Oxford Instruments PLC (OXIG)


A bit of a primer on Oxford Instruments below, for anyone who may be interested.

I bought this quite recently because, although it seems quite dull, it may turn out to be a long-term compounder (alternatively, it may not! :grinning:)

1959 – husband and wife team Sir Martin and Lady Audrey Wood focussed on building powerful magnets in their garden shed, progressing to do their work within an abattoir and then a boat-house!

1983 – floated on the LSE. The purpose being to raise funds to develop powerful MRI magnets. One of the first University related spin-offs.

There is a more detailed history towards the bottom of the page on this link (with pictures!);

Drivers for Growth/Qualities of the company

  • Knowledge-based company with high levels of intellectual property. Difficult to replicate. The company has a good reputation, which is everything due to the accuracy required by clients.
  • Going for organic growth rather than buy and build, so maybe this reduces risk from pre-2015 when a buy and build strategy was followed.
  • The company sells ‘Picks and shovels’ products for the scientific community (ref Richard Beddard article). Possibly a good place to be?


  • Will management use the surplus cash which is now being generated wisely, or will it be used on purchasing companies at the wrong price ‘a la’ pre-2015?
  • Look again if Ian Berkshire (CEO) leaves
  • Is China at 22.6% of turnover a risk? Maybe not if they need OXIG’s products to progress their own science, unless the UK government bans exports to China?

Share price history

Price falls during 2013 to 2015 when the company de-rated from a pe of 25 to 13.2. This is explained in Richard Beddard’s article, the problem essentially being too much debt which was generated by acquisitions due to the then ‘buy and build’ strategy.


Currently trading at all time highs, which tends to be a point at which I like to purchase.

Currently pe=30.5. Is this over-rated?

  • Looking at dcf, with a fcf growth rate of 6.7% (the 5 yr average) and a discount rate of 10% the current share price is undervalued by 18%. (2887p vs 2445p)
  • Comparing to SDI and Judges they all seem pretty similar i.e. no one company stands-out. In fact, OXIG has the lowest fc PE of (only!) 28.6 per sharepad vs 30+.


Chairman (non-exec) – Neil Carson since Dec18 (ex Johnson-Matthey, ex chair TT Electronics, ex dep chair TI Fluid Systems).

Hi anon,

Many thanks for the write-up. Not a company I have looked at before.

Can’t fault this boardroom for lack of relevant industry skills. Plenty of physics and engineering degrees:

Chief exec Mr Barkshire studied Physics at York, which funnily enough my son will undertake there from next week.

Low board shareholdings have not stopped the business and share price from doing well:

OXIG is one of the few companies to operate with a defined-benefit pension surplus (£16m in the accounts).

Significant contributions to the scheme evade the P&L:

The accounting is legit, but these pension costs are genuine cash charges.

The notes indicate scheme assets of £340m have to fund annual benefits/admin charges of £9m. Interest from the assets was £8m last year, so the scheme’s assets (assuming modest investment gains over time) do seem sufficient to cover the present obligations:

Small-print says deficit recovery payments of £7.8m will be payable until 2026 and rise by 3% per annum:

So an extra £40m or so of cash out of the door. £40m is not significant if you add it to the £1.3 billion market cap for valuation purposes.

Revenue per employee is relatively high at c£200k and underpins the notion of attractive IP:

OXIG sharepad rev per employee

OXIG outperforms Judges and SDI on this measure:

JDG sharepad rev per employee
SDI sharepad rev per employee

I only screened by pension deficit to market cap.

Because the scheme is currently in surplus I didn’t look any further, but should have done!

It’s a good point, thank-you! (As are the points on relatively low level of director share-holdings and turnover per employee).
