Signaling corporate strategy in IPO communication: a study of biotechnology IPOs on the NASDAQ.


by Gao, Hongzhi^Darroch, Jenny^Mather, Damien^MacGregor, Alan

A clear corporate strategy communication can be a signal to financial analysts and public investors at the time of an initial public offering (IPO). This study examines IPO prospectuses of 57 biotechnology firms listed on the NASDAQ between 1997 and 2002. Using regression analysis, this article shows that the clarity, intensity, and consistency of the corporate strategy signal are not strong enough to affect the 1st-day initial returns. However, consistent communication of a prospector strategy negatively impacts 30-day initial returns, whereas consistent communication of a defender strategy positively impacts 30-day initial returns.

**********

Uncertainty characterizes the time surrounding an initial public offering (IPO). It is difficult to predict how the market will perform following the IPO date (Ibbotson, 1975). Similarly, determining a fair market value of the firm is complex because of the newness of the firm to the market (Certo, 2003) and the entrepreneurial nature of some IPO firms (Certo, Daily, & Dalton, 2001; Daily, Certo, Dalton, & Roengpitya, 2003). Researchers attribute this uncertainty to information asymmetry or knowledge gaps between informed and uninformed investors (Ibbotson, 1975; Ibbotson, Sindelar, & Ritter, 1988; Rock, 1986). Although some debate exists about which investors are more informed, this article takes the positions that (a) IPO issuers are more informed than public investors and (b) institutional investors are more informed than small investors (Daily et al., 2003; Ritter & Welch, 2002).

Extant research has applied signaling theory widely to address this information asymmetry dilemma (Daily et al., 2003). Signaling theory suggests that certain indicators provide signals to potential investors about the capabilities of the IPO firm and therefore the likely future value of the firm (Deeds, DeCarolis, & Coombs, 1997). Research reports that credible communication outlining important information at the time of an IPO can reduce the information asymmetry between IPO issuers and investors. So far, the types of information included in research are (a) the composition of the board; (b) the reputation of the underwriter; (c) the source and amount of venture capital; (d) the nature of the firm's intellectual capital; and (e) the ability of those within the firm to manage knowledge. Credible communication also helps IPO issuers reduce the information asymmetry between informed and uninformed investors and maximize the value of going public (Azarmi, 2002; Bukh, Nielsen, Gormsen, & Mouritsen, 2002; Carter, Dark, & Singh, 1998; Certo et al., 2001; Megginson & Weiss, 1991; Neck, Welbourne, & Meyer, 2000; Rosenstein & Wyatt, 1997). One possible explanation for the link between credible communication and the value of an IPO is that shareholders increasingly seek strategic information (such as the information described above) in order to explain an investment opportunity (Brown, 1997; Desai, 2000; Higgins & Diffenbach, 1989; Neck et al., 2000).

A group of studies reports that communication on corporate strategy received by the stock market has a significant impact on the value of shares in the market (Day & Fahey, 1990; Higgins & Bannister, 1992; Higgins & Diffenbach, 1985; Parnell & Wright, 1993). However, we are not aware of any published studies that empirically examine the relationship between corporate strategy communication and returns to IPO investors on both the 1st day and in the short-term after-IPO market (e.g., 30-day returns). This oversight is surprising because the communication of corporate strategy has been extensively argued to affect the market price and shareholder value in the long after-IPO market (e.g., a year or more after the event; Day & Fahey, 1990; Desai, 2000; Higgins & Bannister, 1992; Higgins & Diffenbach, 1985). This article proposes that the communication of corporate strategy at the time of an IPO provides cues to assist analysts and investors in deciding whether or not to invest in an IPO firm. This view becomes particularly important when the IPO firm first goes public because IPO managers must find a mechanism to communicate their firm's quality in order to reduce the ex ante uncertainty and thus reduce the need to discount the stock price to attract less-informed investors (Daily et al., 2003). Through the credible communication of corporate strategy, investors and analysts will better understand a firm's strategic posture, activities, and plans and then be able to assess the fit between internal resources, the firm's corporate strategy, and the external environment in which the firm operates. Thus, by obtaining strategic information, investors and analysts are in a better position to infer the potential value of the firm (Day & Fahey, 1990). This article proposes a significant advantage for an IPO firm that provides as part of IPO documentation an overview of the firm's corporate strategy as "information cue" (Miles & Snow, 1978).

Underpricing is generally defined as the difference between the price at which the firm's stock was initially offered and the stock's closing price on the 1st day of trading (Ibbotson, 1975; Ibbotson et al., 1988; Ritter, 1998). Although a number of theoretical explanations (e.g., risk-averse underwriter, information asymmetry, and bandwagon) exist for IPO underpricing, this article adopts the information asymmetry approach. Therefore, we assert that if IPO communication is credible, then underpricing will be minimized and so the 1st-day returns will be close to expected returns (Certo et al., 2001; Ritter, 1998).

Of the studies that examine the relationship between an IPO event and investor returns, most focus on the returns on the 1st day of an IPO event as an indicator of information asymmetry in the market (Bukh et al., 2002; Certo, 2003; Certo et al., 2001; Durukan, 2002; Megginson & Weiss, 1991; Neck et al., 2000; Rosenstein & Wyatt, 1997). However, we also propose that returns at some stage after an IPO event should be examined because of market instability and opportunistic behavior surrounding the IPO event. By taking a slightly longer term view (in this case, 30 days after an IPO event), this research controls for the effect of opportunistic investors who order stocks before the 1st day and then on-sell these stocks soon after (Finkle & Lamb, 2002; Ritter, 1991, 1998). Accordingly, this research includes both investor returns on the 1st day and 30 days after an IPO event to examine the effect of the strategy signal.

This article is structured as follows: We begin by presenting a theoretical framework, based on market signal and corporate strategy theory, before presenting research hypotheses. Next, the population of biotechnology IPO firms used in the nominated time period is described and an overview of the content analysis method used for data analysis is provided. Finally, we discuss our findings and the implications of these for both research and practice.

LITERATURE REVIEW

Corporate Strategy and Shareholder Value

Corporate strategy can influence the performance of an organization (Mintzberg, Lampel, Quinn, & Ghoshal, 2003). With a sound corporate strategy, a firm can consistently create high value through its integrated business activities; with a weak corporate strategy, the value of a firm's business activities deteriorates (Goold, Campbell, & Alexander, 1994). Thus, shareholders see corporate strategy as an important proxy for the likely value of the firm (Day & Fahey, 1990).

Corporate strategy provides a navigation map to the investors and analysts (Desai, 2000). The effective communication of corporate strategy is important because it builds relationships with and encourages the involvement of investors and analysts (Bukh et al., 2002; Desai, 2000). Effective communication of corporate strategy can also enhance shareholder satisfaction (Higgins & Bannister, 1992) and build employee morale (Burgi & Roos, 2003). Credible communication further enables managers within the firm to crystallize and clearly articulate corporate strategy to employees and investors alike. This, in turn, helps managers reinforce or redevelop strategic choices (Burgi & Roos, 2003) and increases the confidence stakeholders place upon the strategic ability of management (Mintzberg et al., 2003).

Although those within the firm endeavor to better communicate corporate strategy, evidence suggests that shareholders also seek to better understand the strategic posture of the firm (Day & Fahey, 1990; Rapport, 1981). Possible explanations for this phenomenon are as follows: (a) The environment in which many firms operate is ever more dynamic and competitive (Brown, 1997; Lynch, 2000; Mintzberg et al., 2003; Rapport, 1981); or (b) traditional financial measures are no longer comprehensive indicators of internal management capabilities (Beattie, 1999; Eccles, Hertz, Keegan, & Philips, 2001). This second point is especially relevant with IPO firms, which often lack financial history; furthermore, any history might be distorted by a long R&D stage and negative profit (Cumby & Conrod, 2001).

Corporate Strategy as an IPO Market Signal

Spence (1973, 1974) introduces the concept of a market signal when studying the labor market to explain an observable proxy that can be used to predict unobservable attributes of the issue under examination (Spence, 1973). As an example, Spence (1973) argues that employers could use the education level of a job applicant as a signal of the likely productive capability of that applicant (Spence, 1973). Thus, market signals reduce the amount of information asymmetry between buyers and sellers and, accordingly, improve the effectiveness and efficiency of a market (Engers, 1987). For a market signal to work, the key requirements are that information (a) is observable, (b) is difficult to alter, (c) is costly to produce and change, (d) is difficult to imitate, (e) reduces asymmetry between signal senders and receivers, and (f) is persistent (Riley, 1975; Spence, 1973, 1974).

This study classifies IPO prospectuses as a market signaling activity because the IPO prospectus attempts to reduce information asymmetry between those buying and selling stocks in the IPO firm. Based on market signaling literature, the following observations are made to support the positioning of corporate strategy communicated from IPO prospectuses as a market signal. First, the corporate strategy of an IPO company is an observable and easy-to-notice piece of information from an IPO prospectus (Marino, Castaldi, & Dollinger, 1989). The IPO prospectus provides greater detail about a company's strategic planning, products/markets, and management structure than any other form of communication (e.g., press releases, road shows, advertisements) and so has the potential to capture investors' attention at the time of the IPO event. Prospectuses are widely used by investors and their reference groups (e.g., analysts) to understand the likely value of the firm (Cumby & Conrod, 2001; Marino et al., 1989; Song, Rhee, & Adams, 2001).

Second, prior to publication, the strategic information communicated in an IPO prospectus can be altered by managers (Meek, Roberts, & Gray, 1995). Once published, however, managers need to implement those strategies in order to win the ongoing trust from investors and analysts. Third, the establishment and communication of a firm's corporate strategy are costly, risky (Porter, 1980), and difficult to imitate. Due to the nature of the corporate strategy in addressing multiple dimensions of a business, its formulation and implementation are a gradual and costly process (Doty, Glick, & Huber, 1993; Miles & Snow, 1978; Parnell & Wright, 1993). A strategy will be seen as credible when there is a perceived fit between the strategy itself and the context within which the firm operates, for example, the product/market environment, technology environment, and management structure (Doty et al., 1993; Miles & Snow, 1978). The requirement for fit makes imitation by competitors difficult. A "hurried" announcement of a corporate strategy may lead to a negative reaction from the market because investors and their reference groups will evaluate the firm's performance based on the announced strategic plan (Day & Fahey, 1990; Higgins & Bannister, 1992; Higgins & Diffenbach, 1985, 1989).

Fourth, strategic information asymmetry exists between the management team in an IPO firm and outside investors in the IPO market (Beatty & Ritter, 1986; Rock, 1986). This information asymmetry can be reduced when investors accept corporate strategy as a cue. Through the clear identification of corporate strategy, investors and analysts can better understand a firm's strategic posture, activities, and plans and assess the fit between internal resources and the external environment in which the firm operates. Investors and analysts are therefore in a better position to infer the potential value of the firm, taking into account other financial performance data (Day & Fahey, 1990). In addition, the information disclosure of a public firm following an IPO is persistent (Baruch, 1992) and either reinforces or diminishes the signal. This article proposes a significant advantage for an IPO issuer that provides an overview of the firm's corporate strategy as information cue (Miles & Snow, 1978) as part of the IPO documentation.

Miles and Snow Strategy Typology

Having established the importance of corporate strategy as a market signal, this article now considers types of strategy. In this study, the Miles and Snow strategy typology is used to classify the corporate strategy communicated during an IPO event. Compared with other typologies (Ansoff, 1965; Mintzberg, 1987; Porter, 1980), the Miles and Snow typology focuses more on the strategic intentions of the firm rather than actual strategic performance. This typology is particularly useful at predicting the likely future strategic behaviors and performance of the firm (Doty et al., 1993; Segev, 1989; Shortell & Zajac, 1990) and so is appropriate for IPO firms. The Miles and Snow strategy typology also enables an integrated and systematic examination of the strategic patterns of the firm (McDaniel & Kolari, 1987; Zahra, 1987).

The Miles and Snow (1978) typology addresses three problems a firm might confront: entrepreneurial (product/market) problems, technological (engineering) problems, and administrative problems. The classification of firms into one of four strategy types--prospectors, defenders, analyzers, and reactors--depends on how a firm addresses these three basic problems.

Prospectors perceive a dynamic, uncertain environment and maintain flexibility in order to compete in the market (Parnell & Wright, 1993). As such, prospectors usually target broad markets and continually search for new market opportunities. Prospectors are creators of change and uncertainty, to which their competitors must respond (Shoham, Evangelista, & Albaum, 2002). To maintain the advantage of innovation, prospectors tend to possess a loose structure, low division of labor, and low formalization and centralization (Parnell & Wright, 1993).

Defenders perceive a stable and certain environment and thus seek stability and control in their operations in order to achieve maximum efficiency (Parnell & Wright, 1993). Defenders have narrow product/market domains (Miles & Snow, 1978) and defend them aggressively (Shoham et al., 2002). New product development primarily relates to existing products and markets (Miles & Snow, 1978). Because of this narrow focus, defenders improve the efficiency of their existing operations with a cost-efficient, single-core technology (Shoham et al., 2002). Defenders adopt an extensive division of labor, high formalization, and high centralization (Parnell & Wright, 1993).

Analyzers simultaneously highlight stability and flexibility and attempt to take advantage of both the prospector and defender strategy types (Parnell & Wright, 1993). Analyzers operate in two types of product/market domains, one relatively stable and the other changing (Miles & Snow, 1978). They seek efficiency in stable areas with formalized structures and processes. At the same time, analyzers monitor their competitors closely for new ideas in more turbulent areas, preferring to imitate them rapidly. Analyzers characteristically exert tight control over existing operations and loose control over new undertakings. As Parnell and Wright (1993) note, "The strength of the Analyzer is the ability to respond (imitate) to Prospectors while maintaining efficiency in operations" (p. 30).

In stark contrast to the other three strategy types is a reactor, which lacks a consistent strategy-structure relationship and seldom makes adjustments unless forced to do so due to environmental pressures (Miles & Snow, 1978). Some researchers describe a reactor strategy as a residual or unsuccessful strategy type (Hambrick, 1983; Zajac & Shortell, 1989). This study excludes this strategy type because it is unlikely that an IPO firm will deliberately pursue or signal an unsuccessful strategy type.

The Miles and Snow strategy typology provides a functional device that enables firms to be differentiated from one another according to their product/ market choices, distinctive adaptive processes, and internal structures. This, in turn, allows the firms to align to the environment in which they operate (Hambrick, 1983; McDaniel & Kolari, 1987; Snow & Hrebiniak, 1980; Woodside, Sullivan, & Trappey, 1999). Table 1 summarizes the characteristics of each strategy type and subdomains used in this study. This study presents an IPO prospectus as a market signaling device that provides accurate insights into the firm's potential (Daily et al., 2003) and reduces information asymmetry between managers and those buying and selling stocks in the IPO firm. This article claims that IPO prospectuses, as part of the IPO market signaling event, provide an opportunity for analysts and potential investors to capture multiple dimensions of a company's corporate strategy. Against this backdrop, we suggest the following research proposition: An IPO prospectus provides a tool to signal a firm strategy type.

Signal Quality

So far, we have established an IPO event as an opportunity to signal the IPO firm's corporate strategy to the market. We now propose three indices that can be used to understand the quality of the strategy signal, namely, clarity, intensity, and consistency.

Signal clarity. Extant research finds that an effective signal should be observable and clear (Certo et al., 2001) so that market participants can easily capture the signal (Eliashberg & Robertson, 1988; Spence, 1973, 1974). This article proposes that IPO prospectuses allow IPO firms to present a corporate strategy type by stating their intention to favor one strategy type over another. If the IPO prospectus clearly states the firm's corporate strategy, the prospectus reader will quickly grasp and understand the intended corporate strategy (Heil & Robertson, 1991). Clear understanding of the firm's strategy will then encourage the investors or analysts to assess other strategic information, such as the structure of the firm and its adaptive processes (Baruch, 1992).

Signal intensity. Scholars suggest that frequently communicated signals are likely to capture the audience's attention (Riley, 1975; Spence, 1974, 2002). The audience will grasp the signals and subsequently use them to infer the firm's intended strategy type.

Signal consistency. Signal effectiveness also depends on signal consistency (Riley, 1975), which means that firms need to consistently communicate multiple signals from different dimensions and show little contradiction across dimensions. However, past IPO communication research has not investigated this aspect of signal quality; signals under investigation are typically simple, unidimensional, and focused (Certo et al., 2001; Megginson & Weiss, 1991; Neck et al., 2000). A clear and intense articulation of the firm's strategy type alone will not enhance strategy credibility; a firm also needs to show consistent evidence of a fit between strategy dimensions in order to establish strategy credibility (Miles & Snow, 1978). Therefore, this article further employs signal consistency across the dimensions of corporate strategy to examine the overall quality of corporate strategy signals-something not done in other IPO studies.

Having identified the characteristics of a credible market signal, how can a firm determine whether it has been successful in signaling corporate strategy from an IPO event? To date, a small number of studies apply signaling perspective to understand an IPO event and its performance (e.g., Carter et al., 1998; Certo et al., 2001; Megginson & Weiss, 1991; Neck et al., 2000; Rosenstein & Wyatt, 1997). Most of these studies examine the effect of IPO signals on the 1st day of initial returns (i.e., underpricing) as an indicator of whether or not market signaling has reduced information asymmetry between informed and uninformed investors (Carter et al., 1998; Certo et al., 2001; Megginson & Weiss, 1991). These studies justify the 1st-day returns based upon market efficiency theory, which suggests that the market responds immediately to information.

In this study, we work with both the 1st-day and 30-day market returns. We propose that the credible communication of corporate strategy will result in a very small gap between the offer and 1st-day price and, therefore, very little underpricing. We also propose that the three components we have identified as indicating a credible market strategy signal (clarity, intensity, and consistency) will have a negative impact on underpricing because they work to reduce information asymmetry between informed and uninformed investors. Accordingly, this study suggests the following research hypotheses:

Hypothesis 1a: The clarity of the firm's communication of its corporate strategy relates negatively to IPO underpricing on the 1st day of the IPO.

Hypothesis 1b: The intensity of the firm's communication of its corporate strategy relates negatively to IPO underpricing on the 1st day of the IPO.

Hypothesis 1c: The consistency of the firm's communication of its corporate strategy relates negatively to IPO underpricing on the 1st day of the IPO.

As previously mentioned, this study also includes the signaling effects of corporate strategy communication on returns 30 days after an IPO event for two reasons. First, opportunistic investors, who are more attracted by the potential for underpricing, might not be affected by the corporate strategy communicated in the IPO prospectus. This is especially the case for biotechnology IPOs where faddish purchasing behavior, due to overoptimism of the likely "abnormal return" from IPOs, is frequently present (Finkle & Lamb, 2002; Ritter, 1991, 1998). Second, analysts and investors may need time to read, understand, and evaluate the corporate strategy communicated in IPO prospectuses (Baruch, 1992; Bukh et al., 2002), so they will have a better understanding of the IPO value after a period of time. Therefore, the effective communication of corporate strategy might reduce 30-day initial returns by taking a slightly longer term view of underpricing. This article also investigates 30-day returns after the IPO event. This backdrop informs the following hypotheses:

Hypothesis 2a: The clarity of the firm's communication of its corporate strategy relates negatively to 30-day IPO returns.

Hypothesis 2b: The intensity of the firm's communication of its corporate strategy relates negatively to 30-day IPO returns.

Hypothesis 2c: The consistency of the firm's communication of its corporate strategy relates negatively to 30-day IPO returns.

METHOD

This article reports the findings of a single industry study: the biotechnology industry. The biotechnology industry is characterized by emerging, diverse, fast-moving, and hard-to-value products (Ranchhod, Gurau, & Lace, 2002; Weisenfeld-Schenk, 1994). Accordingly, these characteristics are likely to drive biotechnology IPO firms to employ signals in order to reduce uncertainty for investors. This research analyzes the prospectuses of 57 biotechnology IPOs, representing the entire population of biotechnology IPOs listed on the NASDAQ between 1997 and 2002.

Bhabra and Pettway (2003) find that prospectus information is more useful for predicting survival/failure compared with subsequent information. Thus, the vast majority of IPO signal studies rely on information available from prospectuses (Cohen & Dean, 2001; Daily et al., 2003; Neck et al., 2000).

The analysis includes two stages. The first stage applies content analysis, which allows us to test our research proposition that an IPO prospectus can be used to identify corporate strategy communication signals. The study applies a three-phase approach to content analysis. Phase 1 establishes 13 index variables using the Miles and Snow (1978) typology of strategy and develops operational definitions for these variables (see Table 1). This phase also includes the construction of a coding scheme (i.e., coding book, coding category table, and coding sheet). We provided a separate column in the coding sheet that allowed recording of a fourth, ambiguous signal class besides D (defender), A (analyzer), and P (prospector) for the three signal characteristics of clarity, intensity, and consistency. This coding allows for the three levels of class variables for each of the three characteristic types to be explicitly specified and tested for significance in a regression model. The fourth class, ambiguous, is appropriately confounded with the intercept, thereby eliminating unwanted linear dependence among the variables of interest.

Phase 2 includes a pilot study with two independent coders working on a subsample of IPO prospectuses to test the validity and reliability of the coding scheme developed in Phase 1. The first author of the article and an independent coder participated in the pilot coding process. The independent coder was experienced in the method of content analysis and familiar with the Miles and Snow strategy typology. The coders placed "+" on the coding sheet and entered this as "1" in the database when the coders identified an index variable from a case; otherwise, they used "-" and entered "0." Our research used the Perreault and Leigh (1989) index of reliability to test for intercoder reliability. In the first pretest, the reliability indices for the coding of two prospectuses were 62% and 73%, respectively. By comparing the coding notes, the disagreements were mainly attributed to ambiguous descriptions of operational definitions of index variables. Subsequently, the coding scheme was revised to improve the clarity of the definitions. A second pretest was then conducted to confirm the improvement in coder reliability. The reliability index was increased to 80%, which met recommended norms (Neuendorf, 2002; Perreault & Leigh, 1989). After establishing an acceptable reliability index, the coders worked independently (Perreault & Leigh, 1989).
