How Share Repurchase Signals Value: A Practitioner's Guide
How Share Repurchase Signals Value: A Practitioner's Guide
A disciplined share repurchase signals undervaluation when a company deploys excess, non-strategic cash to retire shares priced below their justified intrinsic value — and when management’s own behavior corroborates that private belief. The signal is credible only under specific conditions; absent those conditions, a buyback is a capital allocation decision, not a valuation statement.
Run these three quick filters before going deeper:
-
Funding source: Is the repurchase financed with excess free cash flow (FCF), or does it require new debt? FCF-funded programs carry the signal; debt-funded programs raise leverage and dilute the credibility of any undervaluation claim.
-
Authorization type and size: Does the board resolution specify share cancellation, or are shares held in treasury for potential reissuance? Cancellation language is a stronger commitment. Authorization size relative to market cap matters too — a program covering a very small fraction of shares outstanding rarely moves the needle on per-share intrinsic value.
-
Corroborating behavior: Are insiders buying in the open market? Is there visible takeover pressure? Has management explicitly cited valuation in earnings calls or the MD&A, rather than EPS targets?
The market’s announcement-day reaction — typically a modest positive price move — reflects approval of the cash distribution, not a confirmed revision to intrinsic value. Intrinsic-value change requires operating improvement or a genuine reduction in shares at a price below fair value. Keep those two outcomes separate from the start.

How do repurchases mechanically affect per-share metrics?
Understanding the mechanics lets you separate accounting effects from genuine value creation. Three execution structures dominate U.S. practice, each with different disclosure and timing implications.
Execution structures compared
| Structure | Execution pace | Disclosure trigger | Key risk |
|---|---|---|---|
| Open-market repurchase (OMR) | Gradual, broker-directed | 8-K at authorization; 10-Q/10-K for actual activity | Slow execution; price may drift up |
| Tender offer | Accelerated, fixed price or Dutch auction | Formal Schedule TO filing | Premium paid; signals urgency |
| Accelerated share repurchase (ASR) | Immediate share reduction, final settlement later | 8-K at launch; 10-Q for settlement | Counterparty risk; final share count uncertain |
Regulatory thresholds and procedural rules differ across structures. In the U.S., open-market programs operate under SEC Rule 10b-18 safe-harbor conditions; tender offers trigger additional Schedule TO requirements. Analysts working cross-border should note that other jurisdictions — for example, ASIC guidance in Australia — impose separate buyback procedural rules with distinct thresholds, so always confirm the governing framework for the market you are analyzing.
Mechanical effects on per-share metrics
The arithmetic is straightforward. Suppose a company repurchases a small portion of shares at a price below intrinsic value, spending an amount of cash proportionate to that portion.
| Metric | Before repurchase | After repurchase | Change |
|---|---|---|---|
| Shares outstanding | — | — | –5% |
| Net income | — | — | Unchanged |
| EPS increases purely mechanically due to fewer shares outstanding. | |||
| Book value per share | Depends on cash balance | Decreases (cash paid out) | Negative |
| Leverage (Debt/Equity) | Baseline | Higher (equity reduced) | Increases |
The EPS increase here is purely mechanical. Net income did not change; fewer shares simply divide the same earnings pool. McKinsey analysis confirms that many buybacks increase EPS this way without improving ROIC or long-run total returns. The distinction matters: if the company’s P/E multiple compresses in response to higher leverage or lower growth prospects, the EPS gain does not translate into a higher stock price.
Two channels can produce genuine economic value beyond the mechanical effect. First, if the repurchase price is below intrinsic value, continuing shareholders receive a wealth transfer from departing shareholders — accretive in a real sense. Second, returning excess cash prevents management from deploying it in low-ROIC projects, which reduces agency costs and can lower the equity risk premium over time.
Why do buybacks signal undervaluation?
The information-theoretic basis rests on a simple asymmetry: management knows more about the firm’s prospects than outside investors do. A repurchase is a costly action — cash leaves the firm — so it carries more credibility than a verbal statement about undervaluation alone.
Research identifies two distinct signaling channels: tangible-information signals, where the firm’s physical or book assets are clearly underpriced relative to replacement cost (high book-to-market), and intangible-information signals, where management believes the market underestimates future earnings power, an innovation pipeline, or intellectual property value. The second channel is harder for outside analysts to verify and therefore requires stronger corroboration.
Credibility enhancers
-
Takeover vulnerability: Firms facing genuine acquisition pressure have a strong incentive to buy shares at prices they believe are below fair value. Empirical evidence shows that repurchasing firms with higher takeover probability produce greater announcement returns and better post-announcement operating outcomes. Treat takeover pressure as a multiplicative credibility factor in your probability model.
-
Insider purchases: When the CEO or CFO buys shares in the open market concurrently with a corporate repurchase program, the two signals reinforce each other. You can track these disclosures through SEC Form 4 filings and cross-reference them against the corporate program’s 8-K authorization.
-
Management commentary: Explicit valuation language in the MD&A or earnings call transcript (“we believe our shares trade at a significant discount to intrinsic value”) is more credible than generic capital-return language. Vague references to “returning value to shareholders” carry little information content.
-
Authorization size and permanence: A large authorization with explicit cancellation language — rather than treasury repurchase — signals a genuine commitment to reducing the share count permanently.
-
Subsequent buyback announcements: Research on international markets finds that follow-up buyback announcements carry less information content than initial announcements, because they are less unexpected. A first-time program from a company that has never repurchased shares is a stronger signal than a routine renewal.
Pro Tip: When management cites a specific valuation metric — price-to-book, DCF range, or sum-of-parts — in the 8-K or earnings call, flag it. That level of specificity is rare and materially raises the posterior probability that the repurchase reflects genuine private information rather than EPS management.
The market’s response to announcement day reflects this credibility calculus. Investors revise analyst forecasts upward when corroborating signals are present and leave them flat when the repurchase appears routine or EPS-motivated.
What does the empirical literature say about buyback returns?
The U.S. evidence is more nuanced than either buyback advocates or critics typically acknowledge. Large-sample research covering more than three decades of U.S. data finds modest positive announcement-day price increases and little evidence that repurchase intensity predicts long-run total shareholder return (TRS) once ROIC and revenue growth are controlled for. The same research notes that short-term price reactions are generally persistent rather than reversed, suggesting markets do interpret some repurchases as credible signals of future prospects.
“On average, share repurchases are associated with significant positive short- and long-term excess returns. However, excess returns depend on the likelihood of undervaluation and the efficiency and liquidity of equity markets.” — Are Buybacks Good for Long-Term Shareholder Value?, ECGI study of 9,034 buyback announcements across 31 non-U.S. markets
The international evidence reinforces the U.S. findings: excess returns are significantly larger for small, beaten-up value firms with high book-to-market ratios — precisely the profile where undervaluation is most plausible. Survey evidence from the U.S. shows that 80% of managers report “stock price is too low” as a primary motivation for announcing a buyback, consistent with the market-timing hypothesis.
The practical implication: expect a short-term re-rating on the announcement. Do not infer intrinsic-value improvement unless you also see concurrent operating upgrades, analyst forecast revisions, or the corroborating governance signals described above. MIT Sloan Review analysis adds important nuance: large-sample evidence does not show systematic abuse or underinvestment from buybacks broadly, but some repurchases are clearly EPS-driven and harmful. The distinction between disciplined capital return and financial engineering is real, and the filing-level tests in the next sections are how you draw that line.
When are repurchases likely to reflect genuine undervaluation?
Not every buyback is a signal of company strength. The conditions below raise the probability that a repurchase reflects genuine undervaluation rather than cosmetic EPS management.
Financial conditions
-
High FCF relative to CapEx needs: The company generates more cash than it can deploy at attractive returns. Buyback yield (dollars repurchased divided by market cap) at a level that is material but not so large it strains the balance sheet is the right range — programs that consume more than the firm’s annual FCF warrant scrutiny.
-
Low marginal ROIC on reinvestment opportunities: When the next dollar of CapEx earns below the cost of capital, returning cash to shareholders is the value-maximizing choice. McKinsey’s analysis shows buybacks can be valuable precisely because they prevent wasteful investment — but only when the firm genuinely lacks high-ROIC reinvestment options.
-
Reasonable buyback yield: A buyback yield in the range of 2%–5% of market cap annually is common for mature U.S. companies with genuine excess cash. Yields far above that level, especially when debt-financed, often signal financial engineering rather than undervaluation.
Governance and timing conditions
-
Board-authorized cancellation (not treasury repurchase) with explicit language in the resolution.
-
Insider buying by named executives in the same period as the corporate program.
-
Visible takeover pressure or activist involvement that makes the repurchase a defensive action grounded in valuation.
-
Management commentary that references intrinsic value explicitly, not just EPS or capital-return policy.
Execution and funding conditions
-
Repurchases financed with accumulated cash or current-period FCF, not new debt issuance.
-
Execution pace consistent with open-market Rule 10b-18 parameters, spread across the quarter rather than concentrated at quarter-end.
-
No concurrent cuts to R&D or CapEx that suggest the buyback is crowding out productive investment.
Pro Tip: Cross-reference the buyback authorization date against the insider trading calendar. If the CEO filed a Form 4 purchase within 30 days of the 8-K authorization, that overlap is one of the strongest credibility signals available in public filings. You can track these disclosures using the insider and congressional trades tracker alongside the corporate program data.
What filing-level tests should analysts run in due diligence?
The workflow below is reproducible and can be automated across large cross-sections of firms. Start with the 8-K, then layer in the 10-Q and 10-K disclosures.
-
Pull the 8-K authorization. Locate the press release and the corresponding 8-K filed with the SEC. Extract: (a) total dollar or share authorization, (b) explicit cancellation vs. treasury language, © expiration date or open-ended language, and (d) any stated rationale.
-
Find the 10-Q repurchase table. The quarterly report includes an “Issuer Purchases of Equity Securities” table showing actual shares repurchased, average price paid, and remaining authorization. Compute actual buyback yield: dollars repurchased in the period divided by beginning-of-period market cap.
-
Compute net repurchase % of shares outstanding. Gross repurchases minus new share issuance (from stock compensation or convertible settlements), divided by beginning shares outstanding. A positive net figure means the share count is actually declining.
-
Check FCF coverage. Divide total repurchase spend by trailing-twelve-month free cash flow (operating cash flow minus CapEx). A ratio above 1.0x means the company is spending more on buybacks than it generates in FCF — a red flag unless the balance sheet carries substantial excess cash.
-
Analyze CapEx and R&D trends. Pull the CapEx and R&D lines from the 10-K or 10-Q and compare year-over-year. Concurrent cuts alongside a new buyback program are a warning sign of EPS-motivated financial engineering.
-
Check insider trades. Review Form 4 filings for the CEO, CFO, and board members in the 60 days surrounding the authorization. Net open-market purchases corroborate the undervaluation signal; net sales undercut it.
-
Run the EPS-motivation screen. Compare the firm’s reported EPS against the consensus analyst estimate for the same period. Regression discontinuity evidence shows that firms which would otherwise miss EPS forecasts increase repurchases and subsequently reduce CapEx, R&D, and employment. If the firm just cleared the consensus by a penny and repurchased heavily in the same quarter, flag it.
Metrics and formulas reference
| Metric | Formula | Source field in filings |
|---|---|---|
| Buyback yield | Dollars repurchased / market cap | 10-Q “Issuer Purchases” table |
| Net repurchase % | (Gross repurchases – share issuance) / shares outstanding | 10-Q cash flow statement + equity rollforward |
| FCF coverage ratio | Repurchase spend / (Operating CF – CapEx) | 10-Q/10-K cash flow statement |
| Change in ROIC | (NOPAT / Invested capital) current vs. prior year | 10-K income statement + balance sheet |
| Per-share DCF adjustment | Intrinsic value per share × (1 – repurchase %) | Internal model, calibrated to 10-K disclosures |
Pro Tip: Automated filing extraction reduces the time to compute these metrics from hours to minutes across a broad universe of names. Platforms that parse 8-K authorization language and map it to the 10-Q repurchase table let you run the FCF coverage and EPS-motivation screens at scale — the kind of red-flag detection that is impractical to do manually across a large portfolio.
How do you model a buyback’s effect on intrinsic value?
Two practical approaches let you convert a repurchase into an incremental per-share valuation impact.
Approach A: Per-share DCF adjustment
Reduce shares outstanding in your DCF model by the net repurchase percentage. If the firm repurchases 5% of shares at a price below your estimated intrinsic value, the remaining shares are worth more — the wealth transfer is real and quantifiable. The key sensitivity is the gap between your intrinsic value estimate and the repurchase price. A buyback at 80% of intrinsic value creates a 1.25% per-share gain for every 5% of shares retired; a buyback at 110% of intrinsic value destroys value for continuing shareholders.
Adjust the discount rate modestly if the repurchase materially changes the capital structure. Higher leverage raises the cost of equity; if the firm is moving from a net-cash position to a levered one, your WACC should reflect that shift.
Approach B: EPS accretion arithmetic
The mechanical EPS accretion formula is: new EPS = old EPS / (1 – repurchase %). The accretion is real only if the P/E multiple holds or expands. If the market re-rates the stock downward because of higher leverage or lower growth expectations, the EPS gain is offset. McKinsey’s consulting analysis shows that when a firm earns a high ROIC on reinvested capital, investing rather than repurchasing creates more value — the accretion math only favors buybacks when reinvestment returns are below the cost of capital.
Scenario framework
-
Bull case: Repurchase at a material discount to intrinsic value, FCF improves, ROIC on remaining invested capital rises. Model the full per-share DCF gain plus multiple expansion.
-
Base case: Repurchase at fair value, FCF stable, ROIC unchanged. Model only the mechanical EPS accretion; assume the P/E multiple compresses proportionally. Net per-share value change is approximately zero.
-
Bear case: Repurchase funded by debt, ROIC on new projects declines, leverage rises. Model the higher cost of equity and potential multiple compression. Per-share value may decline even as EPS rises.
Present these as probability-weighted scenarios rather than a single point estimate. The weight you assign to the bull case should increase with each corroborating signal: insider buying, takeover pressure, explicit valuation commentary, and strong FCF coverage.
What do authorization wording and insider activity reveal?
The 8-K and proxy statement contain the most direct evidence of management’s intent. Read them with these specific questions in mind.
-
Cancellation vs. treasury: Does the authorization state that repurchased shares will be retired and cancelled, or held as treasury shares for potential reissuance? Cancellation is the stronger commitment. Treasury shares can be reissued for stock compensation or acquisitions, which partially offsets the per-share benefit.
-
Authorization size: A program authorizing 10% or more of shares outstanding is a material commitment. Smaller programs (under 2%) may reflect routine offset of stock-based compensation dilution rather than a genuine undervaluation signal.
-
Expiration and pace: Open-ended authorizations with no expiration date give management flexibility but reduce urgency. A defined timeline with a stated pace suggests genuine conviction.
-
Funding source language: Look for phrases like “funded from existing cash and cash equivalents” versus “may include proceeds from debt issuance.” The latter is a yellow flag that warrants a leverage check.
-
Board minutes and proxy discussion: If the proxy statement or a 10-K footnote discusses the board’s valuation rationale for the repurchase, that disclosure is unusually informative. Most boards do not publish their deliberations; when they do, it is worth reading carefully.
On insider behavior: Form 4 filings are public and searchable on the SEC’s EDGAR system. A CEO who purchases shares in the open market within 30 days of a corporate buyback authorization is putting personal capital behind the same thesis. That overlap is one of the strongest double-signals available. Conversely, if executives are selling shares under a 10b5-1 plan while the company repurchases, the signals conflict and the corporate program’s credibility weakens.
Activist or takeover pressure adds a third layer. A firm that announces a buyback while facing an activist campaign or a known acquirer’s interest has a concrete, external reason to believe its shares are underpriced. The credibility of the signal is materially higher in that context than for a routine capital-return announcement.
What are the warning signs that a buyback is cosmetic?
Several patterns consistently indicate that a repurchase is driven by EPS management or short-term optics rather than genuine undervaluation.
-
EPS-just-miss timing: The firm reported EPS that would have missed the consensus estimate without the buyback. Regression discontinuity research identifies this pattern clearly: firms that just clear the consensus through repurchases subsequently cut CapEx, R&D, and employment. The buyback is not a signal of undervaluation; it is a signal of earnings pressure.
-
Debt-financed repurchases with no ROIC improvement plan: Borrowing to buy back shares raises leverage without improving operating performance. Unless the firm has a credible path to ROIC improvement that justifies the higher cost of equity, this structure destroys value for long-term holders.
-
Quarter-end concentration: If the 10-Q repurchase table shows that the vast majority of activity occurred in the final two weeks of the quarter, the timing is suspicious. Quarter-end concentration often reflects an effort to hit EPS or book-value-per-share targets rather than opportunistic buying at attractive prices.
-
Tender offer timing coinciding with compensation cliffs: A tender offer launched just before a large executive equity grant vests can inflate the stock price at a convenient moment. Check the proxy statement for vesting schedules alongside tender offer timing.
-
Concurrent cuts to productive investment: Any buyback accompanied by material reductions in R&D or growth CapEx in the same period warrants a red flag. The accounting red flags framework applies here: a firm that is harvesting its balance sheet to support short-term metrics is not signaling undervaluation.
-
No insider buying: A company that announces a buyback while no named executive purchases shares in the open market is sending a mixed message. The absence of insider buying does not disqualify the signal, but its presence would strengthen it considerably.
How does filing-level evidence improve signal credibility?
The research converges on a consistent finding: announcement returns are modest on average, but the distribution is wide. The firms in the upper tail — those with the strongest long-run outcomes — share a common profile: they repurchased under takeover pressure or with corroborating operating improvements, and their filing disclosures reflected genuine conviction rather than routine capital-return language.
-
Announcement returns: Large-sample U.S. evidence finds modest positive announcement-day price increases that generally do not reverse, suggesting markets interpret at least some repurchases as credible signals. But the average masks significant dispersion.
-
Long-run TRS: Large-sample research finds weak correlation between repurchase intensity and long-run TRS once ROIC and revenue growth are controlled for. Repurchase intensity alone is not a reliable predictor of outperformance.
-
Takeover pressure as a multiplier: Firms facing higher takeover probability show stronger announcement returns and better long-run operating outcomes. This is the single most powerful credibility enhancer in the empirical literature.
-
Filing-level signals raise posterior probability: Authorization wording (cancellation vs. treasury), funding-source language, insider trade timing, and contemporaneous operating news each independently increase the probability that a repurchase reflects genuine undervaluation. Stacking multiple signals is more powerful than any single indicator.
-
Underreaction opportunity: Research on market underreaction to repurchase signals suggests that when a disciplined repurchase reduces agency costs and investors underprice the longer-term risk reduction, a genuine alpha opportunity exists for analysts who identify the full signal stack early.
Automated extraction of filing language materially reduces the time between a repurchase announcement and a fully scored signal. Pulling authorization wording, funding-source fields, insider trade data, and time-series metrics from 8-Ks and 10-Qs programmatically allows reproducible computation of buyback yield and net repurchase percentage across large cross-sections of firms — the kind of systematic approach that is difficult to replicate manually.
How should you translate a buyback signal into a portfolio action?
The decision framework has three states: add, monitor, or avoid.
Add (probability-weighted undervaluation with operating corroboration)
-
Buyback funded by excess FCF, not debt.
-
Authorization specifies cancellation; size is material relative to market cap.
-
At least two corroborating signals present: insider buying, takeover pressure, explicit valuation commentary, or concurrent operating improvement.
-
FCF coverage ratio above 1.0x; ROIC on new projects below cost of capital (excess cash genuinely exists).
-
EPS-motivation screen is clean: the firm was not at risk of missing consensus before the repurchase.
For position sizing, apply a risk-to-reward framework calibrated to the probability-weighted intrinsic value gap. A buyback at a 20% discount to your DCF estimate with three corroborating signals warrants a larger position than one at a 5% discount with a single signal.
Monitor (announcement only, no corroborating fundamentals)
-
Repurchase announced but no insider buying, no takeover pressure, and management commentary is generic.
-
FCF coverage is adequate but not exceptional.
-
No concurrent operating improvement visible in the most recent 10-Q.
Hold the position if you already own the stock; do not add on the announcement alone. Set a re-evaluation trigger: if insider buying or an operating catalyst appears within 60 days, upgrade to add.
Avoid (debt-funded, EPS-motivated, or red-flag pattern)
-
Repurchase financed with new debt and no credible ROIC improvement plan.
-
EPS-motivation screen flags the firm as a just-miss candidate.
-
Concurrent cuts to R&D or CapEx visible in the 10-Q.
-
Insider selling concurrent with the corporate program.
Timing note: open-market programs typically execute over 12–24 months; tender offers complete in weeks. The announcement re-rating is fastest for tender offers and ASRs. For open-market programs, the fundamental improvement — if it materializes — takes quarters to show up in operating metrics. Set your time horizon accordingly, and define a stop-loss or re-evaluation trigger at the point where FCF or ROIC data from the next 10-Q contradicts the original thesis.
Key Takeaways
A share repurchase signals genuine undervaluation only when funded by excess FCF, authorized for cancellation, and corroborated by insider buying, takeover pressure, or explicit valuation commentary from management.
| Point | Details |
|---|---|
| FCF funding is the first filter | Repurchases financed with excess free cash flow carry the signal; debt-funded programs raise leverage and reduce credibility. |
| Cancellation beats treasury | Board authorization specifying share cancellation is a stronger commitment than treasury repurchase, which allows reissuance. |
| ROIC matters more than EPS accretion | Mechanical EPS gains do not improve long-run TRS unless ROIC on remaining invested capital also improves. |
| Takeover pressure multiplies credibility | Firms repurchasing under genuine acquisition pressure show stronger announcement returns and better post-announcement operating outcomes. |
| Filingsiq accelerates the signal stack | Filingsiq extracts authorization language, funding-source fields, and insider trade data from 8-Ks and 10-Qs, enabling reproducible computation of buyback yield and FCF coverage across large portfolios. |
The real story behind buyback signals
The most common mistake analysts make with repurchase signals is treating EPS accretion as a proxy for value creation. It is not. A company can mechanically boost EPS every quarter for years through buybacks while its underlying ROIC quietly deteriorates and its competitive position erodes. The EPS line looks healthy; the business does not.
The habit worth building is this: every time you see a buyback announcement, run the FCF coverage ratio and the ROIC trend before you do anything else. If FCF coverage is below 1.0x or ROIC on new projects is rising (meaning the firm actually has good reinvestment options it is passing up), the repurchase deserves skepticism regardless of how the stock reacts on announcement day. If both checks pass, then layer in the governance signals: cancellation language, insider buying, and management commentary. That sequence keeps you from being anchored by the market’s initial reaction.
One practical habit that pays off: set a weekly alert for 8-K filings that contain both repurchase authorization language and a Form 4 insider purchase from the same company within a 30-day window. That overlap is rare enough to be meaningful and common enough to generate a steady flow of candidates worth investigating. The filing-level evidence is all public; the edge comes from reading it systematically rather than reactively.
Filingsiq speeds up every step of buyback due diligence
The checklist in this article — authorization wording, funding-source language, FCF coverage, insider trade timing, EPS-motivation screen — requires pulling data from multiple SEC filings and computing several metrics per name. Done manually, that process takes hours per company. Done at scale across a portfolio or screening universe, it is impractical without automation.
Filingsiq extracts authorization language, funding-source fields, and insider trade disclosures directly from 8-Ks, 10-Qs, and 10-Ks, and maps them to the time-series metrics the tests above require. The platform’s AI-powered summaries surface the specific filing language that matters — cancellation vs. treasury wording, debt-issuance proceeds language, concurrent CapEx changes — so you spend your time on judgment, not document retrieval. If you are running buyback signal analysis across more than a handful of names, the Filingsiq platform cuts research time materially and makes the reproducible tests above practical at any portfolio scale. See how it works or review pricing and plans to find the right tier for your workflow.

FAQ
How does a share buyback create value for investors?
A buyback creates value when shares are repurchased below intrinsic value, transferring wealth to continuing shareholders, and when it prevents management from deploying excess cash in low-ROIC projects. The mechanical EPS increase alone does not create value unless the P/E multiple holds and operating performance improves.
How do you value the impact of a share repurchase?
Reduce shares outstanding in your DCF model by the net repurchase percentage and compare the repurchase price to your intrinsic value estimate. If the firm buys at a discount to intrinsic value, the per-share gain equals the discount multiplied by the repurchase fraction; if it buys above intrinsic value, continuing shareholders lose on a per-share basis.
What metrics should analysts compute first when screening buybacks?
Start with FCF coverage (repurchase spend divided by trailing FCF) and buyback yield (dollars repurchased divided by market cap). Then check the authorization for cancellation language and run the EPS-motivation screen by comparing reported EPS against the pre-repurchase consensus estimate.
What is the difference between a repurchase signal and a dividend signal?
Dividends are a recurring commitment that management is reluctant to cut, making them a signal of sustainable earnings. Repurchases are more flexible and discretionary, which makes them a stronger signal of current undervaluation when management has private information about near-term prospects. The flexibility that makes repurchases useful for signaling also makes them easier to misuse for EPS management.
How does takeover pressure affect the credibility of a buyback signal?
Firms repurchasing under genuine acquisition pressure have a concrete external reason to believe their shares are underpriced, which makes the signal substantially more credible. Empirical evidence shows these firms produce stronger announcement returns and better post-announcement operating outcomes than firms repurchasing without such pressure.
