Assessing Share Buybacks in UK-Listed Companies

A company announcing a share buyback is making an investment decision with shareholders’ money. The announcement may suggest confidence, but confidence alone does not establish whether the purchase is sensible. For investors in UK-listed companies, the useful questions concern the price paid, the demands on the business and what else the same money could achieve. A buyback deserves the same scrutiny as an acquisition or a new production facility.

These questions matter on both sides of the investment relationship. Lord Jonathan Kestenbaum, formerly chief operating officer of RIT Capital Partners, and Terry Smith, who founded Fundsmith in 2010, illustrate the institutional and fund-management settings in which decisions about shareholder capital are assessed. Their different professional backgrounds provide context for examining how boards deploy cash and how investors evaluate the result. Neither a familiar management team nor an established company removes the need to examine the economics of each purchase.

What the company is actually buying

When a company repurchases shares and cancels them, the remaining shareholders own a larger proportion of the business. However, the company also gives up cash. Whether continuing shareholders benefit depends partly on how the price compares with a reasonable estimate of the value surrendered by selling shareholders. Paying too much can weaken their position even when the reported number of shares falls.

Consider a simplified company with 100 million shares and an estimated equity value of £1 billion, including its cash. That implies £10 per share. If it spends £90 million buying and cancelling 10 million shares at £9 each, the remaining estimated equity value is £910 million across 90 million shares, or about £10.11 per share. At £11 each, purchasing the same number costs £110 million and leaves approximately £9.89 per remaining share. These examples ignore costs and changing business conditions, but demonstrate why price matters.

A higher earnings figure can mislead

Earnings per share can rise because profits improve, because the share count falls, or through a combination of both. Investors need to distinguish these effects. A business whose total earnings remain flat may report growth per share after a repurchase, without selling more products or improving its operating margin. That arithmetic can benefit continuing owners, but it does not establish that the underlying business has strengthened.

The calculation also needs to reflect the source of funding. Cash used for repurchases may previously have earned interest, while borrowing introduces an interest expense. Either can affect subsequent earnings. Published earnings per share generally uses a weighted average share count, so the timing of purchases matters too. Comparing operating profit, cash generation and the share count helps explain how much reported progress comes from trading and how much comes from financing decisions.

Compare the alternatives for the cash

A buyback should be considered alongside reinvestment, acquisitions, debt repayment and dividends. The strongest option depends on the opportunities available to that particular company. A business with ageing equipment or an underdeveloped distribution network may have productive uses for capital within its operations. Another may generate more cash than it can reinvest at an acceptable return. A smaller share count is useful only if the resources spent reducing it were well allocated.

Dividends and buybacks also distribute cash differently. A dividend pays eligible shareholders while leaving their ownership proportions unchanged. A buyback pays those who sell, while continuing investors retain a larger proportion of a company with fewer resources. Neither method creates value simply by transferring money. Investors should examine the remaining business, including its debt and capacity to fund future requirements, rather than adding the announced distribution to an unchanged estimate of company value.

Check whether the share count really falls

The amount spent on repurchases can look substantial while the overall share count changes little. Companies may issue shares through employee remuneration schemes or use equity to finance acquisitions. Buying shares to offset that issuance serves a different purpose from reducing the ownership base. Both can be legitimate, but investors need a clear account of the net effect before deciding what an announced programme means for their holding.

Annual reports and subsequent announcements can help reconcile opening and closing share numbers, cancellations, treasury shares and new issuance. Shares held in treasury may later be reissued, so they should not automatically be treated as permanently removed. Looking beyond the headline cash expenditure makes it easier to understand whether existing owners have gained a larger claim on future earnings or whether repurchases have mainly absorbed dilution elsewhere.

Judge execution over the whole programme

An announced maximum is not the same as completed expenditure. Investors should examine the shares actually acquired, the average price paid and any change in the company’s circumstances during execution. A programme that appeared reasonable when trading was strong may warrant reconsideration after a deterioration in demand. Equally, a falling share price does not automatically make repurchases attractive if the business has suffered a lasting loss of earning power.

Terry Smith’s fund-management background and Jonathan Kestenbaum’s former executive role at RIT Capital Partners represent different vantage points on the same allocation question: what does each pound committed leave for continuing owners? Answering it requires a valuation that recognises uncertainty, a realistic assessment of competing uses for cash and attention to the completed transactions. Over successive reporting periods, investors can then judge a buyback by the business and ownership interest that remain, rather than the size of the original announcement.
