CHAIRMAN'S UPDATE

I am pleased to present your Company's results for the 6 months to 30 September 2025.

Performance summary

The Company has maintained a positive total return over a 2-year and 5-year period across the qualifying portfolio. The NAV at the period end was 56.43 pence per share, which, after paying the 1.81 pence dividend in October 2025, represents a marginal decline of minus 1.36% for the NAV Total Return in the 6-month period since the March 2025 Financial year end.

The strongest positive movement within the qualifying portfolio was generated by Quai Administration Services, which sits within the technology segment. Quai provides platform technology and back-office administration services to the high-volume personal savings sector. The business has grown substantially in recent years and now oversees more than £2.5 billion of assets under administration, supports over 450,000 retail clients, and manages over 70,000 SIPPs. The uplift in carrying value over the past six months reflects both its sustained performance and a recently completed equity funding round.

Insurtech business Optalitix continued the strong momentum that made it the top-performing company in the 12 months to March 2025, achieving a further 20% increase in Contracted Annual Recurring Revenue. These results underscore the accelerating adoption of Optalitix's low-code SaaS platforms and reinforce its position as a strategic technology partner for leading specialty insurers and reinsurers. Optalitix's performance contributed an additional 0.23 pence of growth to the overall NAV per share.

Arecor, the drug discovery firm and one of only two AIM-listed companies within the portfolio, contributed a similar level of growth to the NAV per share. Improved investor sentiment led to a share price increase in the six months to September 2025, marking a positive step towards better alignment with the company's underlying fundamentals.

Given the broader economic and political environment and the recent period of instability, some valuation reductions across parts of the portfolio were unavoidable. These adjustments reflect the balanced and prudent valuation approach adopted by Calculus Capital as the Investment Manager. Home Team Content, a UK-based production company focused on elevating underrepresented voices, particularly filmmakers of colour and women , experienced a reduction in carrying value due to certain development delays. Nevertheless, the company remains committed to progressing its slate through strategic partnerships, distribution agreements, and new revenue opportunities.

IPV, a provider of proprietary software that enables efficient access, storage, modification, tagging, and transfer of video content, also saw a decline in its carrying value in the six months to September 2025. This reflects challenging industry conditions that have made securing new clients and driving revenue growth more difficult. Although growth has been slower than anticipated, the company has reached breakeven and expects to move into profitability.

Overall, the Company portfolio and sector balance continues to provide long term growth for shareholders. This has been recognised with one of the most successful fundraising periods for the Company across the 25/25 & 25/26 tax year share offer.

New and Follow on Investments

In August 2025 life sciences firm EnsiliTech was added to the qualifying portfolio. EnsiliTech's patented Ensilication technology preserves the integrity of vaccines, antibodies, and other biopharmaceuticals, eliminating the need for a cold chain, which allows medicines to be stored and transported at temperatures up to 50°C. The platform is validated across several 'proof-of-concept' projects with leading vaccine biomanufacturers. In August 2025, the Company raised £4.5m from existing and new investors to further commercialise the patented platform. The Company is advancing a promising development pipeline in collaboration with global partners in both animal and human health.

To further enhance the Company's life sciences sector, a follow-on investment was made in Laverock Therapeutics, with the company raising £20 million after extending its seed round in June 2025. Recent in vivo and in vitro data demonstrate successful, tunable, multiplex gene silencing and self-regulating expression, enhancing both persistence and safety. Laverock is now expanding beyond oncology, is actively engaging in partnership discussions for its CAR-T platform and is preparing for a Series A funding round in 2026.

During the 6 months to September 2025 an additional £2.5m of follow-on funding was deployed to support existing investee companies across the qualifying portfolio. Additional details on the breakdown of these investments can be seen below.

Company Exits

The six months to September 2025, along with the subsequent months, have also been a successful period for portfolio company exits. In June 2025 the Company exited Rota Geek ltd, a provider of AI driven workforce management and scheduling software. The company was sold to ELMO Group, a Australia-based HR technology provider. Rotageek was the 6th largest holding in the Calculus VCT portfolio as of the FYE March 2025 accounts, and represented the second  largest investment based on initial cost. The exit  provided a 1.3x multiple on cost for the Calculus VCT, returning just under £2m of proceeds to  the portfolio.

Following the half year-end, in November 2025, the Company exited Mo (Thanksbox Limited). Mo is an award winning employee engagement and recognition platform. The company was acquired by U.S. based UKG, a leading global AI platform unifying HR, pay, and workforce management. Calculus VCT first invested in 2020 this represented a 1.51x return on investment cost, delivering £1.53m in cash to the portfolio and further supporting the fund's annual target tax-free dividend yield for shareholders. Mo represents the second profitable exit achieved by the Calculus VCT in 2025. The exit valuation and final purchase price was 30% higher than Mo's carrying value in the March 2025 FYE accounts. This serves to further illustrate the conservative approach to valuations consistently employed by the Calculus Investment Management team. Specifically, Mo was valued through analysis of precedent M&A transactions, discounted cash flows, and comparable company metrics.

In the year to 30 September 2025, nine follow-on investments were made on behalf of the qualifying portfolio and three new investments were made:

New investment

Date of Investment Name of Investment Location Sector Amount of Investment
December 2024 Smartr365 Finance Limited United Kingdom Technology £742,500
March 2025 BookedIt Limited United Kingdom Technology £1,570,000
August 2025 Ensilicated Technologies Limited United Kingdom Healthcare £753,000

Follow-on Investments

Date of Investment Name of Investment Location Sector Amount of Investment
October 2024 Rain Dog Films Limited United Kingdom Entertainment 450,000.00
February 2025 Notify Technology Limited United Kingdom Technology £232,000
March 2025 Laverock Therapeutics Limited United Kingdom Healthcare £325,000
March 2025 IPV Limited United Kingdom Technology/Healthcare £990,000
June 2025 Laverock Therapeutics Limited United Kingdom Healthcare £107,000
June 2025 Riff Raff Entertainment Limited United Kingdom Entertainment £500,000.00
July 2025 Invizius Limited United Kingdom Healthcare £139,000
August 2025 Quai Administration Services Limited United Kingdom Technology £500,000
September 2025 Engaging Works Holding Limited United Kingdom Technology £538,000

We believe the portfolio is well positioned to continue to provide long term growth to shareholders and that our Investment Manager is similarly positioned to exploit these opportunities.

Buybacks

During the period, the Company bought back and cancelled 1,272,463 Ordinary shares. The Company continues to review opportunities to carry out share buybacks at a discount of no greater than 5% to NAV.

Dividends

As mentioned above, a dividend was paid on 2nd October 2025 of 1.81 pence per eligible Ordinary share. It is expected that the next dividend will be paid in March 2026 as announced below.

Board composition

The board consist of three Directors, two of which are independent from the Manager. Janine Nicholls stepped down from the Board of Directors with effect from 30 September 2025, following five years of dedicated service. Janine also served as Chair of the Audit Committee. The Company is pleased to announce that Hemant Mardia, currently a Non-Executive Director, has succeeded Janine as Chair of the Audit Committee, effective from 1 October 2025.  

Ordinary share issue

The offer for subscription for Ordinary Shares that opened on 14 October 2024 and closed on 2 October 2025 received aggregate subscriptions from the issue of Ordinary shares of £9.3 million. On 3 October 2025 a new prospectus was launched for a further offer for subscription for Ordinary Shares, with the shares to be issued in the 2025/26 and 2026/27 tax years.

Developments since the period end

In October 2025, the Company added Grateful Limited-a London- and Harrogate-based SaaS business that provides automated tip pooling and tronc solutions for the hospitality industry-to the qualifying portfolio. During the same month, the Company also completed a successful investment in drug discovery firm Trogenix Limited. The Calculus investment formed part of a £70 million Series A financing round intended to advance the clinical development of potential curative therapies for aggressive cancers.

These two new investments represent £1.7 million of capital deployed since 30 September. The strong level of deal flow and the addition of high-quality investee companies across diverse sectors is encouraging and further enhance the breadth and resilience of the well-diversified qualifying portfolio.

As mentioned above, in November 2025, the Company exited Mo (Thanksbox Limited) representing a 1.51x return, further supporting the fund's annual target tax-free dividend yield for shareholders.

In October 2025, a dividend of 1.81p per share was distributed to all eligible shareholders, achieving the Company's target dividend yield of 5%. During the same month, over £1 million was raised through a combination of an allotment and the Company's dividend reinvestment scheme. Since the period end, the Company has repurchased and cancelled an additional 707,389 shares at a price of 54.30p per share.

The new investments, profitable exits and buy backs in the subsequent months since the 30 September 2025 have significantly strengthened the company's liquidity position, delivered positive returns and enhanced shareholder value.

On the 26th November we heard what has been a long anticipated and purposely delayed Autumn budget. For months, warnings of potential tax hikes in various forms have dominated the headlines, and at times it appeared almost inevitable that Labour would break their manifesto pledge to leave income tax rates untouched. However, improved economic forecasts allowed the Chancellor to step back from this move.

The Chancellor has consistently expressed support for EIS and VCT legislation, recognising the role both schemes play in channelling capital into early-stage companies and promoting broader economic growth. This support was further reinforced by the Budget announcement to raise the annual and lifetime limits on the amount of EIS an VCT investment a single company can receive. However, a more counterintuitive change came in the form of the reduction of the income tax relief available through VCTs, reduced from 30% to 20%. This change comes despite the Chancellor's longstanding support for VCTs and their role in fostering growth and backing the UK's early-stage business ecosystem. The rationale given for this is to further balance the tax reliefs available across VCTs and EIS, with the change tax relief to be effective from 6 April 2026. Overall, it seems a counter-productive move within the Government's stated growth objective.

From April 2026, the basic and higher rates of dividend tax will each rise by two percentage points, increasing from 8.75% to 10.75% and from 33.75% to 35.75% respectively. Dividends paid by VCTs remain tax free. In an increasingly high-tax environment, VCTs remain stable and reliable source of tax relief. It is worth remembering that the sunset clause for VCTs was recently extended to April 2035, ensuring they remain a consistent and dependable option in a fiscal landscape that is constantly shifting and becoming progressively more punitive.

PRINCIPAL RISKS

The principal risks facing the Company remain the same as those detailed on pages 32 to 35 of the Annual Report and Accounts for the period ended 31 March 2025.

Brexit is still causing uncertainty however it remains our view that our portfolio companies are not experiencing material difficulties as a result of the political situation.

Regulatory and Compliance risks remain prevalent as the Company is listed on The London Stock Exchange and is required to comply with the listing rules of the Financial Conduct Authority, as well as with the Companies Act, Accounting Standards and various other legislations.

The main risks faced by the Company include, but are not limited to, loss of approval as a venture capital trust and other regulatory breaches, risks of making and realising qualifying investments, liquidity/marketability risk, changes in legislation/taxation, engagement of third-party advisers, market price risk and credit risk.

GOING CONCERN

There were no contingent assets or contingent liabilities in existence at 30 September 2025 (30 September 2024: £nil, 31 March 2025: £nil).

8. Fair Value Hierarchy

Investments held at fair value through profit or loss are valued in accordance with IPEV guidelines.

The valuation method used will be the most appropriate valuation methodology for an investment within its market, with regard to the financial health of the investment and the IPEV guidelines. As required by the Standard, an analysis of financial assets and liabilities, which identifies the risk of the Company's holding of such items is provided. The Standard requires an analysis of investments carried at fair value based on the reliability and significance of the information used to measure their fair value.

In order to provide further information on the valuation techniques used to measure assets carried at fair value, we have categorised the measurement basis into a "fair value hierarchy" as follows:

-    Quoted market prices in active markets - "Level 1"

Inputs to Level 1 fair values are quoted prices for identical asset in an active market. Quoted in an active market in this context means quoted prices are readily and regularly available and those prices represent actual and regularly occurring market transactions on an arm's length basis. The quoted price is usually the current bid price. The Company's investments in AIM quoted equities and money market funds are classified within this category.

-    Valued using models with significant observable market inputs - "Level 2"

Inputs to Level 2 fair values are inputs other than quoted prices included within Level 1 that are observable for the asset, either directly or indirectly.

-    Valued using models with significant unobservable market inputs - "Level 3"

Inputs to Level 3 fair values are unobservable inputs for the asset. Unobservable inputs may have been used to measure fair value to the extent that observable inputs are not available, thereby allowing for situations in which there is little, if any, market activity for the asset at the measurement date (or market information for the inputs to any valuation models). As such, unobservable inputs reflect the assumptions the Company considers that market participants would use in pricing the asset. The Company's unquoted equities and loan stock are classified within this category. Unquoted investments are valued in accordance with the IPEV guidelines.
