Investors will focus on gross margin expansion and efforts to reduce net losses. User retention, subscription growth, and new product offerings will also be key themes on the call.

Mercado Libre & Axon: Regional and Tactical Growth Stories

Mercado Libre (MELI), the dominant e-commerce and fintech player in Latin America, continues to impress despite currency volatility and macro risks. Analysts expect revenue north of $4.5 billion and EPS of $7.60—up more than 25% YoY. The company’s strength in logistics, payments, and credit services has made it one of the region’s most resilient tech firms.

Axon Enterprise (AXON), best known for its TASERs and body cameras, is quietly evolving into a SaaS-driven law enforcement platform. The company is benefiting from strong demand in North America and is expanding its AI-based evidence and analytics tools. Investors expect solid bookings growth and commentary on margin stability.

Strategic Overview and Broader Market Implications

Monday’s earnings releases span nearly every major sector—industrials, tech, biotech, e-commerce, and AI—and thus offer a comprehensive pulse on the market’s health. From Berkshire’s conservative industrial empire to Palantir’s cutting-edge AI platforms, investors will digest a flood of data points. Some firms, like Mercado Libre and Onsemi, are expected to confirm ongoing secular tailwinds, while others—like BioNTech and Wayfair—face existential business transitions.

The divergence between profitability and growth will be a central theme. Companies like Axon and Palantir are reaching scale, while firms like Hims and Navitas are betting on future monetization. Expect volatility, both on a single-stock level and sector-wide, as investors recalibrate valuations and macro outlooks based on this pivotal earnings day.
