GAAP Earnings exaggerated the drop in 2020 and overstated the rebound in S&P 500 earnings in 2021. I see the same trends in Street Earnings, as reflected in Zacks Earnings, which are reported to be adjusted to remove non-recurring items using standardized assumptions from the sell-side. This report shows:
- the prevalence and magnitude of overstated Street Earnings in the S&P 500
- why Street Earnings (and GAAP earnings) are flawed
- five S&P 500 companies with overstated Street Earnings and a Very Unattractive Stock Rating
Over 160 S&P 500 Companies Overstate EPS by More than 10%
For 336 companies in the S&P 500, Street Earnings overstated Core Earnings for the trailing-twelve-months (TTM) ended calendar 2021. In the TTMs ended 3Q21 and 4Q20, even more, 360 companies and 351 companies overstated their earnings. When Street Earnings overstate Core Earnings, they do so by an average of 21% per company, per Figure 1. For over a third of S&P 500 companies, Street Earnings overstate Core Earnings by >10%.
Figure 1: Street Earnings Overstated by 21% on Average in 2021
The 336 companies with overstated Street Earnings make up 79% of the market cap of the S&P 500, which is the fifth-highest percent since 2012 (earliest data available), measured with TTM data in each quarter. Figure 2 shows that roughly 80%, by market cap, of the S&P 500 has overstated earnings for most of the last two years.

Figure 3 shows five S&P 500 stocks with a Very Unattractive Stock Rating and the most overstated Street Earnings (Street Distortion as a % of Street Earnings per share) over the TTM through 4Q21. “Street Distortion” equals the difference between Core Earnings per share and Street Earnings per share. Investors using Street Earnings miss the true profitability, or lack thereof, of these businesses.

In the section below, I detail the hidden and reported unusual items that distort GAAP Earnings for Illumina Inc. ILMN , one of the stocks in April’s Most Dangerous Stocks Model Portfolio. All these unusual items are removed from Core Earnings.
Illumina’s (ILMN) 2021 Street Earnings Overstated by $6.20/share
The difference between Illumina’s Street Earnings ($5.96/share) and Core Earnings (-$0.24/share) is 6.20/share, per Figure 4. That difference is the Street Distortion, which for Illumina is 104% percent of Street Earnings.
Illumina’s GAAP Earnings overstate Core Earnings by $5.29/share. Street Earnings are more distorted by unusual items than GAAP earnings for Illumina.

Below, I detail the differences between Core Earnings and GAAP Earnings so readers can audit my research. I would be happy to reconcile Core Earnings with Street Earnings but cannot because I do not have the details on how analysts calculate their Street Earnings.
Illumina’s Earnings Distortion Score is strong miss and its Stock Rating is very unattractive. As noted above, Illumina is in April’s Most Dangerous Stocks Model Portfolio due to its overstated earnings and expensive valuation. Despite trading at $364/share, ILMN has an economic book value (EBV), or no growth value, of -$2/share.
Figure 5 details the differences between Illumina’s Core Earnings and GAAP Earnings.

Total Earnings Distortion of $5.28/share, which equals $798 million, is comprised of the following:
Reported Unusual Gains Pre-Tax, Net = $7.07/per share, which equals $1.1 billion. Each of the below items was bundled in Other Income on Illumina’s income statement. I relied on the breakout of Other Income on page 78 of its 2021 10-K to learn that it contained:
Hidden Unusual Expenses, Net = -$0.93/per share, which equals -$141 million and is comprised of
- -$156 million in transaction costs related to the acquisition of GRAIL bundled in SG&A – Page 68
- -$1 million expense due to the change in estimated fair value of contingent consideration bundled in SG&A – Page 65
- $16 million in sublease income – Page 73
Tax Distortion = -$0.85/per share, which equals -$129 million
Given the similarities between Street Earnings for Illumina and GAAP Earnings, my research shows both Street and GAAP earnings fail to capture significant unusual items both hidden and reported directly on Illumina’s income statement.
