In business, H1 refers to the first half of a company’s fiscal year: a continuous six-month stretch used as a shorthand for mid-year performance, planning, and reporting. For companies on the calendar year, H1 runs from January 1 through June 30. Its counterpart, H2, covers the second half.
What H1 Covers and When It Starts
For most companies, H1 lines up with the first six months of the calendar year. It includes winter slowdowns, spring ramps, tax season, and the operational rhythms that play out between January and the end of June. When someone at a publicly traded company mentions “H1 revenue,” they mean everything the business brought in during that window.
Not every company uses the calendar year as its fiscal year. Retailers often start their fiscal year in February, after the holiday return season winds down. The federal government’s fiscal year begins in October. When a company runs on a non-standard fiscal year, H1 still means the first six months of that cycle, just shifted. A company whose fiscal year starts in October has an H1 that runs from October through March. Before assuming H1 means January through June, check the company’s fiscal year-end.
How H1 Relates to Quarters
H1 is Q1 and Q2 combined. Each quarter covers three months, so the half-year bundles six months of data into one snapshot. Individual quarters can be noisy. A company might post a weak Q1 because of weather disruptions or a delayed product launch, then bounce back in Q2. Looking at H1 as a whole smooths those short-term swings and gives a cleaner read on whether the business is trending up or down.
Analysts often prefer the half-year view for businesses with strong seasonal patterns. A ski resort’s Q1 revenue will always dwarf its Q2, but the combined H1 figure shows whether the winter-spring season performed better or worse than the year before.
How Companies Use H1 in Practice
The H1 label shows up throughout internal operations, not only in financial reports. Sales teams set H1 quotas and pipeline targets. Marketing departments build H1 campaign calendars, often treating the first half as a distinct planning cycle with its own budget, KPIs, and priorities. By June, most teams are running H1 retrospectives to figure out what worked and how to adjust for H2.
Budgeting is where H1 thinking shapes decisions most visibly. Many companies allocate annual budgets in two tranches: an H1 budget approved before the fiscal year starts, and an H2 budget adjusted at midyear based on actual H1 results. If H1 revenue comes in below forecast, the H2 budget might get trimmed. If H1 beats expectations, leadership might greenlight additional hiring or project spending. This two-phase approach gives companies a natural checkpoint to course-correct without waiting for the full year.
Hiring follows a similar rhythm. Many companies front-load recruitment in H1 so new employees are onboarded and productive before the second half. Technology firms and consultancies are especially prone to this pattern, since H1 hires can contribute to H2 revenue targets.
Measuring H1 Performance
Two comparison methods dominate H1 analysis. The most common is year-over-year: measure this year’s H1 against last year’s H1. Take the current H1 value, divide it by the prior year’s H1 value, subtract one, and multiply by 100 for a percentage. H1 2026 revenue of $12 million against H1 2025 revenue of $10 million is 20% year-over-year growth.
Year-over-year is preferred over sequential comparison (H1 against the immediately preceding H2) because it accounts for seasonality. Comparing January-through-June performance against a holiday-fueled July-through-December period would make almost any retailer look like it was shrinking, even if the business was healthy.
Sequential half-over-half comparison still has its place. Fast-growing startups and companies in turnaround situations sometimes use it to show momentum from one half to the next, since waiting a full year for a comparison point can feel too slow when things are moving quickly.
H1 and SEC Reporting
The Securities Exchange Act of 1934 requires publicly traded companies to file periodic financial reports. Under 15 U.S.C. ยง 78m, every company with registered securities must submit annual reports on Form 10-K and quarterly reports on Form 10-Q.1Office of the Law Revision Counsel. 15 USC 78m – Periodical and Other Reports The SEC does not currently require a specific “H1 report” from domestic companies. Instead, the second quarterly 10-Q filing effectively marks the end of H1, giving investors a cumulative view of the first six months.
Filing deadlines for Form 10-Q depend on the company’s size. Large accelerated filers and accelerated filers must submit their 10-Q within 40 days after the quarter ends; smaller companies get 45 days.2U.S. Securities and Exchange Commission. Form 10-Q For a calendar-year company, the Q2 report covering the end of H1 is typically due in mid-August.
Foreign companies listed on U.S. exchanges follow a different path. They file interim results on Form 6-K, which must be submitted promptly after the information is made public in their home country.3U.S. Securities and Exchange Commission. Form 6-K Many foreign issuers report on a semi-annual basis under their domestic rules, making Form 6-K the closest thing to a true H1 filing in the SEC’s system.
A Proposed Semi-Annual Option
The SEC proposed in 2026 to let public companies choose semi-annual reporting as an alternative to quarterly reports. Companies that opt in would file a new Form 10-S at midyear and a Form 10-K at year-end, replacing the three quarterly 10-Q filings.4U.S. Securities and Exchange Commission. SEC Proposes Amendments to Permit Optional Semiannual Reporting for Public Companies If adopted, that would create an official H1 filing for the first time in U.S. securities regulation. The proposal is still in the comment period and hasn’t been finalized.
H1 Is Not H-1B
Searches for “H1” frequently pull up results for the H-1B visa, which is unrelated. The H-1B is a nonimmigrant work visa allowing U.S. employers to temporarily hire foreign workers in specialty occupations requiring at least a bachelor’s degree in a relevant field.5U.S. Citizenship and Immigration Services. 7.5 H-1B Specialty Occupations If you’re reading about a company’s H1 results or H1 outlook, that’s the fiscal half-year. If you’re reading about H-1B sponsorship or H-1B cap season, that’s the work visa. The hyphen and the “B” are the tell.
