FEH — Part I
Thank you, Bob.
Good afternoon everyone and thank you for joining us on today’s conference call.
As you know, earlier today we announced that we have entered into a definitive agreement to acquire Trubion Pharmaceuticals. This transaction includes upfront consideration of 96.8 million dollars of value and up to 38.7 million dollars of success-based milestones, resulting in a total consideration of up to 135.5 million dollars. Trubion is a Seattle-based biotechnology company focused on developing protein therapeutics targeting the key disease areas of oncology and autoimmunity, using its novel platform technologies.
We are very excited about this acquisition.
To begin, I would like to provide some context for this acquisition. Specifically, I will review our strategic vision, which will help you understand why Trubion is such a great fit for Emergent.
In pursuit of our mission to protect life, our strategic vision has always included the following two fundamental components:
    One: to strike a balance between vaccines and therapeutics; and
    Two: to build a portfolio of programs targeting multiple disease areas.
Since our inception, M&A has been instrumental to our growth and has consistently been a critical element of our strategy. In fact, including the Lansing, Michigan acquisition, we have completed four acquisitions in the last twelve years.
With respect to striking a balance between vaccines and therapeutics, as a biologics company, we recognize the significant value potential in pursuing the development of therapeutics. A main category of products in biologics are antibody-based therapeutics, which offer certain unique and highly attractive advantages, specifically:
    the potential to achieve human proof-of-concept earlier and in smaller clinical trials;
    the potential to share development costs over multiple indications; and,
    the potential to address multiple disease areas.



With respect to building a portfolio targeting multiple disease areas, we have so far built a pipeline of programs focused on infectious diseases only. However, we recently completed a comprehensive review to determine where we could leverage our infectious disease capabilities across other disease areas. In this review process, we took into account several criteria, which include:
    opportunities for biologics;
    short development timelines;
    clear approval paths; and
    degree of specialty focus.
Given these criteria and our core competencies in manufacturing and product development, the two disease areas that ranked highest after infectious disease were first oncology and then autoimmunity. In oncology, we are finding more and more that infectious disease and cancer are related. Certain cancers, as you know, are actually caused by viruses or bacteria.
I hope that by providing you with this brief strategic overview you now have sufficient insight into why we have decided to acquire Trubion. With that as a backdrop, let me discuss the business, scientific and financial perspectives related to this transaction.
From a business perspective, the acquisition of Trubion:
    Provides additional clinical-stage therapeutic candidates in the targeted disease areas of oncology and autoimmunity;
    Leverages our financial strength to support the continued development of the oncology lead candidate; and
    Leverages large pharma partnerships to provide sales and marketing infrastructure.
Let me take a moment to give you a brief description of Trubion’s product development pipeline. This includes:
    a clinical-stage, CD20 directed SMIP candidate, otherwise known as SBI-087, for the treatment of Rheumatoid Arthritis, which is in Phase 2, and Lupus, which is in Phase 1/2; these are being developed in partnership with Pfizer;
    a clinical-stage, CD37 targeted SMIP candidate, otherwise known as TRU-016, for the treatment of B-cell malignancies including CLL, which is in Phase 1/2, and NHL, which is about to enter Phase 1; these are being developed in partnership with Abbott; and
    promising preclinical platform-based candidates for the treatment of selected oncology and autoimmune diseases.
From a scientific perspective, the acquisition of Trubion:
    Provides access to two novel, protein therapeutic platforms—SMIP, and SCORPION;



    Gives us access to scientific expertise for developing innovative, and what we believe will be high-value therapeutic candidates; and
    Enables us to internally generate first-in-class candidates.
From a financial perspective, the acquisition of Trubion:
    Represents a minimal cash impact;
    Results in less than a 10 percent dilution; and
    Provides approximately 70 million dollars of NOLs.
Lastly, as stated in the press release, taking this transaction into account, we are reaffirming our 2010 guidance for revenues and net income.
Looking beyond 2010, we anticipate that we will remain profitable and, with proper R&D prioritization, we may be able to achieve earnings growth in the future.
That concludes my comments on the overall rationale for the deal. I will now turn it over to Jim who will provide greater detail on the scientific aspects of this acquisition.



Thank you, Fuad.
First as Fuad just mentioned:
The acquisition of TRBN with it’s two clinical stage therapeutic products, their portfolio of preclinical candidates and their recombinant protein therapeutic platforms — fit well with Emergent’s growth strategy. [AND] broaden[s] our therapeutic pipeline beyond infectious disease into autoimmunity AND oncology. Their proprietary — SMIP and SCORPION — platform technologies provide Emergent with a means to develop new mono-specific and multi-specific therapeutic candidates — either alone — OR — through partnerships.
I would now like to spend a few moments discussing in more detail the Trubion clinical candidates — Trubion’s proprietary protein therapeutic platforms — AND — why we are excited about acquiring these assets.
TRBN’s [is focused on] engineering and developing biologics-based, FIRST-IN-CLASS — “single-chain” recombinant protein therapeutics to serve unmet medical needs AND to provide SUPERIOR ALTERNATIVES — superior in terms of either greater efficacy and/or better safety profiles — TO MARKETED monoclonal antibody PRODUCTS.
TRBN’s portfolio consists of two clinical stage products; SBI-087 — an anti-CD20 molecule — which is in a phase 2 study as a treatment for rheumatoid arthritis or RA and TRU-016 — a first-in-class anti-CD37 protein therapeutic which is being evaluated in a phase 1 study as a treatment for certain B-cell malignancies (CLL and NHL).
First — SBI-087:
In collaboration with Pfizer, Trubion is developing SBI-087, a next generation CD20-directed product candidate. SBI-087 is an improved form of — AND — builds on Trubion and Pfizer’s clinical experience with TRU-015. SBI-087 is based on Trubion’s SMIP technology platform and has been genetically modified to be a humanized and potentially more potent derivative of TRU-015. ADDITIONALLY — SBI-087 has been FORMULATED for both intravenous infusion AND s.c. administration.



Patient dosing has commenced and recruitment is currently underway in a Phase 2 trial of SBI-087 for RA evaluating the safety and efficacy of subcutaneous administration of 200mg of SBI-087.
In addition, patient recruitment is ongoing in an additional Phase 1 trial of SBI-087 for RA in Japan. Finally, Pfizer is also conducting a Phase 1 clinical trial of SBI-087 in systemic lupus erythematosus, or SLE, in which patient dosing has commenced and recruitment is ongoing.
SBI-087 is licensed to Pfizer and [will be a future source for] future milestone payments and royalties.
The second — very exciting — clinical stage product is TRU-016 — a fully human — FIRST-IN-CLASS - anti-CD37 protein therapeutic. TRU-016 is the only anti-CD37 currently in clinical development. As you are aware — CD37 is a cell surface marker present at high levels on B-cells and lower levels on certain types of T cells and myeloid cells. Experiments suggest CD37 may play a role in B-cell regulation. In addition, CD37 is known to be over-expressed in patients with CLL. Importantly — CD37 is a clinically validated target for the treatment of B-cell malignancies.
Trubion is currently conducting an open label — Phase 1 clinical trial with TRU-016 in individuals with relapsed chronic lymphocytic leukemia or CLL. Based on the results obtained thus far Trubion has filed an amendment to this study to allow the treatment of BOTH naïve CLL patients — AND — subjects with relapsed NHL. Expansion of the clinical development program to other indications in oncology and autoimmune disorders is planned. TRU-016 is being developed as part of a 50:50 co-development partnership with Abbott.
Turning to TRBN’s proprietary SMIP and SCORPION technology platforms.
First, SMIPs. These “genetically engineered” Small Modular ImmunoPharmaceuticals” — or “SMIPs” - are recombinant protein therapeutic molecules that can be designed to overcome many of the limitations inherent to traditional monoclonal antibody products. SMIP therapeutics are expressed as single chain polypeptides and are comprised of a specific binding domain, a flexible hinge region allowing dimerization in vivo and an effector function domain designed to elicit predetermined therapeutic effects beneficial for specific diseases. SMIP proteins are mono-specific therapeutics — that is they are



drugs that recognize and bind only to a single target molecule — a soluble protein or cell surface protein — through the binding domain — and initiate a biological activity — through the effector domain. Thus SMIP therapeutics — while similar to classic monoclonal antibodies — possess unique structural design and effector characteristics compared to MAbs. SMIPs are also smaller than whole antibodies, which may allow for better in vivo penetration.
SMIPs — like traditional MAbs are produced using standard cell culture expression and manufacturing technologies; SMIPs can be formulated for both infusion and injectable delivery and have been shown to be stable under standard storage conditions.
Both TRU-016 and SBI-087 are SMIPs — as mentioned — TRU-016 targets CD37 and promotes both ADCC and apoptosis. SBI-087 recognizes CD20 and has been designed to elicit a FcDCC response.
Next, the SCORPION platform. This is a novel platform for the development of “bi-specific OR multi-specific” recombinant protein therapeutics. Like SMIPs, SCORPION proteins are expressed as “single-chain” polypeptides that spontaneously dimerize in cell culture — HOWEVER unlike SMIPs which recognize only one target — given their unique structural characteristics SCORPION molecules can recognize and bind multiple targets simultaneously — AGAIN either soluble molecules or cell surface-associated molecules. SCORPIONS — can also be designed to contain immunoglobulin effector function domains — like the SMIP therapeutics — BUT UNLIKE SMIPS - SCORPION therapeutics have the potential to also carry certain cell signaling moieties (such as cytokine ECDs). Thus, SCORPIONS can be engineered to bind multiple targets on the same or different targets on diverse cell types and modulate cell signaling by multiple pathways.
By utilizing different binding domains in various combinations — the scorpion platform allows the development of multiple first-in-class product candidates for autoimmune and inflammatory diseases (AIID), transplant, oncology, and other high unmet need areas
Using these platform technologies — TRBN’s scientists have identified and initiated development of several promising, potentially — high value preclinical candidates, which we plan to move into clinical studies in the near term.



While TRBN has thus far focused their SMIP and SCORPION technologies on the development of new products for autoimmunity and oncology — these platforms can also be leveraged for developing new candidates for infectious disease targets including biodefense.
And, finally, Trubion’s TRU-ADhanCe™, which is an elegant, proprietary, manufacturing technology that can be employed to increase the antibody-dependent cellular cytotoxicity, or “ADCC”, potency of product candidates by as much as 10-fold.
Trubion’s core protein therapeutic platforms — have the potential to generate multiple new — FIRST-IN-CLASS — therapeutic candidates and, as a result, additional value to our R&D pipeline.
Post-closing, in addition to our licensed product — Emergent — will have a substantial product pipeline, consisting of both vaccines and therapeutics with 5 products in clinical development — AND several very promising preclinical stage candidates — in the areas of both ID and oncology.
That concludes my prepared comments and I will now turn it over to Don who will provide greater detail on the deal terms.



Thank you, Jim.
As Fuad stated we are really excited about this acquisition. With the experience of the Trubion organization and the product candidates in process we believe that we have a combination that will result in significant financial returns for our shareholders.
As was stated earlier, we are acquiring Trubion for an upfront consideration of $96.8 million of value and up to $38.7 million of success-based milestones, resulting in a total consideration of up to $135.5 million.
Under the terms of the agreement, each share of Trubion Pharmaceuticals common stock will be converted into the right to receive an upfront payment of $1.365 per share in cash and 0.1641 shares of Emergent BioSolutions common stock. The upfront payment represents a value of $4.55 per share, or approximately $96.8 million, based on Trubion’s total common shares outstanding, the net value of dilutive stock options, and the trading average of Emergent’s common stock for the five days prior to the signing of the definitive agreement. In the aggregate, Emergent will issue approximately 3.35 million shares of its common stock as part of the upfront consideration, which after the closing of the merger will represent approximately 9.2 percent of Emergent’s total shares outstanding. Certain of these shares will be subject to lockup provisions.
Trubion Pharmaceuticals stockholders will also receive one Contingent Value Right (CVR) per share, which will entitle the holder to receive cash payments based upon achievement of five predefined Phase 2 and Phase 3 clinical study initiation milestones and one manufacturing-related milestone. The total potential aggregate value of the CVRs is $38.7 million over a 36-month period, following the closing of the merger.
Upon closing we anticipate that Trubion will have approximately $20 million in cash and $70 million of NOLs that we expect to be able to use over the next ten years. Additionally there are a number of milestone payments from the Abbott and Pfizer partnerships we expect to receive over the next five years.
The acquisition of Trubion is expected to close in the fourth quarter of 2010.
Trubion’s research facilities in Seattle, Washington will be maintained and the location will become a therapeutics-focused product development site for the combined company. We also expect to retain the majority of Trubion employees.
In terms of current year impact, we again re-affirm the 2010 guidance of $275 to $300 million and $40 to $50 million of net income. As you may realize the financial statements for 2010 will reflect the consolidation of EBS and Trubion only for the time between deal closing and the end of 2010.
Looking beyond 2010, we will focus carefully on pipeline optimization and identifying opportunities to realize financial synergies across the combined company — both R&D as well as G&A synergies. This entails evaluation of not only the Trubion programs but the EBS programs as well to ensure that we are targeting those candidates with the greatest probability of success from both a technical and financial perspective.
That concludes my prepared comments and I will now turn it back over to Fuad who will provide some concluding remarks.



FEH — Part II
Thank you, Don.
In conclusion, the acquisition of Trubion furthers our position as a leading, fully integrated biopharmaceutical company focused on the manufacture, development and commercialization of vaccines and antibody therapeutics.
We believe that the combination will allow the combined company to extract substantially more value from the Trubion pipeline and platform than would be possible had Trubion remained a stand-alone company.
Trubion’s clinical and preclinical stage programs as well as its leading edge science will expand our product development pipeline and will significantly broaden our antibody-based capabilities.
This acquisition brings us into oncology through a co-development arrangement with Abbott and a licensing arrangement with Pfizer.
Emergent’s stable vaccine franchise, substantial capital resources, and expertise in biologics combined with Trubion’s world-class protein therapeutic platform technologies and clinical-stage development programs should translate into significant value over the near and long term.
We are also excited about the potential for additional newsflow in the near term that the acquisition brings.
I look forward to sharing more information with you as the transaction moves to completion.
That concludes our prepared comments. I will now turn the call over to the operator, so that we can begin the question-and-answer portion of the call.
Operator, please proceed.
