Bioventix: Bumper H1 Results Showcase ‘Modest’ 24% Growth As Renewed Troponin Optimism Helps Sustain 34x P/E

16 April 2019
By Maynard Paton

Results verdict on Bioventix (BVXP):

  • Very satisfactory 24% growth led by ongoing “modest” demand for the group’s vitamin D antibody.
  • Effect of terminated product licence may have obscured an underlying 28% revenue advance.  
  • Fledgling troponin product plus various pipeline developments offer intriguing long-term potential.  
  • First-class accounts continue to exhibit terrific margins, net cash and scope for further special dividends.
  • Valuation remains understandably rich with an underlying P/E of 34. I continue to hold.

  • Develops diagnostic antibodies for blood-test machines, direct competition for which is limited due to regulatory hurdles, scientific innovation, notable switching costs and revenue ‘lock in’ through ‘captive’ hospital end-customers.
  • Boasts founder/entrepreneurial/owner-friendly chief exec who has overseen an attractive growth record, retains an 8%/£17m shareholding and has declared three special dividends.
  • Employs asset-light royalty model that encompasses terrific margins, super returns on equity, decent cash flow and no debt.

Results summary

bvxp bioventix hy 2019 results results summary

Revenue, profit and dividend

  • Excluding back-dated royalties collected during the prior year, both revenue and operating profit advanced 24% to set new ‘underlying’ first-half records.
  • The performance continues BVXP’s style of under-promising and over-delivering. 
  • Management remarks within October’s full-year results had included (my bold): “Looking ahead… we keenly anticipate… modest growth from additional vitamin D antibody sales and royalties.
  • I am hopeful the current year could repeat 2016, 2017 and 2018, when management expectations of “modest” growth translated into 20%-plus underlying revenue/profit advances.
  • The first-half dividend was lifted 20%.

Adjustments for now-terminated product licence

  • These first-half numbers may have underplayed BVXP’s actual progress.
  • This product licence generated annualised revenue of £1m before its termination during August 2017.
  • Revenue from the now-terminated licence during H1 2018 (i.e. for July and August 2017) may have therefore been c£125k.
  • Adjusting for the now-terminated product licence and the back-dated royalties, revenue for this first half may have advanced from £3.4m to £4.4m — or 28%.
  • A grapevine source attended a post-results presentation, during which management claimed the group’s vitamin D antibody enjoyed H1 sales growth of 28% — matching my 28% estimate for ‘underlying’ sales growth.

Vitamin D

  • BVXP’s vitamin D antibody is the group’s best-seller — the product generated almost 50% of underlying revenue during 2018:

  • Within this results RNS, BVXP sounded a note of caution about vitamin D: “There is increasing evidence of a plateau in the downstream global vitamin D assay market.”
  • But BVXP did add: “Diazyme (San Diego, US) has made progress with their vitamin D assay which has the attractive feature of being run on general “chemistry” analysers.  Boditech (South Korea) is another Bioventix customer who uses the vitD3.5H10 antibody and has achieved significant success in the growing Asian vitamin D market with its vitamin D assay.”
  • According to my grapevine source, BVXP’s vitamin D antibody can be sold in greater volumes to owners of “general “chemistry” analysers”.
  • However, such volumes are offset by the lower price paid per antibody to BVXP.
  • My grapevine source says BVXP’s royalty on vitamin D remains at between 4% to 5% regardless of the customer. Other antibodies earn 2% royalties.
  • My grapevine source adds that BVXP’s management views a vitamin D ‘plateau’ to be sales growth reducing to between 5% and 10% per annum.

Other antibodies 

  • BVXP’s other products sold well: “Other revenue streams for the established antibodies to T3, NT-proBNP and progesterone also performed well during the period.
  • BVXP’s new troponin antibody — used to help detect potential heart attacks — continues to produce low sales. My grapevine source says £50k was recognised during the half.
  • However, management sounded a little more positive within this latest RNS (my bold): “We remain optimistic about our troponin revenues and the success of these high sensitivity troponin products around the world.
  • My grapevine source says BVXP’s house broker still believes troponin revenue could one day reach £3m.
  • BVXP’s development pipeline remains unchanged:

  • My grapevine source says initial testing of BVXP’s amyloid product — which is being developed in collaboration with Pre Diagnostics and aims to detect Alzheimer’s disease some five-to-ten years before onset — could be finalised during the next 18 months.
  • If successful, this amyloid product could require a further five years or so of regulatory trials before a commercial launch.

  • My grapevine source says management reckons the company is “making more adventurous choices” with its pipeline. In the past, BVXP had concentrated more on improving existing antibodies rather than developing novel products. 
  • These “adventurous choices” ought to support BVXP’s progress during the next decade:

  • BVXP’s accounts remain in extremely good shape.
  • A terrific 74% first-half operating margin underlines:
    • the lucrative nature of BVXP’s royalty income, and;
    • the competitive strength of the business.
  • Cash in the bank dropped by £1.5m to £5.5m during the six months. Earnings of £2.7m plus a favourable £0.5m working-capital movement were offset by the £4.7m payment of last year’s final and special dividends. 
  • Cash of £5.5m equates to 106p per share.
  • Cash of £5.5m is above the “approximately £5m”  that BVXP has said is “sufficient to facilitate operational and strategic agility with respect to possible corporate or technological opportunities that could arise in the foreseeable future.”
  • A bumper second-half could therefore lead to yet another special dividend (extra payouts were declared for 2016, 2017 and 2018).
  • The balance sheet carries no debt and no pension complications.


  • BVXP’s presentation included the 2019 forecasts from the group’s house broker:
bvxp bioventix hy 2019 results broker forecast 2019
  • A projected £5.9m profit after tax equates to earnings of 115p per share.
  • The house broker’s 2019 forecasts imply full-year revenue growing by 13% and pre-tax profit growing by 16%.
  • The 2019 forecasts also imply second-half revenue growing by 4% and pre-tax profit growing by 11%. 
  • Going on BVXP’s first-half performance and the implications for the second half, the house broker’s 2019 forecasts appear conservative.
  • The house broker’s forecasts for 2018 were conservative, too:
bvxp bioventix hy 2019 results broker forecast 2018
  • Excluding back-dated royalties, revenue and pre-tax profit for 2018 were in fact £8.0m (vs. £7.2m forecast) and £6.1m (vs. £5.5m forecast) respectively.
  • BVXP’s trailing twelve-month operating profit is £6.7m, which taxed at the 15% rate applied within these results gives earning of £5.7m or 110p per share.
  • Subtract the 106p per share cash position from the 3,850p share price gives an enterprise value of 3,744p per share.
  • Dividing that 3,744p by the 110p per share earnings figure gives an underlying trailing P/E of 34.
  • The rating is undeniably rich at twice the market average. 
  • However, BVXP’s underlying earnings have increased by at least £3m during the last five years, while shareholder equity has advanced by almost £7m.
  • BVXP’s five-year incremental return on equity is therefore £3m/£7m or c40%, which is at least twice as high as that of the average quoted company — and perhaps explains why BVXP’s P/E rating is twice as high, too.  
  • The trailing 66p per share ordinary dividend supports a modest 1.7% yield.

  1. Good report Maynard. Nothing material to add that I can think of. If anything I’d argue that your ROE sums understate things really, as pretty much all of BVXP’s cash is surplus cash that is not needed in the business. It’s quite a big number too, £5.5m out of £9m of equity.

    Not sure I’ve ever come across a business with better economics than this – it’s really up there with the best of the best.

    • Hello Phil,

      Thanks for the comment and apologies for the tardy reply.

      BVXP has said it likes to retain about £5m to “facilitate operational and strategic agility with respect to possible corporate or technological opportunities that could arise in the foreseeable future.

      So perhaps the £5m is not surplus, although as you imply the cash seems to sit there and do nothing while more cash rolls in. Either way the ratios are superb.
