Glaeser and Lang (2024; GL) reviews the accounting literature on innovation, which has increased substantially in recent years. GL makes an important contribution to accounting research by bringing into the literature the implications of Romer's Nobel Prize winning endogenous growth theory and by explaining how accounting research addresses questions related to innovation. We contribute to accounting research by building on GL's foundation to suggest three main paths forward for future innovation research. First, focus on innovation's three defining attributes: novelty, nonrivalry, and partial excludability. Second, determine the needs of various users of information about a firm's innovation activities and how to meet those needs; we focus on the needs of investors. Third, address questions our discussion highlights as potentially important for future research on financial reporting and innovation, including the crucial question of an innovation's identifiability.

Most research on non-GAAP financial measures focuses on earnings or earnings per share, although non-GAAP revenue disclosure has recently attracted SEC scrutiny. It is unclear ex ante what non-GAAP adjustments could improve revenue's usefulness because, unlike earnings, revenue is a top-line number related primarily to core (i.e., persistent) business activities. We present the first archival analysis of non-GAAP revenues using a large, hand-collected sample of disclosures from 2015 to 2018. Approximately one in five earnings announcements contains a non-GAAP revenue disclosure, focused on revenue growth. Our evidence suggests that firms disclose non-GAAP revenue when GAAP revenue is incomparable with prior periods, and not to compensate for poor GAAP performance. Furthermore, non-GAAP revenue growth predicts future revenue growth better than GAAP revenue growth, and the market responds to this information. Overall, non-GAAP revenue disclosures are motivated by economic fundamentals rather than opportunism, on average, and they provide investors with relevant information.

Each year, the NCAA basketball tournament (March Madness) is a daytime distraction for millions of people, providing a largely exogenous shock to investor attention. We investigate whether March Madness influences the market response to earnings by diverting investor attention away from earnings news. We find that the price reaction to earnings news released during March Madness is muted. This result generally holds across several samples and additional analyses. We also find that the result is more muted for low institutional ownership firms, consistent with the effect being driven by less‐sophisticated investors. Furthermore, we find that it takes the market 30 to 60 days to correct for the distraction effect. Overall, we provide a unique test of the theory of limited attention by documenting that extraneous events can have a significant impact on the pricing of earnings.

The SEC prohibits the presentation of non‐GAAP measures before corresponding GAAP measures; however, a large proportion of non‐GAAP reporters present non‐GAAP EPS before GAAP EPS in their earnings announcements. This noncompliance raises questions about whether firms use prominence to highlight higher or lower quality non‐GAAP information. For firms reporting non‐GAAP EPS between 2003 and 2016, prominent non‐GAAP EPS is associated with higher quality non‐GAAP reporting. Further tests reveal that nonregulatory incentives, rather than regulatory costs, explain this relation. Specifically, prominence is associated with higher quality non‐GAAP reporting in settings where prominence is not regulated, investors ignore prominence when non‐GAAP reporting quality is lower, and the minority of firms using prominence to mislead exhibit characteristics associated with weaker investor monitoring. Overall, we provide evidence that regulatory noncompliance can reflect an intent to inform, and that most firms use prominence to highlight higher quality non‐GAAP information despite prohibitive regulation.

We use newly available GAAP forecasts to document that traditionally-identified GAAP forecast errors contain 37% measurement error. Correcting for this measurement error, we settle a long-standing debate regarding investor preference for GAAP versus non-GAAP earnings and provide strong evidence of a preference for non-GAAP earnings. We also revisit the use of non-GAAP exclusions to meet analysts’ forecasts when GAAP earnings fall short. Results indicate that 34% of these traditionally-identified meet-or-beat firms are misidentified due to measurement error, and this error masks evidence that firms more frequently exclude transitory rather than recurring expenses for meet-or-beat purposes.

Researchers frequently proxy for managers’ non‐GAAP disclosures using performance metrics available through analyst forecast data providers (FDPs), such as I/B/E/S. The extent to which FDP‐provided earnings are a valid proxy for managers’ non‐GAAP reporting, however, has been debated extensively. We explore this important question by creating the first large‐sample data set of managers’ non‐GAAP earnings disclosures, which we directly compare to I/B/E/S data. Although we find a substantial overlap between the two data sets, we also find that they differ in systematic ways because I/B/E/S (1) excludes managers’ lower quality non‐GAAP numbers and (2) sometimes provides higher quality non‐GAAP measures that managers do not explicitly disclose. Our results indicate that using I/B/E/S to identify managers’ non‐GAAP disclosures significantly underestimates the aggressiveness of their reporting choices. We encourage researchers interested in managers’ non‐GAAP reporting to use our newly available data set of manager‐disclosed non‐GAAP metrics because it more accurately captures managers’ reporting choices.

We provide the first evidence after Regulation G on firms’ non-GAAP EPS denominator choices and whether they are informative or opportunistic. From 2013 to 2019, 17 percent of annual non-GAAP EPS numbers use denominators different from that of GAAP diluted EPS, which makes denominator adjustments among the most prevalent individual types of non-GAAP adjustments. For firms reporting GAAP and non-GAAP profits or GAAP losses and non-GAAP profits, we provide evidence consistent with denominator adjustments increasing non-GAAP EPS informativeness. Our evidence also suggests that opportunism in denominator choices is concentrated in firms reporting GAAP losses and non-GAAP profits and failing to adjust the denominator. Such nonadjustment is inconsistent with SEC requirements to report non-GAAP EPS “on a diluted basis” because the EPS denominator for a GAAP loss excludes dilutive claims. Although the SEC largely overlooks such firms, they are more likely, on average, to report non-GAAP EPS that analysts consider inflated.

We investigate whether firms manage stock prices in anticipation of share issuance. Warrant exercise results in share issuance and warrant expiration dates are fixed years in advance, which precludes market timing. We predict firms manage stock prices to prevent (induce) warrant exercise when exercise is dilutive (anti-dilutive) to existing shareholders. To test our prediction, we examine stock returns around warrant expiration dates. We find that the difference between out-of-the-money (OTM) and in-the-money (ITM) firms' return patterns (i.e., post-expiration minus pre-expiration returns) is positive, and OTM (ITM) firms' return pattern is positive (negative). Return patterns of three sets of pseudo warrant firms differ from patterns of warrant firms. Return patterns are stronger when more feasible price changes are required to affect warrant expiration status, and firm-issued news items is a mechanism for price management. Thus, our findings provide evidence that firms engage in stock price management in anticipation of share issuance.
