The Takeover Code is, at bottom, a machine that asks one question: when must a person who is buying into a listed company stop and make an open offer to the public shareholders? Every working part of that machine is bolted to three definitions in Regulation 2(1) of the SEBI (Substantial Acquisition of Shares and Takeovers) Regulations, 2011 — the acquirer who buys, the persons acting in concert (PAC) whose holdings are clubbed with his, and the target company whose shareholders the Code protects. Misread any one of them and the trigger thresholds, the open-offer obligation and the disclosure regime all misfire. This note unpacks each definition against its bare text and the leading authorities — Daiichi Sankyo Co. Ltd. v. Jayaram Chigurupati on the meaning of "acting in concert", Technip SA v. SMS Holding (P) Ltd. on acquisition of control, and the celebrated Subhkam Ventures ruling on what "control" really means. Because acquirer, PAC and control are interlocking, the related concept of control under Regulation 2(1)(e) is treated alongside them throughout.

Why the Definitions Decide Everything

The SAST Regulations, 2011 replaced the 1997 Code on the recommendations of the Achuthan Committee, but they retained the original architecture: a person who crosses prescribed shareholding thresholds, or who acquires control, must make a public open offer to the remaining shareholders so that they can exit at a fair price. The substantive triggers live in Regulation 3 (the 25% and creeping-acquisition thresholds) and Regulation 4 (acquisition of control), and the consequences flow through Regulations 5 to 22. But none of those operative provisions can even be read without first fixing the three nouns they all use: who is the acquirer, who are the persons acting in concert with him, and what is the target company.

The reason the definitions carry so much weight is that the thresholds are computed on a collective basis. Regulation 3 speaks of shares or voting rights acquired by an acquirer "together with persons acting in concert with him". A buyer who personally holds only 12% may still cross the 25% line if his PAC hold another 14%. Conversely, two co-operating buyers who are wrongly treated as PAC may be saddled with an open-offer obligation that the Code never intended. The definitional questions are therefore not academic — they decide liability. For the threshold mechanics themselves, see substantial acquisition and the 25% threshold and the trigger for an open offer.

A second structural point: the Code defines acquirer, PAC and target company expansively and on a "deeming" basis, precisely because takeovers are engineered to slip through narrow definitions. Indirect acquisitions, layered holding structures and concert parties are the norm, not the exception. The definitions are drafted to catch substance over form, and the courts have read them in that spirit.

Acquirer — Regulation 2(1)(a)

Regulation 2(1)(a) defines an "acquirer" as any person who, directly or indirectly, acquires or agrees to acquire whether by himself, or through, or with persons acting in concert with him, shares or voting rights in, or control over a target company. Five features of this definition repay close reading.

First, the subject is "any person" — an individual, a company, a body corporate, a partnership, a trust or any other entity. Second, the conduct caught is both acquiring and agreeing to acquire; an executed agreement to acquire can trigger obligations even before delivery of shares. Third, the acquisition may be direct or indirect — buying the holding company that in turn holds the listed target is as much an acquisition as buying the target's shares directly, a point central to Technip SA v. SMS Holding and to the law on indirect acquisition. Fourth, the acquisition may be by himself or through or with PAC — so the acquirer's own holding is never read in isolation. Fifth, the object of the acquisition is stated in the alternative: shares, voting rights, OR control. Acquisition of control alone, even without crossing a numerical share threshold, makes a person an acquirer and can trigger an open offer under Regulation 4.

The breadth is deliberate. A person never becomes an acquirer by accident of nomenclature; he becomes one by what he does — acquiring or agreeing to acquire shares, votes or control in a listed company. The definition is the gateway: only once a person answers this description do the threshold and open-offer provisions even begin to apply to him.

Direct and Indirect Acquisition Within the Definition

The words "directly or indirectly" in Regulation 2(1)(a) are the textual hook for the entire law of indirect takeovers. An acquirer who gains shares, voting rights or control over the target by acquiring some other entity — typically an unlisted holding or parent company sitting above the listed target — is treated as having acquired the target itself. The leading illustration is Technip SA v. SMS Holding (P) Ltd., (2005) 5 SCC 465, decided under the 1997 Code but squarely relevant to the 2011 definition.

In Technip, the French company Coflexip held, through a chain of subsidiaries, about 49.85% of SEAMEC, an Indian listed company. Technip, also French, later acquired the controlling block in Coflexip. SEBI took the view that by acquiring Coflexip, Technip had indirectly acquired control over SEAMEC and was obliged to make an open offer. The Supreme Court accepted the principle of indirect acquisition but held that the date on which control over Coflexip — and hence indirectly over SEAMEC — was acquired had to be determined by the law of domicile of the two French companies, namely French law, because their inter se relationship was one of status. On the facts, the Court fixed the date of acquisition of control as July 2001 (not April 2000), with significant consequences for the open-offer price. The case confirms that acquiring an upstream company is, for the purposes of the acquirer definition, an acquisition of the downstream listed target.

The 2011 Regulations now codify this in Regulation 5, distinguishing acquisitions that are deemed "direct" from those treated as genuinely "indirect", with timing and pricing rules attached. But the conceptual root remains the single phrase "directly or indirectly" in the acquirer definition. The detailed treatment is at indirect acquisition.

Persons Acting in Concert — Regulation 2(1)(q)

Regulation 2(1)(q) defines "persons acting in concert" in two parts. The general limb — Regulation 2(1)(q)(1) — provides that PAC means persons who, with a common objective or purpose of acquisition of shares or voting rights in, or exercising control over a target company, pursuant to an agreement or understanding, formal or informal, directly or indirectly co-operate for acquisition of shares or voting rights in, or exercise of control over the target company. Three ingredients emerge: (i) a common objective or purpose of acquiring shares, votes or control; (ii) an agreement or understanding, which may be formal or informal; and (iii) actual co-operation, direct or indirect, towards that end.

The genius — and the difficulty — of the definition lies in the words "agreement or understanding, formal or informal". A concert party rarely reduces its arrangement to a signed document; the Code therefore reaches tacit understandings inferred from conduct. But the common object must be referable to a specific target company. People may co-operate for any number of business purposes; they become PAC only when the shared purpose is the acquisition of shares, voting rights or control over the particular target in question. This is the point the Supreme Court drove home in Daiichi Sankyo v. Jayaram Chigurupati, discussed below.

Why does clubbing matter? Because once two persons are PAC, their individual holdings are aggregated for every threshold in Regulation 3. A finding of concert can convert two innocuous minority stakes into a collective controlling block that triggers a mandatory open offer.

Deemed Persons Acting in Concert

The second limb — Regulation 2(1)(q)(2) — sets out categories of persons who are deemed to be acting in concert with one another, unless the contrary is established. The deeming is a rebuttable presumption: the relationship is assumed, but a party may lead evidence to show that the common objective of acquiring the target was absent. The enumerated categories include, among others: (i) a company, its holding company, subsidiary company and any company under the same management or control; (ii) a company, its directors, and any person entrusted with the management of the company; (iii) directors of companies referred to above, and associates of such directors; (iv) promoters and members of the promoter group; (v) immediate relatives; (vi) a mutual fund, its sponsor, trustees, trustee company and asset management company; (vii) a collective investment scheme and its collective investment management company, trustees and trustee company; (viii) an alternative investment fund and its sponsor, trustees, trustee company and manager; (ix) merchant bankers and acquirers where the merchant banker acts in that capacity for the acquirer; (x) a portfolio manager and its client who is the acquirer; and (xi) banks, financial advisors and stockbrokers of the acquirer or of a company under the same management, in connection with the obligations under the Code.

The crucial qualifier is the chapeau: persons in these categories are deemed PAC unless the contrary is established. So the holding-subsidiary or promoter-group relationship raises the presumption, but the burden then shifts to the parties to rebut it by showing no shared acquisition objective. This rebuttable character was decisive in Daiichi Sankyo, where a holding-subsidiary link arising after the relevant acquisition could not retrospectively make the parties concert parties.

For the student, the practical drill is: first ask whether the parties fall within a deemed category; if so, treat them as PAC unless the facts rebut the presumption; if not, fall back to the general limb and ask whether a common objective, an understanding and co-operation can be proved.

Daiichi Sankyo v. Jayaram Chigurupati — The PAC Test

The locus classicus on "persons acting in concert" is Daiichi Sankyo Co. Ltd. v. Jayaram Chigurupati, (2010) 7 SCC 449, decided on 8 July 2010 under the 1997 Code. Daiichi, a Japanese pharmaceutical company, acquired the promoters' controlling stake in Ranbaxy Laboratories, an Indian listed company. Ranbaxy in turn held shares in Zenotech Laboratories, another listed company. The dispute was over the open-offer price for Zenotech: the objectors argued that Daiichi and Ranbaxy were PAC, so that Ranbaxy's earlier purchases of Zenotech shares at a higher price (about Rs. 160) had to be factored into Daiichi's offer price (about Rs. 113.62), rather than ignored.

The Supreme Court rejected the argument. Justice Aftab Alam, writing for the Court, held that the expression "persons acting in concert" connotes more than a mere relationship; it requires a shared common objective or purpose of substantial acquisition of shares of the target company. The Court laid down the now-classic formulation: "Two or more persons may join hands together with the shared common objective or purpose of any kind but so long as the common object and purpose is not of substantial acquisition of shares of a target company they would not comprise persons acting in concert." The shared common objective, the Court said, is the sine qua non of the relationship.

Applying this, the Court held that at the time Ranbaxy made its acquisitions in Zenotech, Daiichi and Ranbaxy were independent and unconnected; the holding-subsidiary relationship between them came into being only later, when Daiichi acquired Ranbaxy. A relationship that arises after the relevant acquisition cannot retrospectively brand the parties as concert parties for that earlier acquisition. Daiichi and Ranbaxy were therefore not PAC vis-a-vis Zenotech at the material time, and Ranbaxy's earlier higher-priced purchases did not have to be reckoned in Daiichi's offer price.

The Two-Fold Lesson of Daiichi Sankyo

Daiichi Sankyo yields two enduring propositions. First, the common objective must be referable to the specific target company and must be the objective of substantial acquisition of that target's shares or control. Persons who co-operate for some other business purpose, however closely, are not PAC for takeover purposes. The mere existence of a holding-subsidiary or group relationship is not enough; there must be a shared acquisition objective directed at the target.

Second, the deemed-PAC categories in the definition operate as a rebuttable presumption tied to a point in time. The Court read the deeming provision harmoniously with the general definition: even a holding company and its subsidiary are PAC only when they share the common object of acquiring the target, and the relationship must exist at the relevant time of acquisition. A relationship that crystallises afterwards cannot be projected backwards. This reading prevents the deeming categories from sweeping in genuinely independent acquisitions merely because the parties later became related.

For the exam, Daiichi is the answer to any question on the meaning of PAC: state the three ingredients of the general limb, note the rebuttable deeming categories, and then deploy the "shared common objective of substantial acquisition of the target" test as the controlling principle, with the timing point as the rider. The case is also frequently paired with the law on indirect acquisition, since the underlying transaction was itself an indirect acquisition of Zenotech through Ranbaxy.

Target Company — Regulation 2(1)(z)

Regulation 2(1)(z) defines a "target company" as a company and includes a body corporate or corporation established under a Central legislation, State legislation or Provincial legislation for the time being in force, whose shares are listed on a stock exchange. Two elements are essential. First, the entity must be a company or a body corporate/corporation established under a statute. Second — and this is the gatekeeper — its shares must be listed on a stock exchange.

Listing is the jurisdictional fact. The entire object of the Takeover Code is to protect public shareholders who acquire shares on the market and who, on a change of control, deserve an exit opportunity. Where there are no public shareholders trading on an exchange, the policy has nothing to protect. Hence an unlisted company, however large, is not a target company, and its acquisition does not attract the open-offer machinery — although, as Technip shows, acquiring an unlisted company can amount to an indirect acquisition of a listed company sitting below it, which does fall within the Code.

The inclusion of statutory corporations and bodies corporate ensures that the definition is not confined to companies registered under the Companies Act; any listed body corporate established under Central, State or Provincial law qualifies. But the listing requirement remains the indispensable filter that marks out the universe of companies to which the Code applies.

Control — Regulation 2(1)(e)

Because the acquirer definition expressly reaches the acquisition of control, the meaning of "control" is inseparable from these definitions. Regulation 2(1)(e) provides that "control" includes the right to appoint majority of the directors or to control the management or policy decisions exercisable by a person or persons acting individually or in concert, directly or indirectly, including by virtue of their shareholding or management rights or shareholders agreements or voting agreements or in any other manner. A proviso clarifies that a director or officer of a target company shall not be considered to be in control over such target company merely by virtue of holding such position.

The definition is inclusive, not exhaustive, and has two distinct facets. The first is de jure control — the right to appoint a majority of the board, a bright-line, structural test. The second is de facto control — the ability to control the management or policy decisions of the company, by whatever means: shareholding, management rights, shareholders' agreements, voting agreements, or "in any other manner". The open-ended residuary phrase is what makes control hard to pin down: control can arise from a web of contractual rights even where no single shareholder holds a majority of shares or board seats.

Acquisition of control independently triggers an open offer under Regulation 4, regardless of the quantum of shares acquired. This is why a private-equity investor who takes a small equity stake but bargains for extensive governance rights must ask whether those rights cross the line from protection into control. That question was the heart of Subhkam Ventures.

Subhkam Ventures — Positive Control versus Negative Protection

The most influential analysis of "control" is the Securities Appellate Tribunal's decision in Subhkam Ventures (I) (P) Ltd. v. SEBI, decided on 15 January 2010 under the 1997 Code. Subhkam, a private-equity investor, acquired about 17.9% in MSK Projects (India) Ltd. and, through a shareholders' agreement, secured certain rights: nominee directors, and affirmative voting items (vetoes) over major corporate actions such as changes in capital structure, amendments to the memorandum and articles, and significant disposals. SEBI took the view that these rights amounted to "control", obliging Subhkam to make an open offer.

The SAT disagreed. It drew a now-famous distinction between proactive (positive) control and reactive (negative) control. "Control," the Tribunal held, "is a proactive and not a reactive power. It is a power by which an acquirer can command the target company to do what he wants it to do." Control means the power to drive the company — to take the initiative and steer its management and policy. By contrast, affirmative or veto rights that merely allow an investor to block certain extraordinary actions are protective in nature; they let the investor guard its investment but do not enable it to command the company's affairs. Such negative, protective rights, the SAT held, do not amount to control within the meaning of the Code.

On that reasoning, the SAT set aside SEBI's direction: the affirmative-vote rights Subhkam had bargained for were protective covenants of the kind common in private-equity deals and did not constitute acquisition of control. The decision was widely welcomed by investors because it reconciled standard PE protective rights with the Takeover Code.

The Supreme Court's Disposal and the Lingering Uncertainty

SEBI appealed the SAT's ruling to the Supreme Court. In 2011, the appeal was disposed of by consent — Subhkam had by then divested its stake, rendering the dispute academic. Crucially, the Supreme Court expressly kept the question of law open and directed that the SAT's order "will not be treated as a precedent". The result is a peculiar one for students to note: the proactive-versus-reactive distinction is intellectually compelling and remains highly influential in practice, but it does not enjoy binding precedential status, because the very order articulating it was stripped of precedent value by the Supreme Court.

The consequence is continuing uncertainty about where protective rights end and control begins. SEBI itself floated a discussion paper in 2016 proposing brighter-line and framework-based tests for control, but no bright-line numerical definition was ultimately adopted, and Regulation 2(1)(e) retains its open-textured "in any other manner" formulation. The fact-sensitive inquiry therefore survives: a court or the Board must look at the totality of an investor's rights and ask whether, in substance, the investor can command the company or can merely protect its position.

For examination purposes, the safe statement is: Subhkam established the proactive/reactive distinction at the SAT level; the Supreme Court left the question of law open and denied the order precedential value; and the test for control under Regulation 2(1)(e) remains substance-based and fact-specific, with acquisition of control independently triggering an open offer under Regulation 4. This connects directly to the discussion of the trigger for an open offer.

How the Three Definitions Interlock

The three definitions are not silos; they operate as a single interlocking test. Start with the target company — is the entity one whose shares are listed on a stock exchange? If not, the Code does not apply (subject to the indirect-acquisition route). If yes, ask who the acquirer is — any person who, directly or indirectly, acquires or agrees to acquire shares, voting rights or control over that listed company. Then identify the persons acting in concert with the acquirer, because their holdings are clubbed with his for every threshold computation.

The clubbing is where the definitions bite hardest. Under Regulation 3, an acquirer "together with persons acting in concert" crossing 25% of shares or voting rights triggers a mandatory open offer; the creeping-acquisition allowance and the various exemptions all operate on the combined PAC holding. Acquisition of control — as defined in Regulation 2(1)(e) and litigated in Subhkam — independently triggers an offer under Regulation 4, even below the numerical thresholds. A complete analysis of any takeover problem therefore runs: target company (listed?) → acquirer (who is buying, directly or indirectly?) → PAC (whose holdings are clubbed?) → quantum of shares/votes and/or control acquired → open-offer obligation.

Common Errors and Examiner Traps

Several recurring errors are worth flagging. First, students often treat the deemed-PAC categories as conclusive. They are not — Regulation 2(1)(q)(2) operates "unless the contrary is established", and Daiichi Sankyo confirms that even a holding-subsidiary relationship can be rebutted by showing the absence of a shared acquisition objective at the relevant time. Second, candidates sometimes assume that any large investor's protective rights amount to control; Subhkam teaches that veto or affirmative-vote rights that merely protect an investment, without the power to command the company, are negative rights that do not constitute control — though they must always be assessed on the totality of facts.

Third, the listing requirement in the target-company definition is frequently overlooked. The Code simply does not apply to the direct acquisition of an unlisted company; but acquiring an unlisted parent can be an indirect acquisition of a listed subsidiary, as Technip illustrates. Fourth, do not forget that acquisition of control alone — without any numerical share threshold being crossed — makes a person an acquirer and triggers an open offer under Regulation 4. Finally, on Subhkam, the precise and frequently-tested point is that the Supreme Court kept the question of law open and held the SAT order is not a precedent; stating it as binding authority is an error.

Mastering these traps means stating each definition with its qualifiers — "directly or indirectly", "agreement or understanding, formal or informal", "unless the contrary is established", "includes... or in any other manner" — rather than the bare skeleton, and pairing each with its controlling authority.

Key Takeaways for the Exam

Reduced to essentials: an acquirer under Regulation 2(1)(a) is any person who, directly or indirectly, by himself or with PAC, acquires or agrees to acquire shares, voting rights or control over a target company. Persons acting in concert under Regulation 2(1)(q) are those who, with a common objective of acquiring shares, votes or control over a specific target, pursuant to a formal or informal agreement or understanding, co-operate to that end; certain categories (holding-subsidiary, promoter group, mutual fund and its AMC, AIF and its sponsor, and others) are deemed PAC unless the contrary is established. A target company under Regulation 2(1)(z) is a company or statutory body corporate whose shares are listed on a stock exchange — listing being the indispensable jurisdictional fact.

On the authorities: Daiichi Sankyo Co. Ltd. v. Jayaram Chigurupati, (2010) 7 SCC 449, holds that a shared common objective of substantial acquisition of the target is the sine qua non of acting in concert, and that the deeming presumption is time-bound and rebuttable. Technip SA v. SMS Holding (P) Ltd., (2005) 5 SCC 465, confirms that indirect acquisition through an upstream company is caught, and fixes the date of acquisition of control by reference to applicable law. Subhkam Ventures (I) (P) Ltd. v. SEBI (SAT, 15 January 2010) draws the proactive/reactive line on control, but the Supreme Court disposed of the appeal by consent, kept the question of law open, and held that the SAT order is not a precedent. Hold these three definitions and three cases together, and the operative provisions on the 25% threshold and the open-offer trigger fall into place.

Frequently asked questions

Who is an "acquirer" under the SEBI Takeover Code, 2011?

Under Regulation 2(1)(a), an acquirer is any person who, directly or indirectly, acquires or agrees to acquire — whether by himself, or through, or with persons acting in concert with him — shares or voting rights in, or control over, a target company. The definition is deliberately broad: it covers individuals and entities, executed and agreed acquisitions, direct and indirect routes, and reaches acquisition of control even without a share threshold being crossed.

What does "persons acting in concert" mean and why does it matter?

Regulation 2(1)(q) defines PAC as persons who, with a common objective of acquiring shares, voting rights or control over a target company, pursuant to a formal or informal agreement or understanding, directly or indirectly co-operate to that end. It matters because the holdings of PAC are clubbed with the acquirer's for every threshold in Regulation 3. In Daiichi Sankyo v. Jayaram Chigurupati, (2010) 7 SCC 449, the Supreme Court held that a shared common objective of substantial acquisition of the target is the sine qua non of acting in concert.

Are the "deemed" PAC categories conclusive?

No. Regulation 2(1)(q)(2) lists categories — such as a company and its holding/subsidiary, promoters and the promoter group, a mutual fund and its AMC, and an AIF and its sponsor — but they are deemed to be acting in concert only "unless the contrary is established". The presumption is rebuttable. In Daiichi Sankyo, the Court held that a holding-subsidiary relationship arising after the relevant acquisition could not retrospectively make the parties concert parties, because the shared acquisition objective was absent at the material time.

What makes a company a "target company"?

Under Regulation 2(1)(z), a target company is a company, or a body corporate or corporation established under Central, State or Provincial legislation, whose shares are listed on a stock exchange. Listing is the jurisdictional fact: the Code protects public shareholders trading on an exchange, so an unlisted company is not a target company. However, acquiring an unlisted parent may amount to an indirect acquisition of a listed subsidiary, as in Technip SA v. SMS Holding, (2005) 5 SCC 465.

How is "control" defined, and what did Subhkam Ventures decide?

Regulation 2(1)(e) inclusively defines control as the right to appoint a majority of directors or to control the management or policy decisions, by shareholding, management rights, shareholders' or voting agreements, or in any other manner. In Subhkam Ventures (I) (P) Ltd. v. SEBI (SAT, 15 January 2010), the Tribunal held that control is a proactive, not a reactive, power — the ability to command the company, not merely to block it. Protective veto rights were held not to constitute control. Note, however, that the Supreme Court disposed of SEBI's appeal by consent, kept the question of law open, and held the SAT order is not a precedent.

Does acquiring control trigger an open offer even without crossing a share threshold?

Yes. Because the acquirer definition in Regulation 2(1)(a) expressly includes acquisition of control, and Regulation 4 independently mandates an open offer on acquisition of control "irrespective of acquisition or holding of shares or voting rights", a person who acquires control over a listed target must make an open offer even if no numerical threshold under Regulation 3 is crossed. This is why private-equity investors must scrutinise whether their governance rights cross the line from protection into control, the very issue in Subhkam.
