  • Avacta has raised £9m gross (c £8.5m net) through an oversubscribed issue of c 12.8m new shares at 70p to institutional and existing investors, with one institutional cornerstone investor accounting for the majority of the funds. The shares were placed at the mid-market closing price on 4 June. New shares will be admitted to trading on 11 June 2026, increasing Avacta’s issued share capital to 471,330,508.
  • The terms of the convertible bond (CB) had been amended in August 2025 (September 2025 Lighthouse), with the repayment (including interest) of the January 2026 and April 2026 payments deferred to October 2027. The bond holders could accelerate the repayment of one or both deferred payments, in either cash or shares, from the earliest of: 30 June 2026, or the data readout of the faridoxorubicin Phase Ib study in triple negative breast cancer (TNBC). Additionally, from October 2026 bondholders could accelerate a quarterly repayment subject to a maximum of one acceleration per quarter.
  • Avacta can elect to pay an accelerated repayment in either cash or shares. The lowest electable reference prices for the January 2026 and April 2026 quarters would be c 48.75 pence and c 64.65 pence respectively. The issue of shares at 70p represents a saving of c £0.4m on these repayments, with c 2m fewer shares issued. There are also sufficient funds to pay an additional quarterly repayment. Management has opted to satisfy investment appetite using the new funds to minimise dilution due to the CB’s repayment discount.
  • The £9m raised is directed solely to fund three quarterly CB repayments, bringing the value of the convertible bonds down to c £11.5m, which represents c 3.6% of the market cap at last night’s close.

Trinity Delta view: Avacta is a pure play oncology company centred on the proprietary pre|CISION platform and PDC (peptide drug conjugate) assets, with management striving to reduce shareholder dilution as these advance towards near- and mid-term value inflection points. Faridoxorubicin, currently the lead programme, demonstrates the ability of pre|CISION to deliver a potent, toxic payload to the tumour microenvironment (TME) with minimal systemic effects; AVA6103, the lead Gen Two programme exploiting a sustained release mechanism for its exatecan payload, is in Phase I studies; with the lead Gen Three programme expected to complete IND-enabling studies. In our view, the key takeaway from this raise is that institutional investors (and management) are prepared to participate in a placing at market prices, suggesting solid confidence in the platform’s future potential and management’s ability to deliver it. Following the raise, we suspend valuation and forecasts. For context our last published valuation was £471m ($603m) or 103p/share.
