Sector briefing · Construction & building materials

Eight listed companies, one construction cycle

Sri Lanka's listed construction and building-materials ecosystem read from 25 company filings and 3,758 pages, reduced to 1,334 figures that each carry the document and page they came from. Margins, multiples and cash flows are recomputed from the statements rather than taken from any company's own presentation.

Covered: ACL, AEL, ALUM, CIND, RCL, SIRA, TKYO. These are separate listed issuers that meet at the same end market, not one industry classification — and two of them are the same group, which the comparison below handles explicitly rather than quietly.

01

Where each company sits in the value chain

These seven are not one trade. Six of them manufacture building materials and the seventh buys those materials to build with, so a duty that shields one is a cost to another. Where a company sits on the chain governs the direction of almost everything that follows.

02

What the headline figures conceal

A revenue or profit increase is only an operating improvement if it came from the business the company is understood to be in. Two cases here where it did not, each decomposed from the company's own disclosure.

03

The comparison

Scale and profitability do not travel together here. The second-largest company by revenue, Tokyo Cement at Rs 61.0bn, earns the thinnest net margin in the group at 4.2%; Sierra Cables earns the widest at 16.7% on a quarter of the revenue. The comparison below is on one basis and one date, because that is the only way the difference means anything.

Latest reported full year for each company. Scope is stated per row because it is not the same for all eight — two of these summary tables are not consolidated, and treating them as though they were is the most common way a sector screen goes wrong.

Margin structure, latest reported year
Gross, operating and net margin as a percentage of revenue. Bars share one scale. Blank where the company's summary table does not publish that line.

Derived from each company's own multi-year summary; margins recomputed from the revenue and profit rows rather than taken from any company's presentation.

04

How each multiple is built

Price, shares, profit, earnings per share, multiple

Why a public screen may show a different multiple

Corporate actions, and the adjustment applied

Subdivisions change the share count and therefore every per-share figure and every earnings multiple on this page. Each was nominated by a price screen, then confirmed against the company's own share-capital disclosure.

Two are graded as inferred: the filing does not narrate the action, but a figure printed in it can only be explained by that action.

The adjustment, shown on one year either side

A price is always quoted on the share base current that day, so every price before an ex-date is restated. Earnings per share is not: it sits on whatever base its own table used, and companies differ. Both columns are shown unadjusted and adjusted so the factor can be seen.

05

Method, in brief

Every figure on these pages carries the document and page it came from, and sixteen checks are run against the built data on every rebuild. What follows is how the reading was done and what it could not reach.

What was checked, and what the check returned

Sources — every document, with its page count and publication date
Share-base self-check — computed multiple vs the figure each company printed

A price divided by earnings on a different share count is wrong by exactly the subdivision ratio. Rebuilding each company's own convention and comparing against the multiple it printed catches that. The two that still disagree are shown, not smoothed.

What this briefing does not yet cover

The full research

The briefing above establishes the dataset and the reconciliations. The full edition extends it to the questions that need more than a screen.

  • Management promise tracking, with a status against later evidence
  • Infrastructure and contract exposure, separating awarded work from tender participation
  • Import-protection exposure by product line, with an adjustable stress test
  • A point-in-time earnings multiple explorer across 8.6 years of daily prices
  • Discounted cash flow with a full sensitivity grid, and what the market implies
  • Company-by-company profiles, risks and evidence gaps
