关键财务数据
| 指标 | 2026年第三季度业绩 | 变化或背景 |
|---|---|---|
| ARCALYST收入 | 2.86亿美元 | 同比增长58%;环比增加4250万美元 |
| ARCALYST合作利润 | 2.116亿美元 | 同比增长67% |
| 营业利润 | 5420万美元 | 同比大幅增长 |
| 净利润 | 4730万美元 | 同比大幅增长 |
| 季度末现金余额 | 5.688亿美元 | 第三季度创造净现金约4300万美元 |
运营费用增加的原因在于:与ARCALYST收入挂钩的售出商品成本和合作费用上升、KPL-387研发支出增加,以及为支持商业化而扩大的销售、一般及行政费用(SG&A)投入。
业务与经营表现
ARCALYST仍是Kiniksa的主要增长驱动力。其23%的渗透率适用于每年约14,000名经历两次或以上复发的患者。管理层还确定了每年约26,000名首次复发的患者群体。
截至第三季度末,开方医生基数达到约5,450人,较上一季度增加约450人。其中约30%为重复开方医生,该群体在季度内增加了约170人。根据公司的历史市场调查,大约80%的处方来自多次复发的患者,20%来自首次复发的患者。
管理层表示,医生正越来越多地考虑在病程更早期使用ARCALYST,包括在非甾体抗炎药(NSAIDs)和秋水仙碱之后、糖皮质激素之前。受访医生中有约50%支持这一方法,是2025年美国心脏病学会简明临床指南发布前三年记录水平的两倍。
Kiniksa正利用AI和机器学习精准定位医生与患者。其“Heart’s Home”直接面向消费者(DTC)宣传活动使ARCALYST网站的流量较活动前增长了12倍,互动会话量增长了8倍。在看到该广告的患者中,约有55%强烈赞同自己受其推动去与医疗服务提供者讨论ARCALYST。
KPL-387的关键III期研究继续通过全球临床中心网络招募患者并给药。KPL-387正在被开发为一种每月一次、300毫克的皮下注射疗法,用于治疗复发性心包炎。
另一项向单药治疗过渡的研究正在评估患者如何从NSAIDs、秋水仙碱、糖皮质激素或IL-1通路抑制剂过渡到KPL-387。该研究包含16周的主要终点期,旨在为剂量和给药说明提供依据。
管理层引用的目标产品特征研究显示,约75%的患者相较于现有商业化疗法或其他在研疗法,更青睐KPL-387潜在的每月一次液体制剂。此外,受访的专业医疗人员中有92%表示很有可能开出符合该目标特征的处方。这些发现反映的是市场调研结果而非临床疗效数据。
管理层指引
| 2026年指引 | 预期区间 | 管理层点评 |
|---|---|---|
| ARCALYST销售额 | 10.45亿-10.50亿美元 | 因接纳度持续增长而上调 |
| 研发费用 | 1.60亿-1.70亿美元 | 包含KPL-387和KPL-1161的研发,以及第四季度KPL-387大额商业化前生产成本 |
| 销售、一般及行政费用(SG&A) | 2.70亿-2.80亿美元 | 支持人员扩充、推广活动、疾病认知提升和针对性拓展 |
管理层预计KPL-387的III期数据将于2027年下半年公布,并认为有可能在2028-2029年实现商业化上市。Kiniksa还预计KPL-1161将在2026年底前进入I期试验。
风险与关注事项
- KPL-387的疗效仍需在正在进行的关键III期试验中加以证实。研发时间表及2028-2029年的潜在上市计划仍属于管理层的预期。
- KPL-387的商业潜力取决于临床数据,包括其关键研究和过渡研究的结果。
- ARCALYST进一步提高渗透率需要触及地理分布分散的复发性心包炎患者群体,并持续投资于医生教育、一线执行和针对性消费者推广。
- 随着Kiniksa推进其研发管线并扩大ARCALYST商业化,研发与销售及管理费用(SG&A)支出正在增加。
分析师问答亮点
- KPL-387时间表:管理层将对2027年下半年数据目标的信心归因于积极的招募、患者给药、全球试验网络以及与研究人员的直接沟通。
- ARCALYST渗透率:管理层表示,尚未观察到患者人口统计特征或疾病严重程度发生实质性变化。剩余的市场机会既包括多次复发的患者,也包括首次复发的患者。
- 商业化支出:该公司将其DTC和一线业务投资描述为精准定向而非广泛铺开,支出集中于潜在的复发性心包炎患者及相关医疗专业人员。
- KPL-387用药转换策略:过渡研究旨在为医生提供实用指导,帮助患者从口服疗法、糖皮质激素或其他IL-1抑制剂转换为每月一次的KPL-387单药治疗。
- KPL-1161:管理层表示,其潜在的每季度给药一次的特征可支持慢性或终生疾病场景,同时眼下的重点仍是启动I期试验。
- 资本配置:Kiniksa继续评估内部和外部业务拓展机会,但管理层表示其现有的商业化业务和管线为并购交易设定了较高的门槛。

Operator
Thank you for standing by, and welcome to the Kiniksa Pharmaceuticals Third Quarter 2026 Earnings Conference Call. [Operator Instructions] As a reminder, today's program is being recorded.
And now I'd like to introduce your host for today's program, Jonathan Kirshenbaum, Investor Relations. Please go ahead, sir.
Jonathan Kirshenbaum
Thank you, operator. Good morning, everyone, and welcome to the Kiniksa Pharmaceuticals Third Quarter 2026 Earnings Call. A press release highlighting our financial results and recent portfolio execution can be found on our website under the Investors section.
As for the agenda, our Chief Executive Officer, Sanj K. Patel, will start with an introduction. From there, Ross Moat, our Chief Operating Officer, will provide an update on ARCALYST commercial execution. After that, Mark Ragosa, our Chief Financial Officer, will review our third quarter 2026 financial results. And finally, Sanj will return at the end of the call to share closing remarks and kick off the Q&A session, for which John Paolini, Kiniksa's Chief Medical Officer, will also be on the line.
Before getting started, please note that we will be making forward-looking statements today that are subject to risks and uncertainties that may cause actual results to differ materially from such statements. A review of these statements and risk factors can be found on this slide as well as under the caption Risk Factors contained in our SEC filings. These statements speak only as of the date of this presentation, and we undertake no obligation to update such statements, except as required by law.
With that, I'll turn it over to Sanj.
Sanj Patel
Thanks, Jonathan, and good morning or good afternoon, everyone. Over the last 10, 11 years, we've built this company through multiple stages of growth. And today, I'm as excited as ever about what the team and I can accomplish together in the years ahead. Kiniksa continues to build a leading IL-1 alpha and beta inhibition franchise, driven by the commercialization of ARCALYST in recurrent pericarditis as well as our progress with KPL-387 and KPL-1161. This morning, we announced via a press release that we've raised our full year revenue guidance to between $1.045 billion and $1.050 billion. We continue to see robust growth with ARCALYST in recurrent pericarditis driven by strong execution and strategic investments across the business.
On the clinical side, we're excited about the progress of KPL-387 and KPL-1161. The pivotal Phase III study with KPL-387 continues to enroll and dose patients. We announced today that we expect data from this trial in the second half of 2027. The team and I are really looking forward to potentially launching this drug in the '28, '29 time frame. In addition to providing an important treatment option for patients with recurrent pericarditis, we believe KPL-387 could help grow the market by enabling a once-monthly subcu dosing. We're also on track to have KPL-1161, our quarterly IL-1 alpha and beta inhibitor in a Phase I clinical trial by the end of this year. Importantly, Kiniksa's robust financial profile allows us to continue to invest in penetrating the recurrent pericarditis market and growing the IL-1 alpha and beta inhibition franchise, whilst also pursuing additional value-creating opportunities.
In the third quarter, we saw a continuation of strong ARCALYST momentum with Q3 revenue of $286 million. The penetration rate into the annual population of 14,000 multiple recurrence patients increased to 23% as of the end of Q3. As shown by the increased breadth and depth of prescribing over time, adoption of IL-1 alpha and beta inhibition continues to expand among the approximately 40,000 recurrent pericarditis patients each year. The underlying fundamentals that propelled our commercial success remains strong. Since launch, we've observed robust payer approval, strong patient compliance and greater appreciation of the need to treat throughout the multiyear duration of the disease. Underpinning this growth is strong execution by our commercial organization and data-driven investments in ARCALYST.
Our AI supported patient identification initiatives and targeted direct-to-consumer campaign, Heart's Home, have positively contributed to growing patient and physician awareness of recurrent pericarditis and the important role of IL-1 alpha and beta inhibition in controlling this debilitating disease. As you've heard, we now expect ARCALYST to achieve over $1 billion in revenue in 2026, and we look forward to continuing to bring this blockbuster drug to more patients suffering from this debilitating disease. In order to grow the recurrent pericarditis market over the next several years, we plan to drive greater adoption in both the 14,000 multiple recurrence patients annually and the additional 26,000 patients annually that are experiencing their first recurrence. Kiniksa is executing against its strategy to help more patients, drive more ARCALYST growth and advance KPL-387 and KPL-1161. This trajectory will help put the company on a path to having multiple commercial products, continued strong and profitable growth and the flexibility to invest in future value creation. I can tell you that the team and I won't rest until we've helped many, many more patients.
And now our President and COO, Ross Moat.
Ross Moat
Thank you, Sanj. As you've heard, we're pleased with the continued strength of our commercial performance with ARCALYST, and we are even more excited by the substantial growth opportunity ahead. We continue to be highly focused on further increasing the penetration rate into the many thousands of recurrent pericarditis patients and continuing to evolve the treatment paradigm towards interleukin-1 alpha and beta inhibition.
As illustrated on the left side of this slide, physicians continue to report an increasing consideration of ARCALYST earlier in the disease course, including at the first recurrence. Additionally, we also see a growing appreciation for ARCALYST to be utilized earlier in the line of therapy, meaning after NSAIDs and colchicine and importantly, prior to corticosteroids as ratified in the 2025 American College of Cardiology concise clinical guidance for recurrent pericarditis. In fact, approximately 50% of physicians surveyed now support this treatment approach, representing a doubling from levels over the last 3 years prior to the publication of this independent guidance.
As we continue to build and lead this market, our team are laser-focused on value-driven investments that aim to increase market penetration and help many more patients. Increasing education and awareness on recurrent pericarditis, ARCALYST and the new treatment paradigm remain critical components of our strategy, and we've enhanced our capabilities through the use of AI and machine learning to reach a larger audience. On the health care professional side, we've done this through improving our data sources to inform us not only which health care professionals we should be seeing, but importantly, when we should be seeing them. On the patient side, we've seen encouraging early indicators from our Heart's Home direct-to-consumer campaign. Based on this initial traction, we plan to expand the campaign with additional content and outreach initiatives aimed at empowering more patients to engage with their health care professionals about ARCALYST.
As a reminder, Heart's Home is a highly targeted DTC campaign where we've innovated from traditional DTC by using AI to produce and deliver a campaign that's effective for a rare disease audience. This campaign is aimed at educating an enriched population of likely recurrent pericarditis patients who are currently not taking ARCALYST and empowering them to discuss ARCALYST with their health care provider. As an early indicator of the impact of this campaign, we've seen a 12-fold increase in the traffic to our ARCALYST website compared to baseline levels prior to the campaign. Additionally, there's been an eightfold increase with engaged sessions, meaning visits where the individual spends meaningful time on the website or interacts with the content. More importantly, approximately 55% of patients who saw the ad strongly agreed that they are motivated to speak with their healthcare provider about ARCALYST.
All of these indicators are strong signals that our digital strategy is reaching the right audience and is empowering action. As this disease has a very high annual incidence rate of patients coming into the labeled indication, this DTC initiative is nicely supplementing our robust execution in the field and helps us to address the substantial opportunity that we have ahead to help many more patients. As previously mentioned, our interleukin-1 alpha and beta inhibition franchise is growing, is profitable and has significant opportunity in the months and years ahead.
With that, I'll turn the call over to Mark to review our financial results.
Mark Ragosa
Thanks, Ross. Our third quarter delivered continued ARCALYST sales growth, advancement of KPL-387 and KPL-1161 development and a solid financial position. This morning, I'll review our financial results and key performance drivers. Detailed financial information is available in today's press release.
Starting with the income statement, ARCALYST revenue grew 58% year-over-year to $286 million in the third quarter, driven by continued gains in patient and physician adoption. Operating expenses increased year-over-year, driven by higher ARCALYST revenue, which resulted in additional cost of goods sold and collaboration expenses, advancement of KPL-387 development, which drove additional R&D investment and support of ARCALYST's commercialization to reach more patients, which led to additional SG&A investment. Operating income rose to $54.2 million and net income to $47.3 million, both up significantly year-over-year.
Turning to the calculation of ARCALYST collaboration profit, which drives total collaboration expenses on our income statement. ARCALYST's collaboration profit increased 67% year-over-year to $211.6 million, outpacing sales growth and reflecting disciplined commercial investment. Next, we ended the third quarter with $568.8 million in cash, reflecting approximately $43 million in net cash generation during the quarter.
Looking ahead, in addition to our updated 2026 ARCALYST sales guidance of $1.045 billion to $1.050 billion, we are providing full year R&D and SG&A expense guidance. We expect full year R&D expenses of $160 million to $170 million in 2026. This range includes continued development of KPL-387 and KPL-1161 as well as significant fourth quarter KPL-387 pre-commercial manufacturing costs. We expect full year SG&A expenses of $270 million to $280 million in 2026. This range supports continued ARCALYST commercialization, including additional personnel and promotional activities in the fourth quarter to further build disease awareness and enhance patient and physician targeting.
In closing, our third quarter results show the strength of our operating plan, a growing and profitable ARCALYST business, funding the advancement of key development assets and positioning us to create value in the near and long term.
With that, I'll turn the call back to Sanj for closing remarks.
Sanj Patel
Thanks, Mark. As you've heard, Kiniksa is generally well positioned to build significant future value as we grow our IL-1 alpha and beta inhibition franchise. The team and I are on it and focused on helping as many patients as possible with ARCALYST and to advancing the development of our clinical portfolio in order to bring additional therapies to patients.
With that, I'll turn it back to the operator for questions. Thank you.
Operator
And our first question for today comes from the line of Anupam Rama from JPMorgan.
分析师问答
Anupam Rama
Congrats on the quarter. I just wanted to ask a quick KPL-387 question. I think the guidance for pivotal data in the second half of 2027 is new today. So can you tell us what you're seeing in terms of enrollment dynamics and where you are on site initiation that give you confidence to laying out this time line?
Sanj Patel
Thanks, Anupam. I think John Paolini will answer that. Suffice to say that our execution across not just commercial but also the clinical development organization. And as I've said before, we are enrolling and dosing patients. It's a global clinical study with global sites. And both myself, John and Ross take pride in meeting with investigators and just getting them excited about the future. So there's been some massive momentum, both internally and with our investigators. And as with ever, we go at things with full force, and that's what the guidance is around as having results in the second half of next year. But John?
John Paolini
I think that's excellent guidance from Sanj. The only thing that I would add is that on clinicaltrials.gov, you can see the extent of the global nature of our program. And so the sites that are involved in the program across the world are all listed there. And so you can see the scope of effort. And as Sanj mentioned, we are on the ground and engaging with clinicians, and we can feel the excitement about the program, and so we continue forward.
Sanj Patel
I'd also say we have a crack clinical operations team and having run clinical operations for many years at Genzyme before I run commercial, I've got a very high bar for clinical research and clinical operations. And after many, many years, I feel like we've really got the best team to do the job.
Operator
And our next question comes from the line of Edward Nash from Canaccord Genuity.
Edward Nash
Really excited to see that over $1 billion number now for the guidance. So congratulations. I just wanted to ask now you're at 23% active penetration, that's 2% higher than last quarter, which is really, I think, impressive. Can you maybe give us an idea of how we should think about the shape of the penetration curve from here? Is there anything structurally different about the next quartile of patients versus the patients you've already converted? You're going up on the SG&A number, which makes a lot of sense. And you put a lot of focus on the DTC campaign, which clearly seems to be paying off. Just kind of curious as to how many extra dollars need to be put in to kind of achieve greater uptake of scripts.
Ross Moat
Thanks, Edward. This is Ross. So thanks very much for your comments. And yes, we're pleased to announce that we were around 23% at the end of the quarter in terms of penetration into the multiple recurrence group, which is the patients that have suffered for 2 or more recurrences. And that's without allocating anything to the first recurrence group, which we've got about 20% of our prescriptions in the first recurrence group also. So the opportunity is very significant. While on one hand, we're happy with the 23%, and that's obviously showing a couple of percent growth versus the end of Q2 number when we shared it. The time before that, the last time we shared the penetration number, I think it was at the end of Q4, which was 18% at the end of last year. So that's been growing relatively nicely. But I think more importantly is the opportunity that's ahead. I mean, clearly, there are a lot of patients in the 2-plus recurrence group that we still got to help and as I said, not allocating for even those that are in the first recurrence. And as we shared from some of the market research today, the propensity and the desire for physicians to look and treat patients with IL-1 alpha and beta inhibition in the first group has also been growing quite substantially over time. So we think the future is very bright from that perspective.
In terms of kind of different patient groups, aside from the recurrence number, there's really not much else to report. We're not seeing a significant change necessarily in the demographics of the patients or severity levels or anything else. It's just that this is a rare flare in cardiovascular disease. There are a lot of patients out there relative to a rare disease. And we're trying to get out and reach as many patients as possible. We know that they are widely dispersed around the country, and that takes a certain effort, as you have alluded to, from our sales and marketing spend and so on. But our efforts are ultimately on value-driven investments that can make sure we reach those physicians and switch more and more of them on to this new way of treating and ultimately get greater penetration into this opportunity to ultimately help more patients.
Edward Nash
I'm sorry, go ahead.
Ross Moat
Yes. No, Edward, maybe just to add the final part as well is that the DTC spend and field team spend that we have, and we've announced in our guidance looking forward as well is ultimately very efficient. We are very focused on this as a rare disease market. And for the DTC side of things, this is not kind of broad spectrum massive spend DTC. It's very efficient, very targeted type of expenditure to address appropriately the market that we have.
Operator
And our next question comes from the line of Paul Choi from Goldman Sachs.
Kyuwon Choi
Congratulations on the great quarter, and congrats Ross as well on the new title. I want to ask on the 387 switch strategy. And I was wondering if you could just sort of provide a little more color on where you are with progress on that. And I guess what the ultimate data you are looking for there to support 387 from an insurance perspective?
And my second question is on 1161. Maybe just where are you thinking in terms of indication selection, I guess, at this point and a little bit more on the criteria that you're considering for the first indication there for 1161?
John Paolini
Thank you, Paul. I appreciate your questions. This is John. So with regard to the KPL-387 transition to monotherapy dosing and administration study, I mean, this study is designed primarily as what we call a posology study. So it covers dosing administration specifically for informing the label. So it's designed, as you can see in the slides, for looking at how patients are coming from stable therapies, whether they're oral or biologic and then transitioning to KPL-387 monotherapy at the 300-milligram subcutaneous monthly dose level. And so that's really what that study is designed to do. It follows very similarly the precedent of what's in the ARCALYST label, which similarly describes the transitions from NSAIDs, colchicine, corticosteroids and anakinra. So this is just really following in that tradition. So that's how the study is designed and the data that will be generated.
But I'll turn it over to Ross to talk about ultimately other elements of transition.
Ross Moat
Yes. Thanks very much, John. I mean, I guess just to say that, obviously, we're very excited about the potential for KPL-387, but everything is kind of data dependent as we move forward. But when we tested the target product profile for KPL-387, both with health care professionals and patients, we were really very encouraged by the feedback that we had back while we believe that ARCALYST has a lot of growth left in it to address the recurrent pericarditis opportunity. With KPL-387, patients did tell us that around 75% of them would prefer the KPL-387 target profile being a monthly liquid formulation, potentially autoinjector over current commercial or other investigational therapies. They also reported a propensity for a greater number of patients to start on therapy with that target product profile as well as staying on therapy longer. And then when you looked at the health care professional side, 92% of health care professionals indicated a high likelihood to prescribe KPL-387 with that target product profile over available commercial or other investigational therapies. So that, I think, reads quite positively about the future. But ultimately, we are focused on conducting the clinical research and awaiting the data.
John Paolini
And then with regard to your question about 1161, so we're very excited about this program, which has the potential for once quarterly dosing, again, targeting the IL-1 alpha and beta signaling by targeting the receptor. And so this program, we expect to begin a Phase I program by the end of the year. And to that extent, we have not yet announced or disclosed our plans with regard to development indications. Suffice it to say, though, that with that longer duration of action, that really unlocks a lot of potential for disease states, especially those that are chronic or lifelong in nature by virtue of the once-quarterly dosing.
Ross, anything to add?
Ross Moat
No. That's great.
Operator
And our next question comes from the line of Roger Song from Jefferies.
Unknown Analyst
This is Peter calling in for Roger. Congrats on a good quarter. Just a couple of quick ones from us. For third quarter, can you tell us what share of the new patients came from first time versus repeat prescribers? And can you also share whether -- or how much growth you've seen within the first recurrence patients as well for this quarter?
Ross Moat
Yes. Peter, thanks very much for the questions. We don't share some of that data directly externally. But of course, it's the type of thing that we look at a lot internally in the business. What we have shared is in Q3, clearly, we've seen a substantial uplift in the number of patients, representing a strong growth of $42.5 million quarter-on-quarter. And ultimately, that's driven by strong prescriber growth.
What we have said is that when you look at the total number of prescribers launched to date of ARCALYST for recurrent pericarditis in Q3 -- or I should say, at the end of Q3, we had around 5,450 total prescribers. Now that's an uplift of around 450 quarter-on-quarter. So again, really showing very strong growth. And now we have around 30% of that group who are repeat prescribers, which is up by around 170 prescribers. Historically, we've said that the split between the first and second recurrence is about 80% of prescriptions in the second plus recurrence and 20% in the first, but we haven't updated that data on a very frequent basis as a lot of it comes from kind of ad hoc market research that we do. But clearly, we're showing pretty strong growth in Q3. And a lot of that is down to the refined targeting that we have with our field team, the DTC campaign in a very targeted approach and also just broader dissemination of the ACC concise clinical guidance and really just empowering physicians on this new way of treating the disease.
Operator
And our next question comes from the line of Geoff Meacham from Citi.
Geoffrey Meacham
Great job on the quarter. Just have a couple of quick ones. The first on 387, I know convenience angle, obviously, is a big differentiator. But beyond that, is there a patient maybe on ARCALYST today that you think is particularly suited to transition to 387 just on convenience, I know clinically, maybe those that live further away or what are the attributes of the patients, I guess, is the question that would maybe more rapidly switch?
And then bigger picture question, just on the cash and the capital deployment. You guys have been consistently profitable. You're building some cash on the balance sheet. I don't know, just trying to think of ways to maximize value from a balance sheet cash flow context? Like what are you thinking about from a BD perspective? Where does this fall in your priorities?
John Paolini
Thank you, Geoff, for your question. I'll tackle this first part with regard to the transition, if you will, from ARCALYST to KPL-387. I mean I think that our position with regard to the management of the disease is that blockade of IL-1 alpha and IL-1 beta is critical to maintaining disease control and to gaining the disease control as a monotherapy. And so in that sense, we're particularly excited about the KPL-387 program because it adds to the optionality of what's available to patients and physicians in terms of treating this disease. And so that efficacy ultimately remains to be demonstrated in the Phase III pivotal trial, which is ongoing. But importantly, what we have going on as well is the 212 study or the KPL-387 transition to monotherapy dosing and administration study, which is really designed to look at the mechanics of how to transition from one existing therapy to KPL-387 monotherapy, the 300-milligram monthly dose level. And so that includes NSAIDs and colchicine, corticosteroids or IL-1 pathway inhibitors, including anakinra and rilonacept. And all of those different transition regimens are studied and are evaluated in the study and then go on to over a 16-week primary endpoint period. So it's really about that transition. And that then informs the label with regard to telling or informing physicians how they can make that transition. But in terms of the patient profile, it's really about the optionality for the patient and the physician to choose which therapy, which effective therapy is considered to be best for them.
Sanj Patel
And Geoff, in regards to your question on maximizing the value and cash position. I mean I can tell you what drives us each and every day is the potential to increase that overall maximum value. There's so much kinetic energy within the company that's focused on that. We've talked about, obviously, today, the growth with ARCALYST, and we continue to be very excited about the future potential there. We talked about the latest penetration rate being in some ways only 23%. But equally, obviously, across the development portfolio with KPL-387 and 1161 as we've talked about, we're moving now into obviously the Phase III pivotal study for 387, being very excited about being in the clinic with 1161 later this year.
But as you see, those latter 2 programs were homegrown. We continue to look at other additional value-creating opportunities, both internally but also externally. I think we've been very judicious and very thoughtful about capital allocation. We do look at BD opportunities. But as you can imagine, with our commercial products, with our pipeline, the bar is exceedingly high. That said, we are very pragmatic bunch, and we do look at where the value could come from all the time. It's what drives us essentially. So rest assured, we know how to capital allocate. We know it best to drive value, and we'll continue doing that and ultimately keep executing.
Operator
This does conclude the question-and-answer session of today's program. I'd like to hand the program back to Sanj K. Patel, CEO, for any further remarks.
Sanj Patel
