Cap Table vs Share Register vs Ownership Chart

Three records, one ownership fact

Cap table vs share register is a question about which record answers which question. A share register is a company’s own entry-by-entry record of who holds its shares and since when — the same record kept as a stock ledger in the United States. A cap table is a financing analysis built from those entries. An ownership chart is the picture of which entity holds which, through every layer of a group.

What a company must keep, and in what form, differs by where it is incorporated — confirm the specifics for your entities with counsel.

What a share register records

A share register — also called a shareholder register or a register of members — is the company’s own record of who holds its shares in the entity that issued them. It carries the holder’s name, the class of shares, the number held, and the date each holding was entered, along with the certificate number, the holder’s address, and the date a holding was transferred out. The company maintains it, entry by entry, as an accumulating record rather than a snapshot rebuilt periodically.

That structure is what a share register includes that a cap table does not: an entry date attached to each holder’s line, rather than a percentage recalculated at the moment of a financing round. A lender confirming collateral, a buyer confirming a seller’s ownership, or a court settling a dispute over who held a security on a given date turns to the register first. It is legal ownership evidence, not a deal’s economics.

What a cap table models

A cap table models the same ownership as a financing analysis: issued shares, option pools, warrants, and convertible instruments such as notes or SAFEs. Fully diluted, it’s arranged so a round’s effect on every holder’s percentage can be read off in one view. It answers what happens to each holder’s stake if a financing closes — a different question than the register answers.

That forward-looking shape is the feature, not a shortcoming. Is a cap table a legal record of share ownership?

It is an analysis derived from the underlying ownership entries; the entries themselves live on the register. The cap table models what those entries mean for a transaction; it doesn’t stand in for the entries as the record of the transaction.

Convertible instruments sit naturally inside a cap table because they change a holder’s fully diluted percentage before they ever convert to shares. That’s one more reason a cap table stays current only as often as someone updates it from the entries behind it.

What an ownership chart shows

An ownership chart shows the relationships instead of the holdings. It shows which entity holds which, at what percentage, through how many layers between a parent and an operating company — a structural question neither the register nor the cap table is shaped to answer, because both live inside a single entity.

Ownership chart vs cap table comes down to shape: a cap table is one entity deep and many holders wide, listing every party that holds a piece of one company. A chart is many entities deep, tracing one ownership line down through a whole group.

What an ownership chart shows that a cap table cannot is the path itself — the sequence of holding companies between the top of a group and the subsidiary running the business. No single cap table contains that path, because no cap table is built to span more than one entity.

A chart is a picture drawn from the registers underneath it, current only as of the last time someone redrew it.

Which record answers which question

The difference between a cap table and a shareholder register shows up fastest as a list of questions: pick the record by the question in front of you, not by habit.

Read that way, most of the questions counsel is asked resolve to the register or the chart, and the cap table answers a question counsel is rarely the one asking. Which record proves who owns a subsidiary? The register: one entry naming the parent. That’s also where a corporate group changes the picture, because a group multiplies the number of registers in play and often skips the cap table almost entirely.

What a corporate group changes

The three-record question above was written for one company with outside investors, answering who owns a stake in it. A corporate group changes the answer, because most of a group’s entities have exactly one holder, and that changes which record does any work at all.

A wholly owned subsidiary

How ownership of a wholly owned subsidiary is recorded comes down to one line: a single register entry naming the parent as the holder, plus the transaction — usually a formation or a contribution — that created it. Does a subsidiary need a cap table? Rarely: a cap table for a single-holder entity just restates that one line as a hundred-percent stake, with no round or option pool to model.

The interesting case is the near-wholly-owned subsidiary — a management team’s rollover stake, a local nominee holding a qualifying share, a joint-venture partner at a minority percentage. That single minority line is where the register, the chart, and any cap table the entity needs start to diverge. It’s the line that decides who has to consent to a transaction and whose stake shows up in a beneficial-ownership review. Record it as ownership across a corporate family, not a one-off note in the subsidiary’s file, so the parent’s own stake is traceable from the same place as everyone else’s.

Thresholds and filing consequences for a minority holding differ by jurisdiction; confirm what applies to your entities before treating any percentage as a bright line.

Who keeps each record

Who keeps the share register and who keeps the cap table is rarely the same person once a group has more than a couple of entities:

• The register for each subsidiary sits with that entity’s company secretary or counsel
• The cap table sits with finance or whoever runs the equity platform at the top company
• The chart is redrawn by whichever person was asked for it last, which is why it is the record most often out of date

That’s three records, three owners, and three update cadences, with no single event that triggers all three at once — and that gap, not any one person’s mistake, is the actual source of group-level ownership error. Counsel at a fund or a scaling group tends to live in the register and the chart, not the cap table — what a fund’s counsel is asked for rarely turns out to be a financing question.

One parent, one subsidiary

Sample Meridian Holdings, Inc. owns most of its operating subsidiary, Sample Meridian Operations, Inc., alongside a manager who rolled part of their stake into the deal. Every figure below — names, dates, share counts, percentages — is invented for illustration. This page is not legal advice, and it states nothing about what any law requires.

Sample Meridian Operations has 1,000 common shares issued. Sample Meridian Holdings holds 900 of them, a 90% stake. Sample Manager A holds the other 100, a 10% rollover stake.

The same facts, three ways

The register view for Sample Meridian Operations:

Two rows, each carrying its own entry date. This is the register answering “who holds, since when” — nothing more.

The cap table view expresses the same two holders differently:

• Sample Meridian Holdings, Inc. — 90% fully diluted
• Sample Manager A — 10% fully diluted
• An option reserve at Sample Meridian Holdings’ own parent level — a line the subsidiary’s register has no room for, because it changes Sample Meridian Holdings’ percentages without touching Sample Meridian Operations’ register at all

The chart view draws it as one box above another: Sample Meridian Holdings above Sample Meridian Operations, the 90% marked on the edge connecting them, and Sample Manager A’s box entering from the side at 10%. What the chart makes obvious that neither table does is where that 10% sits — at the operating company, not the parent — a different economic position than a reader skimming a consolidated cap table might assume.

Where the three disagree

On 2026-04-02, Sample Manager A transfers 40 shares to a new hire, Sample Manager B. Watch the divergence in order, because this is the passage the example exists to show:

1. The transfer is agreed and signed. All three records are still wrong — nothing has been entered anywhere yet.
2. The entry is made in the register, dated 2026-04-02. The register is now right. The cap table still shows Sample Manager A at 10%; the chart still shows one minority holder.
3. At quarter end, finance rebuilds the cap table from the register. Two of the three records now agree.
4. The chart is redrawn the next time someone asks for it, which may be months later — the last of the three to catch up.

Which record is the source of truth for who owns shares? The register entry and its date, because it’s the only one of the three with a date on the fact itself, not on a later recalculation of it.

The cap table is an analysis of those entries, and the chart is a picture of them — both correct, both derivative, both current only as of whenever someone last rebuilt them. What was missing at every step wasn’t diligence; it was a trigger tied to the entry date, which is where the next section starts.

Keeping the three in agreement

Why the numbers diverge

Why the cap table and the share register disagree comes down to three causes, all record-keeping rather than legal ones:

• The three records update on different triggers — an entry, a financing round, a request for the chart
• A transfer that’s signed isn’t yet a transfer that’s entered
• A parent-level instrument can move the cap table’s percentages without ever touching a subsidiary’s register

What your entities must keep, and how quickly, differs by jurisdiction — confirm it with counsel.

The register entry date

The reconciliation discipline is simple to state and easy to skip: give every ownership change one dated entry, and rebuild the cap table and the chart from those entries rather than editing either one in place.

An Ownership Stake carries the owner, the holding, ownership and voting percent recorded separately, and the units or shares held. An Equity Transaction is a single change of equity on a given date, and every stake reconciles against the transactions that created or changed it. Every transaction carries a register entry date, so the timing of an ownership change is never in question.

A stake’s status runs Acquired through Sold, Transferred, or Disposed of. Share certificates and subscription agreements are stored on the stake they evidence, and keeping dated extracts from the register on file means who held what on a prior date is answerable without reconstructing it from memory.

What each system holds

Lextree holds the ownership stake and the dated transaction behind it for every entity in the group; dilution modeling, option-pool math, and 409A valuation stay in the equity platform built to do them. That’s where the register sits among corporate records — one register among many — and it’s why tracking ownership across many subsidiaries starts with the register rather than a spreadsheet rebuilt every quarter.

The three records were never competing for the same job. The register, the cap table, and the chart each answer a different question, and the only one that has to be current the moment something happens is the one with the date on the fact itself.
