Thanks, Tryn, and thank you, everyone, for joining us today. Through the second quarter, we continue to focus capital allocation on our three priorities; first, building and advancing our internal pipeline; second, completing investments in our platforms and facilities; and third, executing on select strategic partnerships. Starting with our internal pipeline. Both ABCL635 and ABCL575 are progressing well and we anticipate submitting Clinical Trial Applications, the Canadian equivalent of an IND in Q2 of 2025. Turning to our TCE efforts, we noted on the last call that our platform development is essentially complete and that we are moving leads from select programs into preclinical efficacy models. On the strength of data obtained in these studies, we may elect to bring one or more of these programs into our pipeline in 2025. Of the four programs currently being evaluated, three are in oncology, including PSMA, B7-H4, and an undisclosed target. PSMA is a well-validated target in prostate cancer, an area of high unmet medical need. To-date, clinical TCEs targeting PSMA have either shown high tumor cell killing with high toxicity related to cytokine release or low tumor killing with low toxicity. In our in vitro studies, we have shown that our PSMA TCE lead have comparable tumor cell killing to the most potent clinical benchmarks, while also having much lower cytokine release. We believe this profile has potential to achieve better safety, enabling higher dosing and better efficacy. B7-H4 is a target expressed on malignant cells in various solid tumors, including breast, ovarian and lung. Similar to our PSMA program, our B7-H4 TCE leads show comparable tumor killing and lower cytokine release as compared to the only relevant clinical benchmark. As with our PSMA program, we believe this profile has the potential to improve both safety and efficacy. For both PSMA and B7-H4, as well as for our third undisclosed target, there are currently no approved T cell engager therapies. Our fourth program is a TCE targeting CD19, and is being developed for autoimmunity. CD19 is a target expressed broadly and specifically on B-cells. The ablation of B-cells with CD19 directed CAR T has recently been shown to be highly effective in the treatment of lupus and is recognized to have broad potential in other autoimmune disorders where B-cells are implicated. As a modality, TCEs have clear commercial advantages over CAR T. Namely, cost, accessibility and convenience. Because of this, CD19 TCEs that were originally designed for oncology are now being repurposed and evaluated in the treatment of autoimmune conditions. Most notably, in studies with a small number of patients, Blincyto has shown early signs of efficacy in both rheumatoid arthritis and systemic sclerosis. The goal of our CD19 program is to achieve deep B-cell ablation comparable or approaching what is achieved with CAR T’s, along with convenient delivery and a best-in-class safety profile. We will provide updates on these four programs as they become available. In addition to being a source of potential internal programs, we continue to view our TCE platform as a basis for strategic partnerships. Speaking of partnerships, we’d like to congratulate Abdera for receiving IND clearance and FDA Fast Track designation for ABD-147, a radioisotope antibody conjugate for the treatment of patients with small cell lung cancer. As a reminder, AbCellera is a founding partner in Abdera and discovered the antibody from which ABD-147 is derived. AbCellera has a low single-digit royalty in Abdera’s programs, as well as a mid-single-digit equity ownership position in the company. We would also like to congratulate our partner Invetx on their upcoming acquisition by Dechra for up to $520 million in total consideration. Like with Abdera, AbCellera was a founding partner in Invetx, which is a companion animal health company that launched in 2018. Through the partnership, AbCellera has worked on multiple programs, three of which have reached clinical field studies. AbCellera has a low single-digit royalty in Invetx’s programs, as well as a mid-single-digit equity ownership position in the company. Finally, we recently announced an expansion of our partnership with Eli Lilly. This builds on a successful collaboration that started in March of 2020 and included eight antibody therapeutics discovery programs, as well as our COVID-19 pandemic response efforts. We are excited to continue our productive collaboration with Lilly. And we note that this follows expansions with other top-tier partners, including Regeneron and Gilead. And with that, I’ll hand it over to Andrew to discuss our financials. Andrew?
