What Impact Does Equity-Based Compensation Have on Reported Earnings?

📊 ⚖️

Equity-based compensation — stock options, RSUs, PSUs, and similar awards — is one of the most consequential and most debated items on corporate income statements. Under both US GAAP (ASC 718) and IFRS 2, it reduces reported net income, lowers diluted earnings per share, and triggers a long-running argument about what earnings actually mean. Here is a plain-language guide to every mechanism, with verified data, accounting standards references, and what investors need to watch for.

📉 S&P 500 SBC Total

$192B in 2022

S&P 500 companies reported $192 billion in stock-based compensation expense in 2022 — roughly 1.2% of revenue — after growing more than 10% annually from 2010 through 2022. (Mercer Capital, Feb 2024)

📊 Non-GAAP vs GAAP Spread

31% Higher Non-GAAP

Across 70,000+ quarterly earnings announcements (2003–2021), non-GAAP earnings averaged 31% higher than GAAP earnings — largely because 60–70% of firms with significant SBC now exclude it from non-GAAP reporting. (Journal of Accounting and Economics, Oct 2025)

⚠️ SBC Dilution Range

0.2% – 8.6%/Year

A 2024 analysis of 104 public technology companies found annual SBC-driven dilution ranging from 0.2% to 8.6%, with many companies using share buybacks to offset the dilutive effect. (TDM Growth Partners, Jul 2025)

📋 10 Key Takeaways — What You Need to Know

Equity-based compensation touches the income statement, EPS, cash flow, and taxes — all differently. Here are the ten most important things to understand before reading a financial statement or making an investment decision.

#	What Happens	The Bottom Line
1	SBC reduces reported net income under GAAP	Under ASC 718 (US GAAP) and IFRS 2, the fair value of stock-based awards is recorded as a compensation expense over the vesting period. This directly reduces reported net income even though no cash leaves the company.
2	The expense is recognized at grant-date fair value — not current value	For equity-classified awards, fair value is locked in at the grant date using an option-pricing model (Black-Scholes or a lattice model). It does not change if the stock price rises or falls afterward. This is why SBC expense can look mismatched with market reality.
3	SBC lowers diluted EPS in two separate ways	First, it reduces the earnings numerator. Second, unvested options and RSUs are included in the denominator of diluted EPS via the treasury stock method, adding shares. Both effects compress the reported diluted EPS figure.
4	SBC is non-cash — it appears as an add-back in operating cash flow	Because no cash is paid at the time of grant or vesting (only at exercise for options), SBC is added back in the operating activities section of the cash flow statement. This is why a company can have strong reported cash flow but weak GAAP net income.
5	Most companies now exclude SBC from their non-GAAP “adjusted” earnings	Research published in the Journal of Accounting and Economics (2025) found 60–70% of firms with significant SBC now exclude it from non-GAAP reporting. Non-GAAP earnings averaged 31% higher than GAAP across 70,000+ announcements studied.
6	Investors still price in excluded SBC — the market is not fooled	The same 2025 academic study found that stock price reactions were similar regardless of whether SBC was excluded from non-GAAP. GAAP earnings (including SBC) actually explained investor reactions better than stripped non-GAAP earnings — evidence that markets are efficient at recognizing the real cost.
7	Technology companies carry far more SBC than the S&P 500 average	SBC as a percentage of revenue averages about 2% for S&P 500 companies overall. Emerging cloud companies averaged 21% (RBC Capital Markets data). Some SaaS companies see SBC consume more than 50% of revenue. For large-cap SaaS, SBC represents 39% of free cash flow vs 4% for the S&P 500.
8	US GAAP and IFRS treat the tax impact of SBC differently — affecting the income statement	IFRS routes tax windfalls and shortfalls from SBC directly to equity; US GAAP runs them through income tax expense on the income statement. This creates volatility in a US company’s effective tax rate that has nothing to do with operating performance.
9	High SBC is statistically associated with lower long-term returns	Morgan Stanley’s Counterpoint Global research found that the highest SBC issuers (as a share of sales) produced lower stock returns than the lowest issuers — and the effect was stronger among smaller companies. High SBC is not a free lunch for shareholders.
10	Regulatory scrutiny of non-GAAP exclusions is increasing	Non-GAAP measures have been the number one or two topic in SEC comment letters for nine consecutive years. The SEC requires GAAP metrics to be displayed with at least equal prominence to non-GAAP alternatives. In 2025, the FASB also proposed clarifications to diluted EPS calculations under ASC 260.

⚙️ How It Works: The Accounting Mechanics Explained

The Core Principle — ASC 718 (US GAAP) / IFRS 2

Grant-Date Fair Value Expensed Over the Vesting Period

When a company grants stock options or RSUs, the fair value of those awards is measured at the grant date — using option-pricing models for options, and stock price for RSUs. That value is then recognized as compensation expense, spread evenly over the vesting period (typically 3–4 years), reducing net income in each period. No cash changes hands. The offsetting entry goes to Additional Paid-In Capital (APIC), a component of shareholders’ equity.

📌 Income Statement

Reduces Net Income

SBC is embedded in operating expenses — allocated to COGS for direct labor, R&D for engineering staff, and SG&A for management and sales. The total appears in the footnotes, not always as a separate line.

📌 Balance Sheet

Increases APIC

The offsetting credit to the expense goes to Additional Paid-In Capital. No liability is created for equity-classified awards. When shares vest or options are exercised, shares are issued from treasury or newly authorized shares.

📌 Cash Flow Statement

Added Back in Operations

Because SBC involves no cash outflow at grant, it is added back as a non-cash item in operating activities — similar to depreciation. This inflates reported operating cash flow relative to GAAP earnings.

🔍 Where SBC Lives Inside Operating Expenses

Cost of Goods Sold (COGS): SBC awarded to employees who directly produce goods or provide services — manufacturing workers, customer support, software engineers building product features.
Research and Development (R&D): SBC for engineers, scientists, and product managers building future capabilities. Tech companies frequently carry the largest R&D SBC allocations.
Selling, General and Administrative (SG&A): SBC for executives, sales teams, finance, legal, and other overhead functions. CEO and C-suite awards often appear here.
Footnote disclosure: The total SBC expense for the period is disclosed in the equity compensation footnote, even when not broken out as a separate line on the face of the income statement. Investors must read footnotes to identify the full figure.

⚠️ US GAAP vs IFRS — The Key Difference That Affects the Income Statement

Both US GAAP and IFRS require expensing equity compensation at grant-date fair value over the service period. The most significant practical difference appears in tax accounting: under IFRS 2, gains (windfalls) and losses (shortfalls) that arise when the actual tax deduction at vesting differs from the expense recognized over the service period are recorded directly to equity. Under US GAAP, these differences flow through income tax expense on the income statement. This causes periodic swings in a US company’s reported effective tax rate — particularly in periods of large vesting events — that can confuse readers who do not understand the source.

📐 How SBC Affects Earnings Per Share — The Double Hit

💡

The Two-Front Attack on EPS

Stock-based compensation hits EPS from both directions simultaneously: it shrinks the numerator (by reducing net income) and expands the denominator (by adding potential shares). Understanding this double compression is essential to interpreting reported earnings.

EPS Component	How SBC Affects It	Accounting Standard
Numerator: Net Income	SBC expense reduces GAAP net income in each period. Even though no cash leaves, the income statement shows a lower profit figure — lowering the earnings available to common shareholders used in the EPS calculation.	ASC 718 / IFRS 2
Denominator: Basic EPS shares	Generally not affected during the vesting period — unvested awards are not outstanding shares and do not enter the basic EPS denominator. Exception: restricted stock units vested to retirement-eligible employees may move to basic EPS once the employee is retirement-eligible.	ASC 260
Denominator: Diluted EPS shares	Outstanding unvested options and RSUs are included in diluted EPS via the Treasury Stock Method (TSM). The method assumes hypothetical exercise proceeds are used to repurchase shares at the average market price; net incremental shares (outstanding minus hypothetical buyback) are added to the denominator.	ASC 260 / TSM
Performance-based awards (PSUs)	Treated as contingently issuable shares. Included in diluted EPS only if the performance condition would have been met if the reporting period end were the end of the performance period — a “bright line” test. Zero shares may be included until conditions are fully met.	ASC 260-10-45-48
Anti-dilutive awards	Awards where the hypothetical buyback shares exceed the weighted average shares outstanding — or out-of-the-money options — are excluded from diluted EPS (including them would increase EPS, violating the premise). These are disclosed in footnotes.	ASC 260-10-45-17
Companies reporting a net loss	When a company has a net loss from continuing operations, all potentially dilutive securities (including SBC awards) are excluded from diluted EPS because including them would be anti-dilutive in a loss scenario. FASB proposed Jan 2025 clarifications address edge cases here.	ASC 260 / FASB Jan 2025 proposal

🏦 The Treasury Stock Method — Plain Language Explanation

Under ASC 260, companies must calculate how many additional shares are effectively created by outstanding options and RSUs. The method works as follows: assume all in-the-money options are exercised and all RSUs vest today. Collect the hypothetical proceeds (exercise price paid by employees + remaining unrecognized compensation cost). Use those proceeds to buy back shares at the average stock price for the period. The difference between shares issued and shares repurchased is the net dilutive share count added to the denominator. If the stock price is high relative to the exercise price, fewer shares can be repurchased and dilution is greater. If the stock price is low, more can be bought back and dilution is smaller.

🔬 The Non-GAAP Debate — Is Excluding SBC Ever Justified?

Journal of Accounting and Economics — Griffin & McInnis (October 2025)

“Gone but Not Forgotten” — Investors Factor Excluded SBC Back In

This landmark peer-reviewed study analyzed 70,000+ quarterly earnings announcements from US public companies (2003–2021). Key finding: stock price reactions to earnings surprises were similar regardless of whether companies excluded SBC from non-GAAP reporting. GAAP earnings — which include SBC — explained investor reactions BETTER than non-GAAP earnings stripped of SBC costs. The authors conclude that SBC exclusions do not help investors value companies more accurately, and that the system is “working” — investors are not fooled.

✅ The Case FOR Excluding SBC

Non-Cash, Non-Recurring Framing

SBC requires no cash outflow at the time of grant. Supporters argue it distorts comparisons between companies with different compensation structures and that the Black-Scholes valuation may not reflect what the award is ultimately worth. Many Wall Street analysts build SBC exclusions into their standard models.

❌ The Case AGAINST Excluding SBC

Real Economic Cost to Shareholders

SBC is a recurring, predictable expense — not a one-time charge. When shares vest and exercise, existing shareholders face dilution: more shares divide the same earnings. Morgan Stanley Counterpoint Global found top SBC issuers consistently underperformed bottom issuers in long-run stock returns. It is a genuine employee cost, just paid in equity rather than cash.

🏛️ The SEC’s Position on Non-GAAP Metrics and SBC

Non-GAAP financial measures have been the number one or two topic in SEC comment letters for nine consecutive years (Financial Reporting Hub, confirmed 2025). Under Regulation G and Regulation S-K Item 10(e), the SEC requires that GAAP metrics be given at least equal prominence as any non-GAAP alternative. In a 2025 comment letter, the SEC required Sysco to display year-over-year GAAP net earnings changes before EBITDA. Companies that prominently advertise non-GAAP earnings figures while burying GAAP results face specific SEC comment letter challenges. The SEC does not prohibit SBC exclusion from non-GAAP metrics — but it requires clear disclosure and reconciliation.

Additionally, in January 2025, the FASB proposed amendments to ASC 260 to clarify diluted EPS calculations in specific scenarios involving loss from continuing operations and contracts that may be settled in stock or cash — with guidance effective for periods beginning after December 15, 2025.

📈 The Scale of SBC — Industry Benchmarks and Trends

🏢 S&P 500 Average

~2% of Revenue

For the broad S&P 500, SBC as a percentage of revenue averages approximately 2%. The total reached $192 billion in 2022 after growing at more than 10% annually from 2010 through 2022. SBC is growing faster than revenue even for mature companies. (Mercer Capital 2024, RBC Capital Markets)

☁️ SaaS and Cloud Tech

21%+ of Revenue

Emerging cloud (EMCLOUD) companies averaged 21% SBC as a percentage of revenue — a tenfold difference versus the S&P 500. Some SaaS companies see SBC exceed 50% of revenue. The 75th percentile of Nasdaq 100 SBC reached 6.8% of revenue in 2024 vs 4.5% in 2016. (RBC, NACD/Equity Methods 2025)

🧾 FCF Impact — Large-Cap SaaS

39% of Free Cash Flow

For large-cap SaaS companies, SBC represents approximately 39% of free cash flow — compared to just 4% for the broader S&P 500. This means “free cash flow” figures that add back SBC can dramatically overstate true cash generation available to common shareholders. (Wellington Management)

📉 Dilution Range

0.2% – 8.6%/Year

A 2024 analysis of 104 public tech companies found net annual SBC dilution ranging from 0.2% to 8.6%. Companies with the highest dilution ratios consistently underperformed peers in share price appreciation. Buybacks are increasingly common to offset dilution, though net dilution fell only modestly. (TDM Growth Partners, Jul 2025)

⚠️ The Free Cash Flow Illusion — What Investors Often Miss

Many company presentations, analyst reports, and media stories highlight “free cash flow” or “adjusted EBITDA” that adds SBC back as a non-cash item. This is technically correct — no cash left the building — but it can obscure a real economic cost. When SBC vests and employees sell shares, they are being paid by diluting existing shareholders. Morgan Stanley Counterpoint Global framed this clearly: when you add back SBC in non-GAAP results, you must explicitly recognize the employee’s claim on equity. Ignoring dilution while adding back SBC leads to systematic overvaluation in DCF and multiple-based models. The equivalence exists, but only when dilution is properly accounted for.

NACD/Equity Methods (May 2025): 6.8% Nasdaq 100 75th pctile 2024. TDM Growth Partners (Jul 2025): 0.2-8.6% dilution, buyback trends. Morgan Stanley Counterpoint Global: no free lunch; equivalence requires explicit dilution recognition; top SBC issuers underperform.

❓ Frequently Asked Questions

For equity-classified awards under US GAAP and IFRS — no. The compensation cost is fixed at the grant-date fair value. If you grant options when the stock is at $50 using a Black-Scholes value of $18 per option, you recognize $18 per option as compensation expense over the vesting period — regardless of whether the stock subsequently rises to $150 or falls to $10. This “set it and forget it” principle provides predictability in expense recognition. It also means that a company granting awards when its stock is at a peak will recognize high compensation expense even if employees eventually receive little value from underwater options.

Exception — liability-classified awards: Some awards are classified as liabilities rather than equity (for example, certain cash-settled awards). These must be remeasured at fair value at each reporting date, creating income statement volatility as the stock price changes.

Sources: ASC 718-10-30 (confirmed): equity-classified awards measured at grant date, no subsequent remeasurement. Bloomberg Tax ASC 740 guide (Jul 2025): distinction between equity-classified and liability-classified awards. CFA/Analyst Prep (Jan 2026): grant date fair value remains consistent under IFRS 2.

Under ASC 718, companies may account for forfeitures in one of two ways: (1) estimate the expected forfeiture rate upfront and reduce the expense recognized based on that estimate (adjusting as actual forfeitures occur), or (2) recognize forfeitures when they actually happen (reversing any previously recorded expense at that point). This is an entity-wide accounting policy election made by the company. When an employee forfeits an unvested award, the company reverses any compensation expense previously recognized for that employee’s specific award — effectively reducing total SBC expense. This is why reported SBC expense in a period of high employee turnover may be lower than expected — forfeitures reduce the total cost recognized.

Sources: ASC 718-10-35-1D and 718-10-35-3 (confirmed): forfeiture election; Deloitte DART ASC 260 7.1 (confirmed): forfeiture policy affects numerator in EPS; FASB ASU 2016-09: simplified accounting for forfeitures.

It depends on context and disclosure quality. There are legitimate reasons to present non-GAAP earnings alongside GAAP: SBC is non-cash, can distort period-to-period comparisons, and some analysts argue it represents a future dilution cost rather than a current period economic cost. The Wall Street convention of building SBC exclusions into analyst models is widespread and well-understood among professional investors.

However, a 2025 peer-reviewed study in the Journal of Accounting and Economics found that investors price in excluded SBC regardless — stock reactions were statistically similar whether or not the company excluded SBC. The conclusion: non-GAAP earnings excluding SBC do not give investors a better picture of value than GAAP earnings. The SEC views this as a concern: companies must present GAAP figures with at least equal prominence, provide full reconciliations, and cannot characterize SBC as non-recurring when it clearly recurs every year.

Sources: Journal of Accounting and Economics (Griffin, McInnis, Oct 2025): 60-70% exclude SBC; non-GAAP 31% higher; GAAP explains investor reaction better. Financial Reporting Hub (2025): SEC non-GAAP comment letters. SEC Regulation G, S-K Item 10(e): equal prominence requirement. CNBC (Sep 24, 2025): GAAP vs non-GAAP SBC analysis.

Under US GAAP, the tax effects of SBC can significantly distort the effective tax rate in ways unrelated to operating performance. Here is the core mechanism:

During the vesting period: Companies recognize a deferred tax asset equal to the tax benefit expected from the compensation deduction (GAAP expense × statutory tax rate). For example, $1M in SBC expense at a 21% tax rate creates a $210,000 deferred tax asset.
At vesting or exercise: The actual tax deduction is based on the intrinsic value at that time (stock price minus exercise price). If the stock price is higher than at grant, the tax deduction exceeds the GAAP expense — a “windfall” that flows through income tax expense, reducing the effective tax rate in that period. If the stock is lower — a “shortfall” — the effective tax rate rises.
Under IFRS: These windfalls and shortfalls go directly to equity, never touching the income statement. This is why comparable IFRS companies show more stable effective tax rates around SBC events than their US GAAP counterparts.

The practical implication: in a period of large RSU vestings at high stock prices (as seen in 2021), US tech companies reported very low effective tax rates — not because of aggressive tax planning, but because of SBC-related tax windfalls running through the P&L.

Sources: Bloomberg Tax / ASC 740 (Jul 2025): deferred tax asset, windfall/shortfall, Sec. 162(m) limitations; CFA/Analyst Prep (Jan 2026): GAAP vs IFRS tax treatment difference; ASC 718-10 (confirmed): APIC pool removed under ASU 2016-09.

Dilution is the reduction in existing shareholders’ ownership percentage and per-share earnings when new shares are issued. Here is the direct mechanism with equity compensation:

When an employee exercises stock options, the company issues new shares. If it had 100 million shares outstanding and issues 2 million from option exercises, the existing shareholders now own 100/102 = 98% of what they owned before. The same total earnings are divided among 2% more shares.
When RSUs vest, shares are delivered to employees — again increasing the share count unless offset by buybacks.
The net effect on diluted EPS: even before exercise occurs, potential shares from options and RSUs are included in the diluted EPS denominator via the treasury stock method — so reported diluted EPS already reflects the potential dilution.
Share buybacks are commonly used to offset dilution: a company repurchases shares on the open market equal to the number expected to be issued via SBC. This maintains the share count but uses cash — converting what was presented as a non-cash expense into a real cash cost at the company level.

Morgan Stanley’s Counterpoint Global analysis showed that when SBC is correctly accounted for — including the dilution it creates — there is no free lunch. The equity value per share is the same whether you recognize the expense or explicitly recognize the dilution; you just get different multiples and different visual presentation of the economics.

Sources: Morgan Stanley Counterpoint Global: dilution equivalence, no free lunch, top issuers underperform. Analyst Prep (Jan 2026): dilution, ownership percentage. CNBC (Sep 24, 2025): dilution increases shares in denominator. TDM Growth Partners (Jul 2025): buyback trends; net dilution 0.2-8.6%.

📊 Options vs RSUs — Side-by-Side Comparison

Feature	Stock Options	Restricted Stock Units (RSUs)
Valuation Method	Black-Scholes or lattice model at grant date — incorporates volatility, time to expiration, risk-free rate, dividend yield	Current stock price at grant date (fair market value) — simpler to calculate
Expense Recognition	Spread over vesting period (typically 3–4 years, often with a one-year cliff). Higher expense when stock is volatile at grant.	Spread over vesting period at the grant-date stock price. Expense directly tied to share price at grant — no option pricing model needed.
EPS Dilution (TSM)	Exercise price proceeds + unrecognized compensation cost used to hypothetically buy back shares. Out-of-the-money options excluded (anti-dilutive).	No exercise price proceeds (most RSUs have $0 exercise price). Only unrecognized compensation cost used for hypothetical buyback — generally produces more dilution per unit than options.
Tax Deduction	For NQSOs: deduction at exercise equal to intrinsic value. For ISOs: no deduction unless disqualifying disposition. Creates GAAP/tax basis difference.	Deduction at vesting equal to fair market value at vesting date. Company recognizes deferred tax asset over vesting period; true-up at vest.
Shareholder Perspective	Only worth something if the stock price exceeds the exercise price. Higher leverage but more risk of becoming worthless (underwater).	Always have value as long as the stock is worth anything. Greater certainty of cost to the company and value to employee. Now far more common than options for most companies.

Performance Share Units (PSUs) and performance stock options introduce additional complexity into both expense recognition and EPS:

Expense recognition: For awards with service and performance conditions (but not market conditions), the amount of compensation expense recognized depends on the estimated number of awards expected to vest — which tracks the likelihood of hitting performance targets. If a company initially assumes 80% of PSUs will be earned and later revises the estimate upward to 100%, a catch-up adjustment increases SBC expense in that period — creating a lumpy earnings impact.
Awards with market conditions (e.g., total shareholder return vs. peers): measured using a Monte Carlo simulation. Crucially, the expense is NOT reversed if the market condition is not met — this contrasts with performance conditions. The probability is baked into the grant-date fair value permanently.
EPS impact: PSUs are contingently issuable shares. They enter the diluted EPS denominator only if the performance condition would be satisfied if the reporting date were the end of the performance period — the “bright line” test under ASC 260-10-45-48. This means a PSU with a high performance target may contribute zero dilutive shares for several periods, then spike suddenly when the target is crossed.

Sources: ASC 260-10-45-48 through 45-57 (confirmed): contingently issuable shares, bright line test; Equity Methods EPS Hot Topics (Dec 2020, confirmed): performance/market conditions, spike from zero to full dilution; CFA/Analyst Prep (Jan 2026): Monte Carlo for market conditions, no reversal.

Yes — and this is one of the most important issues for investors analyzing tech companies. Here is the full mechanism:

On the cash flow statement, SBC is listed as a non-cash add-back in operating activities (similar to depreciation). This is technically accurate — the company did not write a check. As a result, operating cash flow and free cash flow are higher than GAAP net income by the full SBC expense amount. A company with $1 billion in GAAP losses can simultaneously report $2 billion in “operating cash flow” if it has heavy SBC.

Wellington Management data shows that for large-cap SaaS companies, SBC represents 39% of reported free cash flow. This means that when an analyst says a SaaS company has a “20% free cash flow margin,” the true margin — if employees were paid in cash rather than stock — could be dramatically lower. The real-world cost is paid by existing shareholders through dilution when those shares vest and are sold. Many investor relations presentations emphasize FCF while downplaying the dilutive cost, creating a presentation asymmetry that the SEC has increasingly flagged.

Sources: Wall Street Prep (confirmed): SBC add-back in operating activities. Wellington Management (via multiple sources): 39% FCF SaaS vs 4% S&P 500. Morgan Stanley Counterpoint Global: add-back SBC requires explicit dilution recognition. Financial Reporting Hub (2025): SEC flagging FCF and non-GAAP presentation issues.

Valuation professionals and researchers suggest a clear framework:

Treat SBC as a real economic cost. Whether you use GAAP earnings (which include SBC expense) or non-GAAP earnings + dilution adjustment, the economics must be recognized somewhere. Ignoring both leads to overvaluation.
If using GAAP earnings: Include the SBC expense in your earnings base. The resulting P/E multiple will appear higher for companies with heavy SBC — but that is appropriate if their growth prospects justify it.
If using non-GAAP earnings (excluding SBC): You must explicitly model the dilutive effect of SBC awards on future share counts. Do not use the same share count and valuation multiple you would use for a company paying cash compensation. The Morgan Stanley framework shows this produces the same value — but different multiples.
Compare SBC as % of revenue across competitors. A company using 20% SBC/revenue to generate 15% revenue growth may be less economically efficient than a competitor using 5% SBC/revenue to generate 12% revenue growth.
Watch buyback quality. Many companies buy back shares to offset SBC dilution. This converts a non-cash expense to a real cash expense. True “shareholder-friendly” buybacks reduce the share count; buybacks that merely offset SBC issuance are expense-covering.
Read the footnotes. The total SBC expense is in the equity compensation footnote. Future dilution from outstanding awards is in the stock-based compensation rollforward table.

Journal of Accounting and Economics (Oct 2025): GAAP earnings explain investor reaction better than non-GAAP.

Several important developments are active or recent:

FASB ASC 260 proposed amendments (January 2025): The FASB proposed clarifications to how diluted EPS is calculated when a company has a loss from continuing operations and has contracts that can be settled in stock or cash (reported as an asset or liability). The proposed amendments would require evaluating whether including potential common shares is dilutive by looking at the combined numerator and denominator effect — even in loss scenarios. Effective for annual periods beginning after December 15, 2025; early adoption permitted.
New ASC 718 guidance effective December 15, 2025: Additional share-based payment guidance for periods and interim periods beginning after this date, with early adoption permitted for financial statements not yet issued. Practitioners are advised to seek external expertise for complex scenarios.
SEC comment letter focus: For the year ended June 30, 2025, non-GAAP measures remained a top SEC comment letter topic. The SEC is specifically scrutinizing: (1) GAAP not given equal prominence, (2) non-GAAP metrics that exclude recurring expenses like SBC without adequate explanation, and (3) FCF measures that appear misleadingly high due to SBC add-backs.
ISS equity plan scorecards (2025): No changes were announced to ISS scorecards from the 2024 framework, maintaining continued focus on plan cost, plan features, and historical grant practices. 92% of S&P 500 equity plans received institutional investor approval in H1 2024 — but scrutiny of dilution and share recycling provisions remains high.
AI-linked performance metrics: In 2025-2026, boards are increasingly considering AI-related performance metrics in PSU designs — introducing new valuation and EPS complexity as these contingent structures must be modeled under ASC 260.

📖 Essential Terms — Plain-Language Glossary

ASC 718

The US GAAP standard for SBC

FASB Accounting Standards Codification Topic 718 — the primary rule governing how US companies recognize, measure, and disclose share-based compensation expense. Requires grant-date fair value expensed over the vesting period.

Treasury Stock Method (TSM)

How diluted EPS adds shares

Under ASC 260, the method for calculating how many net incremental shares are added to the EPS denominator from in-the-money options and RSUs. Assumes hypothetical exercise proceeds are used to repurchase shares at the average market price.

Diluted EPS

EPS including all potential shares

Earnings per share calculated using the weighted average shares outstanding plus all potentially dilutive securities (options, RSUs, PSUs, convertibles). Always lower than or equal to basic EPS. The more conservative and complete measure.

Non-GAAP Earnings

Adjusted earnings excluding SBC

Company-defined earnings metrics that exclude certain GAAP items — most commonly SBC, amortization, and restructuring. Must be reconciled to GAAP and cannot be given greater prominence than GAAP measures per SEC rules.

APIC (Additional Paid-In Capital)

Where the SBC credit goes

The balance sheet equity account that receives the offsetting credit when SBC expense is recognized. APIC increases as stock-based awards are expensed over time. When awards are exercised or shares issued, APIC and common stock are adjusted accordingly.

Grant-Date Fair Value

The locked-in expense basis

The value of an equity award measured at the date it is granted, using option-pricing models (for options) or current stock price (for RSUs). Under equity-classified accounting, this figure does not change regardless of subsequent stock price movements.

✅ The Five Things That Matter Most for Investors and Analysts

SBC is a real economic cost — it reduces GAAP earnings through the income statement and dilutes shareholders through share issuance. Neither effect can be safely ignored in any rigorous analysis.
Non-GAAP earnings excluding SBC average 31% higher than GAAP. Research published in 2025 (Journal of Accounting and Economics) confirms investors price in excluded SBC regardless — GAAP earnings explain stock reactions better than non-GAAP for SBC-heavy companies.
Tech and SaaS companies carry disproportionate SBC. Emerging cloud companies average 21% SBC/revenue vs 2% for the S&P 500. For large-cap SaaS, SBC consumes 39% of reported free cash flow — making FCF-based valuations potentially misleading without adjustment.
EPS is hit twice: Net income shrinks (numerator) and potential shares expand (denominator via the Treasury Stock Method). Understanding both effects is required to interpret reported diluted EPS accurately.
Regulatory scrutiny is intensifying. Non-GAAP metrics have been a top SEC comment letter topic for nine consecutive years. The FASB proposed ASC 260 clarifications in January 2025. Companies excluding SBC must show full reconciliations and cannot present non-GAAP with greater prominence than GAAP.
