PART I

ITEM 1: BUSINESS

Overview

We are a specialty biopharmaceutical company focused on the development and commercialization of innovative treatments for diabetes that may be safer, more effective and more convenient for patients. We develop our product candidates by applying our proprietary formulation technologies to existing drugs in order to improve their therapeutic profiles. Our proprietary insulin formulations are designed to be more rapid-acting than the formulations currently available to Type 1 and Type 2 diabetes patients. We refer to these as "ultra-rapid-acting" formulations. Our glucagon formulations and presentations are designed to be stable at room temperature and are intended for use by caregivers with no medical training as a rescue treatment for diabetes patients experiencing severe hypoglycemia, or very low concentrations of blood glucose.

Our most advanced ultra-rapid-acting insulin formulation, BIOD-123, combines recombinant human insulin, or RHI, with our proprietary combination of excipients to increase the rate of absorption following injection when compared to other commercially available insulin formulations, including "rapid-acting" mealtime insulin analogs such as Humalog®, marketed by Eli Lilly, Novolog®, marketed by Novo Nordisk and Apidra®, marketed by Sanofi-Aventis. We are also using our proprietary excipients to develop ultra-rapid-acting insulin analog-based formulations using either insulin lispro, the active pharmaceutical ingredient in Humalog®, or insulin aspart, the active pharmaceutical ingredient in NovoLog®.

An earlier RHI-based formulation known as Linjeta™ (and previously referred to as VIAject®) was the subject of a New Drug Application, or NDA, that we submitted to the FDA in December 2009. In October 2010, the FDA issued a complete response letter stating that the NDA for Linjeta™ could not be approved in its submitted form and that we should conduct two new Phase 3 clinical trials using our preferred commercial formulation of Linjeta™ prior to re-submitting the NDA. Based upon the complete response letter and subsequent feedback that the FDA provided, we decided to develop newer RHI-based formulations with the goal of identifying a formulation with a pharmacokinetic and pharmacodynamic profile similar to Linjeta™, but with improved injection site toleration characteristics. From January 2011 to April 2012, we studied several such newer formulations, including BIOD-123, in Phase 1 clinical trials. In these trials, we used Humalog® as the comparator drug rather than the comparator drug we used in our Phase 3 Linjeta™ clinical trials. In our Phase 3 clinical trials, the comparator drug was Humulin® R, an RHI-based insulin formulation marketed by Eli Lilly that is less rapid-acting than the insulin analog Humalog®.

BIOD-123 achieved our target pharmacokinetic, pharmacodynamic and injection site toleration profiles for a candidate RHI-based formulation in a Phase 1 clinical trial completed in April 2012, and in the third calendar quarter of 2012 we began enrolling patients in a Phase 2 clinical trial of BIOD-123. The Phase 2 clinical trial of BIOD-123 was a randomized, open label, parallel group study conducted at 32 investigative centers in the United States. In the trial, 132 patients with Type 1 diabetes were randomized to receive either BIOD-123 or Humalog® to use as their mealtime insulin during an 18-week treatment period. Both arms of the study used insulin glargine, sold as Lantus®, as the basal insulin. The clinical trial was designed to evaluate the mean change in patients' glycosylated hemoglobin, or HbA1c, levels from baseline as the primary endpoint, and secondary endpoints included postprandial glucose excursions, glycemic variability, hypoglycemic event rates and weight changes.

The Phase 2 clinical trial of BIOD-123 completed patient dosing in the second calendar quarter of 2013, and in September 2013 we announced preliminary results from the trial. BIOD-123 achieved the primary endpoint of noninferiority for HbA1c relative to Humalog®. The mean HbA1c change from baseline in the BIOD-123 group was -0.08 ± 0.064% and -0.25± 0.063% in the Humalog® group. The 95% confidence interval (-0.01, 0.35) of the between group differences in change from baseline HbA1c did not exceed the FDA-designated threshold of 0.40%, thereby establishing non-inferiority. We expect to provide an update on our further development plans for BIOD-123 after completing our analysis of the data from the Phase 2 clinical trial and following discussions with FDA on clinical trial design, safety and chemistry, manufacturing and controls relating to potential future studies.

In addition to BIOD-123, we have other RHI-based formulations in earlier stages of development. In particular, we are developing ultra-rapid-acting formulations of concentrated insulin that are characterized by a

3

rapid onset of action and a prolonged duration of action. We believe these formulations could address an unmet medical need for an insulin with an initial rate of absorption superior to that of existing concentrated insulins and prandial/basal pre-mixed insulins. In November 2013, we announced that we had initiated a Phase 1 clinical trial with BIOD-531, our lead candidate for an ultra-rapid-acting concentrated insulin formulation. BIOD-531 contains 400 units of RHI per milliliter (instead of the standard 100 units per milliliter), and is formulated with EDTA, citrate and magnesium sulfate. In preclinical studies in diabetic swine, BIOD-531 demonstrated a more rapid rate of absorption and onset of action, along with a similar duration of action, when compared to Humulin® R U-500, a presentation containing 500 units of RHI per millimeter. In other preclinical studies, BIOD-531 also demonstrated a more rapid rate of absorption and onset of action when compared to Humalog® pre-mixed prandial/basal formulations. In the Phase 1 clinical trial of BIOD-531, we will evaluate and compare the onset of action of BIOD-531 to Humulin® R U-500 and to Humalog® prandial/basal pre-mixed insulin. We anticipate reporting top line data from the clinical trial in the first calendar quarter of 2014.

We also continue to develop ultra-rapid-acting insulin analog-based formulations. In January 2013, we announced top-line results from our Phase 1 clinical trial of two insulin analog-based formulations, BIOD-238 and BIOD-250. These formulations, which were manufactured using commercial preparations of Humalog®, generally use the same or similar excipients as BIOD-123 and were intended to be optimized for rapid absorption and injection site toleration. The trial, which was conducted in Australia, was designed to compare the pharmacokinetic and injection site toleration profiles of BIOD-238 and BIOD-250 relative to Humalog®. In the trial, both formulations met our target pharmacokinetic profile for an ultra-rapid-acting insulin analog-based formulation, and BIOD-250 met our target injection site toleration profile. We do not expect to study these formulations in additional clinical trials because they were formulated by adding our proprietary excipients to the marketed formulation of Humalog® and because they do not demonstrate stability characteristics consistent with our target product profile. Accordingly, we are continuing our insulin analog-based formulation work to develop formulations using insulin lispro as the active pharmaceutical ingredient, rather than a marketed presentation of Humalog®.

In addition to our ultra-rapid-acting insulin formulation program, we are developing room temperature stable glucagon presentations for use as a rescue treatment for diabetes patients experiencing severe hypoglycemia. In June 2013, we announced plans to develop a novel glucagon rescue product to treat severe hypoglycemia using a proprietary device from Unilife Corporation. The device, which is being customized for use in emergency situations by patient caregivers with no medical training, is a dual-chamber design that reconstitutes lyophilized glucagon with a liquid diluent immediately prior to injection, and it features automatic needle retraction on full dose delivery. We expect to submit an Investigational New Drug application to the FDA for our dual-chamber glucagon rescue product during the next nine months and anticipate conducting a pivotal clinical trial in the second half of 2014. We are also conducting preclinical testing to develop liquid formulations of glucagon for hypoglycemic rescue and other indications.

Diabetes and Insulin Therapy Overview

Glucose is a simple sugar used by all the cells of the body to produce energy and support life. Humans need a minimum level of glucose in their blood at all times to stay alive. The primary manner in which the body produces blood glucose is through the digestion of food. When a person is not getting this glucose from food digestion, glucose is produced from stores and released by the liver. The body's glucose levels are regulated by insulin. Insulin is a peptide hormone that is naturally secreted by the pancreas. Insulin helps glucose enter the body's cells to provide a vital source of energy.

When a healthy individual begins a meal, the pancreas releases a natural spike of insulin called the first-phase insulin release. In addition to providing sufficient insulin to process the glucose coming into the blood from digestion of the meal, the first-phase insulin release acts as a signal to the liver to stop making glucose while digestion of the meal is taking place. Because the liver is not producing glucose and there is sufficient additional insulin to process the glucose from digestion, the blood glucose levels of healthy individuals remain relatively constant and their blood glucose levels do not become too high.

Diabetes is a disease characterized by abnormally high levels of blood glucose and inadequate levels of, or response to, insulin. There are two major types of diabetes — Type 1 and Type 2. In Type 1 diabetes, the

4

body produces no insulin. In the early stages of Type 2 diabetes, although the pancreas does produce insulin, the body loses its early phase insulin response to a meal. In addition, the body's cells do not respond as well as they should to a normal amount of insulin, a condition known as insulin resistance. According to the Centers for Disease Control and Prevention, or CDC, Type 2 diabetes is the more prevalent form of the disease, affecting approximately 90% to 95% of all people diagnosed with diabetes.

Even before any other symptoms are present, one of the first effects of Type 2 diabetes is the loss of the meal-induced first-phase insulin release. In the absence of the first-phase insulin release, the liver will not receive its signal to stop making glucose. As a result, the liver will continue to produce glucose at a time when the body begins to absorb new glucose through the digestion of the meal, and the blood glucose level of patients with diabetes rises too high after eating, a condition known as hyperglycemia. Hyperglycemia causes glucose to attach unnaturally to certain proteins in the blood, interfering with these proteins' ability to perform their normal function of maintaining the integrity of the small blood vessels. With hyperglycemia occurring after each meal, the tiny blood vessels eventually break down and leak. The long-term adverse effects of hyperglycemia include blindness, loss of kidney function, nerve damage and loss of sensation and poor circulation in the periphery, potentially requiring amputation of the extremities.

Patients with diabetes, particularly those with Type 1 diabetes, are also at risk for abnormally low levels of blood glucose, known as hypoglycemia, that can result from excessive insulin between meals. Hypoglycemia can result in loss of mental acuity, confusion, increased heart rate, hunger, sweating and faintness. At very low glucose levels, hypoglycemia can result in loss of consciousness, coma and even death. According to the American Diabetes Association, or ADA, patients with Type 1 diabetes have a serious hypoglycemic event approximately once per year, many of which require hospital emergency room visits.

Insulin Therapy and Its Limitations

Because patients with Type 1 diabetes produce no insulin, the primary treatment for Type 1 diabetes is daily intensive insulin therapy. The treatment of Type 2 diabetes typically starts with management of diet and exercise. Although helpful in the short-term, treatment through diet and exercise alone is not an effective long-term solution for the vast majority of patients with Type 2 diabetes. When diet and exercise are no longer sufficient, treatment commences with various non-insulin medications. These non-insulin medications may be limited in their ability to manage the disease effectively and can have significant side effects. Because of the limitations of non-insulin treatments, many patients with Type 2 diabetes deteriorate over time and eventually require insulin therapy to support their metabolism.

Insulin therapy has been used for more than 80 years to treat diabetes. This therapy usually involves administering several injections of insulin each day. These injections consist of administering a long-acting basal injection one or two times per day and an injection of a rapid-acting insulin at mealtime. Although this treatment regimen is accepted as effective, it has limitations. First, patients generally dislike injecting themselves with insulin due to the inconvenience and pain of needles. As a result, patients tend not to comply adequately with the prescribed treatment regimens and are often inadequately medicated.

More importantly, even when properly administered, insulin injections do not replicate the natural time-action profile of insulin. In particular, the natural spike of the first-phase insulin release in a person without diabetes results in blood insulin levels rising within several minutes of the entry into the blood of glucose from a meal. By contrast, injected insulin enters the blood slowly, with peak insulin levels occurring within 80 to 100 minutes following the injection of recombinant human insulin.

A potential solution is the injection of insulin directly into the vein of diabetic patients immediately before eating a meal. In studies of intravenous injections of insulin, patients exhibited better control of their blood glucose for 3 to 6 hours following the meal. However, for a variety of medical reasons, intravenous injection of insulin before each meal is not a practical therapy.

One of the key improvements in insulin treatments was the introduction in the 1990s and 2000s of rapid-acting insulin analogs, such as Humalog^��, NovoLog^® and Apidra^®. However, even with the rapid-acting insulin analogs, peak insulin levels typically occur within 50 to 70 minutes following the injection. Because the rapid-acting insulin analogs do not adequately mimic the first-phase insulin release, diabetic patients using insulin therapy continue to have inadequate levels of insulin present at the initiation of a meal and too much

5

insulin present between meals. This lag in insulin delivery can result in hyperglycemia early after meal onset. Furthermore, the excessive insulin between meals may result in hypoglycemia.

Additional complications of insulin therapy can arise if a patient's response to insulin diminishes with the progression of the disease. Some patients with Type 2 diabetes have severe insulin resistance, resulting in the need to take more than 200 units of insulin per day to control blood glucose elevations. In order to reduce the volume of insulin needed for each injection, many of these patients use Humulin® R U-500, a presentation of Humulin® R containing 500 units of RHI per milliliter (instead of the standard 100 units per milliliter). Humulin® R U-500 has a long duration of action, but its onset of action is very slow and therefore is not ideally suited to cover the elevation of glucose levels associated with meals. Humulin® R U-500 is currently the only concentrated insulin on the U.S. market. Many other patients with Type 2 diabetes and lesser degrees of insulin resistance use mixes of prandial and basal insulins, which offer a combination of shorter- and longer-acting insulins in the convenience of one injection. However, the mealtime component of these "pre-mixed" insulin formulations is typically absorbed more slowly than what is required to optimally cover the elevation of glucose levels associated with meals. Examples of these "pre-mixed" insulins include Humalog^® Mix 75/25, Humalog® Mix 50/50 and NovoLog^® Mix 70/30.

Glucagon Rescue Treatment and Its Limitations

Hypoglycemia is often treated by the oral administration of carbohydrates, such as orange juice or glucose tablets. However, in the case of severe hypoglycemia, the patient often experiences neurologic compromise, such as loss of consciousness or seizure. In these emergency cases, it is typically unsafe for carbohydrates to be administered by mouth and the patient requires the assistance of another person. In such cases, an injection of glucagon can be administered to help quickly raise the patient's blood glucose concentration.

Glucagon, like insulin, is a hormone secreted by the pancreas. Glucagon opposes the action of insulin by promoting the breakdown of glycogen into glucose in the liver, thereby raising the levels of blood glucose. Although glucagon injections are useful in treating severe hypoglycemia, glucagon is inherently unstable in a liquid solution. Therefore, injectable glucagon for the treatment of severe hypoglycemia is currently available only as a rescue kit consisting of a vial containing a dry powder of glucagon and a syringe containing a liquid solution. To administer glucagon with this kit, the liquid solution must first be injected into the vial with the dry powder, the contents need to be adequately mixed and then the solution is drawn back into the syringe. After the glucagon powder is dissolved, it is injected into the patient. In order to properly administer the glucagon, a caregiver must follow this multi-step process in a situation typically made challenging by the patient's condition.

Our Development of Ultra-Rapid-Acting Insulin Formulations

Our proprietary ultra-rapid-acting insulin formulations are designed to be absorbed into the blood faster than the currently marketed rapid-acting insulin analogs. One of the key features of our formulation technology is that it allows the RHI or insulin analog to disassociate, or separate, from the six molecule, or hexameric, form to the single molecule, or monomeric, form and inhibits re-association to the hexameric form. We believe that by favoring the monomeric form, our formulations may allow for more rapid delivery of insulin into the blood because insulin in the form of a single molecule is absorbed more efficiently into the bloodstream. Based upon our preclinical and clinical data, we believe our RHI- and insulin analog-based formulations may produce a profile of insulin levels in the blood that is preferable to the profile typically observed when using the currently marketed "rapid-acting" insulin analogs.

Clinical Trials of Linjeta^TM

We have conducted Phase 1, Phase 2 and Phase 3 clinical trials comparing the performance of our Linjeta^TM formulation of RHI to either Humulin^® R, which is a branded formulation of RHI, or Humalog^®, which is one of the largest selling rapid-acting insulin analogs in the United States. In our Phase 1 and Phase 2 clinical trials, we observed that the Linjeta^TM formulation was more rapidly absorbed than Humulin^® R or Humalog^®. Accordingly, we believe that our ultra-rapid acting formulations better simulate the natural first-phase insulin release in response to a meal that would be typical of healthy individuals.

We completed our two pivotal Phase 3 clinical trials of Linjeta^TM in July 2008. Our pivotal Phase 3 clinical trials were open-label, parallel group, randomized trials conducted at centers in the United States,

6

Germany and India. The trials were designed to compare the efficacy and safety of Linjeta^TM to Humulin^® R. One of the trials tested Linjeta^TM in patients with Type 1 diabetes and the other in patients with Type 2 diabetes. We enrolled more than 400 patients in each trial for a six month treatment period. Approximately one-half of the patients in each trial were treated with Linjeta^TM and the remainder with Humulin^® R. The primary objective of the trials was to determine if Linjeta^TM was not inferior to Humulin^® R in the management of blood glucose levels, as measured by the mean change in patients' HbA1c levels from baseline to the end of the trial. HbA1c levels are a measure of patients' average blood glucose levels over a period of approximately 3 months. HbA1c is the FDA's preferred endpoint for diabetes trials. Predefined secondary endpoints in the trials included rates of mild and moderate and severe hypoglycemic events, and changes in body weight. Approximately 400 patients with Type 1 and Type 2 diabetes who completed the pivotal Phase 3 clinical trials elected to participate in a long term safety extension trial in which all patients were treated with Linjeta^TM as their mealtime insulin. The last patient visit in the extension trial was in February 2010.

In December 2009, we submitted an NDA to the FDA under section 505(b)(2) of the FFDCA for clearance to market Linjeta^TM as a treatment for diabetes. In November 2010, the FDA issued a complete response letter requesting additional information regarding our NDA for Linjeta^TM. The complete response letter included comments related to clinical trials, statistical analysis and chemistry, manufacturing and controls and tolerability issues relating to localized discomfort upon injection. The FDA requested that we conduct two new Phase 3 clinical trials using our preferred commercial formulation of Linjeta^TM, one in patients with Type 1 diabetes and the other in patients with Type 2 diabetes prior to resubmitting the NDA.

Development of Additional RHI- and Insulin Analog-Based Formulations

Based upon the complete response letter and subsequent feedback that the FDA provided to us, we decided to study newer RHI-based formulations in earlier stage clinical trials. After reviewing the results of a Phase 1 clinical trial of two newer formulations, BIOD-105 and BIOD-107, we determined that the overall pharmacokinetic and pharmacodynamic profiles of these formulations did not demonstrate our target product profile. We subsequently conducted a Phase 1 clinical trial of two additional formulations, BIOD-123 and BIOD-125, and announced top-line results from that trial in April 2012. We determined that both formulations achieved our target pharmacokinetic, pharmacodynamic and toleration profiles.

The Phase 1 clinical trial of BIOD-123 and BIOD-125 evaluated the pharmacokinetic, pharmacodynamic and injection site toleration profiles of these product candidates relative to Humalog^®, a rapid-acting insulin analog. The objective of the clinical trial was to identify an RHI-based formulation with pharmacokinetic and pharmacodynamic profiles similar to the Linjeta^TM formulation, but with improved injection site toleration characteristics. The clinical trial was a single-center, randomized, double-blind, three-period crossover trial in 12 patients with Type 1 diabetes. Each study drug was administered subcutaneously on separate days with a washout period between injections. In the Phase 1 clinical trial, absorption rates of BIOD-123 and BIOD-125 were significantly faster than that of Humalog^® as indicated by 64% and 54% reductions, respectively, in mean times to half maximal insulin concentrations (p < 0.001 for both BIOD-123 and BIOD-125 compared to Humalog^®). Both RHI-based formulations and Humalog^® were well tolerated, with injection site toleration generally perceived by patients to be similar to that of their usual mealtime injections used at home. As measured on a 100 mm visual analog scale, or VAS, in which 100 mm is defined as the worst possible injection discomfort, local toleration was not significantly different for BIOD-123 compared to Humalog^® (BIOD-123 mean VAS 3.6 ± 2.1 mm, Humalog^® 1.8 ± 1.1 mm, p=NS). The VAS score for BIOD-125 was slightly higher as compared to Humalog^® (mean VAS 6.8 ± 2.9 mm, p < 0.05).

In the third calendar quarter of 2012 we began enrolling patients in a Phase 2 clinical trial of BIOD-123. The clinical trial was a randomized, open label, parallel group study conducted at 32 investigative centers in the United States. In the clinical trial, 132 patients with Type 1 diabetes were randomized to receive either BIOD-123 or Humalog® to use as their mealtime insulin during an 18-week treatment period. Both arms of the study used insulin glargine, sold as Lantus®, as the basal insulin. The clinical trial was designed to evaluate HbA1c control as the primary endpoint, and secondary endpoints included postprandial glucose excursions, glycemic variability, hypoglycemic event rates and weight changes. Following randomization, subjects entered a six-week dose titration period during which basal insulin and then prandial insulin doses were titrated in order to reach standard ADA recommended preprandial glucose targets. Upon completion of

7

the titration period, patients entered a "relative stable dosing period" for an additional 12 weeks. The trial completed patient dosing in the second calendar quarter of 2013.

The Phase 2 clinical trial of BIOD-123 completed patient dosing in the second calendar quarter of 2013, and in September 2013 we announced preliminary results from the trial. BIOD-123 achieved the primary endpoint of noninferiority for HbA1c relative to Humalog®. The mean HbA1c change from baseline in the BIOD-123 group was -0.08 ± 0.064% and -0.25± 0.063% in the Humalog® group. The 95% confidence interval (-0.01, 0.35) of the between group differences in change from baseline HbA1c did not exceed the FDA-designated threshold of 0.40%, thereby establishing non-inferiority. HbA1c change during the stable dosing period was similar in both treatment groups. During this period, the mean change in HbA1c in the BIOD-123 group was -0.01% and in the Humalog® group was +0.02%. Additionally, we observed comparable weight gain, mean hypoglycemia event rates and postprandial glucose excursions between the treatment groups, as well as some trends in favor of BIOD-123 in regard to postprandial glucose excursions to a liquid meal challenge test and weight gain during the stable dosing period. Comparable safety and adverse event profiles were observed in the clinical trial, with the exception of an increased frequency of injection site pain associated with BIOD-123, which appeared to be clinically minor, short-lived and distinctly superior to the toleration profile we observed with Linjeta™ in our earlier Phase 3 clinical trials. We expect to provide an update on our further development plans for BIOD-123 after completing our analysis of the data from the Phase 2 clinical and following discussions with FDA on clinical trial design, safety and chemistry, manufacturing and controls relating to potential future studies.

In addition to BIOD-123, we have other RHI-based formulations in earlier stages of development. In particular, we are developing ultra-rapid-acting formulations of concentrated insulin that are characterized by a rapid onset of action and a prolonged duration of action. We believe these formulations could address an unmet medical need for an insulin with an initial rate of absorption superior to that of Humulin® R U-500 and prandial/basal pre-mixed insulins. In November 2013, we announced that we had initiated a Phase 1 clinical trial with BIOD-531, our lead candidate for an ultra-rapid-acting concentrated insulin formulation. BIOD-531 contains 400 units of RHI per milliliter (instead of the standard 100 units per milliliter), and is formulated with EDTA, citrate and magnesium sulfate. In preclinical studies in diabetic swine, BIOD-531 demonstrated a more rapid rate of absorption and onset of action, along with a similar duration of action, when compared to Humulin® R U-500, a presentation containing 500 units of RHI per millimeter. In other preclinical studies, BIOD-531 also demonstrated a more rapid rate of absorption and onset of action when compared to Humalog® pre-mixed prandial/basal formulations. In the Phase 1 clinical trial of BIOD-531, we will evaluate and compare the onset and duration of action and injection site tolerability of BIOD-531 to Humulin® R U-500 and to Humalog® prandial/basal pre-mixed insulin. We anticipate reporting top line data from the clinical trial in the first calendar quarter of 2014.

We also continue to develop ultra-rapid-acting insulin analog-based formulations. In January 2013, we announced top-line results from our Phase 1 clinical trial of two insulin analog-based formulations, BIOD-238 and BIOD-250. These formulations, which were manufactured using commercial preparations of Humalog®, use the same combination of or similar excipients as BIOD-123 and were intended to be optimized for rapid absorption and injection site toleration. The trial, which was conducted in Australia, was designed to compare the pharmacokinetic and injection site toleration profiles of BIOD-238 and BIOD-250 relative to Humalog®. In the trial, both formulations met our target pharmacokinetic profile for an ultra-rapid-acting insulin analog-based formulation, and BIOD-250 met our target injection site toleration profile. We do not expect to study these formulations in additional clinical trials because they were formulated by adding our proprietary excipients to the marketed formulation of Humalog® and because they do not demonstrate stability characteristics consistent with our target product profile. Accordingly, we are continuing our insulin analog-based formulation work to develop formulations using insulin lispro as the active pharmaceutical ingredient, rather than a marketed presentation of Humalog®.

Our Development of a Glucagon Rescue Product

We believe that the complexity of the currently available rescue kits and the training required for proper administration of glucagon using those kits has resulted in the underuse of glucagon as a rescue treatment for diabetes patients experiencing severe hypoglycemia. We also believe that the development of room temperature stable presentations or liquid formulations of glucagon can overcome the limitations resulting

8

from the rescue kits. In June 2013, we announced plans to develop a novel glucagon rescue product to treat severe hypoglycemia using a proprietary device from Unilife Corporation. The device, which is being customized for use in emergency situations by patient caregivers with no medical training, is a dual-chamber design that automatically reconstitutes lyophilized glucagon with a liquid diluent immediately prior to injection, and it features automatic needle retraction on full dose delivery. We expect to submit an Investigational New Drug application to the FDA for our dual-chamber glucagon rescue product during the next nine months and anticipate conducting a pivotal clinical trial in the second half of 2014. We are also using other proprietary technologies to develop a liquid glucagon formulation that does not require reconstitution and could, therefore, be administered using a pre-filled syringe in an autoinjector or similar device.

Government Regulation

The FDA and other federal, state, local and foreign regulatory agencies impose substantial requirements upon the clinical development, approval, labeling, manufacture, marketing and distribution of drug products. These agencies regulate, among other things, research and development activities and the testing, approval, manufacture, quality control, safety, effectiveness, labeling, storage, record keeping, advertising and promotion of our product candidates. The regulatory approval process is generally lengthy and expensive, with no guarantee of a positive result. Moreover, failure to comply with applicable FDA or other requirements may result in civil or criminal penalties, recall or seizure of products, injunctive relief including partial or total suspension of production, or withdrawal of a product from the market.

United States Government Regulation

The FDA regulates, among other things, the research, manufacture, promotion and distribution of drugs in the United States under the FFDCA and other statutes and implementing regulations. We intend to seek FDA approval for our product candidates in an NDA, and not under an application submitted for approval as a biologic under the Public Health Service Act. The process required by the FDA before a drug product candidate may be marketed in the United States under an NDA generally involves the following:

•completion of extensive nonclinical laboratory tests, animal studies and formulation studies, all performed in accordance with the FDA's Good Laboratory Practice, or GLP, regulations;

•submission to the FDA of an investigational new drug application, or IND, which must become effective before human clinical trials may begin;

•for some products, performance of adequate and well-controlled human clinical trials in accordance with the FDA's regulations, including Good Clinical Practices, to establish the safety and efficacy of the product candidate for each proposed indication;

•submission to the FDA of an NDA, and the acceptance for filing of the NDA by the FDA;

•satisfactory completion of an FDA preapproval inspection of the manufacturing facilities at which the product is produced to assess compliance with current Good Manufacturing Practice, or cGMP, regulations; and

•FDA review and approval of the NDA prior to any commercial marketing, sale or shipment of the drug.

The testing and approval process requires substantial time, effort and financial resources, and we cannot be certain that any approvals for our product candidates will be granted on a timely basis, if at all.

Nonclinical tests include laboratory evaluations of product chemistry, formulation and stability, as well as studies to evaluate toxicity in animals and other animal studies. The results of nonclinical tests, together with manufacturing information and analytical data, are submitted as part of an IND to the FDA. Some nonclinical testing may continue even after an IND is submitted. The IND also includes one or more protocols for the initial clinical trial or trials and an investigator's brochure. An IND automatically becomes effective 30 days after receipt by the FDA, unless the FDA, within the 30-day time period, raises concerns or questions relating to the proposed clinical trials as outlined in the IND and places the clinical trial on a clinical hold. In such cases, the IND sponsor and the FDA must resolve any outstanding concerns or questions before any clinical

9

trials can begin. A clinical trial hold also may be imposed at any time before or during studies due to safety concerns or non-compliance with regulatory requirements. An independent institutional review board, or IRB, monitors the clinical centers proposing to conduct the clinical trial and must review and approve the plan for any clinical trial before it commences. An IRB considers, among other things, whether the risks to individuals participating in the trials are minimized and are reasonable in relation to anticipated benefits. The IRB also approves the informed consent form signed by the trial participants and must monitor the study until completed.

Clinical Trials. Clinical trials involve the administration of the product candidate to human subjects under the supervision of qualified medical investigators according to approved protocols that detail the objectives of the study, dosing procedures, subject selection and exclusion criteria, and the parameters to be used to monitor participant safety. Each protocol is submitted to the FDA as part of the IND.

Human clinical trials are typically conducted in three sequential phases, but the phases may overlap, or be combined.

•Phase 1 clinical trials typically involve the initial introduction of the product candidate into human volunteers. In Phase 1 clinical trials, the product candidate is typically tested for safety, dosage tolerance, absorption, metabolism, distribution, excretion and pharmacodynamics.

•Phase 2 clinical trials are conducted in a limited patient population to gather evidence about the efficacy of the product candidate for specific, targeted indications, to determine dosage tolerance and optimal dosage, and to identify possible adverse effects and safety risks.

•Phase 3 clinical trials are undertaken to evaluate clinical efficacy and to test for safety in an expanded patient population at geographically dispersed clinical trial sites. The size of Phase 3 clinical trials depends upon clinical and statistical considerations for the product candidate and proposed indications, but sometimes can include several thousand patients. Phase 3 clinical trials are intended to establish the overall risk-benefit ratio of the product candidate and provide an adequate basis for product labeling.

Clinical testing must satisfy extensive FDA regulations. Reports detailing the status of the clinical trials must be submitted at least annually to the FDA and safety reports must be submitted for serious and unexpected adverse events. Success in early stage clinical trials does not assure success in later stage clinical trials. The FDA, an IRB or we may suspend a clinical trial at any time on various grounds, including a finding that the research subjects or patients are being exposed to an unacceptable health risk.

New Drug Applications. Assuming successful completion of the required clinical trials, the results of product development, nonclinical studies and clinical trials are submitted to the FDA as part of an NDA. An NDA also must contain extensive manufacturing information, as well as proposed labeling for the finished product. An NDA must contain information about the chemistry and physical characteristics of the drug and a final process for manufacturing the product in accordance with cGMP. The manufacturing process must be capable of consistently producing quality product within specifications approved by the FDA. The manufacturer must develop methods for testing the quality, purity and potency of the final product. In addition, appropriate packaging must be selected and tested and stability studies must be conducted to demonstrate that the product does not undergo unacceptable deterioration over its shelf life. Prior to approval, the FDA will conduct an inspection of the manufacturing facilities to assess compliance with cGMP.

The FDA reviews all NDAs submitted before it accepts them for filing. The FDA may request additional information rather than accept an NDA for filing. In this event, the NDA must be resubmitted with the additional information and is subject to review before the FDA accepts it for filing. After an application is filed, the FDA may refer the NDA to an advisory committee for review, evaluation and recommendation as to whether the application should be approved and under what conditions. The FDA is not bound by the recommendation of an advisory committee, but it considers them carefully when making decisions. The FDA may deny approval of an NDA if the applicable regulatory criteria are not satisfied. Data obtained from clinical trials are not always conclusive and the FDA may interpret data differently than we interpret the same data. The FDA may issue a complete response letter, which may require additional clinical or other data or impose other conditions that must be met in order to secure final approval of the NDA. An applicant receiving a complete response letter may resubmit the application with data and information addressing the FDA's concerns or requirements, withdraw the application without prejudice to a subsequent submission of a related

10

application or request a hearing on whether there are grounds for denying approval of the application. If a product receives regulatory approval, the approval may be significantly limited to specific diseases and dosages or the indications for use may otherwise be limited, which could restrict the commercial value of the product. In addition, the FDA may require us to conduct Phase 4 testing which involves clinical trials designed to further assess a drug's safety and effectiveness after NDA approval, and may require surveillance programs to monitor the safety of approved products which have been commercialized. Once issued, the FDA may withdraw product approval if ongoing regulatory requirements are not met or if safety or efficacy questions are raised after the product reaches the market. The agency may also impose requirements that the NDA holder conduct new studies, make labeling changes, implement Risk Evaluation and Mitigation Strategies, and take other corrective measures.

Section 505(b)(2) NDAs. There are three types of drug registration applications: the full NDA, the abbreviated NDA, which is used for generic drug applications, and the Section 505(b)(2) NDA. We intend to file Section 505(b)(2) NDAs that might, if accepted by the FDA, save time and expense in the development and testing of our product candidates. A full NDA is submitted under Section 505(b)(1) of the FFDCA and must contain full reports of investigations conducted by the applicant to demonstrate the safety and effectiveness of the drug. A Section 505(b)(2) NDA may be submitted for a drug for which one or more of the investigations relied upon by the applicant was not conducted by or for the applicant and for which the applicant has no right of reference from the person by or for whom the investigations were conducted. A Section 505(b)(2) NDA may be submitted based in whole or in part on published literature or on the FDA's finding of safety and efficacy of one or more previously approved drugs, which are known as reference drugs. Thus, the filing of a Section 505(b)(2) NDA may result in approval of a drug based on fewer clinical or nonclinical studies conducted by the applicant than would be required under a full NDA. The number and size of studies that need to be conducted by the sponsor depends on the amount and quality of data pertaining to the reference drug that are publicly available, and on the similarity of and differences between the applicant's drug and the reference drug. In some cases, extensive, time-consuming, and costly clinical and nonclinical studies may still be required for approval of a Section 505(b)(2) NDA.

Because we are developing new formulations of previously approved chemical entities, such as insulin and glucagon, our drug approval strategy is to submit Section 505(b)(2) NDAs to the FDA. We plan to pursue similar routes for submitting applications for our product candidates in foreign jurisdictions if available. The FDA may not agree that our product candidates are approvable pursuant to Section 505(b)(2) NDAs. There is no specific guidance available for Section 505(b)(2) NDAs for insulin or glucagon. In addition, while there is precedent for a glucagon product being approved under a Section 505(b)(2) NDA, we are not aware of any insulin product that has been approved under a Section 505(b)(2) NDA. If the FDA determines that Section 505(b)(2) NDAs are not appropriate and that full NDAs are required for our product candidates, the time and financial resources required to obtain FDA approval for our product candidates could substantially and materially increase, and our product candidates might be less likely to be approved. If the FDA requires full NDAs for our product candidates, or requires more extensive testing and development for some other reason, our ability to compete with alternative products that arrive on the market more quickly than our product candidates would be adversely impacted.

Patent Protections. An applicant submitting a Section 505(b)(2) NDA must certify to the FDA with respect to the patent status of the reference drug upon which the applicant relies in support of approval of its drug. With respect to every patent listed in the FDA's Orange Book, which is the FDA's list of approved drug products, as claiming the reference drug or an approved method of use of the reference drug, the Section 505(b)(2) applicant must certify that: (1) there is no patent information listed by the FDA for the reference drug; (2) the listed patent has expired; (3) the listed patent has not expired, but will expire on a particular date; (4) the listed patent is invalid, unenforceable, or will not be infringed by the manufacture, use, or sale of the product in the Section 505(b)(2) NDA; or (5) if the patent is a use patent, that the applicant does not seek approval for a use claimed by the patent. If the applicant files a certification to the effect of clause (1), (2) or (5), FDA approval of the Section 505(b)(2) NDA may be made effective immediately upon successful FDA review of the application, in the absence of marketing exclusivity delays, which are discussed below. If the applicant files a certification to the effect of clause (3), the Section 505(b)(2) NDA approval may not be made effective until the expiration of the relevant patent and the expiration of any marketing exclusivity delays.

If the Section 505(b)(2) NDA applicant provides a certification to the effect of clause (4), referred to as a paragraph IV certification, the applicant also must send notice of the certification to the patent owner and the

11

holder of the NDA for the reference drug. The filing of a patent infringement lawsuit within 45 days of the receipt of the notification may prevent the FDA from approving the Section 505(b)(2) NDA for 30 months from the date of the receipt of the notification unless a court determines that a longer or shorter period is appropriate because either party to the action failed to reasonably cooperate in expediting the action. However, the FDA may approve the Section 505(b)(2) NDA before the 30 months have expired if a court decides that the patent is invalid, unenforceable, or not infringed, or if a court enters a settlement order or consent decree stating the patent is invalid or not infringed.

Notwithstanding the approval of many products by the FDA pursuant to Section 505(b)(2), over the last few years certain pharmaceutical companies and others have objected to the FDA's interpretation of Section 505(b)(2). If the FDA's interpretation of Section 505(b)(2) is successfully challenged in court, the FDA may be required to change its interpretation of Section 505(b)(2) which could delay or even prevent the FDA from approving any Section 505(b)(2) NDA that we submit. The pharmaceutical industry is highly competitive, and it is not uncommon for a manufacturer of an approved product to file a citizen petition with the FDA seeking to delay approval of, or impose additional approval requirements for, pending competing products. If successful, such petitions can significantly delay, or even prevent, the approval of the new product. Moreover, even if the FDA ultimately denies such a petition, the FDA may substantially delay approval while it considers and responds to the petition.

Marketing Exclusivity. Marketing exclusivity provisions under the FFDCA can delay the submission or the approval of Section 505(b)(2) NDAs, thereby delaying a product approved under Section 505(b)(2) from entering the market. The FFDCA provides five-year marketing exclusivity to the first applicant to gain approval of an NDA for a new chemical entity, or NCE, meaning that the FDA has not previously approved any other drug containing the same active moiety. This exclusivity generally prohibits the submission of a Section 505(b)(2) NDA for any drug product containing the active moiety during the five-year exclusivity period. However, submission of a Section 505(b)(2) NDA that certifies that a listed patent is invalid, unenforceable, or will not be infringed, as discussed above, is permitted after four years. In that case, if a patent infringement lawsuit is brought within 45 days after such certification, FDA approval of the Section 505(b)(2) NDA may automatically be stayed until 7.5 years after the NCE approval date. The FFDCA also provides three years of marketing exclusivity for the approval of new and supplemental NDAs for product changes, including, among other things, new indications, dosage forms, routes of administration or strengths of an existing drug, or for a new use, if new clinical investigations, other than bioavailability studies, that were conducted or sponsored by the applicant are deemed by the FDA to be essential to the approval of the application. Five-year and three-year exclusivity will not delay the submission or approval of another full NDA; however, as discussed above, an applicant submitting a full NDA under Section 505(b)(1) would be required to conduct or obtain a right of reference to all of the preclinical and adequate and well-controlled clinical trials necessary to demonstrate safety and effectiveness.

Other types of exclusivity in the United States include orphan drug exclusivity and pediatric exclusivity. The FDA may grant orphan drug designation to a drug intended to treat a rare disease or condition, which is generally a disease or condition that affects fewer than 200,000 individuals in the United States, or more than 200,000 individuals in the United States and for which there is no reasonable expectation that the cost of developing and making available in the United States a drug for this type of disease or condition will be recovered from sales in the United States for that drug. Seven-year orphan drug exclusivity is available to a product that has orphan drug designation and that receives the first FDA approval for the indication for which the drug has such designation. Orphan drug exclusivity prevents approval of another application for the same drug for the same orphan indication, for a period of seven years, regardless of whether the application is a full NDA or a Section 505(b)(2) NDA, except in limited circumstances, such as a showing of clinical superiority to the product with orphan exclusivity. Pediatric exclusivity, if granted, provides an additional six months to an existing exclusivity or statutory delay in approval resulting from a patent certification. This six-month exclusivity, which runs from the end of other exclusivity protection or patent delay, may be granted based on the completion of a pediatric study in accordance with an FDA-issued "Written Request" for such a study.

Section 505(b)(2) NDAs are similar to full NDAs filed under Section 505(b)(1) in that they are entitled to any of these forms of exclusivity if they meet the qualifying criteria. They also are entitled to the patent protections described above, based on patents that are listed in the FDA's Orange Book, in the same manner as patents claiming drugs and uses approved for NDAs submitted as full NDAs.

12

Other Regulatory Requirements. Maintaining substantial compliance with appropriate federal, state and local statutes and regulations requires the expenditure of substantial time and financial resources. Drug manufacturers are required to register their establishments with the FDA and certain state agencies, and after approval, the FDA and these state agencies conduct periodic unannounced inspections to ensure continued compliance with ongoing regulatory requirements, including cGMP. In addition, after approval, some types of changes to the approved product, such as adding new indications, manufacturing changes and additional labeling claims, are subject to further FDA review and approval. The FDA may require post-approval testing and surveillance programs to monitor safety and the effectiveness of approved products that have been commercialized. Any drug products manufactured or distributed by us pursuant to FDA approvals are subject to continuing regulation by the FDA, including:

•record-keeping requirements;

•reporting of adverse experiences with the drug;

•providing the FDA with updated safety and efficacy information;

•reporting on advertisements and promotional labeling;

•drug sampling and distribution requirements; and

•complying with electronic record and signature requirements.

In addition, the FDA strictly regulates labeling, advertising, promotion and other types of information on products that are placed on the market. There are numerous regulations and policies that govern various means for disseminating information to health-care professionals as well as consumers, including to industry sponsored scientific and educational activities, information provided to the media and information provided over the Internet. Drugs may be promoted only for the approved indications and in accordance with the provisions of the approved label.

The FDA has very broad enforcement authority and the failure to comply with applicable regulatory requirements can result in administrative or judicial sanctions being imposed on us or on the manufacturers and distributors of our approved products, including warning letters, refusals of government contracts, clinical holds, civil penalties, injunctions, restitution, and disgorgement or profits, recall or seizure of products, total or partial suspension of production or distribution, withdrawal of approvals, refusal to approve pending applications, and criminal prosecution resulting in fines and incarceration. The FDA and other agencies actively enforce the laws and regulations prohibiting the promotion of off-label uses, and a company that is found to have improperly promoted off-label uses may be subject to significant liability. In addition, even after regulatory approval is obtained, later discovery of previously unknown problems with a product may result in restrictions on the product or even complete withdrawal of the product from the market.

Regulations Outside the United States

In addition to regulations in the United States, we will be subject to a variety of laws and regulations in other jurisdictions governing clinical trials and commercial sales and distribution of our products. Whether or not we obtain FDA approval for a product, we must obtain the necessary approvals by the comparable regulatory authorities of countries outside the United States before we can commence clinical trials or marketing of the product in those countries. The approval process varies from country to country, and the time may be longer or shorter than that required for FDA approval. The requirements governing the conduct of clinical trials, product licensing, pricing and reimbursement also vary between jurisdictions.

To obtain regulatory approval of a drug under European Union regulatory systems, we may submit applications for marketing authorizations either under a centralized or decentralized procedure. The centralized procedure is compulsory for medicines produced by certain biotechnological processes, new active substances indicated for the treatment of certain diseases such as AIDS, cancer, neurodegenerative disorders and diabetes, and products designated as orphan medicinal products, and optional for other new active substances and those products which constitute a significant therapeutic, scientific or technical innovation. The procedure provides for the grant of a single marketing authorization that is valid for all European Union member states, as well as for Iceland, Liechtenstein, and Norway. The decentralized procedure provides for approval by one or more other, or concerned, member states of an assessment of an application performed by one member state, known

13

as the reference member state. Under this procedure, an applicant submits an application, or dossier, and related materials including a draft summary of product characteristics, and draft labeling and package leaflet, to the reference member state and concerned member states. The reference member state prepares a draft assessment and drafts of the related materials within 120 days after receipt of a valid application. Within 90 days of receiving the reference member state's assessment report, each concerned member state must decide whether to approve the assessment report and related materials. If a member state cannot approve the assessment report and related materials on the grounds of potential serious risk to the public health, the disputed points may eventually be referred to the European Commission, whose decision is binding on all member states.

Competition

The pharmaceutical industry is characterized by intense competition and rapidly evolving technology. Many large pharmaceutical and biotechnology companies, academic institutions, governmental agencies and other public and private research organizations are pursuing the development of novel drugs and drug formulations that target endocrine disorders. If approved, our product candidates will compete against many products with similar indications.

If approved, the primary competition for our ultra-rapid-acting insulin formulations will be rapid-acting mealtime injectable insulins. There are several approved injectable rapid-acting mealtime insulin analogs currently on the market including Humalog®, marketed by Eli Lilly and Company, NovoLog®, marketed by Novo Nordisk, and Apidra®, marketed by Sanofi-Aventis. These rapid-acting insulin analogs provide improvement over regular forms of mealtime insulin, including faster subcutaneous absorption, an earlier and greater insulin peak and more rapid post-peak decrease. Both Humalog® and NovoLog® have limited remaining patent protection in the United States and Europe. The possible introduction of lower priced brands or substitutable generic versions of these products could negatively impact the revenue potential of our ultra-rapid-acting product candidates should any be approved.

In addition, other development stage insulin formulations may be approved and compete with ours. Halozyme Therapeutics, Inc. has conducted a Phase 1 and multiple Phase 2 clinical trials of RHI, lispro (the insulin analog in Humalog®) and aspart (the insulin analog in NovoLog®) in combination with a recombinant human hyaluronidase enzyme and has reported that in each case the combination yielded pharmacokinetics and glucodynamics that better mimicked physiologic mealtime insulin release and activity than RHI, Humalog® or NovoLog® alone. Halozyme is currently conducting a clinical trial with approximately 400 patients examining the effects of a preinfusion of hyaluronidase prior to the use of an insulin pump. In 2011, Eli Lilly partnered with a French biotechnology company, Adocia Inc., to develop an insulin analog that would demonstrate a more rapid onset of action. In 2013, Eli Lilly returned all rights to the program to Adocia. Adocia subsequently announced the start of a clinical trial in support of the development of a pre-mixed prandial/basal insulin. Additionally, Novo Nordisk has reported that they have initiated clinical development of an insulin analog intended to provide faster onset of action than the currently available rapid-acting insulin analogs and that a candidate formulation will enter Phase 3 clinical trials in late 2013.

Several companies are also developing alternative insulin systems for diabetes, including MannKind Corporation, which submitted an NDA in early 2009 for an inhalable insulin product candidate. Mannkind's product candidate was not approved by the FDA and MannKind subsequently conducted and completed two additional Phase 3 clinical trials to support a revised NDA. The primary endpoints were met in both trials, and in October 2013 the FDA accepted the resubmission of an NDA for Mannkind's inhaled insulin product candidate. Approval of an inhaled insulin could reduce the overall market for injectable mealtime insulin.

A stable glucagon presentation for use as a rescue treatment for diabetes patients experiencing severe hypoglycemia would also face significant competition if it were to be commercialized. Eli Lilly and Novo Nordisk currently market injectable glucagon rescue kit products. We are aware of several glucagon rescue product candidates in early stage development, such as a potentially competitive auto-injector device being developed by Enject Corporation that integrates glucagon powder and a diluent into a dual-chamber cartridge within that device. Xeris Corporation is developing an auto-injector utilizing a concentrated, non-aqueous glucagon formulation, which currently being studied in a clinical trial. In addition, other companies with expertise in protein stabilization, including Latitude Pharmaceuticals, have announced that they have

14

developed a stable glucagon formulation using FDA-approved injectable ingredients. We believe that an intranasal formulation of glucagon is being studied in one or more clinical trials. All of these programs utilize the same active pharmaceutical ingredient as the stable glucagon presentations that we are developing and offer, or may offer, presentations allowing for room temperature storage. In addition, Eli Lilly, Novo Nordisk and Zealand Pharma A/S, a pharmaceutical company based in Denmark, may be developing glucagon analogs, which may also offer advantages over our stable glucagon presentations.

Intellectual Property and Proprietary Technology

The technologies for our ultra-rapid-acting insulin formulations have been developed exclusively by our employees, without input from third parties.

In October 2007 the United States Patent and Trademark Office issued U.S. Patent No. 7,279,457 encompassing our ultra-rapid-acting insulin formulations. If all maintenance fees are paid, the patent will expire no earlier than January 2026. In addition, a related European Patent, EP 1 740 154, was granted in June 2009 and expires in March 2025 in the designated countries if all annuity fees are paid. Two additional European applications on this technology, EP2 319 500 and EP2 106 790, have been allowed. Related applications have been granted in Australia, Canada and Japan. Additional applications with claims directed to formulations containing insulin, insulin derivatives or analogs are currently pending in the U.S. and foreign patent offices.

Our pending patent applications, those we may file in the future, or those we may license from third parties, may not result in patents being issued.

The individual active and inactive ingredients in our ultra-rapid-acting insulin formulations and our liquid glucagon formulations have been known and used for many years and, therefore, are no longer subject to patent protection, except in proprietary combinations. Accordingly, our patent and pending applications are directed to the particular formulations of these ingredients in our products, and to their use. Although we believe our formulations and their uses are or will be patented and provide a competitive advantage, our patents may not prevent others from marketing formulations using the same active and inactive ingredients in similar but different formulations.

We have entered into an agreement with Aegis Therapeutics, LLC, or Aegis, to acquire an exclusive, sublicensable, worldwide license to the protein stabilization technology that we are using in the development of our liquid glucagon formulations. Under the terms of the agreement, Aegis will prepare, file, prosecute and maintain patents and patent applications that are specific to our liquid glucagon formulations in jurisdictions that we may designate from time to time.

We have entered into a customization and commercial supply agreement with Unilife Medical Solutions, Inc., a wholly owned subsidiary of Unilife Corporation, to acquire an exclusive, sublicensable, worldwide license to a proprietary device platform of dual-chamber devices for use with glucagon. Under the terms of the agreement, Unilife Medical Solutions, Inc. will control the patent protection relating to the devices and be the sole owner of improvements thereto.

We require our employees and consultants to execute confidentiality agreements upon the commencement of employment, consulting or collaborative relationships with us. These agreements provide that all confidential information developed or made known during the course of the relationship with us be kept confidential and not disclosed to third parties except in specific circumstances. In the case of employees, the agreements provide that all inventions resulting from work performed for us, utilizing our property or relating to our business and conceived or completed by the individual during employment shall be our exclusive property to the extent permitted by applicable law.

Manufacturing

We do not have the facilities required to manufacture our product candidates for use in clinical trials. Therefore, we intend to manufacture our product candidates by contracting with third parties that operate manufacturing facilities in accordance with cGMP.

We have contracted with N.V. Organon, a global producer of insulin, to supply us with all of the insulin that we will need for the testing and manufacturing of our RHI-based formulations. Our agreement with N.V.

15

Organon will terminate in June 2018. We believe that our current supplies of insulin, together with the quantities of insulin called for under our existing supply agreement, will be sufficient to allow us to complete our current and anticipated future clinical trials of our proprietary RHI-based formulations.

With regard to our insulin analog-based formulations, we have entered into an agreement with a pharmaceutical company to acquire a limited supply of an insulin analog for use as the active pharmaceutical ingredient in our proprietary formulations. In addition, we have conducted some development work and all of our clinical trials of our insulin analog-based formulations by combining our proprietary excipients with a marketed presentation of an insulin analog.

We have entered into a commercial supply agreement with Bachem AG, a Swiss corporation, for the supply of all of the glucagon we will need for the testing and manufacturing of our dual-chamber glucagon rescue product candidate and our liquid glucagon formulations. The initial term of our agreement with Bachem AG will expire in July 2017. We believe that the quantities of glucagon that we have rights to acquire under this agreement will be sufficient to allow us to complete our current and anticipated future clinical trials of our glucagon rescue product candidates and to support the commercial launch of our dual-chamber glucagon rescue product candidate.

We have entered into a customization and commercial supply agreement with Unilife Medical Solutions, Inc., a wholly owned subsidiary of Unilife Corporation, to acquire an exclusive, sublicensable, worldwide license to a proprietary device platform of dual-chamber devices for use with glucagon. Under the terms of the agreement, Unilife Medical Solutions, Inc., will develop and be the sole supplier of the device intended for use with our dual-chamber glucagon rescue product candidate. The initial term of our agreement with Unilife Medical Solutions, Inc. will expire in 2028.

Sales and Marketing

We currently have no sales and marketing capabilities and no distribution capabilities. Our current strategy is to selectively enter into collaboration agreements with leading pharmaceutical or biotechnology companies for the commercialization of our product candidates.

Employees

At November 30, 2013 we had 35 full time-employees who perform services for us on a regular basis. We consider our employee relations to be good.

ITEM 1A. RISK FACTORS

Risks Related to Our Financial Position and Need for Additional Capital

We have incurred significant losses since our inception. We expect to incur losses for the foreseeable future and may never achieve or maintain profitability.

Since our inception in December 2003, we have incurred significant operating losses. Our net losses were approximately $19.3 million for the fiscal year ended September 30, 2013. As of September 30, 2013, we had a deficit accumulated during the development stage of approximately $215.4 million. We have invested a significant portion of our efforts and financial resources in the development of our ultra-rapid-acting RHI-based insulin product candidates, including our prior Linjeta™ formulation and our current lead formulation, BIOD-123. More recently, we have begun to invest an increasing portion of our efforts and financial resources in the development of our ultra-rapid-acting insulin analog-based formulations, including BIOD-238 and BIOD-250, our concentrated insulin formulations and our stable glucagon presentations.

We expect to continue to incur significant operating losses for at least the next several years as we may:

•conduct clinical trials to study RHI- and insulin analog-based ultra-rapid-acting formulations that may have different pharmacokinetic and pharmacodynamic profiles and be associated with less injection site discomfort than the Linjeta™ formulation;

•conduct additional formulation development work to improve the stability, pharmacokinetic, and pharmacodynamic properties of our ultra-rapid-acting insulin analog-based formulations, our concentrated insulin formulations and our liquid glucagon formulations, or purchase rights related to proprietary technologies that are compatible with our product candidates;

•conduct the development work necessary to finalize the formulation and design of our dual-chamber glucagon rescue product candidate, as well as the preclinical studies, clinical trials and manufacturing activities necessary to support the filing of an NDA to the FDA for that product candidate;

•conduct later stage clinical trials of our ultra-rapid-acting insulin formulations and a stable glucagon presentation, including one or more pivotal clinical trials required for FDA approval of the NDAs;

•produce validation and registration batches of our product candidates to support one or more NDAs;

•conduct the required stability, preclinical and human factors and user acceptability studies to support the approval of one or more insulin pen and glucagon injection devices intended for use with our product candidates;

•purchase active pharmaceutical ingredients and other materials consistent with our existing contractual obligations; and

•conduct clinical development of our other product candidates.

To become and remain profitable, we must succeed in developing and eventually commercializing drugs with significant market potential. This will require us to be successful in a range of challenging activities, including developing proprietary insulin and glucagon product candidates with desirable pharmacokinetic, pharmacodynamic, stability and injection site toleration characteristics and then successfully completing preclinical testing and clinical trials for these formulations, obtaining regulatory approval for these formulations and manufacturing, marketing and selling those products for which we may obtain regulatory approval. We may never succeed in these activities and may never generate revenues that are significant or large enough to achieve profitability. Even if we do achieve profitability, we may not be able to sustain or increase profitability on a quarterly or annual basis. Our failure to become and remain profitable could depress the market price of our common stock and could impair our ability to raise capital, expand our business or continue our operations. A decline in the market price of our common stock could also cause you to lose all or a part of your investment.

18

We will need substantial additional funding and may be unable to raise capital when needed, which would force us to delay, reduce or eliminate our product development programs or commercialization efforts.

We are a development stage company with no commercial products. All of our product candidates are in early stages of development. Our product candidates will require significant additional clinical development, regulatory approvals and related investment before they can be commercialized. We expect to continue to incur significant research and development expenses as we continue our formulation work and advance these programs through clinical trials. Unless we are successful in consummating a strategic partnership to develop and commercialize an ultra-rapid-acting RHI- or insulin analog-based formulation or a stable glucagon presentation, we may need to raise substantial additional capital to develop and commercialize competitive products. Such financing may not be available on terms acceptable to us, or at all. If we are unable to obtain financing on favorable terms, our business, results of operations and financial condition may be materially adversely affected.

Based upon our current plans, we believe that our existing cash, cash equivalents and restricted cash will be sufficient to fund our anticipated operating expenses and capital expenditures through the second calendar quarter of 2015. However, we cannot assure you that our plans will not change or that changed circumstances will not result in the depletion of our capital resources more rapidly than we currently anticipate. Our future capital requirements will depend on many factors, including:

•the progress, timing or success of our research and development and clinical programs for our product candidates;

•the degree to which our ongoing assessment of the data from our recently completed Phase 2 clinical trial of BIOD-123, our lead candidate for an ultra-rapid-acting insulin formulation, and our related chemistry, manufacturing and controls development work, support further clinical development by us or our potential partners;

•our ability to successfully use the data from our Phase 2 clinical trial of BIOD-123 to design and conduct the pivotal clinical trials required by the FDA to secure approval to commercialize that candidate;

•the success of our formulation development work to improve the stability of our newer ultra-rapid-acting insulin analog-based formulations while maintaining the pharmacokinetic and injection site toleration characteristics associated with earlier formulations;

•our ability to conduct the development work necessary to finalize the formulation and design of our dual-chamber glucagon rescue product candidate, as well as the preclinical studies, clinical trials and manufacturing activities necessary to support the filing of an NDA to the FDA for that product candidate;

•the results of our real-time stability programs for our RHI-, insulin analog- and glucagon-based product candidates, including the reproducibility of earlier, smaller scale, stability studies and our ability to accurately project long term stability on the basis of accelerated testing;

•our ability to accurately anticipate technical challenges that we may face in the development of our ultra-rapid-acting RHI- and insulin analog-based product candidates or our glucagon rescue product candidates;

•our ability to secure approval by the FDA for our product candidates under Section 505(b)(2) of the FFDCA;

•our ability to enter into collaboration arrangements for the commercialization of our product candidates and the success or failure of any such collaborations into which we enter, or our ability to commercialize our product candidates ourselves;

•our ability to enforce our patents for our product candidates and our ability to secure additional patents for our product candidates;

•our ability to protect our intellectual property and operate our business without infringing upon the intellectual property rights of others;

19

•the degree of clinical utility of our product candidates, particularly with regard to our ultra-rapid-acting insulin formulations, which have not yet been shown to be clinically superior to existing rapid-acting insulin analogs;

•the emergence of competing technologies and products and other adverse market developments, such as advancements in glucagon stabilization technologies that could enable a room-temperature rescue product in a portable, easy to use presentation;

•the ability of our contract manufacturing organizations or collaborators to produce our products in our final dosage form;

•our ability to secure adequate supplies of active pharmaceutical ingredients to support our product development programs and, if successful, the commercialization one or more product candidates;

•our capabilities and strategies for manufacturing, marketing and commercializing a product candidate; and

•our ability to accurately estimate anticipated operating losses, future revenues, capital requirements and our needs for additional financing.

Until such time, if ever, as we can generate substantial product revenues, we expect to finance our cash needs through public or private equity offerings and debt financings, strategic collaborations and licensing arrangements. If we raise additional funds by issuing additional equity securities, our stockholders will experience dilution. Debt financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends. Any debt financing or additional equity that we raise may contain terms, such as liquidation and other preferences, which are not favorable to us or our stockholders. If we raise additional funds through collaboration, strategic alliance or licensing arrangements with third parties, it may be necessary to relinquish valuable rights to our technologies or product candidates, future revenue streams, research programs or product candidates or to grant licenses on terms that may not be favorable to us.

Our short operating history may make it difficult for you to evaluate the success of our business to date and to assess our future viability.

We commenced active operations in January 2004. Our operations to date have been limited to organizing and staffing our company, developing and securing our technology and undertaking preclinical studies and clinical trials of our product candidates. We have limited experience completing large-scale, pivotal clinical trials and we have not yet demonstrated our ability to obtain regulatory approval to market a product, manufacture a commercial scale product, or arrange for a third party to do so on our behalf, or conduct sales and marketing activities necessary for successful product commercialization. Consequently, any predictions you make about our future success or viability may not be as accurate as they could be if we had a longer operating history.

In addition, as a new business, we may encounter unforeseen expenses, difficulties, complications, delays and other known and unknown factors. We may need to transition from a company with a research focus to a company capable of supporting commercial activities. We may not be successful in such a transition.

Risks Related to the Development and Commercialization of Our Product Candidates

We have depended heavily on the success of our ultra-rapid-acting mealtime insulin development program.

We have invested a significant portion of our efforts and financial resources in the development of our ultra-rapid-acting insulin product candidates. The FDA concluded that the results from our completed pivotal Phase 3 clinical trials of Linjeta™ were not sufficient to obtain marketing approval for the Linjeta™ formulation, and we chose to advance new formulations into the clinic. Clinical trials of our first two new RHI-based formulations, BIOD-105 and BIOD-107, did not achieve satisfactory results. If we are not able to develop alternative RHI- or insulin-analog based formulations with desirable pharmacokinetic, pharmacodynamic, stability and injection site toleration characteristics, or experience significant delays in doing so, then our business may be materially harmed.

20

BIOD-123, our lead candidate for an ultra-rapid-acting RHI-based formulation, achieved the primary endpoint of noninferiority for HbA1c relative to Humalog® in a Phase 2 clinical, and patients in the two treatment groups demonstrated comparable results with regard to secondary endpoints, including weight gain, mean hypoglycemia event rates and postprandial glucose excursions. However, to date, we cannot conclude from our analysis of the data from the Phase 2 clinical trial that BIOD-123 will be shown to be clinically superior to existing rapid-acting insulin analogs in subsequent clinical trials. While evidence of superiority is not required to receive the FDA's approval to market BIOD-123, if we are unable to demonstrate clinical superiority to a rapid-acting analog in one or more secondary end points, such as weight gain, hypoglycemia event rates and postprandial glucose control, the commercial success of BIOD-123, as well as the interest of potential strategic partners, may be limited.

Our development of an RHI- or insulin analog-based formulation may not be successful; some formulations may have different regulatory requirements to obtain marketing approval from the FDA.

While we have significant experience with the technology we use to develop ultra-rapid-acting insulin formulations, our insulin-analog based formulations and concentrated RHI-based formulations are in early stages of development. Furthermore, we have manufactured only a small number of batches of BIOD-123 that we can use to project stability characteristics in a commercial scale manufacturing process, and we have observed that our most recent batches of BIOD-123 have not performed as well as earlier batches in our stability studies. We cannot assure you that our program to advance RHI- or insulin analog-based formulations will demonstrate pharmacokinetic, pharmacodynamic, stability and injection site toleration characteristics that are acceptable to us, a potential strategic partner or the FDA.

The regulatory requirements for any of our newer ultra-rapid-acting insulin formulations may not meet our expectations or may be different from those applicable to Linjeta™. For example, any concentrated insulin formulation we develop may be impacted by concerns about concentrated insulins in general, such as the risk that a patient would administer an incorrect dose of insulin that would induce severe hypoglycemia. Additionally, while BIOD-238 and BIOD 250, which were formulated by adding our proprietary excipients to the marketed presentation of Humalog®, were the subject of a Phase 1 clinical trial in Australia, we expect that we would need to conduct toxicology studies before advancing our insulin analog-based formulations into a Phase 1 clinical trial in the United States.

We have limited experience with developing pharmaceutical preparations of glucagon.

Our experience with the manufacture, testing and analysis of pharmaceutical preparations of glucagon in preclinical studies is limited, and we have not yet conducted any clinical trials using glucagon as an active pharmaceutical ingredient. Because of our limited experience, we may be unable to accurately anticipate the technical challenges that we may face in the development of a glucagon rescue product. For example, due to inconsistent results that we observed in our product candidate screening studies for a liquid glucagon formulation in the fourth calendar quarter of 2012, we decided to focus more of our resources in calendar year 2013 on developing our dual-chamber glucagon rescue product candidate.

The results of preclinical testing and clinical trials do not ensure success in future clinical trials or commercial success.

We have completed and released the results of our two pivotal Phase 3 clinical trials of Linjeta™. We have not completed the development of any products through commercialization. In October 2010, the FDA notified us that it would not approve our NDA for the Linjeta™ formulation, and we subsequently advanced alternate formulations, including BIOD-105, BIOD-107, BIOD-123, BIOD-125, BIOD-238 and BIOD-250 into the clinic and discontinued development of earlier formulations of Linjeta™. The outcomes of preclinical testing and clinical trials of prior formulations of Linjeta™ may not be predictive of the success of clinical trials with current or future formulations of our RHI- or insulin analog-based formulations. For example, despite promising preclinical data, BIOD-105 and BIOD-107 did not meet our preferred target product profile in Phase 1 clinical trials, and we discontinued development of these formulations. In addition, while the tolerability profile of BIOD-123 in a small Phase 1 clinical trial was comparable to that of Humalog®, in the recently completed Phase 2 clinical trial of BIOD-123, patients using BIOD-123 reported more incidences of injection site pain than those using Humalog®. We cannot assure you that the clinical trials of any of our RHI- or insulin analog-based formulations will ultimately be successful. New information regarding the safety, efficacy, toleration and stability of our RHI- or insulin analog-based formulations may arise that may be less favorable than the data observed to date.

21

If we are not successful in commercializing any of our product candidates, or are significantly delayed in doing so, our business will be materially harmed. The commercial success of our product candidates will depend on several factors, including the following:

•successful completion of preclinical development and clinical trials;

•our ability to identify and enroll patients who meet clinical trial eligibility criteria;

•receipt of marketing approvals from the FDA and similar regulatory authorities outside the United States;

•establishing that, with regard to an RHI- or insulin analog based-formulation, the formulation is well-tolerated in chronic use;

•establishing that, with regard to a stable glucagon presentation for use as a rescue product, the commercial presentation can be administered effectively by patient caregivers with limited or no training;

•establishing and maintaining commercial manufacturing capabilities and supplies of active pharmaceutical ingredients through arrangements with third-party manufacturers;

•launching commercial sales of the products, whether alone or in collaboration with others;

•competition from other products; and

•continued acceptable safety profiles of the products following approval.

If our clinical trials are delayed or do not produce positive results, we may incur additional costs and ultimately be unable to commercialize our product candidates.

Before obtaining regulatory approval for the sale of our product candidates, we must conduct, at our own expense, extensive preclinical tests to demonstrate the safety of our product candidates in animals and clinical trials to demonstrate the safety and efficacy of our product candidates in humans. Preclinical and clinical testing is expensive, difficult to design and implement, can take many years to complete and is uncertain as to outcome. A failure of one or more of our clinical trials of ultra-rapid-acting insulin formulations or stable glucagon presentations can occur at any stage of testing. We may experience numerous unforeseen events during our clinical trials that could delay or prevent our ability to receive regulatory approval or commercialize our product candidates, including:

•the number of patients required for our clinical trials may be larger than we anticipate, enrollment in our clinical trials may be slower than we currently anticipate, or participants may drop out of our clinical trials at a higher rate than we anticipate, any of which would result in significant delays;

•our third-party contractors may fail to comply with regulatory requirements or meet their contractual obligations to us in a timely manner;

•we might have to suspend or terminate our clinical trials if the participants are being exposed to unacceptable health risks;

•regulators or institutional review boards may require that we hold, suspend or terminate clinical research for various reasons, including noncompliance with regulatory requirements;

•the cost of our clinical trials may be greater than we anticipate;

•the supply, stability or quality of our product candidates or other materials necessary to conduct our clinical trials may be insufficient or inadequate; and

•the effects of our product candidates may not be the desired effects, may include undesirable side effects or the product candidates may have other unexpected characteristics.

If we are required to conduct additional clinical trials or other testing of our product candidates beyond those that we currently contemplate, if we are unable to successfully complete our clinical trials or other testing, if the results of these trials or tests are not positive or are only modestly positive or if there are safety concerns, we may:

22

•be delayed in obtaining or discontinue our efforts to obtain marketing approval;

•not be able to obtain marketing approval;

•obtain approval for indications that are not as broad as intended; or

•have the product removed from the market after obtaining marketing approval.

Our product development costs will also increase if we experience delays in testing or approvals. We do not know whether any preclinical tests or clinical trials will begin as planned, will need to be redesigned or will be completed on schedule, if at all. Significant preclinical or clinical trial delays also could shorten any periods during which we may have the exclusive right to commercialize our product candidates or allow our competitors to bring products to market before we do and impair our ability to commercialize our products or product candidates and may harm our business and results of operations.

If our product candidates are found to cause undesirable side effects we may need to delay or abandon our development and commercialization efforts.

Any undesirable side effects that might be caused by our product candidates could interrupt, delay or halt clinical trials and could result in the denial of regulatory approval by the FDA or other regulatory authorities for any or all targeted indications. In addition, if any of our product candidates receive marketing approval and we or others later identify undesirable side effects caused by the product, we could face one or more of the following:

•a change in the labeling statements or withdrawal of FDA or other regulatory approval of the product;

•a change in the way the product is administered; or

•the need to conduct additional clinical trials.

Any of these events could prevent us from achieving or maintaining market acceptance of the affected product or could substantially increase the costs and expenses of commercializing the product, which in turn could delay or prevent us from generating significant revenues from its sale.

The commercial success of any product candidates that we may develop will depend upon the degree of market acceptance by physicians, patients, healthcare payors and others in the medical community.

Any products that we bring to the market may not gain market acceptance by physicians, patients, healthcare payors and others in the medical community. If these products do not achieve an adequate level of acceptance, we may not generate significant product revenues and we may not become profitable. Physicians will not recommend our product candidates until clinical data or other factors demonstrate the safety and efficacy of our product candidates as compared to other treatments. Even if the clinical safety and efficacy of our product candidates are established, physicians may elect not to recommend these product candidates for a variety of reasons including the reimbursement policies of government and third-party payors, the effectiveness of our competitors in marketing their products and the possibility that patients may experience more injection site discomfort than they experience with competing products.

The degree of market acceptance of our product candidates, if approved for commercial sale, will depend on a number of factors, including:

•the willingness and ability of patients and the healthcare community to adopt our products;

•the ability to manufacture our product candidates in sufficient quantities with acceptable quality and to offer our product candidates for sale at competitive prices;

•the perception of patients and the healthcare community, including third-party payors, regarding the safety, efficacy and benefits of our product candidates compared to those of competing products or therapies;

•the convenience and ease of administration of our product candidates relative to existing treatment methods;

23

•the label and promotional claims allowed by the FDA, such as, in the case of an RHI- or insulin analog-based formulation, claims relating to glycemic control, hypoglycemia, weight gain, injection site discomfort, insulin pump compatibility, expiry dating and required handling conditions;

•the pricing and reimbursement of our product candidates relative to existing treatments; and

•marketing and distribution support for our product candidates.

Our ultra-rapid-acting insulin formulations have not yet been shown to be clinically superior to existing rapid-acting insulin analogs. It may be difficult for us to demonstrate superiority in the future because we anticipate that the primary endpoint of any pivotal clinical trial that we might conduct with an ultra-rapid-acting insulin product candidate would be non-inferiority to the comparator drug product. Furthermore, while BIOD-123 demonstrated a safety profile comparable to Humalog® in our Phase 2 clinical trial, we observed an increased frequency of injection site pain associated with BIOD-123. In all cases, the injection site pain appeared to be clinically minor, short-lived and distinctly superior to the toleration profile we observed with Linjeta™ in our earlier Phase 3 clinical trial. However, uncertainty with regard to the injection site toleration characteristics of BIOD-123 in larger scale clinical trials or upon commercialization, if approved by the FDA, may limit the appeal of this product candidate.

We are aware of other companies with expertise in protein stabilization that are developing stable glucagon presentations. If these formulations are easier to use than any product that we may develop, such as by allowing for room temperature storage in a smaller or more convenient device, our products, even if approved by the FDA, may not achieve commercial success.

The successful development of our product candidates may depend upon our ability to collaborate with or license technology from third parties.

Our ultra-rapid-acting insulin analog-based formulations and our stable glucagon presentations are at early stages of development. In order for us to meet our projected milestones for these programs, we must obtain reliable sources of active pharmaceutical ingredients and other related materials and supplies. Our leading candidates for a stable glucagon presentation are dependent upon licenses we have obtained to proprietary third-party technology, including the license we have obtained from Unilife Medical Solutions, Inc., a wholly owned subsidiary of Unilife Corporation, for a dual-chamber reconstitution device. The termination of these licenses may materially harm our efforts to commercialize a glucagon rescue product. We may also continue to study additional third-party proprietary stabilization technologies for use in these programs. Even if these studies are successful, we cannot assure you that we will be able to license any third-party technologies on terms that would be acceptable to us.

If we fail to enter into strategic collaborations for the commercialization of our product candidates or if our collaborations are unsuccessful, we may be delayed in our commercialization efforts; we may be required to establish our own sales, marketing, manufacturing and distribution capabilities which will be expensive, require additional capital we do not currently have, and could delay the commercialization of our product candidates and have a material and adverse effect on our business; we cannot commercialize our insulin analog-based formulations until all applicable third-party patents have expired.

A broad base of physicians, including primary care physicians, internists and endocrinologists, treat patients with diabetes. A large sales force may be required to educate and support these physicians. In addition, we cannot commercialize on our own any insulin analog-based formulation in the United States until 2014 at the earliest, when the patents covering the currently marketed insulin analogs first begin to expire. Therefore, our current strategy for developing, manufacturing and commercializing our product candidates includes securing collaborations with leading pharmaceutical and biotechnology companies, including those that hold patents covering the currently marketed insulin analogs. To date, we have not entered into any out-licensing collaborations with pharmaceutical or biotechnology companies. We face significant competition in seeking appropriate collaborators. In addition, collaboration agreements are complex and time-consuming to negotiate, document and implement. For all these reasons, it may be difficult for us to find third parties that are willing to enter into collaborations on economic terms that are favorable to us, or at all. Even if we do enter into any such collaboration, the collaboration may not be successful. The success of our collaboration arrangements will depend heavily on the efforts and activities of our collaborators. It is likely that our collaborators will have significant discretion in determining the efforts and resources that they will apply to these collaborations.

24

If we fail to enter into collaborations, or if our collaborations are unsuccessful, we may be required to establish our own direct sales, marketing, manufacturing and distribution capabilities. Establishing these capabilities can be time-consuming and expensive and we have little experience in doing so. Because of our size, we would be at a disadvantage to our potential competitors to the extent they collaborate with large pharmaceutical companies that have substantially more resources than we do. As a result, we would not initially be able to field a sales force as large as our competitors or provide the same degree of market research or marketing support. In addition, our competitors would have a greater ability to devote research and development resources toward expansion of the indications for their products. We cannot assure our investors that we will succeed in entering into acceptable collaborations, that any such collaboration will be successful or, if not, that we will successfully develop our own sales, marketing and distribution capabilities.

If we are unable to obtain adequate reimbursement from governments or third-party payors for any products that we may develop or if we are unable to obtain acceptable prices for those products, they may not be purchased or used and our revenues and prospects for profitability will suffer.

Our future revenues and profits will depend heavily upon the availability of adequate reimbursement for the use of our approved product candidates from governmental and other third-party payors, both in the United States and in other markets. Reimbursement by a third-party payor may depend upon a number of factors, including the third-party payor's determination that use of a product is:

•a covered benefit under its health plan;

•safe, effective and medically necessary;

•appropriate for the specific patient;

•cost-effective; and

•neither experimental nor investigational.

Obtaining reimbursement approval for a product from each government or other third-party payor is a time-consuming and costly process that could require us to provide supporting scientific, clinical and cost-effectiveness data for the use of our products to each payor. We may not be able to provide data sufficient to gain acceptance with respect to reimbursement. Even when a payor determines that a product is eligible for reimbursement, the payor may impose coverage limitations that preclude payment for some uses that are approved by the FDA or comparable authorities. In addition, eligibility for coverage does not imply that any product will be reimbursed in all cases or at a rate that allows us to make a profit or even cover our costs.

Interim payments for new products, if applicable, may also not be sufficient to cover our costs and may not be made permanent.

Governments outside the United States tend to impose strict price controls, which may adversely affect our revenues, if any.

In some countries, particularly the countries of the European Union, the pricing of prescription pharmaceuticals is subject to governmental control. In these countries, pricing negotiations with governmental authorities can take considerable time after the receipt of marketing approval for a product. To obtain reimbursement or pricing approval in some countries, we may be required to conduct a clinical trial that compares the cost-effectiveness of our product candidate to other available therapies. If reimbursement of our products is unavailable or limited in scope or amount, or if pricing is set at unsatisfactory levels, our business could be adversely affected.

Product liability lawsuits against us could cause us to incur substantial liabilities and to limit commercialization of any products that we may develop.

We face an inherent risk of product liability exposure related to the testing of our product candidates in human clinical trials and will face an even greater risk if we commercially sell any products that we may develop. If we cannot successfully defend ourselves against claims that our product candidates or products caused injuries, we will incur substantial liabilities. Regardless of merit or eventual outcome, liability claims may result in:

•decreased demand for any product candidates or products that we may develop;

25

•injury to our reputation;

•withdrawal of clinical trial participants;

•costs to defend the related litigation;

•substantial monetary awards to trial participants or patients;

•loss of revenue; and

•the inability to commercialize any products that we may develop.

We currently carry global liability insurance that we believe is sufficient to cover us from potential damages arising from past or future clinical trials of our ultra-rapid-acting insulin formulations and other product candidates that we may advance into the clinic. The amount of insurance that we currently hold may not be adequate to cover all liabilities that we may incur. We intend to expand our insurance coverage to include the sale of commercial products if we obtain marketing approval for any products. Insurance coverage is increasingly expensive. We may not be able to maintain insurance coverage at a reasonable cost. If losses from product liability claims exceed our liability insurance coverage, we may ourselves incur substantial liabilities. If we are required to pay a product liability claim, we may not have sufficient financial resources to complete development or commercialization of any of our product candidates and, if so, our business and results of operations would be harmed.

We face substantial competition in the development of our product candidates which may result in others developing or commercializing products before or more successfully than we do.

We are engaged in segments of the pharmaceutical industry that are characterized by intense competition and rapidly evolving technology. Many large pharmaceutical and biotechnology companies, academic institutions, governmental agencies and other public and private research organizations are pursuing the development of novel drugs that target endocrine disorders. We face, and expect to continue to face, intense and increasing competition as new products enter the market and advanced technologies become available. There are several approved injectable rapid-acting mealtime insulin analogs currently on the market including Humalog®, marketed by Eli Lilly and Company, NovoLog®, marketed by Novo Nordisk, and Apidra®, marketed by Sanofi-Aventis. These rapid-acting insulin analogs provide improvement over regular forms of mealtime insulin, including faster subcutaneous absorption, an earlier and greater insulin peak and more rapid post-peak decrease. Both Humalog® and NovoLog® have limited remaining patent protection in the United States and Europe. The possible introduction of lower priced brands or substitutable generic versions of these products could negatively impact the revenue potential of our ultra-rapid-acting product candidates should any be approved.

In addition, other development stage insulin formulations may be approved and compete with ours. Halozyme Therapeutics, Inc. has conducted a Phase 1 and multiple Phase 2 clinical trials of RHI, lispro (the insulin analog in Humalog®) and aspart (the insulin analog in NovoLog®) in combination with a recombinant human hyaluronidase enzyme and has reported that in each case the combination yielded pharmacokinetics and glucodynamics that better mimicked physiologic mealtime insulin release and activity than RHI, Humalog® or NovoLog® alone. Halozyme is currently conducting a clinical trial with approximately 400 patients examining the effects of a preinfusion of hyaluronidase prior to the use of an insulin pump. In 2011, Eli Lilly partnered with a French biotechnology company, Adocia Inc., to develop an insulin analog that would demonstrate a more rapid onset of action. In 2013, Eli Lilly returned all rights to the program to Adocia. Adocia subsequently announced the start of a clinical trial in support of the development of a pre-mixed prandial/basal insulin. Additionally, Novo Nordisk has reported that they have initiated clinical development of an insulin analog intended to provide faster onset of action than the currently available rapid-acting insulin analogs and that a candidate formulation will enter Phase 3 clinical trials in late 2013.

Several companies are also developing alternative insulin systems for diabetes, including MannKind Corporation, which submitted an NDA in early 2009 for an inhalable insulin product candidate. Mannkind's product candidate was not approved by the FDA and MannKind subsequently conducted and completed two additional Phase 3 clinical trials to support a revised NDA. The primary endpoints were met in both trials, and in October 2013 the FDA accepted the resubmission of an NDA for Mannkind's inhaled insulin product candidate. Approval of an inhaled insulin could reduce the overall market for injectable mealtime insulin.

26

A stable glucagon presentation for use as a rescue treatment for diabetes patients experiencing severe hypoglycemia would also face significant competition if it were to be commercialized. Eli Lilly and Novo Nordisk currently market injectable glucagon rescue kit products. We are aware of several glucagon rescue product candidates in early stage development, such as a potentially competitive auto-injector device being developed by Enject Corporation that integrates glucagon powder and a diluent into a dual-chamber cartridge within that device. Xeris Corporation is developing an auto-injector utilizing a concentrated, non-aqueous glucagon formulation, which currently being studied in a clinical trial. In addition, other companies with expertise in protein stabilization, including Latitude Pharmaceuticals, have announced that they have developed a stable glucagon formulation using FDA-approved injectable ingredients. We believe that an intranasal formulation of glucagon is being studied in one or more clinical trials. All of these programs utilize the same active pharmaceutical ingredient as the stable glucagon presentations that we are developing and offer, or may offer, presentations allowing for room temperature storage. In addition, Eli Lilly, Novo Nordisk and Zealand Pharma A/S, a pharmaceutical company based in Denmark, may be developing glucagon analogs, which may also offer advantages over our stable glucagon presentations.

Potential competitors also include academic institutions, government agencies and other public and private research organizations that conduct research, seek patent protection and establish collaborative arrangements for research, development, manufacturing and commercialization. Our competitors may develop products that are more effective, safer, more convenient or less costly than any that we are developing or that would render our product candidates obsolete or non-competitive. Our competitors may also obtain FDA or other regulatory approval for their products more rapidly than we may obtain approval for ours.

Many of our potential competitors have:

•significantly greater financial, technical and human resources than we have and may be better equipped to discover, develop, manufacture and commercialize product candidates;

•more extensive experience in preclinical testing and clinical trials, obtaining regulatory approvals and manufacturing and marketing pharmaceutical products;

•product candidates that have been approved or are in late-stage clinical development; or

•collaborative arrangements in our target markets with leading companies and research institutions.

Our product candidates may be rendered obsolete by technological change.

The rapid rate of scientific discoveries and technological changes could result in one or more of our product candidates becoming obsolete or noncompetitive. For several decades, scientists have attempted to improve the bioavailability of injected formulations and to devise alternative non-invasive delivery systems for the delivery of drugs such as insulin. Our product candidates will compete against many products with similar indications. Our future success will depend not only on our ability to develop our product candidates, but also on our ability to maintain market acceptance against emerging industry developments. We cannot assure current or prospective stockholders that we will be able to do so.

Our business activities involve the storage and use of hazardous materials, which require compliance with environmental and occupational safety laws regulating the use of such materials. If we violate these laws, we could be subject to significant fines, liabilities or other adverse consequences.

Our research and development work and manufacturing processes involve the controlled storage and use of hazardous materials, including chemical and biological materials. Our operations also produce hazardous waste products. We are subject to federal, state and local laws and regulations governing the use, manufacture, storage, handling and disposal of these materials. Although we believe that our safety procedures for handling and disposing of such materials and waste products comply in all material respects with the standards prescribed by federal, state and local laws and regulations, the risk of accidental contamination or injury from hazardous materials cannot be completely eliminated. In the event of an accident or failure to comply with environmental laws, we could be held liable for any damages that may result, and any such liability could fall outside the coverage or exceed the limits of our insurance. In addition, we could be required to incur significant costs to comply with environmental laws and regulations in the future or pay substantial fines or penalties if we violate any of these laws or regulations. Finally, current or future environmental laws and regulations may impair our research, development or production efforts.

27

Risks Related to Our Dependence on Third Parties

Use of third parties to manufacture our product candidates may increase the risks that we will not have sufficient quantities of our product candidates or such quantities at an acceptable cost, or that our contract manufacturers will not be able to manufacture our products in their final dosage form. In any such case, clinical development and commercialization of our product candidates could be delayed, prevented or impaired.

We do not currently own or operate manufacturing facilities for commercial production of our product candidates. We have limited experience in drug manufacturing and we lack the resources and the capabilities to manufacture any of our product candidates on a clinical or commercial scale. Our current strategy is to outsource to third parties all of the manufacturing required for our product candidates, including the dual-chamber reconstitution device for use with our glucagon rescue product candidate. We also expect to rely upon third parties to produce materials required for the commercial production of our product candidates if we succeed in obtaining necessary regulatory approvals.

We have recently relied on the University of Iowa to manufacture our ultra-rapid-acting product candidates, but we do not have any commercial manufacturing agreements in place with third parties to support these product candidates. Reliance on third-party manufacturers entails risks to which we would not be subject if we manufactured product candidates or products ourselves, including:

•reliance on the third party for regulatory compliance and quality assurance;

•the possible breach of the manufacturing agreement by the third party because of factors beyond our control; and

•the possible refusal by or inability of the third party to support our manufacturing programs in a time frame that we would otherwise prefer.

Our manufacturers may not be able to comply with current good manufacturing practice, or cGMP, regulations or other regulatory requirements or similar regulatory requirements outside the United States. Our manufacturers are subject to unannounced inspections by the FDA, state regulators and similar regulators outside the United States. Our failure, or the failure of our third-party manufacturers, to comply with applicable regulations could result in sanctions being imposed on us, including fines, injunctions, civil penalties, failure of regulatory authorities to grant marketing approval of our product candidates, delays, suspension or withdrawal of approvals, license revocation, seizures or recalls of product candidates or products, operating restrictions and criminal prosecutions, any of which could significantly and adversely affect supplies of our product candidates.

Our product candidates and any products that we may develop may compete with other product candidates and products for access to manufacturing facilities. There are a limited number of manufacturers that operate under cGMP regulations and that are both capable of manufacturing for us and willing to do so. If the third parties that we engage to manufacture product for our clinical trials should cease to continue to do so for any reason, we likely would experience delays in advancing these trials while we identify and qualify replacement suppliers and we may be unable to obtain replacement supplies on terms that are favorable to us. In addition, if we are not able to obtain adequate supplies of our product candidates or the drug substances used to manufacture them, it will be more difficult for us to develop our product candidates and compete effectively.

Our current and anticipated future dependence upon others for the manufacture of our product candidates may adversely affect our future profit margins and our ability to develop product candidates and commercialize any products that receive regulatory approval on a timely and competitive basis.

We rely on third parties for design and engineering expertise relating to the development of devices we may use to administer the pharmaceutical preparations of our product candidates.

The success of certain of our product candidates is likely to depend heavily on the design of the devices being used for the administration of our pharmaceutical preparations. For example, while the dual-chamber reconstitution device we intend to use with our leading glucagon rescue product candidate is based on an existing technology platform developed by Unilife Corporation, the device is being customized by Unilife

28

Medical Solutions, Inc., a wholly owned subsidiary of Unilife Corporation, for use in an emergency situation. We do not have internal engineering expertise relating to medical devices, and we therefore rely on Unilife Medical Solutions, Inc. to provide such expertise. If our collaboration with Unilife Medical Solutions, Inc. is not successful in this regard, our program to develop a glucagon rescue product will be materially harmed. Additionally, in order to maximize the commercial potential of our ultra-rapid-acting insulin product candidates, we will likely depend on one or more manufacturers of insulin pen injection devices to supply us with a commercially acceptable device. To date, we have not entered into any agreements for the supply of insulin pen injection devices and we cannot assure you that any such devices will be available on terms that will be acceptable to us, if at all.

We rely on third parties to conduct our clinical trials and those third parties may not perform satisfactorily, including failing to meet established timelines for the completion of such trials.

We do not independently conduct clinical trials of our product candidates. We rely on third parties, such as contract research organizations, clinical data management organizations, medical institutions and clinical investigators, to enroll qualified patients and conduct our clinical trials. Our reliance on these third parties for clinical development activities reduces our control over these activities. We are responsible for ensuring that each of our clinical trials is conducted in accordance with the general investigational plan and protocols for the trial. Moreover, the FDA requires us to comply with standards, commonly referred to as Good Clinical Practices, for conducting, recording, and reporting the results of clinical trials to assure that data and reported results are credible and accurate and that the rights, integrity and confidentiality of trial participants are protected. Our reliance on third parties that we do not control does not relieve us of these responsibilities and requirements. Furthermore, these third parties may also have relationships with other entities, some of which may be our competitors. If these third parties do not successfully carry out their contractual duties, meet expected deadlines or conduct our clinical trials in accordance with regulatory requirements or our stated protocols, we will not be able to obtain, or may be delayed in obtaining, regulatory approvals for our product candidates and will not be able to, or may be delayed in our efforts to, successfully commercialize our product candidates.

If our suppliers of active pharmaceutical ingredients and other production materials fail to deliver materials and provide services needed for the production of our ultra-rapid-acting insulin formulations or our stable glucagon presentations in a timely and sufficient manner, or if they fail to comply with applicable regulations, clinical development or regulatory approval of our product candidates, commercialization of our products could be delayed, producing additional losses and depriving us of potential product revenue.

We need access to sufficient, reliable and affordable supplies of insulin, glucagon and other materials, such as vials, cartridges, prefilled syringes and, potentially, drug injection devices, for which we rely on various suppliers. We also must rely on those suppliers to comply with relevant regulatory and other legal requirements, including the production of insulin and glucagon in accordance with cGMP. We can make no assurances that our suppliers will comply with cGMP.

We have entered into an agreement with our existing RHI supplier from which we obtain all of the RHI that we use for testing and manufacturing our RHI-based formulations. In July 2011, we amended our agreement with this insulin supplier so that the agreement will terminate in June 2018.

We believe that our current supplies of RHI, together with the quantities of RHI called for under our existing supply agreement, will be sufficient to allow us to complete the full development program required by the FDA in order to receive approval to market an RHI-based formulation if we are successful in developing one. If we are unable to procure sufficient quantities of insulin from our current or any future supplier, if supply of RHI and other materials otherwise becomes limited, or if our suppliers do not meet relevant regulatory requirements, and if we were unable to obtain these materials in sufficient amounts, in a timely manner and at reasonable prices, we could be delayed in the manufacturing and possible commercialization of an ultra-rapid-acting insulin, which may have a material adverse effect on our business. We would incur substantial costs and manufacturing delays if our suppliers are unable to provide us with products or services approved by the FDA or other regulatory agencies.

We have entered into a commercial supply agreement with a third party for the supply of glucagon that we intend to use in the manufacture of our glucagon rescue product candidate. However, we have not

29

purchased significant quantities of glucagon from this third-party supplier and we do not anticipate doing so prior to the manufacture of validation batches of a proposed commercial product. Additionally, we have agreed to purchase an excipient used to stabilize one of our glucagon rescue candidate formulations from a third-party that has licensed its proprietary stabilization technologies to us. If this third-party is unable to supply us with sufficient quantities of the stabilizing excipient, our development program for a stable glucagon presentation may be materially harmed.

Apart from our agreement with Unilife Medical Solutions, Inc. for the supply of its dual-chamber reconstitution device, we have not entered into any long-term or exclusive agreements for the supply of one or more insulin analogs or injection devices, some or all of which we would need to procure in significant quantities if we were to commercialize any of our product candidates.

Risks Related to Our Intellectual Property

If we are unable to protect our intellectual property rights, our competitors may develop and market similar or identical products that may reduce demand for our products, and we may be prevented from establishing collaborative relationships on favorable terms.

The following factors are important to our success:

•receiving patent protection for our product candidates;

•maintaining our trade secrets;

•not infringing on the proprietary rights of others; and

•preventing others from infringing on our proprietary rights.

We will be able to protect our proprietary rights from unauthorized use by third parties only to the extent that our proprietary rights are covered by valid and enforceable patents or are effectively maintained as trade secrets. We try to protect our proprietary position by filing U.S. and foreign patent applications related to our proprietary technology, inventions and improvements that are important to the development of our business. Because the patent position of pharmaceutical companies involves complex legal and factual questions, the issuance, scope and enforceability of patents cannot be predicted with certainty. Patents, if issued, may be challenged, invalidated or circumvented. Thus, any patents that we own or license from others may not provide any protection against competitors.

In June 2012, we entered into an agreement with Aegis Therapeutics, LLC, or Aegis, to acquire an exclusive, sub-licensable, worldwide license to the protein stabilization technology that we are using in the development of our stable liquid glucagon formulations. Under the terms of the agreement, Aegis will prepare, file, prosecute and maintain patents and patent applications that are specific to our stable glucagon presentations in jurisdictions that we may designate from time to time.

In April 2013, we entered into a customization and commercial supply agreement with Unilife Medical Solutions, Inc., a wholly owned subsidiary of Unilife Corporation, to acquire an exclusive, sub-licensable, worldwide license to a proprietary device platform of dual-chamber devices for use with glucagon. Under the terms of the agreement, Unilife Medical Solutions, Inc. will be the sole owner of improvements to the dual-chamber devices developed under the agreement and any attendant intellectual property rights.

Our pending patent applications, those we may file in the future, or those we may license from third parties, may not result in patents being issued. If patents do not issue with claims encompassing our products, our competitors may develop and market similar or identical products that compete with ours. Even if patents are issued, they may not provide us with proprietary protection or competitive advantages against competitors with similar technology. Failure to obtain effective patent protection for our technology and products may reduce demand for our products and prevent us from establishing collaborative relationships on favorable terms.

The individual active and inactive ingredients in our ultra-rapid-acting insulin formulations and our stable glucagon presentations have been known and used for many years and, therefore, are no longer subject to patent protection, except in proprietary combinations. Accordingly, our patent and pending applications are directed to the particular formulations of these ingredients in our products, and to their use. Although we

30

believe our formulations and their uses are or will be patented and provide a competitive advantage, our patents may not prevent others from marketing formulations using the same active and inactive ingredients in different combinations.

The individual active and inactive ingredients in our dual-chamber glucagon rescue product candidate have been known and used for many years and, therefore, are no longer subject to patent protection. As a result, the commercial success of this product candidate, if approved, will depend heavily on the patent protection afforded to the device developed and controlled by Unilife Medical Solutions, Inc.

We also rely on trade secrets, know-how and technology, which are not protected by patents, to maintain our competitive position. We try to protect this information by entering into confidentiality agreements with parties that have access to it, such as potential corporate partners, collaborators, employees and consultants. Any of these parties may breach the agreements and disclose our confidential information or our competitors may learn of the information in some other way. Furthermore, others may independently develop similar technologies or duplicate any technology that we have developed. If any trade secret, know-how or other technology not protected by a patent were to be disclosed to or independently developed by a competitor, our business and financial condition could be materially adversely affected.

The laws of many foreign countries do not protect intellectual property rights to the same extent as do the laws of the United States. Accordingly, the fact that we have obtained certain patent rights in the United States does not guarantee that we will be able to obtain the same or similar rights elsewhere. Even if we are granted patents in foreign countries, we cannot guarantee that we will be able to enforce our rights effectively.

We may become involved in lawsuits and administrative proceedings to protect, defend or enforce our patents that would be expensive and time-consuming.

In order to protect or enforce our patent rights, we may initiate patent litigation against third parties in the United States or in foreign countries. In addition, we may be subject to certain opposition proceedings conducted in patent and trademark offices challenging the validity of our patents and may become involved in future opposition proceedings challenging the patents of others. For example, in late July 2013, a third party initiated administrative proceedings to oppose two of our more recent patents that have been granted by the European Patent Office in connection with our ultra-rapid-acting insulin formulations. While an earlier issued European patent covers technologies fundamental to our ultra-rapid-acting insulin formulations, the more recent patents may offer additional protections against potential competitors. The defense of intellectual property rights, including patent rights, through lawsuits, interference or opposition proceedings, and other legal and administrative proceedings can be costly and can divert our technical and management personnel from their normal responsibilities. Such costs increase our operating losses and reduce our resources available for development activities. An adverse determination of any litigation or defense proceedings could put one or more of our patents at risk of being invalidated or interpreted narrowly and could put our patent applications at risk of not issuing.

Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk that some of our confidential information could be compromised by disclosure during this type of litigation. For example, during the course of this kind of litigation and despite protective orders entered by the court, confidential information may be inadvertently disclosed in the form of documents or testimony in connection with discovery requests, depositions or trial testimony. This disclosure could materially adversely affect our business and financial results.

Claims by other parties that we infringe or have misappropriated their proprietary technology may result in liability for damages, royalties, or other payments, or stop our development and commercialization efforts.

Competitors and other third parties may initiate patent litigation against us in the United States or in foreign countries based on existing patents or patents that may be granted in the future. Many of our competitors may have obtained patents covering products and processes generally related to our products and processes, and they may assert these patents against us. Moreover, there can be no assurance that these competitors have not sought or will not seek additional patents that may cover aspects of our technology. As a result, there is a greater likelihood of a patent dispute than would be expected if our competitors were pursuing unrelated technologies.

31

While we conduct patent searches to determine whether the technologies used in our products infringe patents held by third parties, numerous patent applications are currently pending and may be filed in the future for technologies generally related to our technologies, including many patent applications that remain confidential after filing. Due to these factors and the inherent uncertainty in conducting patent searches, there can be no guarantee that we will not violate third-party patent rights that we have not yet identified.

There may be U.S. and foreign patents issued to third parties that relate to aspects of our product candidates. There may also be patent applications filed by these or other parties in the United States and various foreign jurisdictions that relate to some aspects of our product candidates, which, if issued, could subject us to infringement actions. The owners or licensees of these and other patents may file one or more infringement actions against us. In addition, a competitor may claim misappropriation of a trade secret by an employee hired from that competitor. Any such infringement or misappropriation action could cause us to incur substantial costs defending the lawsuit and could distract our management from our business, even if the allegations of infringement or misappropriation are unwarranted. A need to defend multiple actions or claims could have a disproportionately greater impact. In addition, either in response to or in anticipation of any such infringement or misappropriation claim, we may enter into commercial agreements with the owners or licensees of these rights. The terms of these commercial agreements may include substantial payments, including substantial royalty payments on revenues received by us in connection with the commercialization of our products.

Payments under such agreements could increase our operating losses and reduce our resources available for development activities. Furthermore, a party making this type of claim could secure a judgment that requires us to pay substantial damages, which would increase our operating losses and reduce our resources available for development activities. A judgment could also include an injunction or other court order that could prevent us from making, using, selling, offering for sale or importing our products or prevent our customers from using our products. If a court determined or if we independently concluded that any of our products or manufacturing processes violated third-party proprietary rights, our clinical trials could be delayed and there can be no assurance that we would be able to reengineer the product or processes to avoid those rights, or to obtain a license under those rights on commercially reasonable terms, if at all.

Risks Related to Regulatory Approval of Our Product Candidates

If the FDA does not believe that our product candidates satisfy the requirements for the Section 505(b)(2) approval procedure, or if the requirements for our product candidates under Section 505(b)(2) are not as we expect, the approval pathway will take longer and cost more than anticipated and in either case may not be successful.

We believe our ultra-rapid-acting insulin formulations and our stable glucagon presentation for use as a rescue product qualify for approval under Section 505(b)(2) of the FFDCA. Because we are developing new formulations of previously approved chemical entities, such as insulin and glucagon, our drug approval strategy is to submit Section 505(b)(2) NDAs to the FDA. We plan to pursue similar routes for submitting applications for our product candidates in foreign jurisdictions if available. The FDA may not agree that our product candidates are approvable pursuant to Section 505(b)(2) NDAs. There is no specific guidance available for Section 505(b)(2) NDAs for insulin or glucagon. In addition, while there is precedent for a glucagon product being approved under a Section 505(b)(2) NDA, we are not aware of any insulin product that has been approved under a Section 505(b)(2) NDA. If the FDA determines that Section 505(b)(2) NDAs are not appropriate and that full NDAs are required for our product candidates, the time and financial resources required to obtain FDA approval for our product candidates could substantially and materially increase, and our product candidates might be less likely to be approved. If the FDA requires full NDAs for our product candidates, or requires more extensive testing and development for some other reason, our ability to compete with alternative products that arrive on the market more quickly than our product candidates would be adversely impacted.

Notwithstanding the approval of many products by the FDA pursuant to Section 505(b)(2), over the last few years certain pharmaceutical companies and others have objected to the FDA's interpretation of Section 505(b)(2). If the FDA's interpretation of Section 505(b)(2) is successfully challenged in court, the FDA may be required to change its interpretation of Section 505(b)(2) which could delay or even prevent the FDA from

32

approving any Section 505(b)(2) NDA that we submit. The pharmaceutical industry is highly competitive, and it is not uncommon for a manufacturer of an approved product to file a citizen petition with the FDA seeking to delay approval of, or impose additional approval requirements for, pending competing products. If successful, such petitions can significantly delay, or even prevent, the approval of the new product. Moreover, even if the FDA ultimately denies such a petition, the FDA may substantially delay approval while it considers and responds to the petition.

Even if one of our product candidates is approved under Section 505(b)(2), the approval may be subject to limitations on the indicated uses for which the product may be marketed or to other conditions of approval, or may contain requirements for costly post-marketing testing and surveillance to monitor the safety or efficacy of the product.

Any product for which we obtain marketing approval could be subject to restrictions or withdrawal from the market and we may be subject to penalties if we fail to comply with regulatory requirements or if we experience unanticipated problems with our products, when and if any of them are approved.

Any product for which we obtain marketing approval, along with the manufacturing processes, post-approval clinical data, labeling, advertising and promotional activities for such product, will be subject to continual requirements of and review by the FDA and other state and federal regulatory authorities. These requirements include, in the case of the FDA, submissions of safety and other post-marketing information and reports, registration requirements, cGMP requirements relating to quality control, quality assurance and corresponding maintenance of records and documents, requirements regarding the distribution of samples to physicians and recordkeeping. Even if regulatory approval of a product is granted, the approval may be subject to limitations on the indicated uses for which the product may be marketed or to other conditions of approval, or may contain requirements for costly post-marketing testing and surveillance to monitor the safety or efficacy of the product. In addition, if any of our product candidates are approved, our product labeling, advertising and promotion would be subject to regulatory requirements and continuing regulatory review. The FDA strictly regulates the promotional claims that may be made about prescription drug products. In particular, a drug may not be promoted in a misleading manner or for uses that are not approved by the FDA as reflected in the product's approved labeling. The FDA and other state and federal entities actively enforce the laws and regulations prohibiting misleading promotion and the promotion of off-label uses, and a company that is found to have improperly promoted off-label uses may be subject to significant liability.

Discovery after approval of previously unknown problems with our products, manufacturers or manufacturing processes, or failure to comply with state or federal regulatory requirements, may result in actions such as:

•restrictions on such products' manufacturers or manufacturing processes;

•restrictions on the marketing or distribution of a product;

•requirements that we conduct new studies, make labeling changes, and implement Risk Evaluation and Mitigation Strategies;

•warning letters;

•withdrawal of the products from the market;

•refusal to approve pending applications or supplements to approved applications that we submit;

•recall of products;

•fines, restitution or disgorgement of profits or revenue;

•suspension or withdrawal of regulatory approvals;

•refusal to permit the import or export of our products;

•product embargo and/or seizure;

•injunctions; or

•imposition of civil or criminal penalties.

33

Changes in law, regulations, and policies may preclude approval of our product under a 505(b)(2) or make it more difficult and costly for us to obtain regulatory approval of our product candidates and to produce, market and distribute our existing products.

In March 2010, the President signed into law legislation creating an abbreviated pathway for approval under the Public Health Service, or PHS Act, of biological products that are similar to other biological products that are approved under the PHS Act. This legislation also expanded the definition of biological product to include proteins such as insulin. The new law contains transitional provisions governing protein products such as insulin that, under certain circumstances, might permit companies to seek approval for their insulin products as biologics under the PHS Act and might require that Biodel's product be approved under the PHS Act rather than in a 505(b)(2) NDA. We would be unlikely to pursue approval of our RHI- or insulin analog-based product candidates if we were required to seek approval under the PHS Act rather than in a 505(b)(2) NDA.

In addition, the federal and state laws, regulations, policies or guidance may change in a manner that could prevent or delay regulatory approval of our product candidates or further restrict or regulate post-approval activities. It is impossible to predict whether additional legislative changes will be enacted, or FDA regulations, guidance or interpretations implemented or modified, or what the impact of such changes, if any, may be.

Failure to obtain regulatory approval in international jurisdictions would prevent us from marketing our products abroad.

We intend to have our products marketed outside the United States. In order to market our products in the European Union and many other jurisdictions, we must obtain separate regulatory approvals and comply with numerous and varying regulatory requirements of other countries regarding safety and efficacy and governing, among other things, clinical trials and commercial sales and distribution of our products. The approval procedure varies among countries and can involve additional testing. The time required to obtain approval may differ from that required to obtain FDA approval. The regulatory approval processes outside the United States may include all of the risks associated with obtaining FDA approval, as well as additional risks. In addition, in many countries outside the United States, it is required that the product be approved for reimbursement before the product can be approved for sale in that country. We may not obtain approvals from regulatory authorities outside the United States on a timely basis, if at all. Approval by the FDA does not ensure approval by regulatory authorities in other countries or jurisdictions, and approval by one regulatory authority outside the United States does not ensure approval by regulatory authorities in other countries or jurisdictions or by the FDA. We may not be able to file for regulatory approvals and may not receive necessary approvals to commercialize our products in any market.

Reports of side effects or safety concerns in related technology fields or in other companies' clinical trials could delay or prevent us from obtaining regulatory approval or negatively impact public perception of our product candidates.

At present, there are a number of clinical trials being conducted by us and by other pharmaceutical companies involving insulin or insulin delivery systems. The major safety concern with patients taking insulin is the occurrence of hypoglycemic events. If we discover that our product is associated with a significantly increased frequency of hypoglycemic or other adverse events, or if other pharmaceutical companies announce that they observed frequent or significant adverse events in their trials involving insulin or insulin delivery systems, we could encounter delays in the commencement or completion of our clinical trials or difficulties in obtaining the approval of our product candidates. In addition, the public perception of our products might be adversely affected, which could harm our business and results of operations, even if the concern relates to another company's product.

Risks Related to Employee Matters and Managing Growth

Our future success depends on our ability to retain our chief executive officer and other key executives and to attract, retain and motivate qualified personnel.

We are highly dependent on Errol De Souza, our President and Chief Executive Officer, Gerard Michel, our Chief Financial Officer and Dr. Alan Krasner, our Chief Medical Officer. The loss of the services of any

34

of these persons might impede the achievement of our research, development and commercialization objectives. Replacing key employees may be difficult and time-consuming because of the limited number of individuals in our industry with the skills and experiences required to develop, gain regulatory approval of and commercialize our product candidates successfully. We generally do not maintain key person life insurance to cover the loss of any of our employees.

Recruiting and retaining qualified scientific personnel, clinical personnel and sales and marketing personnel will also be critical to our success. We may not be able to attract and retain these personnel on acceptable terms, if at all, given the competition among numerous pharmaceutical and biotechnology companies for similar personnel. We also experience competition for the hiring of scientific and clinical personnel from other companies, universities and research institutions. In addition, we rely on consultants and advisors, including scientific and clinical advisors, to assist us in formulating our research and development and commercialization strategy. Our consultants and advisors may be employed by employers other than us and may have commitments under consulting or advisory contracts with other entities that may limit their availability to us.

We may expand our development, regulatory and sales and marketing capabilities, and as a result, we may encounter difficulties in managing our growth, which could disrupt our operations.

If our development and commercialization plans for any of our product candidates are successful, we may experience significant growth in the number of our employees and the scope of our operations, particularly in the areas of manufacturing, clinical trials management, and regulatory affairs. To manage our anticipated future growth, we must continue to implement and improve our managerial, operational and financial systems and continue to recruit and train additional qualified personnel. Due to our limited financial resources we may not be able to effectively manage the expansion of our operations or recruit and train additional qualified personnel. Any inability to manage growth could delay the execution of our business plans or disrupt our operations.

Risks Related to Our Common Stock

Provisions in our corporate charter documents and under Delaware law could make an acquisition of us, which may be beneficial to our stockholders, more difficult and may prevent attempts by our stockholders to replace or remove our current management.

Provisions in our corporate charter and bylaws may discourage, delay or prevent a merger, acquisition or other change in control of us that stockholders may consider favorable, including transactions in which you might otherwise receive a premium for your shares. These provisions could also limit the price that investors might be willing to pay in the future for shares of our common stock, thereby depressing the market price of our common stock. In addition, these provisions may frustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace members of our board of directors. Because our board of directors is responsible for appointing the members of our management team, these provisions could in turn affect any attempt by our stockholders to replace current members of our management team.

Among others, these provisions:

•establish a classified board of directors such that not all members of the board are elected at one time;

•allow the authorized number of our directors to be changed only by resolution of our board of directors;

•limit the manner in which stockholders can remove directors from the board;

•establish advance notice requirements for stockholder proposals that can be acted on at stockholder meetings and nominations to our board of directors;

•require that stockholder actions must be effected at a duly called stockholder meeting and prohibit actions by our stockholders by written consent;

•limit who may call stockholder meetings;

35

•authorize our board of directors to issue preferred stock without stockholder approval, which could be used to institute a stockholder rights plan or "poison pill" that would work to dilute the stock ownership of a potential hostile acquirer, effectively preventing acquisitions that have not been approved by our board of directors; and

•require the approval of the holders of at least 75% of the votes that all our stockholders would be entitled to cast to amend or repeal certain provisions of our charter or bylaws.

In addition, because we are incorporated in Delaware, we are governed by the provisions of Section 203 of the Delaware General Corporation Law, which generally prohibits a person who owns in excess of 15% of our outstanding voting stock from merging or combining with us for a period of three years after the date of the transaction in which the person acquired in excess of 15% of our outstanding voting stock, unless the merger or combination is approved in a prescribed manner.

If our stock price is volatile, purchasers of our common stock could incur substantial losses.

Our stock price has been and may continue to be volatile. The stock market in general and the market for biotechnology companies in particular have experienced extreme volatility that has often been unrelated to the operating performance of particular companies. The market price for our common stock may be influenced by many factors, including:

•results of clinical trials of our product candidates or those of our competitors;

•regulatory or legal developments in the United States and other countries;

•variations in our financial results or those of companies that are perceived to be similar to us;

•developments or disputes concerning patents or other proprietary rights;

•the recruitment or departure of key personnel;

•changes in the structure of healthcare payment systems;

•market conditions in the pharmaceutical and biotechnology sectors and issuance of new or changed securities analysts' reports or recommendations;

•general economic, industry and market conditions; and

•the other factors described in this "Risk Factors" section.

Our outstanding warrants may be exercised, and our outstanding shares of preferred stock may be converted, in the future, which would increase the number of shares in the public market and result in dilution to our stockholders.

As a result of our May 2011 registered direct offering and June 2012 private placement, we have outstanding warrants to purchase 2,256,929 shares of our common stock at $9.92 per share and 2,749,469 shares of our common stock at $2.66 per share. The $9.92 per share warrants expire in May 2016 and the $2.66 per share warrants expire in June 2017. We also have outstanding shares of Series B preferred stock that are convertible into 1,950,000 shares of common stock. In June and September 2013 an aggregate of 1,655,607 shares of Series B preferred stock were converted into an equal number of shares of common stock. The exercise of these warrants for, or the conversion of shares of Series B preferred stock into, shares of common stock would be substantially dilutive to the outstanding shares of common stock. Any dilution or potential dilution may cause our stockholders to sell their shares, which would contribute to a downward movement in the stock price of our common stock.

We have never paid any cash dividends on our capital stock and we do not anticipate paying any cash dividends in the foreseeable future.

We have paid no cash dividends on our capital stock to date. We currently intend to retain our future earnings, if any, to fund the development and growth of our business. In addition, the terms of any future debt agreements may preclude us from paying dividends. As a result, we do not expect to pay any cash dividends in the foreseeable future, and payment of cash dividends, if any, will depend on our financial condition, results of operations, capital requirements and other factors and will be at the discretion of our board of directors.

36

Furthermore, we may in the future become subject to contractual restrictions on, or prohibitions against, the payment of dividends. Capital appreciation, if any, of our common stock will be investors' sole source of gain for the foreseeable future.

We incur substantial costs as a result of operating as a public company, and our management is required to devote substantial time to comply with public company regulations.

We are subject to the reporting requirements of the Exchange Act, the Sarbanes-Oxley Act of 2002 as well as other federal and state laws. These requirements may place a strain on our people, systems and resources. The Exchange Act requires that we file annual, quarterly and current reports with respect to our business and financial condition. The Sarbanes-Oxley Act requires that we maintain effective disclosure controls and procedures and internal controls over financial reporting. In order to maintain and improve the effectiveness of our disclosure controls and procedures and internal controls over financial reporting, significant resources and management oversight will be required. This may divert management's attention from other business concerns, which could have a material adverse effect on our business, financial condition, results of operations and cash flows.

Risks Related to our June 2012 Private Placement

The number of shares of our common stock outstanding has increased substantially as a result of our June 2012 private placement, and some of the purchasers in the private placement beneficially own significant blocks of our common stock; the securities that we issued in the private placement will be generally available for resale in the public market upon registration under the Securities Act of 1933, as amended, or the Securities Act.

In June 2012, we completed our 2012 private placement of an aggregate of 4,250,020 shares of our common stock, 3,605,607 shares of our Series B preferred stock and warrants to purchase an aggregate of 2,749,469 shares of our common stock. The issuance of these shares and warrants resulted in substantial dilution to stockholders who held our common stock prior to the 2012 private placement. Some of the purchasers in the private placement will have significant influence over the outcome of any stockholder vote, including the election of directors and the approval of mergers or other business combination transactions.

Pursuant to the securities purchase agreement that we entered into with the purchasers in the 2012 private placement, we filed with the Securities and Exchange, or the SEC, a registration statement to register the resale of the shares of common stock and Series B preferred stock issued and sold in the private placement, the shares of common stock issuable upon conversion of the Series B preferred stock issued and sold in the private placement, and the shares of common stock issuable upon exercise of the warrants issued and sold in the private placement. Upon the effectiveness of the registration statement, these securities became generally available for resale in the public market. The market price of our common stock could fall as a result of an increase in the number of shares available for sale in the public market.

If we do not maintain effectiveness of the registration statement, we will be required to pay certain liquidated damages, which could be material in amount.

Pursuant to the terms of the securities purchase agreement that we entered into with the purchasers in the 2012 private placement, we have agreed to pay liquidated damages to such purchasers if the registration statement we filed with the SEC, which was declared effective on August 13, 2012, is suspended or ceases to remain continuously effective as to all the securities for which it is required to be effective. We refer to such an event as a registration default. Subject to the specified exceptions, for each 30-day period or portion thereof during which a registration default remains uncured, we are obligated to pay liquidated damages to each purchaser in cash in an amount equal to 1% of the aggregate purchase price paid by each such purchaser in the private placement, up to a maximum of 8% of such aggregate purchase price. These amounts could be material, and any liquidated damages we are required to pay could have a material adverse effect on our financial condition.

ITEM 7.  MANAGEMENT DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

You should read the following discussion and analysis of our financial condition and results of operations together with our financial statements and the related notes included elsewhere in this Annual Report on Form 10-K. Some of the information contained in this discussion and analysis or set forth elsewhere in this Form 10-K, including information with respect to our plans and strategy for our business and related financing, includes forward-looking statements that involve risks and uncertainties. You should read the "Risk Factors" section of this Form 10-K (see Part I-Item 1A above) for a discussion of important factors that could cause actual results to differ materially from the results described in or implied by the forward-looking statements contained in the following discussion and analysis.

Overview

We are a specialty biopharmaceutical company focused on the development and commercialization of innovative treatments for diabetes that may be safer, more effective and more convenient for patients. We develop our product candidates by applying our proprietary formulation technologies to existing drugs in order to improve their therapeutic profiles. Our proprietary insulin formulations are designed to be more rapid-acting than the formulations currently available to Type 1 and Type 2 diabetes patients. We refer to these as "ultra-rapid-acting" formulations. Our glucagon formulations and presentations are designed to be stable at room temperature and are intended for use by caregivers with no medical training as a rescue treatment for diabetes patients experiencing severe hypoglycemia, or very low concentrations of blood glucose.

Our most advanced ultra-rapid-acting insulin formulation, BIOD-123, combines recombinant human insulin, or RHI, with our proprietary combination of excipients to increase the rate of absorption following injection when compared to other commercially available insulin formulations, including "rapid-acting" mealtime insulin analogs such as Humalog®, marketed by Eli Lilly, Novolog®, marketed by Novo Nordisk and Apidra®, marketed by Sanofi-Aventis. We are also using our proprietary excipients to develop ultra-rapid-acting insulin analog-based formulations using either insulin lispro, the active pharmaceutical ingredient in Humalog®, or insulin aspart, the active pharmaceutical ingredient in NovoLog®.

An earlier RHI-based formulation known as Linjeta™ (and previously referred to as VIAject®) was the subject of a New Drug Application, or NDA, that we submitted to the FDA in December 2009. In October 2010, the FDA issued a complete response letter stating that the NDA for Linjeta™ could not be approved in its submitted form and that we should conduct two new Phase 3 clinical trials using our preferred commercial formulation of Linjeta™ prior to re-submitting the NDA. Based upon the complete response letter and subsequent feedback that the FDA provided, we decided to develop newer RHI-based formulations with the goal of identifying a formulation with a pharmacokinetic and pharmacodynamic profile similar to Linjeta™, but with improved injection site toleration characteristics. From January 2011 to April 2012, we studied several such newer formulations, including BIOD-123, in Phase 1 clinical trials. In these trials, we used Humalog® as the comparator drug rather than the comparator drug we used in our Phase 3 Linjeta™ clinical trials. In our Phase 3 clinical trials, the comparator drug was Humulin® R, an RHI-based insulin formulation marketed by Eli Lilly that is less rapid-acting than the insulin analog Humalog®.

BIOD-123 achieved our target pharmacokinetic, pharmacodynamic and injection site toleration profiles for a candidate RHI-based formulation in a Phase 1 clinical trial completed in April 2012, and in the third calendar quarter of 2012 we began enrolling patients in a Phase 2 clinical trial of BIOD-123. The Phase 2 clinical trial of BIOD-123 was a randomized, open label, parallel group study conducted at 32 investigative centers in the United States. In the trial, 132 patients with Type 1 diabetes were randomized to receive either BIOD-123 or Humalog® to use as their mealtime insulin during an 18-week treatment period. Both arms of the study used insulin glargine, sold as Lantus®, as the basal insulin. The clinical trial was designed to evaluate HbA1c control as the primary endpoint, and secondary endpoints included postprandial glucose excursions, glycemic variability, hypoglycemic event rates and weight changes.

The Phase 2 clinical trial of BIOD-123 completed patient dosing in the second calendar quarter of 2013, and in September 2013 we announced preliminary results from the trial. BIOD-123 achieved the primary endpoint of noninferiority for HbA1c relative to Humalog®. The mean HbA1c change from baseline in the BIOD-123 group was -0.08 ± 0.064% and -0.25± 0.063% in the Humalog® group. The 95% confidence

42

interval (-0.01, 0.35) of the between group differences in change from baseline HbA1c did not exceed the FDA-designated threshold of 0.40%, thereby establishing non-inferiority. We expect to provide an update on our further development plans for BIOD-123 after completing our analysis of the data from the Phase 2 clinical trial and following discussions with FDA on clinical trial design, safety and chemistry, manufacturing and controls relating to potential future studies.

In addition to BIOD-123, we have other RHI-based formulations in earlier stages of development. In particular, we are developing ultra-rapid-acting formulations of concentrated insulin that are characterized by a rapid onset of action and a prolonged duration of action. We believe these formulations could address an unmet medical need for an insulin with an initial rate of absorption superior to that of existing concentrated insulins and prandial/basal pre-mixed insulins. In November 2013, we announced that we had initiated a Phase 1 clinical trial with BIOD-531, our lead candidate for an ultra-rapid-acting concentrated insulin formulation. BIOD-531 contains 400 units of RHI per milliliter (instead of the standard 100 units per milliliter), and is formulated with EDTA, citrate and magnesium sulfate. In preclinical studies in diabetic swine, BIOD-531 demonstrated a more rapid rate of absorption and onset of action, along with a similar duration of action, when compared to Humulin® R U-500, a presentation containing 500 units of RHI per millimeter. In other preclinical studies, BIOD-531 also demonstrated a more rapid rate of absorption and onset of action when compared to Humalog® pre-mixed prandial/basal formulations. In the Phase 1 clinical trial of BIOD-531, we will evaluate and compare the onset and duration of action and injection site tolerability of BIOD-531 to Humulin® R U-500 and to Humalog® prandial/basal pre-mixed insulin. We anticipate reporting top line data from the clinical trial in the first calendar quarter of 2014.

We also continue to develop ultra-rapid-acting insulin analog-based formulations. In January 2013, we announced top-line results from our Phase 1 clinical trial of two insulin analog-based formulations, BIOD-238 and BIOD-250. These formulations, which were manufactured using commercial preparations of Humalog®, generally use the same or similar excipients as BIOD-123 and were intended to be optimized for rapid absorption and injection site toleration. The trial, which was conducted in Australia, was designed to compare the pharmacokinetic and injection site toleration profiles of BIOD-238 and BIOD-250 relative to Humalog®. In the trial, both formulations met our target pharmacokinetic profile for an ultra-rapid-acting insulin analog-based formulation, and BIOD-250 met our target injection site toleration profile. We do not expect to study these formulations in additional clinical trials because they were formulated by adding our proprietary excipients to the marketed formulation of Humalog® and because they do not demonstrate stability characteristics consistent with our target product profile. Accordingly, we are continuing our insulin analog-based formulation work to develop formulations using insulin lispro as the active pharmaceutical ingredient, rather than a marketed presentation of Humalog®.

In addition to our ultra-rapid-acting insulin formulation program, we are developing room temperature stable glucagon presentations for use as a rescue treatment for diabetes patients experiencing severe hypoglycemia. In June 2013, we announced plans to develop a novel glucagon rescue product to treat severe hypoglycemia using a proprietary device from Unilife Corporation. The device, which is being customized for use in emergency situations by patient caregivers with no medical training, is a dual-chamber design that automatically reconstitutes lyophilized glucagon with a liquid diluent immediately prior to injection, and it features automatic needle retraction on full dose delivery. We expect to submit an Investigational New Drug application to the FDA for our dual-chamber glucagon rescue product during the next nine months and anticipate conducting a pivotal clinical trial in the second half of 2014. We are also conducting preclinical testing to develop liquid formulations of glucagon for hypoglycemic rescue and other indications.

We are a development stage company. We were incorporated in December 2003 and commenced active operations in January 2004. To date, we have generated no revenues and have incurred significant losses. We expect to continue to incur operating losses as we continue our efforts to develop and commercialize our product candidates. We have financed our operations and internal growth through various financing transactions, including our initial public offering in May 2007 and several subsequent transactions, including, most recently, our June 2013 public offering. We have devoted substantially all of our efforts to research and development activities, including clinical trials. Our net loss was $19.3 million for the year ended September 30, 2013. As of September 30, 2013, we had a deficit accumulated during the development stage of $215.4 million. Research and development and general and administrative expenses, as a percentage of net loss applicable to common stockholders, represent approximately 74% and 35%, respectively, of the expenses that we have incurred since our inception.

43

As of September 30, 2013, we had approximately $39.8 million in cash and cash equivalents compared to $39.1 million in cash and cash equivalents as of September 30, 2012. We believe that our existing cash, cash equivalents and restricted cash will be sufficient to fund our anticipated operating expenses and capital expenditures at least until the second calendar quarter of 2015. We believe that future cash expenditures will be partially offset by raising additional capital from research grants, capital markets, proceeds derived from collaborations, including, but not limited to, upfront fees, research and development funding, milestone payments and royalties. We can give no assurances that such funding will, in fact, be realized in the time frames we expect, or at all. We may be required to secure alternative financing arrangements or defer or limit some or all of our research, development or clinical projects.

Financial Operations Overview

Revenues

To date, we have generated no revenues. We do not expect to begin generating any revenues unless any of our product candidates receive marketing approval, or if we receive payments in connection with strategic collaborations that we may enter into for the commercialization of our product candidates.

Research and Development Expenses

Research and development expenses consist of the costs associated with our basic research activities, as well as the costs associated with our drug development efforts, conducting preclinical studies and clinical trials, manufacturing development efforts and activities related to regulatory filings. Our research and development expenses consist of:

•external research and development expenses incurred under agreements with third-party contract research organizations and investigative sites, third-party manufacturing organizations and consultants;

•employee-related expenses, which include salaries and benefits for the personnel involved in our preclinical and clinical drug development and manufacturing activities; and

•facilities, depreciation and other allocated expenses, which include direct and allocated expenses for rent and maintenance of facilities, depreciation of leasehold improvements and equipment and laboratory and other supplies.

We intend to focus our research and development efforts on conducting preclinical studies and Phase 1 and Phase 2 clinical trials to determine our preferred development, clinical and regulatory program for our ultra-rapid-acting insulin formulations and our stable glucagon presentations. We also expect to conduct a pivotal clinical trial in support of an NDA for our dual-chamber glucagon rescue product candidate. We anticipate that our research and development expenses for the fiscal year ending September 30, 2014 will increase as compared to the fiscal year ended September 30, 2013, as we continue to:

•conduct the development work necessary to finalize the formulation and design of our dual-chamber glucagon rescue product candidate, as well as the preclinical studies, clinical trials and manufacturing activities necessary to support the filing of an NDA to the FDA for that product candidate;

•conduct additional formulation development work to improve the stability, pharmacokinetic, and pharmacodynamic properties of our ultra-rapid-acting insulin analog-based formulations, our concentrated insulin formulations and our liquid glucagon formulations, or purchase rights related to proprietary technologies that are compatible with our product candidates;

•purchase active pharmaceutical ingredients and other materials to support our research and development activities.

Over the longer term, we anticipate that these expenses will increase further as we:

•conduct later stage clinical trials of our ultra-rapid-acting insulin formulations and our dual-chamber glucagon rescue product, including one or more pivotal clinical trials required for FDA approval of NDAs for these product candidates; and

•Prepare and file an NDA for our dual-chamber glucagon rescue product candidate.

We have used our employee and infrastructure resources across multiple research projects and our drug development programs for our ultra-rapid-acting insulin formulations, including BIOD-123, BIOD-238 and BIOD-250, our concentrated insulin formulations and our stable glucagon presentations. Substantially all of our research and development expenses incurred to date are attributable to our ultra-rapid-acting insulin program.

In July and September 2012, we were awarded two National Institutes of Health grants for the development of a concentrated ultra-rapid-acting insulin formulation and a stable glucagon formulation, respectively, for use in an artificial pancreas. The July 2012 award is intended to fund research to develop a proprietary ultra-rapid-insulin product candidate at high concentrations suited to provide sufficient quantities of insulin in an external artificial pancreas pump device that has limited volume capacity. The July 2012 award is for two years and totals $582 thousand. The September 2012 award is intended to fund research to develop a proprietary glucagon product candidate optimized to algorithmically deliver glucagon as part of a bi-hormonal closed loop system to mitigate hypoglycemic events. The September 2012 award is for two years and totals $583 thousand.

The following table illustrates, for each period presented, our research and development costs by nature of the cost.

		Year Ended September 30,						December 3, 2003 (Inception) to September 30, 2013
		2011		2012		2013

The following table illustrates, for each period presented, our research and development costs by project. The year ended September 30, 2011 and inception to date are not noted because we did not track expenses by project in prior years, and therefore cannot accurately reflect past expense history by project.

Other		3,794		4,183
Total	$	12,315	$	14,296

The successful development of our product candidates is highly uncertain. At this time, we cannot reasonably estimate or know the nature, specific timing and estimated costs of the efforts that will be necessary to complete the remainder of the development of, or the period, if any, in which material net cash inflows may commence from our product candidates. This is due to the numerous risks and uncertainties associated with developing drugs, including the uncertainty of:

•the progress, timing or success of our research and development and clinical programs for our product candidates;

45

•the degree to which our ongoing assessment of the data from our recently completed Phase 2 clinical trial of BIOD-123, our lead candidate for an ultra-rapid-acting insulin formulation, and our related chemistry, manufacturing and controls development work, support further clinical development by us or our potential partners;

•our ability to successfully use the data from our Phase 2 clinical trial of BIOD-123 to design and conduct the pivotal clinical trials required by the FDA to secure approval to commercialize that candidate;

•the success of our formulation development work to improve the stability of our newer ultra-rapid-acting insulin analog-based formulations while maintaining the pharmacokinetic and injection site toleration characteristics associated with earlier formulations;

•our ability to conduct the development work necessary to finalize the formulation and design of our dual-chamber glucagon rescue product candidate, as well as the preclinical studies, clinical trials and manufacturing activities necessary to support the filing of an NDA to the FDA for that product candidate;

•the results of our real-time stability programs for our RHI-, insulin analog- and glucagon-based product candidates, including the reproducibility of earlier, smaller scale, stability studies and our ability to accurately project long term stability on the basis of accelerated testing;

•our ability to accurately anticipate technical challenges that we may face in the development of our ultra-rapid-acting RHI- and insulin analog-based product candidates or our glucagon rescue product candidates;

•our ability to secure approval by the FDA for our product candidates under Section 505(b)(2) of the FFDCA;

•our ability to enter into collaboration arrangements for the commercialization of our product candidates and the success or failure of any such collaborations into which we enter, or our ability to commercialize our product candidates ourselves;

•our ability to enforce our patents for our product candidates and our ability to secure additional patents for our product candidates;

•our ability to protect our intellectual property and operate our business without infringing upon the intellectual property rights of others;

•the degree of clinical utility of our product candidates, particularly with regard to our ultra-rapid-acting insulin formulations, which have not yet been shown to be clinically superior to existing rapid-acting insulin analogs;

•the emergence of competing technologies and products and other adverse market developments, such as advancements in glucagon stabilization technologies that could enable a room-temperature rescue product in a portable, easy to use presentation;

•the ability of our contract manufacturing organizations or collaborators to produce our products in our final dosage form;

•our ability to secure adequate supplies of active pharmaceutical ingredients to support our product development programs and, if successful, the commercialization one or more product candidates;

•our capabilities and strategies for manufacturing, marketing and commercializing a product candidate; and

•our ability to accurately estimate anticipated operating losses, future revenues, capital requirements and our needs for additional financing.

A change in the outcome of any of these variables with respect to the development of ultra-rapid-acting insulin formulations or our liquid glucagon formulation, could mean a significant change in the costs and timing associated with product development.

General and Administrative Expenses

General and administrative expenses consist primarily of salaries and related expenses for personnel, including stock-based compensation expenses, relating to our internal executive, legal, accounting, finance and information technology departments. Other general and administrative expenses include facility-related costs not otherwise allocated to research and development expense, patent expenses, travel expenses, costs associated with industry conventions and professional fees, such as legal and accounting fees and consulting costs.

We anticipate that our general and administrative expenses in the fiscal year ending September 30, 2014 will remain substantially the same as in the fiscal year ended September 30, 2013 as we continue to focus our efforts on product formulation activities and begin advancing our product candidates into later stage clinical trials, including Phase 3 pivotal trials. Over the longer term, however, these expenses could increase as we prepare to file an NDA in support of our dual chamber glucagon rescue product candidate and, possibly, commence pre-commercialization activities.

Warrant Liability

In June 2012, we issued warrants to purchase 2,749,469 shares of our common stock at an exercise price of $2.66 per share in connection with our June 2012 private placement. These warrants will expire on June 26, 2017, five years from the original issuance date of June 27, 2012. In May 2011, we issued warrants to purchase 2,256,929 shares of our common stock at an exercise price of $9.92 per share in connection with our May 2011 registered direct offering. These warrants will expire on May 17, 2016, five years from the original issuance date of May 18, 2011. Under the terms of both the 2012 warrants and the 2011 warrants, if we enter into a merger or change of control transaction, the holders of the warrants will be entitled to receive consideration as if they had exercised the warrants immediately prior to such transaction, or they may require us to purchase the unexercised warrants at the Black-Scholes value (as defined in the applicable warrant) of the warrant on the date of such transaction. The holders have up to 30 days following any such transaction to exercise this right. As a result of this provision, we recognize the 2012 and 2011 warrants as liabilities at their fair value on each reporting date.

We use the Black-Scholes valuation model to estimate the fair value of the warrants. The Black-Scholes valuation model takes into account, as of the valuation date, factors including the current exercise price, the expected life of the warrant, the current price of the underlying stock and its expected volatility, expected dividends on the stock, and the risk-free interest rate for the term of the warrant. Using this model, we recorded an initial warrant liability of $4.8 million for the 2012 warrants and $9.4 million for the 2011 warrants, in each case as of the initial warrant issuance date. The significant assumptions for the model used for the 2012 warrants were remaining terms of the warrants, the common stock price of $3.15 per share, the warrant exercise price of $2.66 per share, a risk-free interest rate of 0.63% and an expected volatility rate of 82%. The significant assumptions for the model used for the 2011 warrants were remaining terms of the warrants, the common stock price of $3.15 per share, the warrant exercise price of $9.92 per share, a risk-free interest rate of 0.63% and an expected volatility rate of 77%. The liability for both the 2012 and 2011 warrants is revalued at each reporting period and changes in fair value are recognized currently in the statements of operations under the caption "Adjustment to fair value of common stock warrant liability."

In August 2010, we issued warrants to purchase 599,550 shares of our common stock in connection with our August 2010 registered direct offering. On December 1, 2011, the unexercised warrants to purchase 589,000 shares of common stock expired. We revalued the liability from September 30, 2011 through the date of expiration and there was no impact on the statement of operations. The common stock warrant liability associated with these warrants no longer exists.

Interest Income

Interest income consists of interest earned on our cash and cash equivalents and marketable securities. In November 2007, our board of directors approved investment policy guidelines, the primary objectives of which are the preservation of capital, the maintenance of liquidity and maintenance of appropriate fiduciary control, subject to our business objectives and tax situation. We have maintained an investment strategy of investing primarily in a premier commercial money market account, which consists primarily of short-term debt securities issued by the U.S. government, Treasury securities and U.S. government agencies. We intend to maintain this conservative strategy in fiscal year ending September 30, 2014.

Critical Accounting Policies and Significant Judgments and Estimates

Our management's discussion and analysis of our financial condition and results of operations is based on our audited financial statements that have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements, as well as the reported expenses during the reporting periods. On an ongoing basis, we evaluate our estimates and assumptions. We base our estimates on historical experience and on various assumptions that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

While our significant accounting policies are more fully described in Note 2 to our financial statements appearing at the end of this Annual Report on Form 10-K, we believe that the following accounting policies, which we have discussed with our audit committee, are the most critical to aid you in fully understanding and evaluating our financial condition and results of operations.

Preclinical Study and Clinical Trial Accruals

In preparing our financial statements, we must estimate accrued expenses pursuant to contracts with multiple research institutions, clinical research organizations and contract manufacturers that conduct and manage preclinical studies, clinical trials and manufacture product for these trials on our behalf. This process involves communicating with relevant personnel to identify services that have been performed on our behalf and estimating the level of services performed and the associated costs incurred for services when we have not yet been invoiced for or otherwise notified of the actual cost. We make estimates of our accrued expenses as of each balance sheet date in our financial statements based on facts and circumstances known to us. The financial terms of these agreements vary and may result in uneven payment flows. To date, we have not adjusted our estimates at any balance sheet date in any material amount. Examples of preclinical study, clinical trial and manufacturing expenses include the following:

•fees paid to contract research organizations in connection with preclinical and toxicology studies and clinical trials;

•fees paid to investigative sites in connection with clinical trials;

•fees paid to contract manufacturers in connection with the production of clinical trial materials; and

•professional service fees.

Government Grants

Grants received are recognized as grant income when the grants become receivable, provided there is reasonable assurance that we will comply with the conditions attached to the grant and there is reasonable assurance the grant will be received. We request cash funding under approved grants as expenses are incurred (not in advance) and report these receipts on the statement of operations as a separate line item entitled "Government Grants." The corresponding expenses are included in research and development expenses. In July and September 2012, we were awarded two National Institutes of Health grants for the development of concentrated ultra-rapid-acting insulin formulations and liquid glucagon formulations, respectively, for use in an artificial pancreas. Both awards are for two years and total approximately $580 thousand each. Work on the grant for the development of concentrated ultra-rapid-acting insulin formulation started in August 2012 and expenses incurred were $327 thousand during the twelve months ended September 30, 2013. Work on the grant for the development of novel and stable glucagon formulations for closed loop systems started in January 2013, and expenses incurred were $219 thousand during the twelve months ended September 30, 2013. Corresponding income and receivables were recorded.

Reclassifications

Certain items in the prior year's financial statements have been reclassified to conform with the current year's presentation.

Share-Based Compensation

Stock Incentive Plan

In March 2013, the shareholders approved the amended and restated 2010 Stock Incentive Plan (the "2010 Plan"). Up to 3,750,000 shares of common stock may be issued pursuant to awards granted under the 2010 Plan, plus 1,540,739 shares of common stock underlying already outstanding awards under the Company's prior plans. As of September 30, 2013, we had 1,951,347 shares of common stock subject to outstanding awards. The contractual life of options granted under the 2010 Plan may not exceed seven years. The 2010 Plan uses a "fungible share" concept under which any awards that are not a full-value award will be counted against the share limit as one (1) share for each share of common stock and any award that is a full-value award will be counted against the share limit as 1.5 shares for each one share of common stock. We have not made any new awards under any prior equity plans after March 2, 2010, the effective date the 2010 Plan was approved by the stockholders. The 2010 Plan replaces the 2004 Stock Incentive Plan and 2005 Non-Employee Directors Stock Option Plan.

We use the Black-Scholes pricing model to calculate the fair value of stock options. The expected life for these grants was calculated in accordance with the simplified method described in the Securities and Exchange Commission Staff Accounting Bulletin (SAB) Topic 14.D.2 in accordance with SAB No. 110.

We recognize compensation costs related to share-based transactions, including employee stock options, in the financial statements based on fair value. The fair value of the stock underlying the options is a significant factor in determining credits or charges to operations appropriate for the share-based payments to both employees and non-employees.

We base our estimate of expected volatility on the historical volatility of our stock. The risk free rate of interest for periods within the contractual life of the stock option is based on the yield of a U.S. Treasury strip on the date the award is granted with a maturity equal to the expected term of the award. We estimate forfeitures based on actual forfeitures during our limited history. Additionally, we have assumed that dividends will not be paid.

For options granted to non-employees and non-directors, primarily consultants who served on our Scientific Advisory Board, we measure fair value of the equity instruments utilizing the Black-Scholes valuation model, if that value is more reliably measurable than the fair value of the consideration or service received. The fair value of these equity investments were periodically revalued as the options were vesting and were recognized as expense over the related period of service or the vesting period, whichever was longer. We have not granted options to non-employees and non-directors since the year ending September 30, 2008. Prior to September 30, 2008, we issued to these non-employees options to purchase an aggregate of 94,278 shares of our common stock. All of these options are currently vested. For the years ended September 30, 2011, 2012 and 2013, the share-based compensation expense (income) related to these options was ($0.04) million, $0, and $0, respectively.

We grant restricted stock units, or RSUs, to executive officers and employees pursuant to the 2010 Plan, from time to time. Each RSU represents one share of common stock. There is no direct cost to the recipients of RSUs, except for any applicable taxes. Except as set forth below with regard to RSUs awarded to employees in place of discretionary cash bonuses, each award vests in installments on each anniversary of the date of grant, and the costs of the awards are determined as the fair market value of the shares on the date of grant. In all cases, costs are expensed per the vesting schedule outlined in the award. For example, RSUs awarded in December 2010 vest annually over three years, with 50% vesting on the first anniversary of the date of grant and the remainder vesting in two equal installments on each anniversary thereafter, and therefore are expensed 50% in the first year and 25% each year in the next two years. Except as set forth below with regard to RSUs awarded to employees in place of discretionary cash bonuses, each year following the annual vesting date, between January 1st and March 15th, we will issue common stock for each vested RSU. During the period when the RSU is vested but not distributed, the RSUs cannot be transferred and the grantee has no voting rights. If we declare a dividend, RSU recipients will receive payment based upon the percentage of RSUs that have vested prior to the date of declaration.

In March 2012, we granted RSUs to our employees in place of the discretionary cash bonuses that were established in connection with the fiscal year ended September 30, 2011. The cost of these awards was

49

determined to be the value of the discretionary cash bonuses. These RSUs vested, and the underlying shares were distributed, on September 30, 2012. At that time, the value of the discretionary cash bonuses exceeded the fair market value of the corresponding RSUs.

For the year ended September 30, 2013, the share-based compensation expense, including expenses associated with stock options and RSUs, was $1.5 million, of which $0.7 million is reflected in research and development expenses and $0.8 million is reflected in general and administrative expenses. For the year ended September 30, 2012, the share-based compensation expense, including expenses associated with stock options and RSUs, was $1.8 million, of which $0.7 million is reflected in research and development expenses and $1.1 million is reflected in general and administrative expenses. For the year ended September 30, 2011, the share-based compensation expense was $5.0 million, of which $2.0 million is reflected in research and development expenses and $3.0 million is reflected in general and administrative expenses.

Income Taxes

As part of the process of preparing our financial statements, we are required to estimate our income taxes in each of the jurisdictions in which we operate. This process involves estimating our actual current tax expense together with assessing temporary differences resulting from differing treatments of items for tax and accounting purposes. These differences result in deferred tax assets and liabilities.

At September 30, 2012 and 2013, we recorded a 100% valuation allowance against our net deferred tax asset of approximately $47.9 million and $55.0 million, respectively, as our management believes it is uncertain that it will be fully realized. If we determine in the future that we will be able to realize all or a portion of our net deferred tax asset, an adjustment to the deferred tax valuation allowance would increase net income in the period in which we make such a determination.

As of September 30, 2013, we had net operating loss carry-forwards of approximately $57.6 million for U.S. federal and $112.2 million for state tax purposes. These loss carry-forwards expire between 2024 and 2032. To the extent these net operating loss carry-forwards are available, we intend to use them to reduce the corporate income tax liability associated with our operations. Section 382 of the U.S. Internal Revenue Code generally imposes an annual limitation on the amount of net operating loss carry-forwards that might be used to offset taxable income when a corporation has undergone significant changes in stock ownership. Based on a Section 382 analysis review, we determined that an ownership change under Section 382 occurred on May 12, 2011. We believe that approximately $55.9 million of the $112.2 million federal losses will expire unused as a result of Section 382 limitations. The maximum annual limitation under Section 382 is approximately $2.5 million for 20 years. To the extent our use of net operating loss carry-forwards is limited, future income could be subject to corporate income tax earlier than it would if we were able to use net operating loss carry-forwards, which could result in decreased net income.

We also have state research and development credit carry-forwards of approximately $0.3 million, which expire commencing in fiscal 2022.

Research and development expenses were $14.3 million for the year ended September 30, 2013, an increase of $2.0 million, or approximately 16.1%, from $12.3 million for the year ended September 30, 2012. This increase was primarily attributable to increases of $1.2 million in external expenses associated with our clinical trials, $0.4 million in personnel and stock-based compensation expenses, $0.2 million in consulting fees, and $0.1 million in preclinical animal studies.

Research and development expenses for the year ended September 30, 2013 and 2012 include $0.7 million each in stock-based compensation expense related to options granted to employees.

In July and September 2012, we received two National Institutes of Health awards for the development of concentrated ultra-rapid-acting insulin formulation and glucagon formulation for use in an artificial pancreas. The July 2012 award is intended to fund research to develop a proprietary ultra-rapid-insulin product candidate at high concentrations suited to provide sufficient quantities of insulin in an external artificial pancreas pump device that has limited volume capacity. The July award is for two years and totals $582 thousand. The September 2012 award is intended to fund research to develop a proprietary glucagon product candidate optimized to algorithmically deliver glucagon as part of a bi-hormonal closed loop system to mitigate hypoglycemic events. The September 2012 award is for two years and totals $583 thousand. For the year ended September 30, 2013, we reported $327 thousand in government grants for the high concentration ultra-rapid-insulin product candidate and $219 thousand for the glucagon formulation work.

General and Administrative Expenses.

		Year Ended September 30,						Decrease
		2012			2013			$	%
		In thousands, except per share amounts
General and Administrative	$	7,072		$	6,843		$	229	3.2	%
Percentage of net loss		34.1	%		35.4	%

General and administrative expenses were $6.8 million for the year ended September 30, 2013, a decrease of $0.2 million, or 3.2%, from $7.1 million for the year ended September 30, 2012. This decrease is primarily attributable to the adjusted allocation of bonus expense between general and administrative and research and development, which decreased general and administrative expense by $0.3 million when compared to the year ended September 30, 2012.

General and administrative expenses for the year ended September 30, 2013 and 2012 include $0.8 million and $1.1 million, respectively, in stock-based compensation expense related to options granted to employees and non-employee directors.

Interest and other income decreased to $0.06 million for the year ended September 30, 2013 from $0.08 million for the year ended September 30, 2012. The decrease is primarily due to lower cash balances during the year.

51

Interest Expense. For the years ended September 30, 2013 and 2012, we had no interest expense.

Adjustments to Fair Value of Common Stock Warrant Liability.

		Year Ended September 30,						Decrease

Total	$	1,510		$	(1,217	)	$	2,727			180.6	%
Percentage of net loss		128.4	%		59.4	%

The change in fair value of derivative instruments-warrants of $1,510 during the year ended September 30, 2012 was primarily a result of the increase in the price of the common stock from $2.16 per share at September 30, 2011 to $2.97 per share at September 30, 2012. The change in fair value of common stock warrant liability of $(1,217) during the year ended September 30, 2013 was primarily due to shorter terms and reduced volatility.

Net Loss and Net Loss per Share.

		Year Ended September 30,						Decrease

Net loss	$	(20,747	)	$	(19,335	)	$	1,412	6.8	%
Net loss per share	$	(1.91	)	$	(1.24	)

Net loss was $19.3 million, or $(1.24) per share, for the year ended September 30, 2013, compared to $20.7 million, or $(1.91) per share, for the year ended September 30, 2012. The decrease in net loss was primarily due to a decrease in adjustments to fair value of common stock warrant liability and general and administrative expenses, offset by an increase in research and development expenses as noted above.

Year Ended September 30, 2012 Compared to Year Ended September 30, 2011

Revenue. We did not recognize any revenue during the years ended September 30, 2012 or 2011.

Research and Development Expenses.

		Year Ended September 30,						Decrease
		2011			2012			$	%
		In thousands, except per share amounts
Research and Development	$	13,597		$	12,315		$	1,282	9.4	%
Percentage of net loss		128.4	%		59.4	%

Research and development expenses were $12.3 million for the year ended September 30, 2012, a decrease of $1.3 million or 9.4%, from $13.6 million for the year ended September 30, 2011. This decrease was primarily attributable to reductions of $2.6 million in manufacturing expenses and $0.4 million in regulatory expenses. These decreases were offset in part by an increase of $1.4 million in clinical expenses related primarily to our Phase 1 clinical trial of BIOD-123 and BIOD-125 and a net increase of $0.3 million in research and development expenses related to an increase in the number of preclinical animal studies we conducted and a licensing fee paid to Aegis.

The reductions in manufacturing expenses are attributable to savings of $2.2 million as a result of renegotiating the terms of our supply agreement for RHI and $0.4 million in reduced personnel costs. The

52

$0.4 million reduction in regulatory expenses resulted from lower professional fees for the year ended September 30, 2012, as compared to 2011, and lower stock-based compensation costs.

Research and development expenses for the twelve months ended September 30, 2011 were reduced by our receipt in January 2011 of approximately $1.2 million in research grants under the Internal Revenue Service's therapeutic tax credit program and were increased by a $1.4 million severance charge resulting from the retirement of our former Chief Scientific Officer.

Research and development expenses for the years ended September 30, 2012 and 2011 include $0.7 million and $1.9 million, respectively, in stock-based compensation expense related to options granted to employees.

In July and September 2012, we received two National Institutes of Health awards for the development of concentrated ultra-rapid-acting insulin formulation and glucagon formulation for use in an artificial pancreas. The July 2012 award is intended to fund research to develop a proprietary ultra-rapid-insulin product candidate at high concentrations suited to provide sufficient quantities of insulin in an external artificial pancreas pump device that has limited volume capacity. The July award is for two years and totals $582 thousand. The September 2012 award is intended to fund research to develop a proprietary glucagon product candidate optimized to algorithmically deliver glucagon as part of a bi-hormonal closed loop system to mitigate hypoglycemic events. The September 2012 award is for two years and totals $583 thousand. For the year ended September 30, 2012, we reported $88 thousand in government grants for the high concentration ultra-rapid-insulin product candidate and did not start the glucagon formulation work.

		Year Ended September 30,						Decrease
		2011			2012			$	%
		In thousands, except per share amounts
General and Administrative	$	9,625		$	7,072		$	2,553	26.5	%
Percentage of net loss		90.9	%		34.1	%

General and administrative expenses were $7.1 million for the year ended September 30, 2012, a decrease of $2.6 million, or 26.5%, from $9.6 million for the year ended September 30, 2011. This decrease is attributable to reductions of $0.2 million in depreciation expense due primarily to fully depreciating our accounting software, $1.9 million in employee and non-employee director stock-based compensation expenses, and other expenses of $0.4 million. General and administrative expenses for the year ended September 30, 2012 and 2011 include $1.1 million and $3.0 million, respectively, in stock-based compensation expense related to options granted to employees and non-employee directors.

Interest and Other Income.

Interest and other income increased to $0.08 million for the year ended September 30, 2012 from $0.06 million for the year ended September 30, 2011. The increase resulted primarily from interest on the higher cash balances generated by our June 2012 private placement.

Interest Expense. For the years ended September 30, 2012 and 2011, we had no interest expense.

Adjustments to fair value of common stock warrant liability
August 2010 Warrant	��	$	(4,169	)	$	—		$	4,169

Total		$	(12,611	)	$	1,510		$	14,121	112.0	%
Percentage of net loss			119.1	%		7.3	%

The change in fair value of derivative instruments-warrants of $(12,611) during the year ended September 30, 2011 was primarily a result of the decrease in the price of the common stock from $5.30 per share at September 30, 2010 to $2.16 per share at September 30, 2011. The change in fair value of common stock warrant liability of $1,510 during the year ended September 30, 2012 was a result of the increase in the price of the common stock from $2.16 per share at September 30, 2011 to $2.97 per share at September 30, 2012.

Net loss was $20.7 million, or $(1.91) per share, for the year ended September 30, 2012, compared to $10.6 million, or $(1.36) per share, for the year ended September 30, 2011. The increase in net loss was primarily due to an increase in adjustments to fair value of common stock warrant liability, as noted above.

Liquidity and Capital Resources

Sources of Liquidity and Cash Flows

As a result of our significant research and development expenditures and the lack of any approved products or other sources of revenue, we have not been profitable and have generated significant operating losses since we were incorporated in 2003. We initially funded our research and development operations through aggregate gross proceeds of $26.6 million from our private financing transactions that we completed prior to our initial public offering. We received an aggregate of approximately $202 million from our initial public offering in May 2007, our follow-on offering in February 2008, our registered direct offerings in August 2010 and May 2011, our private placement in June 2012 and our public offering in June 2013.

At September 30, 2013, we had cash and cash equivalents totaling approximately $39.8 million. We plan to continue to invest our cash and cash equivalents in accordance with our approved investment policy guidelines.

Net cash used in operating activities was $18.6 million for the year ended September 30, 2013, $16.7 million for the year ended September 30, 2012, and $18.3 million for the year ended September 30, 2011. Net cash used in operating activities for the years ended September 30, 2013, 2012 and 2011 primarily reflects the net loss for the period, offset in part by depreciation and amortization, share-based compensation and changes in the fair value of the common stock-warrant liability.

Net cash (used in) provided by investing activities was $(0.1) million for the year ended September 30, 2013, $(0.06) million for the year ended September 30, 2012, and $5.8 million for the year ended September

54

30, 2011. Net cash used in investing activities for the years ended September 30, 2013 and 2012 reflects the purchase of property and equipment. Net cash provided by investing activities for the year ended September 30, 2011 primarily reflects the sale of marketable securities offset by the purchase of property and equipment.

Net cash provided by financing activities was $19.4 million for the year ended September 30, 2013, $17.1 million for the year ended September 30, 2012, and $28.2 million for the year ended September 30, 2011. Net cash provided by financing activities for the year ended September 30, 2013 primarily reflects proceeds from the sale of our securities in our underwritten public offering in June 2013 and through our employee stock purchase plan. Net cash provided by financing activities in 2012 primarily reflects proceeds from the sale our securities in our private placement offering in June 2012 and through our employee stock purchase plan. Net cash provided by financing activities in 2011 primarily reflects proceeds from the sale of our securities in our registered direct offering in May 2011 and through our employee purchase plan.

In June 2013, we completed an underwritten public offering of securities in which we issued 4,482,760 shares of our common stock at a price to the public of $4.35 per share. In July 2013 we issued 236,007 additional shares of common stock, at the public offering price of $4.35 per share, in connection with the underwriters' exercise of a portion of their over-allotment. We received net proceeds, after deducting placement agent fees and other offering expenses of approximately $19.2 million from this financing.

In June 2012, we completed a private placement of securities in which we issued 4,250,020 shares of our common stock, 3,605,607 shares of our Series B preferred stock and warrants to purchase 2,749,469 shares of our common stock. We received net proceeds, after deducting placement agent fees and other offering expenses, of approximately $17.1 million from this financing.

In May 2011, we completed a registered direct offering of an aggregate of 3,018,736 shares of our common stock, 1,813,944 shares of our Series A Preferred Stock and warrants to purchase 2,256,929 shares of our common stock at an exercise price of $9.92 per share. The warrants will expire on May 17, 2016. We received net proceeds, after deducting placement agent fees and other offering expenses, of approximately $28.0 million from this financing.

In August 2010, we completed a registered direct offering of an aggregate of 599,550 shares of our common stock and warrants to purchase an additional 559,550 shares of our common stock at an initial exercise price of $18.86 per share. We received net proceeds, after deducting placement agent fees and other offering expenses, of approximately $8.7 million from this financing. In December 2010, the exercise price of the warrants was reset to $6.24 per share and in May 2011, the exercise price of the warrants was reset to $4.70 per share. In August 2011, warrants for a total of 10,550 shares were exercised and we received proceeds of approximately $50 thousand. The remaining warrants for 589,000 shares expired unexercised on December 1, 2011.

Funding Requirements

We believe that our existing cash and cash equivalents will be sufficient to fund our anticipated operating expenses and capital expenditures at least until the second calendar quarter of 2015. We have based this estimate upon assumptions that may prove to be wrong and we could use our available capital resources sooner than we currently expect. Our existing capital resources are not sufficient to complete our clinical development program for an ultra-rapid-acting insulin product candidate. Because of the numerous risks and uncertainties associated with the development and commercialization of our product candidates, and to the extent that we may or may not enter into collaborations with third parties to participate in their development and commercialization, we are unable to estimate the amounts of increased capital outlays and operating expenditures associated with our current anticipated clinical trials.

Our future capital requirements will depend on many factors, including:

•the progress, timing or success of our research and development and clinical programs for our product candidates;

•the degree to which our ongoing assessment of the data from our recently completed Phase 2 clinical trial of BIOD-123, our lead candidate for an ultra-rapid-acting insulin formulation, and our related chemistry, manufacturing and controls development work, support further clinical development by us or our potential partners;

55

•our ability to successfully use the data from our Phase 2 clinical trial of BIOD-123 to design and conduct the pivotal clinical trials required by the or FDA to secure approval to commercialize that candidate;

•the success of our formulation development work to improve the stability of our newer ultra-rapid-acting insulin analog-based formulations while maintaining the pharmacokinetic and injection site toleration characteristics associated with earlier formulations;

•our ability to conduct the development work necessary to finalize the formulation and design of our dual-chamber glucagon rescue product candidate, as well as the preclinical studies, clinical trials and manufacturing activities necessary to support the filing of an NDA to the FDA for that product candidate;

•the results of our real-time stability programs for our RHI-, insulin analog- and glucagon-based product candidates, including the reproducibility of earlier, smaller scale, stability studies and our ability to accurately project long term stability on the basis of accelerated testing;

•our ability to accurately anticipate technical challenges that we may face in the development of our ultra-rapid-acting RHI- and insulin analog-based product candidates or our glucagon rescue product candidates;

•our ability to secure approval by the FDA for our product candidates under Section 505(b)(2) of the FFDCA;

•our ability to enter into collaboration arrangements for the commercialization of our product candidates and the success or failure of any such collaborations into which we enter, or our ability to commercialize our product candidates ourselves;

•our ability to enforce our patents for our product candidates and our ability to secure additional patents for our product candidates;

•our ability to protect our intellectual property and operate our business without infringing upon the intellectual property rights of others;

•the degree of clinical utility of our product candidates, particularly with regard to our ultra-rapid-acting insulin formulations, which have not yet been shown to be clinically superior to existing rapid-acting insulin analogs;

•the emergence of competing technologies and products and other adverse market developments, such as advancements in glucagon stabilization technologies that could enable a room-temperature rescue product in a portable, easy to use presentation;

•the ability of our contract manufacturing organizations or collaborators to produce our products in our final dosage form;

•our ability to secure adequate supplies of active pharmaceutical ingredients to support our product development programs and, if successful, the commercialization one or more product candidates;

•our capabilities and strategies for manufacturing, marketing and commercializing a product candidate; and

•our ability to accurately estimate anticipated operating losses, future revenues, capital requirements and our needs for additional financing.

We do not anticipate generating product revenue for the next few years. In the absence of additional funding, we expect our continuing operating losses to result in increases in our cash used in operations over the next several years. To the extent our capital resources are insufficient to meet our future capital requirements, we will need to finance our future cash needs through public or private equity offerings, debt financings or corporate collaboration and licensing arrangements. We do not currently have any commitments for future external funding.

We may receive additional proceeds from the exercise of the warrants that we issued in connection with our May 2011 registered direct offering and our June 2012 private placement, if any of those warrants are

56

exercised for cash. Whether the warrants are exercised for cash will depend on decisions made by the warrant holders and on whether the market price of our common stock exceeds the $9.92 per share warrant exercise price of the May 2011 warrants or the $2.66 per share warrant exercise price of the June 2012 warrants. The May 2011 warrants and the June 2012 warrants will expire on May 17, 2016 and June 26, 2017, respectively.

While we continue to pursue cost saving initiatives to reduce operating expenses, we will also need to raise additional funds and periodically explore sources of equity or debt financing. We may seek to raise such capital through public or private equity financings, partnerships, joint ventures, debt financings, bank borrowings or other sources. However, additional funding may not be available on favorable terms or at all. If additional funds are raised by issuing equity securities, substantial dilution to existing shareholders may result. If we fail to obtain additional capital when needed, we may be required to delay, scale back, or eliminate some or all of our research and development programs. The accompanying financial statements do not include any adjustments that may result from the outcome of this uncertainty.

Off-Balance Sheet Arrangements

We have no off-balance sheet arrangements.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Our exposure to market risk is limited to our cash, cash equivalents and marketable securities. We invest in high-quality financial instruments, as permitted by the terms of our investment policy guidelines. Currently, our excess funds are invested in a premium commercial money market fund with one major financial institution. We do not hedge interest rate exposure. A portion of our investments may be subject to interest rate risk and could fall in value if interest rates were to increase.

Because most of our transactions are denominated in United States dollars, we do not have any material exposure to fluctuations in currency exchange rates.

ITEM 9A. CONTROLS AND PROCEDURES

Management's Evaluation of Disclosure Controls and Procedures

We are required to maintain disclosure controls and procedures designed to ensure that material information related to us is recorded, processed, summarized and reported within the time periods specified in the SEC rules and forms. The term "disclosure controls and procedures," as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended, or the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC's rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company's management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

Our management, with the participation of our chief executive officer and chief financial officer, evaluated the effectiveness of our disclosure controls and procedures as of September 30, 2013 and, based on this evaluation, our chief executive officer and chief financial officer have concluded that, as of the end of the period covered by this report, our disclosure controls and procedures were effective.

Management's Annual Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting for the company. Internal control over financial reporting is defined in Rule 13a-15(f) or 15d-15(f) promulgated under the Securities Exchange Act of 1934 as a process designed by, or under the supervision of, the company's principal executive and principal financial officers and effected by the company's board of directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles and includes those policies and procedures that:

•pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of the company;

•provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and

•provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the company's assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

58

Our management assessed the effectiveness of our internal control over financial reporting as of September 30, 2013. In making this assessment, our management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control-Integrated Framework (1992).

Based on our assessment, management concluded that, as of September 30, 2013, our internal control over financial reporting is effective based on those criteria.

Changes in Internal Control over Financial Reporting

No change in our internal control over financial reporting occurred during the fiscal quarter ended September 30, 2013 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Report of Independent Registered Public Accounting Firm

Board of Directors and Stockholders
Biodel Inc.
Danbury, Connecticut

We have audited the accompanying balance sheets of Biodel Inc. (a development stage company) as of September 30, 2013 and 2012 and the related statements of operations, stockholders' equity and cash flows for each of the three years in the period ended September 30, 2013 and the statements of operations, stockholders' equity and cash flows for the period from December 3, 2003 (inception) to September 30, 2013. These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Company is not required to have, nor were we engaged to perform an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of Biodel Inc. as of September 30, 2013 and 2012, and the results of its operations and its cash flows for each of the three years in the period ended September 30, 2013, and for the period from December 3, 2003 (inception) to September 30, 2013, in conformity with accounting principles generally accepted in the United States.

Biodel Inc. and its wholly owned subsidiary (collectively, "Biodel" or the "Company", and formerly Global Positioning Group Ltd.) is a development stage specialty pharmaceutical company located in Danbury, Connecticut. The Company was incorporated in the State of Delaware on December 3, 2003 and commenced operations in January 2004. The Company formed a wholly owned subsidiary in the United Kingdom in October 2011 ("Biodel UK Limited"). This subsidiary has been inactive since its inception.

The Company focuses on the development and commercialization of innovative treatments for diabetes that may be safer, more effective and more convenient for patients. The Company's develops its product candidates by applying its proprietary formulation technologies to existing drugs in order to improve their therapeutic profiles. The Company's proprietary insulin formulations are designed to be more rapid-acting than the formulations currently available to Type 1 and Type 2 diabetes patients. The Company refers to these as "ultra-rapid-acting" formulations. The Company's glucagon formulations and presentations are designed to be stable at room temperature and are intended for use by caregivers with no medical training as a rescue treatment for diabetes patients experiencing severe hypoglycemia, or very low concentrations of blood glucose.

The Company's most advanced ultra-rapid-acting insulin formulation, BIOD-123, combines recombinant human insulin, or RHI, with the Company's proprietary combination of excipients to increase the rate of absorption following injection when compared to other commercially available insulin formulations, including "rapid-acting" mealtime insulin analogs such as Humalog®, marketed by Eli Lilly, Novolog®, marketed by Novo Nordisk and Apidra®, marketed by Sanofi-Aventis. The Company is also using its proprietary excipients to develop ultra-rapid-acting insulin analog-based formulations using either insulin lispro, the active pharmaceutical ingredient in Humalog®, or insulin aspart, the active pharmaceutical ingredient in NovoLog®.

In addition the Company also has other products in the development stage.

Basis of Presentation

The Company is in the development stage, as defined by Financial Accounting Standards Board ("FASB") ASC 915 (prior authoritative literature: Statement of Financial Accounting Standards No. 7), "Accounting and Reporting by Development Stage Enterprises", as its primary activities since incorporation have been establishing its facilities, recruiting personnel, conducting research and development, business development, business and financial planning and raising capital.

On June 11, 2012, the Company effected a one-for-four reverse split of its outstanding common stock. All references in these financial statements and accompanying notes to units of common stock or per share amounts are reflective of the reverse split for all periods reported. (See Note 12.)

2. Summary of Significant Accounting Policies

Research and Development Costs

The Company is in the business of research and development and, therefore, research and development costs include, but are not limited to, salaries and benefits, lab supplies, preclinical fees, clinical trial and related clinical manufacturing costs, allocated overhead costs and professional service providers. Research and development costs are expensed when incurred. Research and development costs aggregated $13,597, $12,315, and $14,296 for the years ended September 30, 2011, 2012 and 2013, respectively.

Government Grants

Grants received are recognized as grant income when the grants become receivable, provided there is reasonable assurance that the Company will comply with the conditions attached to the grant and there is

F-9

Biodel Inc.

(A Development Stage Company)

Notes to Financial Statements — (Continued)

(In thousands, except share and per share amounts)

reasonable assurance the grant will be received. The Company requests cash funding under approved grants as expenses are incurred (not in advance) and report these receipts on the statement of operations as a separate line item entitled "Government Grants" with the corresponding expenses included in research and development. In July and September 2012, the Company was awarded two National Institutes of Health grants for the development of concentrated ultra-rapid-acting insulin formulation and glucagon formulation, respectively, for use in an artificial pancreas. Both awards are for two years and total approximately $580 each. Work on the grant for the development of concentrated ultra-rapid-acting insulin formulation started in August 2012 and expenses incurred were $327 during the year ended September 30, 2013 and $88 for the year ended September 30, 2012. Work on the grant for the development of novel and stable glucagon formulations for closed loop systems started in January 2013, and expenses incurred were $219 during the year ended September 30, 2013. Corresponding income and receivable were recorded.

Use of Estimates

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. On an ongoing basis, the Company evaluates its estimates and assumptions including, but not limited to, accruals, income taxes payable, forfeiture rate used in the computation of share-based compensation and deferred tax assets. Actual results may differ from those estimates.

Cash and Cash Equivalents

The Company considers currency on hand, demand deposits and all highly liquid investments with an original maturity of three months or less at the date of purchase to be cash and cash equivalents. As of September 30, 2012 and 2013, the Company had cash and cash equivalents of $39,050 and $39,781, respectively, and they are primarily held in a premium commercial money market account.

Restricted Cash

Restricted cash was $60 and $0 as of September 30, 2012 and 2013. This amount was held in a money market account with a bank to secure a credit card purchasing agreement utilized to facilitate employee travel and certain ordinary purchases. As of September 30, 2013 the Company canceled the credit card purchasing agreement and the restriction on the cash was lifted.

In February 2012, the Company brought action against one of its vendors before the American Arbitration Association in New York relating to disputed fees charged to the Company for inventory storage. As part of the arbitration stipulation, the Company established a $1,500 escrow account and recorded an accrual of $741 toward this claim. During the quarter ended June 30, 2012, the Company paid $500 from the escrow account. On July 30, 2012, the Company received a judgment from the arbitrator stating the Company's final amount due was $55. The remaining escrow balance of $945 was removed from the escrow account and transferred to cash. The remaining accrual of $186 was reversed and recorded in research and development expense during the quarter ended September 30, 2012.

Fair Value of Financial Instruments

The carrying amounts of the Company's financial instruments, which include cash and cash equivalents and accounts payable, approximate their fair values due to their short term maturities.

Pre-Launch Inventory

Inventory costs associated with product candidates that have not yet received regulatory approval are capitalized if the Company believes there is probable future commercial use and future economic benefit. If

F-10

Biodel Inc.

(A Development Stage Company)

Notes to Financial Statements — (Continued)

(In thousands, except share and per share amounts)

the probability of future commercial use and future economic benefit cannot be reasonably determined, then pre-launch inventory costs associated with such product candidates are expensed as research and development expense during the period the costs are incurred. Because all of its product candidates are in early stages of preclinical or clinical development, the Company currently expenses all purchases of pre-launch inventory as research and development, and expects to continue to do so until it can determine the probability of regulatory approval for the applicable product candidate.

For the years ended September 30, 2012 and 2013, the Company expensed $170 and $121, respectively, of costs associated with the purchase of RHI and glucagon as research and development expense after such materials passed quality control inspection by the Company and transfer of title occurred.

Intellectual Property

Intangible assets consist primarily of capitalized costs associated with the Company's ultra-rapid-acting insulin patents and the purchase of two domain addresses. They are amortized using the straight-line method over twenty years. If the Company determines that a patent will not result in future revenues, the cost related to such patent will be expensed in full on the date of that determination. Intellectual property amortization expense for the years ended September 30, 2011, 2012 and 2013 was $4, $3, and $3, respectively.

Property and Equipment

Property and equipment are stated at cost, net of accumulated depreciation or amortization. Major improvements are capitalized, while maintenance and repairs are expensed in the period the cost is incurred. Property and equipment are depreciated over their estimated useful lives using the straight-line method. Leasehold improvements are amortized using the straight-line method over their estimated useful lives, or the remaining term of the lease, whichever is shorter. When assets are retired or otherwise disposed of, the assets and related accumulated depreciation are removed from the accounts and resulting gains or losses are included in other income (expense) in the statement of operations. Estimated useful lives for each asset category are as follows: Furniture and fixtures — 7 years; Leasehold improvements — estimated useful life or remaining term of lease, whichever is shorter; Laboratory equipment — 7 years; Manufacturing equipment — 5 years; Device development— 5 years; Facility equipment— 3 years and 7 years; Computer equipment — 5 years; and Computer software — 3 years.

Impairment of Long-Lived Assets

Whenever events or changes in circumstances indicate that the carrying amounts of a long-lived asset may not be recoverable, the Company reviews these assets for impairment and determines whether adjustments are needed to carrying values. There were no adjustments to the carrying value of long-lived assets at September 30, 2012 and 2013.

Warrant Liability

The Company applies the provisions of Accounting Standards Codification Topic 480 ("ASC 480") (formerly FASB Staff Position 150-5 (FSP 15-5)), Issuers Accounting under FASB Statement No. 150 for Freestanding Warrants and other Similar Instruments on Shares that are Redeemable or Distinguishing Liabilities from Equities. Pursuant to ASC 480, a freestanding financial instrument (other than outstanding share) that, at inception, embodies an obligation to repurchase the issuer's shares and "requires or may require" the obligation to be settled by transferring assets, qualifies as a liability (if the obligation is conditional, the number of conditions is irrelevant).

The Company issued warrants in June 2012 and recorded a liability determined by the Black-Scholes valuation model. The Black-Scholes valuation model was used because the June 2012 warrants do not contain a repricing provision. The Black-Scholes valuation model takes into account, as of the valuation date, factors

F-11

Biodel Inc.

(A Development Stage Company)

Notes to Financial Statements — (Continued)

(In thousands, except share and per share amounts)

including the current exercise price, the expected life of the warrant, the current price of the underlying stock and its expected volatility, expected dividends on the stock, and the risk-free interest rate for the term of the warrant. These warrants will be revalued at each reporting period and changes in fair value are recognized currently in the statements of operations under the caption "Adjustment to fair value of common stock warrant liability."

The Company issued warrants in May 2011 and recorded a liability determined by the Black-Scholes valuation model. The Black-Scholes valuation model was used because the May 2011 warrants do not contain a repricing provision. These warrants will be revalued at each reporting period and changes in fair value are recognized currently in the statements of operations under the caption "Adjustment to fair value of common stock warrant liability."

The Company issued warrants in August 2010 and recorded a liability determined by the Monte Carlo simulation method, which was used because the August 2010 warrants contain a re-pricing provision. The Monte Carlo simulation is a generally accepted statistical method used to generate a defined number of stock price paths in order to develop a reasonable estimate of the range of future expected stock prices of the Company and its peer group and minimize standard error.

On December 2, 2011, the unexercised warrants to purchase 589,000 shares of common stock expired. The Company revalued the liability associated with these warrants from September 30, 2011 through the date of expiration and there was no material impact on the statement of operations. The common stock warrant liability associated with these warrants no longer exists.

Income Taxes

The Company uses the asset and liability method of accounting for deferred income taxes. The provision for income taxes includes income taxes currently payable and those deferred as a result of temporary differences between the financial statement and tax bases of assets and liabilities. A valuation allowance is provided to reduce deferred tax assets to the amount of future tax benefit when it is more likely than not that some portion of the deferred tax assets will not be realized. Projected future taxable income and ongoing tax planning strategies are considered and evaluated when assessing the need for a valuation allowance. Any increase or decrease in a valuation allowance could have a material adverse or beneficial impact on the Company's income tax provision and net income or loss in the period which the determination is made.

Concentration of Risks and Uncertainties

Financial instruments that potentially subject the Company to a concentration of credit risk consist of cash and cash equivalents. The Company deposits excess cash with major financial institutions in the United States. Balances may exceed the amount of insurance provided on such deposits. The Company believes that its investment policy guideline for its excess cash maintains safety and liquidity through its policies on credit requirements, diversification and investment maturity.

The Company has experienced significant operating losses since inception. At September 30, 2013, the Company had a deficit accumulated during the development stage of $215,428. The Company has generated no revenue to date. The Company has funded its operations to date principally from the sale of securities. The Company expects to incur substantial additional operating losses for the next several years and will need to obtain additional financing in order to complete the clinical development of an ultra-rapid-acting insulin or a glucagon rescue product, launch and commercialize the product if it receives regulatory approval, and continue research and development programs. There can be no assurance that such financing will be available or will be at terms acceptable to the Company.

The Company is currently developing its first product candidates and has no products that have received regulatory approval. Any products developed by the Company will require approval from the FDA or foreign regulatory agencies prior to commercial sales. There can be no assurance that the Company's products will

F-12

Biodel Inc.

(A Development Stage Company)

Notes to Financial Statements — (Continued)

(In thousands, except share and per share amounts)

receive the necessary approvals. If the Company is denied such approvals or such approvals are delayed, it would have a material adverse effect on the Company's future operating results.

To achieve profitable operations, the Company must successfully develop, test, manufacture and market products, as well as secure the necessary regulatory approvals. There can be no assurance that any such products can be developed successfully or manufactured at an acceptable cost and with appropriate performance characteristics, or that such products will be successfully marketed. These factors would have a material adverse effect on the Company's future financial results.

Stock-Based Compensation

In March 2013, the shareholders of the Company approved the amended and restated 2010 Stock Incentive Plan (the "2010 Plan"). Up to 3,750,000 shares of the Company's common stock may be issued pursuant to awards granted under the 2010 Plan, plus 1,540,739 shares of common stock underlying already outstanding awards under the Company's prior plans. As of September 30, 2013, the Company had 1,951,347 shares of common stock subject to outstanding awards. The contractual life of options granted under the 2010 Plan may not exceed seven years. The 2010 Plan uses a "fungible share" concept under which any awards that are not a full-value award will be counted against the share limit as one (1) share for each share of common stock and any award that is a full-value award will be counted against the share limit as 1.5 shares for each one share of common stock. The Company has not made any new awards under any prior equity plans after March 2, 2010, the effective date the 2010 Plan was approved by the Company's stockholders. The 2010 Plan replaces the 2004 Stock Incentive Plan and 2005 Non-Employee Directors Stock Option Plan.

The Company uses the Black-Scholes pricing model to calculate the fair value of stock options. The expected life for grants was calculated in accordance with the simplified method described in the Securities and Exchange Commission Staff Accounting Bulletin (SAB) Topic 14.D.2 in accordance with SAB No. 110.

The risk-free rate of interest for periods within the contractual life of the stock option award is based on the yield of U.S. Treasury strips on the date the award is granted with a maturity equal to the expected term of the award. The Company estimates forfeitures based on actual forfeitures during its limited history. Additionally, the Company has assumed that dividends will not be paid.

For stock options granted to non-employees, the Company measures fair value of the equity instruments utilizing the Black-Scholes valuation model, if that value is more reliably measurable than the fair value of the consideration or service received. The fair value of these instruments is periodically revalued as the options vest, and is recognized as expense over the related period of service or vesting period, whichever is longer. The total cost expensed (credited) for options granted to non-employees for the years ended September 30, 2011, 2012 and 2013 was $(44), $0, and $0, respectively.

The Company expenses ratably over the vesting period the cost of the stock options granted to employees and directors. The total compensation cost for the years ended September 30, 2011, 2012, and 2013 was $4,964, $1,828, and $1,538 respectively. At September 30, 2013, the total compensation cost related to non-vested options not yet recognized was $871, which will be recognized over the next three years assuming the employees complete their service period for vesting of the options. The Black-Scholes valuation model assumptions are as follows and were determined as discussed above:

	Year Ended September 30,
	2011	2012	2013
Expected life (in years)	3.77 - 5.25	3.0 - 4.75	2.39-4.75
Expected volatility	65 - 72%	58 - 76%	80-96%
Expected dividend yield	0%	0%	0%
Risk-free interest rate	0.75 - 1.97%	0.39 - 0.91%	0.25-0.75%
Weighted-average grant date fair value	$6.36	$2.54	$2.43

Participating Securities

In June 2008 the Financial Accounting Standards Board ("FASB") issued ASC 260-10-55 Earnings Per Share — Overall (formerly Financial Statement Position Emerging Issues Task Force 03-6-1, Determining Whether Instruments Granted in Share-Based Payment Transactions Are Participating Securities) ("ASC 260-10-55"). ASC 260-10-55 provides that securities and unvested share-based payment awards that contain non-forfeitable rights to dividends or dividend equivalents (whether paid or unpaid) are participating securities and shall be included in the computation of earnings per share pursuant to the two-class method.

Warrant Liability — Given that the warrant holders will participate fully on any dividends or dividend equivalents, the Company determined that the warrants are participating securities and therefore are subject to ASC 260-10-55. These securities were excluded from the per share calculation for all years since their inclusion would be anti-dilutive.

Restricted Stock Units — Given that the holders of Restricted Stock Unit awards ("RSUs") will only receive dividends or dividend equivalents on RSUs that have vested prior to the Company declaring dividends as well as forfeiting their rights to receive dividends or dividend equivalents on any unvested portion, the Company determined that the RSUs are non-participating securities and therefore are not subject to ASC 260-10-55.

Reclassifications:

Certain items in the prior year's financial statements have been reclassified to conform with the current year's presentation.

3. Fair Value Measurement

ASC Topic 820 ("ASC 820"), originally issued as SFAS No. 157, Fair Value Measurements) applies under other accounting pronouncements that require or permit fair value measurements, the FASB having previously concluded in those accounting pronouncements that fair value is the relevant measurement attribute. Accordingly, ASC 820 does not require any new fair value measurements. The fair value framework requires the categorization of assets and liabilities into three levels based upon the assumptions (inputs) used to price the assets or liabilities. The three levels of inputs used are as follows:

Level 1 — Quoted prices in active markets for identical assets or liabilities.

Level 2 — Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data.

Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. This includes certain pricing models, discounted cash flow methodologies and similar techniques that use significant unobservable inputs.

As of September 30, 2012 and 2013, the Company had assets and liabilities that fell under the scope of ASC 820. The fair value of the Company's warrant liability was determined by the Monte Carlo simulation method for the warrants issued in connection with the Company's August 2010 financing and by the Black-Scholes valuation model for the warrants issued in connection with the Company's May 2011 and June 2012 financings. The Monte Carlo simulation method is a generally accepted statistical method used to generate a defined number of stock price paths in order to develop a reasonable estimate of the range of future expected stock prices of the Company and its peer group and minimize standard error. The Black-Scholes valuation model takes into account, as of the valuation date, factors including the current exercise price, the expected life of the warrant, the current price of the underlying stock and its expected volatility, expected dividends on

the stock, and the risk-free interest rate for the term of the warrant. Accordingly, the Company's fair value measurements of its warrant liability is classified as a Level 3 input.

The fair value of the Company's financial assets and liabilities carried at fair value and measured on a recurring basis are as follows:

Description		Fair Value at September 30, 2013			Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Market Inputs (Level 2)		Significant Unobservable Inputs (Level 3)
Assets:
Cash and cash equivalents	$	39,781		$	39,781		—		—

Total	$	33,660		$	39,781	$	—	$	(6,121	)

Description		Fair Value at September 30, 2012			Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Market Inputs (Level 2)		Significant Unobservable Inputs (Level 3)
Assets:

Subtotal		(7,338	)		—		—		(7,338	)
Total	$	31,772		$	39,110	$	—	$	(7,338	)

The Company recognizes transfers into and out of the levels indicated above on the actual date of the event or change in circumstances that caused the transfer of change. All changes within Level 3 can be found in the following Level 3 reconciliation table:

Balance at September 30, 2009	$	—

The following table presents the Company's liabilities that are measured and recognized at fair value on a recurring basis classified under the appropriate level of the fair value hierarchy as of September 30, 2012 and September 30, 2013:

Description		Quoted Prices in Active Markets for identical Assets and Liabilities (Level 1)		Significant other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		Balance as of September 30, 2012		Quoted Prices in Active Markets for identical Assets and Liabilities (Level 1)		Significant other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		Balance as of September 30, 2013
Derivative liabilities related to Warrants	$	—	$	—	$	7,338	$	7,338	$	—	$	—	$	6,121	$	6,121

The following table sets forth a summary of changes in the fair value of the Company's Level 3 liabilities for the twelve months ended September 30, 2013 and September 30, 2012:

Description		Balance at September 30, 2011		Fair Value of warrants upon issuance		Unrealized (gains) or losses		Balance as of September 30, 2012		Fair Value of warrants upon issuance		Unrealized (gains) or losses			Balance as of September 30, 2013
Derivative liabilities related to Warrants	$	996	$	4,832	$	1,510	$	7,338	$	—	$	(1,217	)	$	6,121

The unrealized gains or losses on the derivative liabilities are recorded as a change in fair value of derivative liabilities in the Company's statement of operations. A financial instrument's level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. At each reporting period, the Company reviews the assets and liabilities that are subject to ASC Topic 815-40. At each reporting period, all assets and liabilities for which the fair value measurement is based on significant unobservable inputs or instruments which trade infrequently and therefore have little or no price transparency are classified as Level 3. The fair value of cash and cash equivalents as of September 30, 2013 and 2012 are $39,781 and $39,050, respectively, and the fair value of accounts payable as of September 30, 2013 and 2012 is $246 and $285, respectively, which approximates Net Book Value due to the short term.

4. Net Loss per Share

Net loss per share information is determined using the two-class method, which includes the weighted-average number of common shares outstanding during the period and other securities that participate in dividends ("participating securities"). The Company considers the outstanding warrants participating securities because they include rights to participate in dividends with the common stock on a one-for-one basis. In applying the two-class method, earnings are allocated to both common stock shares and warrants based on their respective weighted-average shares outstanding for the period. Since losses are not allocated to the participating securities, the two-class method results in the same loss per common share calculated using the basic method for the periods presented in these financial statements.

Basic and diluted net loss per share has been calculated by dividing net loss applicable to common stockholders by the weighted average number of common shares outstanding during the period. All potentially dilutive common shares have been excluded from the calculation of weighted average common shares outstanding since their inclusion would be anti-dilutive.

6. Related Party Transactions

The following is a description of material transactions, other than compensation arrangements, since the Company's incorporation on December 3, 2003 to which the Company has been a party and in which any of its directors, executive officers or persons who it knows held more than five percent of any class of capital stock, including their immediate family members who had or will have a direct or indirect material interest. The Company believes that the terms obtained or consideration paid or received, as applicable, in connection with the transactions described below were comparable to terms available or the amounts that would have been paid or received, as applicable, in arm's-length transactions.

Issuance of Series B Convertible Preferred Stock

On July 19, 2006, the Company issued and sold 38,071 shares of Series B convertible preferred stock (see Note 10) and a warrant to purchase 20,496 shares of common stock to its Chief Executive Officer in exchange for a $150 bonus that was earned by him during the calendar year ended December 31, 2005 but voluntarily deferred. At September 30, 2005, the Company accrued $113 of the bonus and the balance of $37 was expensed in fiscal 2006. The full amount of the accrued bonus was exchanged for Series B convertible preferred stock on July 19, 2006.

In connection with the issuance of the Series B convertible preferred stock, the Company retained MSI to serve as placement agent pursuant to an amendment to the Letter Agreement. MSI was paid (a) an aggregate commission of $350 from the sale of the Series B convertible preferred stock, (b) a warrant to purchase 126,903 shares of Series B convertible preferred stock and (c) a warrant to purchase 68,322 shares of common stock. On July 19, 2006, the Company also sold and issued to a director 12,690 shares of Series B convertible preferred stock and a warrant to purchase 6,832 shares of common stock. At the completion of the Series B preferred stock financing, the lead investor remitted the monies for its investment in the Series B Round net of offering-related expenses incurred by the investor group for which the Company was responsible. Total offering expenses were approximately $2,000, of which $1,470 was commissions for the placement of the offering. A director of the Company had arranged to pay for an investment in the Series B preferred stock financing (the "Investment") utilizing a portion of commissions due. Since the monies due for the commission were not received by the Company, the purchase price of the Investment could not be deducted from the monies received. The fair values of the warrants for common stock were $126 and $13 and were computed using the Black-Scholes valuation model using the following assumptions: term of 3.5 years; volatility rate of 50%; risk free rate of 5.05% and a dividend yield of 0.0%. The fair value of the warrants for preferred stock was $167 and was computed using the Black-Scholes valuation model using the following assumptions: term of 3.5 years; volatility rate of 50%; risk free rate of 4.70% and a dividend yield of 0.0%. These amounts were treated as cost of raising capital.

7. Commitments

Chief Executive Officer Employment Agreement

On March 30, 2010, the Company announced the appointment of Errol B. De Souza, Ph.D., as the Company's President, Chief Executive Officer and a Director. In connection with his appointment, Dr. De Souza signed an employment agreement, dated March 26, 2010, setting forth the terms of his employment.

Effective December 14, 2010, Dr. Solomon Steiner, the Company's former Chief Scientific Officer, retired from all his management positions with the Company. On the same date, the Company and Dr. Steiner executed a general release agreement. Dr. Steiner is therefore entitled to receive the severance benefits set forth in his employment agreement with the Company that were conditioned upon his signing the release. We recorded a charge of $1,360 for salary, bonus and benefits continuation for twenty-four months and an option acceleration modification charge of $7 in the three months ended December 31, 2010.

Purchase Commitments

The Company contracted with N.V. Organon, a global producer of RHI, to supply the Company with all of the RHI that the Company will need for testing and manufacturing of the Company's product candidates. In July 2011, the Company executed an amendment with N.V. Organon, which extends the term of the existing supply agreement to June 30, 2018 and releases the Company from any purchase commitments until the third calendar quarter of 2014. These commitments commence in the third calendar quarter of 2014 and extend through the second calendar quarter of 2018 for a total purchase commitment of approximately 160 kilograms of RHI. Both parties have the right to terminate the agreement with six months notice, with the Company having the option to purchase significant additional quantities if the supplier terminates the agreement prior to June 30, 2018. As of September 30, 2013, the Company had purchase commitments of approximately $18,787 associated with the signing of the renewed contract with N.V. Organon.

Commercial Supply Agreement with Bachem Americas

The Company has entered into a commercial supply agreement for the supply of glucagon with Bachem Americas, a supplier of glucagon. The Company is obligated to purchase certain quantities of glucagon pursuant to a rolling forecast submitted by the Company under this agreement.

Customization and Commercial Supply Agreement with Unilife Medical Solutions, Inc.

The Company has entered into a customization and commercial supply agreement with Unilife Medical Solutions, Inc. ("Unilife"), a wholly owned subsidiary of Unilife Corporation, a company which designs, develops and manufactures advanced drug delivery devices. The agreement obligates Unilife to develop and supply dual-chamber reconstitution devices to be used with the Company's glucagon rescue product candidate. The Company is obligated to make payments to Unilife on the achievement of certain development milestones, including a payment of $700 upon the delivery of devices meeting a target profile to be approved by both parties.

Other Commitments

The Company has entered into certain licensing and collaboration agreements for products currently under development. The Company may be obligated in future periods to make additional payments, which would become due and payable only upon the achievement of certain research and development, regulatory, and approval milestones. The specific timing of such milestones cannot be predicted and depend upon future discretionary research and clinical developments, as well as, regulatory agency actions. Further, under the terms of certain agreements the Company may be obligated to pay commercial milestones contingent upon the realization of sales revenues and sublicense revenues. Due to the long range nature of such commercial milestones, they are neither probable at this time nor predictable, and consequently are not considered contingent milestone payment amounts.

The Company files U.S. federal and state tax returns and has determined that its major tax jurisdictions are the United States and Connecticut. The tax years through 2011 remain open due to net operating loss and are subject to examination by the appropriate governmental agencies in the United States and Connecticut carry-forwards.

As of September 30, 2013, the Company had net operating loss ("NOL") carry-forwards of approximately $57,628 (net of Section 382 limitation discussed below) for U.S. federal tax purposes and $112,240 for state tax purposes. These loss carry-forwards expire between 2024 and 2032. To the extent these net operating loss carry-forwards are available, the Company intends to use them to reduce the corporate income tax liability associated with its operations.

(In thousands, except share and per share amounts)

The ability of the Company to utilize its NOL carry-forwards to reduce future taxable income is subject to various limitations under the Internal Revenue Code Section 382 ("Section 382"). The utilization of such carry-forwards may be limited upon the occurrence of certain ownership changes, including the purchase or sale of stock by 5% shareholders and the offering of stock by the Company during any three-year period resulting in an aggregate change of more than 50% in the beneficial ownership of the Company. In the event of an ownership change, Section 382 imposes an annual limitation on the amount of a Company's taxable income that can be offset by these carry-forwards. As of September 30, 2011, the Company completed a study of the impact of Section 382 limitation on future payments and determined that the statutory provisions limited the Company's ability to realize future tax benefits. Accordingly, the Company decreased federal net operating loss carry-forwards by approximately $55,929 and federal research and development credit carry-forwards by $1,817.

The Company also has state research and development credit carry-forwards of approximately $339, which expire commencing in fiscal 2022.

The major components of deferred tax assets and valuation allowances and deferred tax liabilities at September 30, 2012 and 2013 are as follows:

		September 30,
		2012			2013
Deferred Tax Assets
Net operating losses	$	24,969		$	25,149
Capitalized expense		21,907			28,913
Research and development credits		477			224
Depreciation of fixed assets		51			445
Other		453			283
Total deferred tax asset		47,857			55,014
Valuation Allowance		(47,857	)		(55,014	)
Net Deferred Tax Assets	$	—		$	—

As the Company has not yet achieved profitable operation, management does not believe that it is more likely than not that the tax benefits as of September 30, 2013 will be realized and therefore has recorded a valuation allowance against its deferred tax assets.

9. Financings

June 2013 Public Offering

On June 24, 2013, the Company completed an underwritten public offering of 4,482,760 shares of its common stock at a price to the public of $4.35 per share. On July 22, 2013, the Company issued 236,007 additional shares of common stock, at the public offering price of $4.35 per share, in connection with the underwriters' exercise of a portion of their over-allotment option. The Company received net proceeds from this offering, after deducting underwriting discounts, commissions and expenses, of $19.2 million.

June 2012 Private Placement

In June 2012, the Company completed a private placement (the "2012 Private Placement") of an aggregate of 4,250,020 shares of the Company's common stock, 3,605,607 shares of the Company's Series B preferred stock and warrants to purchase an aggregate of 2,749,469 shares of common stock at an exercise price of $2.66 per share. For each unit, consisting of either a share of common stock or Series B preferred stock and a warrant to purchase 0.35 of a share of common stock, the purchasers in the June 2012 Private Placement paid a negotiated price of $2.355. The warrants are immediately exercisable and will expire on

Notes to Financial Statements — (Continued)

(In thousands, except share and per share amounts)

June 26, 2017, five years from the original issuance date of June 27, 2012. The Company received net proceeds, after deducting placement agents' fees and other transaction expenses, of approximately $17,100 from the 2012 Private Placement.

Each share of Series B preferred stock is convertible into one share of the Company's common stock at any time at the option of the holder, except that the securities purchase agreement that the Company entered into in connection with the 2012 Private Placement (the "Securities Purchase Agreement") provides that a holder will be prohibited from converting shares of Series B preferred stock into shares of common stock if, as a result of such conversion, such holder, together with its affiliates, would beneficially own more than 9.98% of the total number of shares of common stock then issued and outstanding. In the event of the Company's liquidation, dissolution or winding up, holders of the Series B preferred stock will receive a payment equal to $0.01 per share of Series B preferred stock before any proceeds are distributed to the holders of common stock. After the payment of this preferential amount, and subject to the rights of holders of any class or series of capital stock specifically ranking by its terms senior to the Series B preferred stock, holders of Series B preferred stock and holders of the Company's Series A preferred stock will participate ratably in the distribution of any remaining assets with the common stock and any other class or series of capital stock that participates with the common stock in such distributions. Shares of Series B preferred stock will generally have no voting rights, except as required by law and except that the consent of the holders of a majority of the outstanding Series B preferred stock will be required to amend the terms of the Series B preferred stock. Holders of Series B preferred stock are entitled to receive, and the Company is required to pay, dividends on shares of the Series B preferred stock equal (on an as-if-converted-to-common-stock basis) to and in the same form as dividends (other than dividends in the form of common stock) actually paid on shares of the common stock when, as and if such dividends (other than dividends in the form of common stock) are paid on shares of the common stock.

As required by the Securities Purchase Agreement, the Company filed a Registration Statement on Form S-3 (the "Registration Statement") with the Securities and Exchange Commission (the "SEC") on July 27, 2012, which was within 30 days after the closing of the 2012 Private Placement. The Registration Statement, which was declared effective on August 13, 2012, registers the resale of the shares of common stock and Series B preferred stock issued and sold in the 2012 Private Placement, the shares of common stock issuable upon conversion of the Series B preferred stock issued and sold in the 2012 Private Placement, and the shares of common stock issuable upon exercise of the warrants issued and sold in the 2012 Private Placement. Pursuant to the terms of the Securities Purchase Agreement, the Company agreed to pay liquidated damages to the purchasers in the 2012 Private Placement if, after effectiveness of the Registration Statement and subject to certain specified exceptions, the Company suspends the use of the Registration Statement or the Registration Statement ceases to remain continuously effective as to all the securities for which it is required to be effective (each such event, a "Registration Default"). Subject to specified exceptions, for each 30-day period or portion thereof during which a Registration Default remains uncured, the Company is obligated to pay liquidated damages to each purchaser in cash in an amount equal to 1.0% of the aggregate purchase price paid by each such purchaser in the 2012 Private Placement, up to a maximum of 8.0% of such aggregate purchase price. As of the date of these financial statements, the Company does not believe that it is probable that it will be obligated to pay any such liquidated damages. Accordingly, the Company has not established an accrual for liquidated damages.

In the event that the Company enters into a merger or change of control transaction, the holders of the warrants issued in the 2012 Private Placement will be entitled to receive consideration as if they had exercised the warrants immediately prior to such transaction, or they may require the Company to purchase the unexercised warrants at the Black-Scholes value (as defined in the warrant) of the warrant on the date of such transaction. The holders have up to 30 days following any such transaction to exercise this right. As a result of this provision, the Company recognizes the warrants as liabilities at their fair value on each reporting date.

During the year ended September 30, 2013, the Company recorded an adjustment to fair value of common stock warrant liability of $675, within Other (income) expense, to reflect the decrease in the

The following summarizes the changes in value of the warrant liability from the date of issuance through September 30, 2013:

May 2011 Registered Direct Offering

In May 2011, the Company completed a registered direct offering of an aggregate of 3,018,736 shares of the Company's common stock, 453,486 shares of the Company's Series A preferred stock and warrants to purchase 2,256,929 shares of the Company's common stock. The shares and warrants were sold in units consisting of (i) one share of common stock and (ii) one warrant to purchase 0.1625 of a share of common stock, at an exercise price of $9.92 per share of the Company's common stock. However, one investor also purchased units consisting of one share of Series A preferred stock and a warrant to purchase 0.1625 of a share of common stock. No fractional warrants were issued. Each unit was sold at a price of $8.64 per unit. These units were not issued or certificated. The shares and warrants were immediately separated. The warrants will expire on May 17, 2016, five years from the issuance date of May 18, 2011. The Company received net proceeds, after deducting placement agent fees and other offering expenses, of approximately $28.0 million from this financing.

Each share of Series A preferred stock is convertible into one quarter of a share of the Company's common stock at any time at the option of the holder, provided that the holder will be prohibited from converting the shares of Series A preferred stock into shares of the Company's common stock if, as a result of such conversion, the holder, together with its affiliates, would beneficially own more than 9.98% of the total number of shares of the Company's common stock then issued and outstanding. In the event of the Company's liquidation, dissolution or winding up, holders of the Series A preferred stock will receive a payment equal to $0.01 per share of Series A preferred stock before any proceeds are distributed to the holders of the Company's common stock. After the payment of this preferential amount, and subject to the rights of holders of any class or series of capital stock specifically ranking by its terms senior to the Series A preferred stock, holders of Series A preferred stock will participate ratably in the distribution of any remaining assets with the Company's common stock and any other class or series of capital stock that participates with the common stock in such distributions. Shares of Series A preferred stock will generally have no voting rights, except as required by law and except that the consent of the holders of a majority of the outstanding Series A preferred stock will be required to amend the terms of the Series A preferred stock. The Series A preferred stock will not be entitled to receive any dividends, unless and until specifically declared by the Company's board of directors.

In the event that the Company enters into a merger or change of control transaction, the holders of the warrants issued in the May 2011 financing will be entitled to receive consideration as if they had exercised the warrant immediately prior to such transaction, or they may require the Company to purchase the unexercised warrants at the Black-Scholes value (as defined in the warrant) of the warrant on the date of such transaction. As per the terms of the warrants, the holders have up to 30 days following any such transaction to exercise this right. As a result of this provision, the Company recognizes the warrants as liabilities at their fair value on each reporting date.

The Company's warrant liability is marked-to-market each reporting period with the change in fair value recorded as a gain or loss within Other Expense ("Adjustment to fair value of common stock warrant liability"), until the warrants are exercised, expire or other facts and circumstances lead the warrant liability to be reclassified as an equity instrument. Because the warrants issued in the May 2011 financing do not contain a re-pricing provision, the Company is using the Black-Scholes valuation model to estimate the fair value of the warrants. Using this model, the Company recorded an initial warrant liability of $9,438 as of May 18, 2011 (the warrant issuance date). The significant assumptions of the model were warrants and common stock outstanding, remaining terms of the warrants, the per stock price of $2.06, a risk-free rate of 1.89% and expected volatility rate of 75%.

During the year ended September 30, 2013, the Company recorded an adjustment to fair value of common stock warrant liability of $542, within Other (income) expense, to reflect the decrease in the valuation of the warrants from September 30, 2012 to September 30, 2013. At September 30, 2013, the fair value of the warrant liability determined utilizing the Black-Scholes valuation model was approximately $1,163.The following summarizes the changes in value of the warrant liability from the date of issuance through September 30, 2013:

August 2010 Registered Direct Offering

In August 2010, the Company sold to two institutional investors an aggregate of 599,550 units, with each unit consisting of (i) one share of common stock and (ii) one warrant to purchase one share of common stock, for a purchase price of $15.72 per unit. These units were not issued or certificated. The shares and warrants were immediately separated and the Company issued 599,550 shares of its common stock and warrants to purchase an additional 599,550 shares of the Company's common stock. This financing resulted in net proceeds of $8,700.

In August 2011, one investor exercised 10,550 warrants, at $4.70 per share, and the Company received proceeds totaling approximately $50. Subsequently, on December 1, 2011 the remaining 589,000 warrants expired unexercised.

Fair Value Assumptions Used in Accounting for Warrant Liability

The Company has determined its warrant liability to be a Level 3 fair value measurement and used the Black Scholes valuation model to calculate the fair value for the fiscal year ended September 30, 2012 and 2013.

At the measurement date, the Company estimated the fair value for the June 2012 warrants using the Black-Scholes valuation model using the following assumptions:

		September 30, 2012		September 30, 2013
June 2012 Financing
Stock price	$	2.97		$3.15
Exercise price	$	2.66		$2.66

Expected remaining term		4.74 years		3.74 years
Expected volatility		98	%	82%
Dividend yield		0	%	0%
Warrants outstanding June 2012 registered direct		2,749,469		2,749,469

The Company estimated the fair value for the May 2011 warrants using the Black-Scholes valuation model at the measurement dates of September 30, 2013 and 2012, respectively using the following assumptions:

	September 30, 2012	September 30, 2013
May 2011 Financing
Stock price	$2.97	$3.15
Exercise price	$9.92	$9.92
Risk-free interest rate	0.31%	0.63%
Expected remaining term	3.63 years	2.63 years
Expected volatility	82%	77%
Dividend yield	0%	0%
Warrants outstanding May 2011 registered direct	2,256,929	2,256,929

Risk-Free Interest Rate. This is the United States Treasury rate for the measurement date having a term equal to the expected remaining term of the warrant. An increase in the risk-free interest rate will increase the fair value and the associated derivative liability.

Expected Remaining Term. This is the period of time over which the warrant is expected to remain outstanding and is based on management's estimate, taking into consideration the remaining contractual life.

Expected Volatility. This is a measure of the amount by which the stock price has fluctuated or is expected to fluctuate. Since the Company's stock has been traded for the expected remaining term of the warrants, the Company uses its own historic volatility over the retrospective period corresponding to the expected remaining term of the warrants on the measurement date. Extra weighting is attached to those companies most similar in terms of size and business activity. An increase in the expected volatility will increase the fair value and the associated derivative liability.

Dividend Yield. The Company has not made any dividend payments nor does it have plans to pay dividends in the foreseeable future. An increase in the dividend yield will decrease the fair value and the associated derivative liability.

Participating Securities

If at any time the Company grants, issues or sells securities or other property to holders of any class of common stock the holders of the warrants are entitled to also acquire those same securities as if they held the number of shares of common stock acquirable upon complete exercise of the warrants.

As such, given that the warrant holders will participate fully on any dividends or dividend equivalents, the Company determined that the warrants are participating securities and therefore are subject to ASC 260-10-55 earnings per share. These securities were excluded for the years ended September 30, 2013, 2012 and 2011 earnings per share calculation since their inclusion would be anti-dilutive.

As of September 30, 2013, the Company had the following warrants outstanding:

(i) May 2011 financing —

 (a) warrants to purchase 2,256,929 shares of the Company's common stock with an exercise price of $9.92 per share

(ii) June 2012 financing —

(a) warrants to purchase 2,066,969 shares of the Company's common stock with an exercise price of $2.66 per share and

(b) Series B convertible preferred stock — warrants to purchase 682,500 shares of the Company's common stock with an exercise price of $2.66 per share.

Preferred Stock

The Company is authorized to issue up to 50,000,000 shares of preferred stock, having a par value of $0.01 per share. The Company's preferred stock may be issued in one or more series, the terms of which may be determined at the time of issuance by the Company's Board of Directors, without further action by stockholders, and may include voting rights (including the right to vote as a series on particular matters), preferences as to dividends and liquidation and conversion, redemption rights and sinking fund provisions. The issuance of preferred stock could reduce the rights, including voting rights, of the holders of common stock and, therefore, could reduce the value of the common stock. In particular, specific rights granted to holders of preferred stock could be used to restrict the Company's ability to merge with or sell the Company's assets to a third party, thereby preserving control of the Company by existing management.

Series A Preferred Stock May 2011 Financing

As part of the May 2011 registered direct offering, the Company issued 1,813,944 shares of the Company's Series A preferred stock to one investor. The investor purchased units consisting of one share of Series A preferred stock and a warrant to purchase 0.1625 of a share of common stock. No fractional warrants were issued. Each unit was at a price of $8.84 per unit.

Each share of Series A preferred stock is convertible into 0.25 of a share of the Company's common stock at any time at the option of the holder, provided that the holder will be prohibited from converting the shares of series A preferred stock into shares of the Company's common stock if, as a result of such conversion, the holder, together with its affiliates, would beneficially own more than 9.98% of the total number of shares of the Company's common stock then issued and outstanding. In the event of the Company's liquidation, dissolution or winding up, holders of the Series A preferred stock will receive a payment equal to $0.01 per share of Series A preferred stock before any proceeds are distributed to the holders of the Company's common stock. After the payment of this preferential amount, and subject to the rights of holders of any class or series of capital stock specifically ranking by its terms senior to the Series A preferred stock, holders of Series A preferred stock and holders of the Company's Series B stock will participate ratably in the distribution of any remaining assets with the Company's common stock and any other class or series of capital stock that participates with the common stock in such distributions. Shares of Series A preferred stock will generally have no voting rights, except as required by law and except that the consent of the holders of a majority of the outstanding Series A preferred stock will be required to amend the terms of the Series A preferred stock. The Series A preferred stock will not be entitled to receive any dividends, unless and until specifically declared by the Company's board of directors.

In August 2013, 1,813,944 shares of the Company's Series A Convertible Preferred Stock were converted into 453,483 shares of common stock.

Series A Preferred Stock July 2005 Private Placement

(In thousands, except share and per share amounts)

September 30, 2007. In addition, in connection with the July 2006 private placement, the Company issued warrants to purchase shares of the Company's series A preferred stock. All such warrants were expired as of September 30, 2012.

In connection with the Series A preferred stock issuance, the Company entered into a registration rights agreement with the purchasers of its stock, which provided, among other things, for liquidated damages if the Company were initially unable to register and obtain an effective registration of the securities within the allotted time. The stockholders could not demand registration until one hundred and eighty (180) days after the Company had effected a qualified initial public offering. The penalties were (i) one and three quarters (1¾%) percent of the aggregate number of shares of underlying common stock for each month, or part thereof, after a ninety (90) day period that a registration statement was not filed with the SEC or (ii) one (1%) percent of the aggregate number of shares of underlying common stock for each month if the forgoing filed registration statement was not declared effective by the SEC within one hundred and twenty (120) days.

Each share of Series A preferred stock was automatically converted into a number of shares of common stock equal to the quotient of $3.54 divided by $1.00 immediately subsequent to the date of the initial public offering.

As part of the compensation agreement, the placement agent received 69,875 Series A warrants. Each warrant consists of the right to purchase one share of fully paid and non-assessable common stock for a period of seven years which expired on July 12, 2012.

Series B Preferred Stock June 2012 Private Placement

In June 2012, the Company completed a private placement of an aggregate of 4,250,020 shares of the Company's common stock, 3,605,607 shares of the Company's Series B Convertible Preferred Stock and warrants to purchase an aggregate of 2,749,469 shares of common stock at an exercise price of $2.66 per share. For each unit consisting of either a share of common stock or Series B preferred stock and a warrant to purchase 0.35 of a share of common stock, the purchasers in the June 2012 Private Placement paid a negotiated price of $2.355.

Each share of Series B preferred stock is convertible into one share of the Company's common stock at any time at the option of the holder, except that the securities purchase agreement that the Company entered into in connection with the 2012 Private Placement (the "Securities Purchase Agreement") provides that a holder will be prohibited from converting shares of Series B preferred stock into shares of common stock if, as a result of such conversion, such holder, together with its affiliates, would beneficially own more than 9.98% of the total number of shares of common stock then issued and outstanding. In the event of the Company's liquidation, dissolution or winding up, holders of the Series B preferred stock will receive a payment equal to $0.01 per share of Series B preferred stock before any proceeds are distributed to the holders of common stock. After the payment of this preferential amount, and subject to the rights of holders of any class or series of capital stock specifically ranking by its terms senior to the Series B preferred stock, holders of Series B preferred stock and holders of the Company's Series A preferred stock will participate ratably in the distribution of any remaining assets with the common stock and any other class or series of capital stock that participates with the common stock in such distributions. Shares of Series B preferred stock will generally have no voting rights, except as required by law and except that the consent of the holders of a majority of the outstanding Series B preferred stock will be required to amend the terms of the Series B preferred stock. Holders of Series B preferred stock are entitled to receive, and the Company is required to pay, dividends on shares of the Series B preferred stock equal (on an as-if-converted-to-common-stock basis) to and in the same form as dividends (other than dividends in the form of common stock) actually paid on shares of the common stock when, as and if such dividends (other than dividends in the form of common stock) are paid on shares of the common stock.

As required by the Securities Purchase Agreement, the Company filed a Registration Statement on Form S-3 (the "Registration Statement") with the Securities and Exchange Commission (the "SEC") on July 27,

F-29

Biodel Inc.

Notes to Financial Statements — (Continued)

(In thousands, except share and per share amounts)

2012, which was within 30 days after the closing of the 2012 Private Placement. The Registration Statement, which was declared effective on August 13, 2012, registers the resale of the shares of common stock and Series B preferred stock issued and sold in the 2012 Private Placement, the shares of common stock issuable upon conversion of the Series B preferred stock issued and sold in the 2012 Private Placement, and the shares of common stock issuable upon exercise of the warrants issued and sold in the 2012 Private Placement. Pursuant to the terms of the Securities Purchase Agreement, the Company agreed to pay liquidated damages to the purchasers in the 2012 Private Placement if, after effectiveness of the Registration Statement and subject to certain specified exceptions, the Company suspends the use of the Registration Statement or the Registration Statement ceases to remain continuously effective as to all the securities for which it is required to be effective (each such event, a "Registration Default"). Subject to specified exceptions, for each 30-day period or portion thereof during which a Registration Default remains uncured, the Company is obligated to pay liquidated damages to each purchaser in cash in an amount equal to 1.0% of the aggregate purchase price paid by each such purchaser in the 2012 Private Placement, up to a maximum of 8.0% of such aggregate purchase price. As of the date of these financial statements, the Company does not believe that it is probable that it will be obligated to pay any such liquidated damages. Accordingly, the Company has not established an accrual for liquidated damages.

In June 2013, 176,964 shares of the Company's Series B Convertible Preferred Stock were converted into an equal number of shares of common stock. In September 2013, an additional 1,478,643 shares of the Company's Series B Convertible Preferred Stock were converted into an equal number of shares of common stock.

Series B Preferred Stock July 2006 Private Placement

In July 2006, the Company authorized 6,500,000 shares of its Series B preferred stock and completed a private placement of 5,380,711 of these shares, of which 0 shares were issued and outstanding as of September 30, 2007. In addition, in connection with the July 2006 private placement the Company issued warrants to purchase shares of the Company's Series B preferred stock. All such warrants were expired as of September 30, 2012.

As a result of the conversion option, the Company considered the features contained in the Series B preferred stock to ascertain whether the shares contained a beneficial conversion feature and determined that the issuance of the Series B preferred stock resulted in a beneficial conversion feature in the amount of $603.

Shares Reserved for Future Issuance

As of September 30, 2013, the Company reserved shares of common stock for future issuance as follows:

2010 stock incentive plan	5,290,739
2005 employee stock purchase plan	475,000
Common shares issuable upon conversion of Series B Preferred Stock	1,950,000

Warrants issued in connection with June 2012 private placement	2,749,469
Total	12,722,137

2004 Stock Incentive Plan

The Company established the 2004 Stock Incentive Plan on October 1, 2004 (the "Plan"), as amended in March 2007, and subsequently replaced by the 2010 Stock Incentive Plan. The Plan provides for the granting of shares of common stock or securities convertible into or exercisable for shares of common stock, including stock options ("Incentive Stock Options") to directors, employees, consultants and advisors of or to the

F-30

(In thousands, except share and per share amounts)

Company. Incentive Stock Options can be awarded only to persons who are employees of the Company at the time of the grant. Stock options are exercisable at the conclusion of the vesting period. Employees can exercise their vested shares up to 90 days after termination of services. No awards may be granted under the Plan after the effective date of the 2010 Plan.

The Plan is be administered by either the Board of Directors of the Company or a Committee thereof, which determines the terms and conditions of the awards granted under the Plan, including the recipient of the award, the nature of the award, the exercise price of the award, the number of shares subject to the award and the exercisability thereof.

Non-employee directors are not entitled to receive awards other than the non-qualified stock options the plan directs be issued to non-employee directors.

2010 Stock Incentive Plan

In March 2013, the stockholders of the Company approved the amended and restated 2010 Stock Incentive Plan (the "2010 Plan"). Up to 3,750,000 shares of the Company's common stock may be issued pursuant to awards granted under the 2010 Plan, plus 1,540,739 shares of common stock underlying already outstanding awards under the Company's prior plans. As of September 30, 2013, the Company had 1,951,347 shares of common stock subject to outstanding awards. The contractual life of options granted under the 2010 Plan may not exceed seven years. The 2010 Plan uses a "fungible share" concept under which any awards that are not a full-value award will be counted against the share limit as one (1) share for each share of common stock and any award that is a full-value award will be counted against the share limit as 1.5 shares for each one share of common stock. The Company has not made any new awards under any prior equity plans after March 2, 2010 — the effective date the 2010 Plan was approved by the Company's stockholders. The 2010 Plan replaces the 2004 Stock Incentive Plan and 2005 Non-Employee Directors Stock Option Plan.

2005 Employee Stock Purchase Plan

The Company's 2005 Employee Stock Purchase Plan, or the Purchase Plan, was adopted by its Board of Directors and approved by its stockholders on March 20, 2007. The Purchase Plan became effective upon the closing of the Company's initial public offering. The Purchase Plan is intended to qualify as an employee stock purchase plan within the meaning of Section 423 of the Code.

Under the Purchase Plan, eligible employees may contribute up to 15% of their eligible earnings for the period of that offering withheld for the purchase of common stock under the Purchase Plan. The employee's purchase price is equal to the lower of: 85% of the fair market value per share on the start date of the offering period in which the employee is enrolled or 85% of the fair market value per share on the semi-annual purchase date. The Purchase Plan imposes a limitation upon a participant's right to acquire common stock if immediately after the purchase, the employee would own 5% or more of the total combined voting power or value of the Company's common stock or of any of its affiliates not eligible to participate in the Purchase Plan. The Purchase Plan provides for an automatic rollover when the purchase price for a new offering period is lower than previously established purchase price(s). The Purchase Plan also provides for a one-time election that allows an employee the opportunity to enroll into a new offering period when the new offering is higher than their current offering price. This election must be made within 30 days from the start of a new offering period. Offering periods are twenty-seven months in length. The compensation cost in connection with the plan for the years ended September 30, 2011, 2012 and 2013 was $53, $16, and $5 respectively.

An aggregate of 475,000 shares of common stock are reserved for issuance pursuant to purchase rights to be granted to the Company's eligible employees under the Purchase Plan. The Purchase Plan shares are replenished annually on the first day of each fiscal year by virtue of an evergreen provision. The provision allows for share replenishment equal to the lesser of 1% of the total number of shares outstanding on that date or 25,000 shares. As of September 30, 2011, 2012 and 2013, a total of 341,097, 355,321 and 366,926 shares,

respectively, were reserved and available for issuance under this plan. For the years ended September 30, 2011, 2012 and 2013, the Company issued a total of, 83,903, 94,679 and 108,074 shares, respectively, under the Purchase Plan.

2005 Non-Employee Directors' Stock Option Plan

The Company's 2005 Non-Employee Directors' Stock Option Plan (the "Directors' Plan") was adopted by its Board of Directors and approved by its stockholders on March 20, 2007 and subsequently replaced with the 2010 Stock Incentive Plan. The Directors' Plan became effective upon the closing of the Company's initial public offering. An aggregate of 125,000 shares of common stock were reserved for issuance under the Directors' Plan. Upon the effective date of the registration statement in connection with the Company's initial public offering, each of its non-employee directors automatically received an initial option to purchase 6,250 shares of common stock. Upon appointment, non-employee directors receive a one-time grant of an option to purchase 6,250 shares of common stock. Annually, non-employee directors receive an option to purchase 5,000 shares of common stock. Effective March 3, 2009, these shares vest pro rata over one year. However, in the event a non-employee director has not served since the date of the preceding annual meeting of stockholders, that director will receive an annual grant that has been reduced pro rata for each full quarter prior to the date of grant during which such person did not serve as a non-employee director.

The fair value per share is being recognized as compensation expense over the applicable vesting period. The fair value per share for awards granted as of December 31, 2008 through September 30, 2012 was calculated using the Black-Scholes valuation model.

The fair value of the common stock for the grants from December 23, 2004 through November 1, 2006 was determined using a retrospective valuation. The fair value of the common stock for the grants during December 2006 and subsequently was determined contemporaneously with the grants.

Restricted Stock Units

The Company grants restricted stock units ("RSUs") to executive officers and employees pursuant to the 2010 Plan from time to time. There is no direct cost to the recipients of RSUs, except for any applicable taxes.

On March 8, 2012, the Company's stockholders approved an amendment to the 2010 Plan to increase the number of shares of common stock authorized for issuance thereunder solely for the purpose of allowing the Company to issue an 191,719 restricted stock units to certain of the Company's employees in place of an aggregate of $823 in discretionary cash bonuses in connection with the fiscal year ended September 30, 2011 (the "2011 Bonus RSUs"). The 2011 Bonus RSUs vested and were distributed on September 30, 2012. The Company had previously accrued and expensed the $823 in the fiscal year ended September 30, 2011. The 2011 Bonus RSUs vested in full and was distributed on September 30, 2012. Since the total fair value of the 2011 Bonus RSUs did not exceed the discretionary aggregate cash bonus value of $823, the Company did not record any additional stock-based compensation expense in the year ended September 30, 2012. The accrued bonus liability was settled in March 2012 and, accordingly, the liability, net of taxes, in the amount of $582 was reversed into additional paid-in-capital. Each RSU award that was granted in December 2010 to our executive officers and employees represents one share of common stock and each award vests annually over three years, with fifty percent vesting on the first anniversary of the date of grant and the remainder vesting in two equal installments on each anniversary thereafter. Each year following the annual vesting date, between January 1st and March 15th, the Company will issue common stock for each vested RSU. During the period when the RSU is vested but not distributed, the RSUs cannot be transferred and the grantee has no voting rights. If the Company declares a dividend, RSU recipients will receive payment based upon the percentage of RSUs that have vested prior to the date of declaration. The costs of the awards, determined as the fair market value of the shares on the grant date, are expensed per the vesting schedule outlined in the award. For example, the December 2010 RSU awards vest over three years and are expensed 50% the first year and 25% the next two years; whereas, the December 2009 RSU awards are expensed ratably over the four year vesting period.

Based on historical experience of option cancellations, the Company has estimated an annualized forfeiture rate of 7.5% for employee RSUs. Forfeiture rates will be adjusted over the requisite service period when actual forfeitures differ, or are expected to differ, from the estimate. As of September 30, 2013, the executives, the board of directors and employees had 374,925 vested and distributed RSUs.

The stock-based compensation expense associated with the RSUs has been recorded in the statement of operations and in additional paid-in-capital on the balance sheets is as follows:

		September 30,
		2011		2012		2013
Stock compensation expense — RSUs	$	585	$	1,202	$	363

At September 30, 2013, there was $50 of total unrecognized stock-based compensation expense related to RSU awards granted under the 2004 Stock Incentive Plan and the 2010 Plan. This expense is expected to be recognized over the remaining vesting periods up to four years.

11. Employee Benefit Plan

Effective January 1, 2006, the Company established a 401(k) plan covering substantially all employees.

12. Reverse Stock Splits

On June 11, 2012, the Company amended its certificate of incorporation in order to effect a one-for-four reverse split of its outstanding common stock and to fix on a post-split basis the number of authorized shares of its common stock at 25,000,000 (reduced from 100,000,000 authorized shares). As a result of the 2012 reverse stock split, each share of Company common stock outstanding at the effective time was automatically changed into one-quarter of a share of common stock. No fractional shares were issued in connection with the 2012 reverse stock split, and cash of $0.3 was paid in lieu of fractional shares. Also as a result of the 2012 reverse stock split, the number of shares of common stock subject to outstanding options, RSUs and warrants issued by the Company and the number of shares reserved for future issuance under the Company's stock plans have been reduced by a factor of four. There was no alteration to the par value of the common stock or any modification of the voting rights or other terms thereof. All references in these financial statements and accompanying notes to units of common stock or per share amounts are reflective of the 2012 reverse stock split for all periods reported. Additionally, on November 1, 2012 as a result of a special stockholders meeting, authorized shares was increased from 25,000,000 to 62,500,000.

On April 12, 2007, the Company completed a 0.7085 for one (0.7085:1) reverse stock split rounding all fractional shares down to the next full share. Stockholders received cash in lieu of fractional shares. After the 2007 reverse split, there were 2,000,957 shares of common stock outstanding. The 2007 reverse split did not
