LONDON, July 6, 2026, 12:01 BST
- Heath (Samuel) & Sons PLC (LON:HSM) was shown at 330p, up 10%, after one share traded at 11:17 London time.
- The 270p/330p sell-buy quote left a 60p spread, equal to 20% of the mid-price.
- The company says 79.0% of its 2.53 million shares are not in public hands.
- Latest half-year accounts showed £12.5 million of net assets, above the £8.36 million market value implied by the 330p quote.
Heath (Samuel) & Sons PLC (LON:HSM) rose 10% on Monday on screen, but the move came from one share worth £3.30, a thin-trading print that said more about liquidity than fresh demand for the Birmingham bathroom and hardware maker.
Google Finance showed Samuel Heath at 330p at 11:17:40 a.m. London time, up 30p on the day, with volume of one share, a market value of £8.36 million, and a 52-week range of 270p to 400p. Google AJ Bell’s tape showed the same one-share trade at 330p at 11:17:39, after a zero-quantity 270p print, with a sell price of 270p and a buy price of 330p.

| Day change | +10.0% |

The spread is the story. A 60p gap between the sell and buy quotes means the marked 10% move can be wiped out by the cost of crossing the spread. With 2,534,322 shares in issue, the 30p move from the prior 300p level added about £760,000 to the screen market value on a trade worth £3.30.
The stock was moving against a firmer small-cap tape, but the comparison is rough because the stock barely traded. The FTSE AIM All-Share was up 0.30% at 778.38 at 11:19 a.m., according to AJ Bell. AJ Bell London Stock Exchange regular trading hours run from 8:00 a.m. to 4:30 p.m. London time.
The thin market is structural. Samuel Heath says 79.0% of its shares are not in public hands, leaving about 532,000 shares in public hands on a simple calculation. At 330p, that public slice is worth about £1.76 million. The company also says its shares are traded only on AIM.
That matters because valuation screens can mislead on a stock this small. At 330p, Samuel Heath traded at about 0.67 times the £12.5 million of net assets reported at Sept. 30, 2025. Cash and cash equivalents were £2.62 million at that date, equal to roughly 31% of Monday’s quoted market value.

The last company RNS on Investegate was an April 1 director appointment, not a trading update. The previous full trading statement came with the half-year report on Nov. 26, when the company said first-half sales rose 1.9% to £7.69 million and operating profit edged up to £489,000. It also said order intake had been below budget since June 2025. Investegate
Profit before tax for the half year rose to £542,000 from £439,000, while basic earnings per share rose to 21.4p from 16.2p. The company proposed an unchanged interim dividend of 4.5p per share, paid on March 20.
The risk is in the order book, not the cash line. In the half-year statement, Samuel Heath said some customers were pausing projects while budgets were reassessed, and it pointed to caution in the London market after UK tax changes. The company also said U.S. tariffs had been passed on to customers.
Anthony Buttanshaw, the company’s non-executive chair, said in the latest full-year results that there was “evidence of the UK luxury market being affected” by tax changes. He also said the company had passed on the then-current 10% U.S. tariff level in full. Investegate
