Tuesday's Pre-Market Earnings

Tuesday, August 4, brings a crowded pre-market earnings slate that spans drugmakers, industrial leaders, restaurants, utilities, and energy companies. For investors following Patriot Market Research, the hard part is separating the few reports likely to move broad sectors from a long list of company-specific releases.

Pfizer, Merck, Caterpillar, McDonald's, BP, Duke Energy, and Energy Transfer are among the names set to report before regular U.S. trading begins. Earnings calendars can change, so confirm the release and call times on each company's investor relations page before acting on a calendar listing.

Key Takeaways

• Pfizer and Merck are confirmed August 4 morning reporters, putting pharmaceutical sales, drug pipelines, and 2026 guidance in focus.

• Caterpillar, McDonald's, BP, Duke Energy, and Energy Transfer bring industrial, consumer, utility, and energy signals before the bell.

• The broader calendar includes roughly 210 scheduled reports across large-cap, mid-cap, and smaller companies.

• Timken plans to release results before the NYSE opens, then host its investor call at 11:00 a.m. Eastern Time.

• Confirm whether a company reports BMO or AMC, because calendar timing labels can differ across sources.

Major Earnings Reports Scheduled Before the Market Opens on Tuesday, August 4

“BMO," "pre-market," and "before the open" all describe earnings released before the 9:30 a.m. Eastern Time start of regular NYSE and Nasdaq trading. That timing gives investors an early read on results, but it can also produce sharp moves when pre-market trading volume is thin.

The leading morning names include Pfizer (PFE), Merck (MRK), Caterpillar (CAT), McDonald's (MCD), BP (BP), Duke Energy (DUK), and Energy Transfer (ET). Duke's utility peers, including PSEG (PEG) and Pinnacle West (PNW), also appear on the schedule.

The full calendar is much larger than those headline names. Release times can vary between financial calendars, so an "expected" designation should never replace a company's own announcement.

Pfizer, Merck, and other health care companies bring major drug news

Pfizer has confirmed that it will issue its second-quarter 2026 performance report on August 4, followed by a 10:00 a.m. Eastern Time webcast. Analysts expect about $0.68 in earnings per share and revenue near $14.4 billion. The EPS comparison is important because Pfizer earned $0.78 in the prior-year period.

Investors will look beyond the headline result. Product sales, the durability of COVID-related revenue, oncology progress, new approvals, and management's full-year outlook can move the stock more than a narrow earnings beat.

Merck is also expected to report before the open, with a 9:00 a.m. Eastern Time conference call. Consensus calls for about $2.10 per share, versus $2.13 in the comparable period last year. Keytruda sales, pipeline milestones, and pricing or patent-risk commentary will draw close attention.

Revvity (RVTY), BioNTech (BNTX), Arvinas (ARVN), Certara (CERT), and Viemed Healthcare (VMD) add more health care reports to the morning list. These stocks can react strongly to clinical updates, reimbursement news, cash runway details, and a change in commercial guidance.

Caterpillar, McDonald's, BP, and Duke Energy show the market's broad reach

Caterpillar's expected EPS of about $6.20 puts heavy-equipment demand at center stage. Dealers' inventory levels, construction activity, mining orders, and the company's outlook for China can shape the market's read on global industrial activity.

McDonald's enters the morning with an estimated $3.32 per share. Comparable sales, U.S. restaurant traffic, franchisee economics, and food and labor costs matter more than a single quarterly figure. A gain in sales driven only by menu pricing may land differently than gains supported by customer visits.

For energy, BP's estimated EPS is about $1.78, while Duke Energy's estimate is near $1.31. BP's release can offer clues about refining margins, production, oil and gas prices, and capital spending. Duke's report will turn attention to power demand, rate recovery, storm costs, and its capital plan.

A company can beat consensus earnings and still fall if its outlook weakens. Guidance often sets the direction after the opening bell.

Patriot Market Research view: the wider pre-market earnings list by sector

The Patriot Market Research calendar shows why Tuesday could produce more than a few isolated stock moves. One source lists roughly 210 reports for the day, although not every company has the same confirmed timing or market impact.

Industrials and technology include Timken (TKR), Cummins (CMI), Rockwell Automation (ROK), Gartner (IT), Zebra Technologies (ZBRA), Waters (WAT), Tower Semiconductor (TSEM), IPG Photonics (IPGP), and Wix (WIX). Their results can touch factory demand, enterprise software budgets, automation spending, chip demand, and cloud-based business activity.

Consumer and food names include Sysco (SYY), Kimberly-Clark (KMB), Archer-Daniels-Midland (ADM), Ball (BALL), Coca-Cola Europacific Partners (CCEP), and Spotify (SPOT). Watch volumes, pricing, input costs, advertising, subscriptions, and retailer inventory trends.

Financial and real estate reports include Apollo Global Management (APO), Ares Commercial Real Estate (ACRE), Kimco Realty (KIM), NexPoint Residential Trust (NXRT), and TPG (TPG). Credit quality, fundraising, investment gains, property occupancy, and financing costs are likely topics.

Energy and materials names include Energy Transfer, Marathon Petroleum (MPC), MPLX, NRG Energy (NRG), Westlake (WLK), and DuPont (DD). Pipeline volumes, refinery margins, electricity demand, chemical pricing, and cash returns can drive their market reactions.

Timken gives investors a clear example of the morning schedule

Timken has said it plans to release second-quarter 2026 results before the New York Stock Exchange opens on Tuesday, August 4. The company then plans an investor conference call at 11:00 a.m. Eastern Time.

Timken's report offers a useful reminder: an earnings release and the management call aren't the same event. The written results may prompt the first stock move, while the call can alter that reaction after executives discuss orders, margins, and the outlook. Check Timken's investor relations site for the final webcast access details.

Small and mid-cap reports can add hidden market-moving news

Large companies attract most headlines, yet thinner-traded stocks can swing harder after an unexpected release. DigitalOcean (DOCN), Clearwater Analytics (CWAN), Certara, Upstart (UPST), and Zscaler (ZS) are the types of growth-oriented names investors may monitor closely when their results appear on nearby earnings calendars.

Before reacting to a headline, check the company's average trading volume, analyst coverage, revenue growth, cash flow, and debt position. A small number of shares traded before 9:30 a.m. can make an early move look more decisive than it is.

Contract announcements and revised guidance also matter. For smaller companies, one customer win or a softer forecast can outweigh an EPS beat.

How to read Tuesday's earnings calendar without mixing up report times

A BMO report arrives before regular trading. An AMC, or after-close, report arrives after the 4:00 p.m. Eastern Time closing bell. The distinction matters because it changes when investors can read the release and hear management's conference call.

Some calendars attach different timing labels to the same company. AMD, for example, appears on several August 4 earnings calendars, while other listings place its release after the close. Don't assume a date alone tells you when the numbers will arrive.

For every report on the Patriot Market Research list, confirm five details: the official release time, the fiscal quarter being reported, the EPS estimate, the revenue estimate, and the prior-year comparison. The correct fiscal period is especially important for companies whose quarters don't match the calendar.

The numbers that matter beyond beating or missing EPS

Adjusted EPS is only one line in the report. Revenue shows whether demand met expectations, while operating margin can reveal how well a company controlled costs. Free cash flow matters because it shows the cash left after operating needs and capital investment.

Also read segment results and management commentary. Caterpillar can post solid total earnings while one equipment category weakens. Pfizer may meet estimates while a major drug's sales disappoint. Conversely, a company can miss EPS but rise if investors had feared a worse result and management maintains guidance.

What to check before the opening bell

Use a short routine before placing a trade around earnings:

• Confirm the official release time through the company's investor relations page.

• Compare consensus EPS and revenue estimates with the prior year's results.

• Check pre-market price action, but treat early moves with caution.

• Read the earnings release and investor presentation before relying on headlines.

• Listen to the conference call for guidance, segment trends, and management's answers.

• Remember that earnings reactions can reverse during regular trading.

Earnings reports can create substantial volatility.

Keep the Focus on Guidance and Final Timing

Pfizer, Merck, Caterpillar, McDonald's, BP, Duke Energy, Energy Transfer, and Timken give Tuesday's pre-market schedule its broad market appeal. The wider list adds technology, health care, consumer goods, energy, finance, real estate, and industrial exposure.

The first price move may grab attention, but company guidance usually provides the better read on what investors expect next. Verify the final release time, webcast details, and outlook through official investor relations pages before trading.
