Synergy is not the sum of two businesses but the difference between the value of the combined company and the value of the same assets held separately. What matters most to an investor is who ends up with that difference: the premium over the target's standalone value passes to the seller's shareholders at the moment the deal closes — in cash or in shares, immediately and with certainty. The benefit of the combination, by contrast, has yet to be extracted, and it is the buyer who will have to extract it, at its own expense and at its own risk. That is why the question "is there synergy here" is almost always less important than the question "how much has already been paid for it".
What synergy is made of
Cost savings are the most verifiable part. Duplicated functions are eliminated, and procurement, logistics, IT infrastructure and leased premises are consolidated. This effect can be calculated line by line from the financial statements, it arrives relatively quickly, and it depends little on how the market behaves.
Revenue growth is the most frequently promised part and the most rarely confirmed. Cross-selling, access to the other party's distribution channel, a stronger bargaining position on price. All of this requires the seller's customer to agree to buy the buyer's product, and nobody gives that consent in advance.
The financial effect is a lower cost of funding thanks to a more resilient combined cash flow, a tax shield, and access to the debt market on better terms. It is tested by how the market prices the combined company's bonds relative to the OFZ curve; yields can be compared on the pages for the debt market and government securities.
Why the premium eats up the gain
The mechanism is simple and almost mechanical. A public target is rarely sold without competition: as soon as a deal is announced, a counterbid becomes possible, and the board of directors is obliged to consider the best price. To win, the buyer raises its offer — and raises it right up to the point where the expected synergy goes to the seller in full. The winner of an auction systematically pays more than it would have paid in the absence of rivals, because the winner is whoever valued the asset most optimistically of all.
Hence the typical market reaction to an announcement: the target's shares rise by almost the size of the premium, while the buyer's shares more often fall. This is not irrationality but a repricing of how the gain is distributed. The price moves on both sides of a deal are convenient to follow on the Russian equities page, set against the announcement date.
Where synergy settles in the financial statements
The difference between the price paid and the fair value of the target's net assets goes onto the balance sheet as goodwill. Goodwill is not amortised — it is tested for impairment every year. This is precisely why a goodwill write-down several years after a deal is the most honest public verdict on the synergy that was announced: the buyer acknowledges that it paid for an effect it did not obtain.
What deserves attention is not the press release with its integration plans but the reports that follow — segment revenue, the operating margin of the combined segment, the line for non-recurring integration costs. Filings are collected in the issuer reports section, and the dates of disclosures and corporate events in the events calendar.
Integration costs and dis-synergy
Synergy is almost never free. Severance payments, the unification of systems, rebranding, legal reorganisation, downtime during the transition period — these expenses arrive earlier than the savings do. There is also a reverse effect: the departure of key employees, the loss of customers unwilling to depend on an enlarged supplier, slower decision-making in a structure that has grown, and demands from the antitrust regulator to sell part of the assets. For a minority shareholder in the combined company there is a separate risk — a change in dividend policy: the debt raised to finance the deal is serviced from the same cash flow out of which distributions are paid. The history and the declared parameters of payouts are worth checking in the dividends section and the payout calendar.
How to read a synergy statement
A sensible sequence of checks runs as follows. Step 1 — separate the promised cost savings from the promised revenue growth and treat them differently. Step 2 — compare the announced annual effect with the premium paid: if the premium is comparable to the capitalised synergy, the buyer has handed the entire gain to the seller. Step 3 — check whether the presentation names the time needed to reach the full effect and the non-recurring costs of achieving it; their absence from the presentation is informative in itself. Step 4 — return to the financial statements several quarters later and see whether the promised effects have appeared in the segment figures.
What you will not find here
The platform publishes factual data — quotes, financial statements, corporate events, the news flow. There are no synergy forecasts in this database, nor can there be: such estimates come from the parties to the deal themselves and from analysts, and they are not disclosed fact. They can only be checked after the event, against the financial statements. Definitions of the terms that come up in descriptions of deals are collected in the glossary.
