Background

背景

On 28 March 2024, the boards of directors of Keysight Technologies, Inc. ("Keysight") and Spirent Communications plc (London Stock Exchange Symbol: SPT) ("Spirent") announced that they had reached agreement on the terms and conditions of a recommended cash acquisition of the entire issued and to be issued ordinary share capital of Spirent by Keysight (the "Acquisition"). The Acquisition is to be implemented by means of a Court-sanctioned scheme of arrangement under Part 26 of the Companies Act 2006 (the "Scheme"). The scheme document in relation to the Scheme was published on 25 April 2024 (the "Scheme Document").

2024年3月28日，Keysight Technologies, Inc.（"Keysight"）和 Spirent Communications plc（伦敦证券交易所代码：SPT）（"Spirent"）的董事会宣布，他们已就 Keysight 对 Spirent 全部已发行和待发行普通股本的推荐现金收购达成协议（"收购"）。该收购将通过根据 2006 年公司法第 26 部分的法院批准安排方案实施（"方案"）。与该方案相关的方案文件于2024年4月25日发布（"方案文件"）。

On 9 September 2025, Keysight and Spirent announced that they had agreed, with the consent of the Panel and subject to the approval of the Court, to extend the Long Stop Date for the Scheme to become unconditional and effective from 29 September 2025 to 27 October 2025 (the "Long Stop Date Extension").

2025年9月9日，Keysight 和 Spirent 宣布，他们已在面板的同意下，并在法院批准的前提下，同意将方案的最后截止日期从2025年9月29日延长至2025年10月27日（"最后截止日期延长"）。

On 15 September 2025, Keysight and Spirent announced that the Court hearing on 16 September 2025 would be used to consider Spirent's application to the Court in respect of the Long Stop Date Extension.

2025年9月15日，Keysight 和 Spirent 宣布，2025年9月16日的法院听证会将用于审议 Spirent 关于最后截止日期延长的申请。

Approval of the Long Stop Date Extension

最后截止日期延长的批准

Further to such announcements, Keysight and Spirent confirm that the Court has approved the Long Stop Date Extension. A copy of the order of the Court approving the extension will be made available on Spirent's website at https://corporate.spirent.com/ and Keysight's website at https://www.investor.keysight.com/.

根据上述公告，Keysight 和 Spirent 确认法院已批准最后截止日期的延长。法院批准延长的命令副本将在 Spirent 的网站 https://corporate.spirent.com/和 Keysight 的网站 https://www.investor.keysight.com/上发布。

Keysight continues to believe that SAMR's review of the Acquisition is in its final stages and that the parties will receive SAMR Clearance shortly.

Keysight 继续相信，SAMR 对收购的审查已进入最后阶段，双方将很快获得 SAMR 的批准。

Next steps

Further announcements will be made as appropriate.

将根据需要发布进一步公告。

Completion of the Acquisition remains subject to the satisfaction or (if capable of waiver) waiver of the remaining conditions to the Acquisition set out in Part III of the Scheme Document (the "Conditions") including the Condition relating to sanction of the Scheme by the Court. The parties continue to keep the timetable under close review and will provide any updates as required.

收购的完成仍需满足或（如可放弃）放弃方案文件第 III 部分中列出的收购剩余条件（"条件"），包括法院对方案的批准条件。各方继续密切关注时间表，并将在需要时提供任何更新。

The Court's approval of the extension was granted without prejudice to the ability of any Spirent Shareholder to argue at the Court Sanction Hearing that the extension should not have been granted.

法院对延长的批准是在不影响任何 Spirent 股东在法院批准听证会上主张不应批准延长的能力的情况下授予的。

Capitalised terms used but not defined in this announcement have the meanings given to them in the Scheme Document.

The release, publication, or distribution of this announcement in or into certain jurisdictions other than the UK may be restricted by law. Persons who are not resident in the UK or who are subject to other jurisdictions should inform themselves of, and observe, any applicable requirements.

在英国以外的某些法域发布、公布或分发本公告可能受到法律限制。非英国居民或受其他法域约束的人士应自行了解并遵守任何适用的要求。

Unless otherwise determined by Keysight or required by the Takeover Code, and permitted by applicable law and regulation, the Acquisition shall not be made available, directly or indirectly, in, into, or from a Restricted Jurisdiction where to do so would violate the laws in that jurisdiction and no person may vote in favour of the Acquisition by any such use, means, instrumentality or form within a Restricted Jurisdiction or any other jurisdiction if to do so would constitute a violation of the laws of that jurisdiction. Accordingly, copies of this announcement and all documents relating to the Acquisition are not being, and must not be, directly or indirectly, mailed or otherwise forwarded, distributed, or sent in, into, or from a Restricted Jurisdiction where to do so would violate the laws in that jurisdiction, and persons receiving this announcement and all documents relating to the Acquisition (including custodians, nominees, and trustees) must not mail or otherwise distribute or send them in, into, or from such jurisdictions where to do so would violate the laws in that jurisdiction. To the fullest extent permitted by applicable law, the companies and persons involved in the Acquisition disclaim any responsibility or liability for the violation of such restrictions by any person.

除非 Keysight 另有决定或根据收购守则的要求，并且符合适用的法律和法规，收购不得直接或间接地在限制性司法管辖区内、进入或来自该区域进行，因这样做将违反该司法管辖区的法律，任何人不得通过在限制性司法管辖区内或任何其他司法管辖区内的任何此类使用、手段、工具或形式投票支持收购，如果这样做将构成对该司法管辖区法律的违反。因此，本公告及与收购相关的所有文件不得直接或间接地邮寄或以其他方式转发、分发或发送至限制性司法管辖区，因这样做将违反该司法管辖区的法律，接收本公告及与收购相关的所有文件的人（包括保管人、提名人和受托人）不得在此类司法管辖区内邮寄或以其他方式分发或发送这些文件，因这样做将违反该司法管辖区的法律。在适用法律允许的最大范围内，参与收购的公司和个人对任何人违反此类限制不承担任何责任或义务。

The availability of the Acquisition to Spirent Shareholders who are not resident in the UK may be affected by the laws of the relevant jurisdictions in which they are resident. Persons who are not resident in the UK should inform themselves of, and observe, any applicable requirements.

Additional Information for US Investors

美国投资者的附加信息

The Acquisition relates to shares of a UK company and is proposed to be effected by means of a scheme of arrangement under the laws of England and Wales. A transaction effected by means of a scheme of arrangement is not subject to the tender offer rules or the proxy solicitation rules under the US Exchange Act.

收购涉及一家英国公司的股份，拟通过根据英格兰和威尔士法律的安排方案进行。通过安排方案进行的交易不受美国证券交易法下的要约收购规则或代理征求规则的约束。

Accordingly, the Acquisition is subject to the disclosure and procedural requirements applicable in the UK to schemes of arrangement which differ from the disclosure requirements of US tender offer and proxy solicitation rules.

因此，收购受适用于英国安排方案的披露和程序要求的约束，这些要求与美国要约收购和代理征求规则的披露要求不同。

Neither the US Securities and Exchange Commission nor any US state securities commission has approved or disapproved or passed judgment upon the fairness or the merits of the Acquisition or determined if this announcement is adequate, accurate or complete. Any representation to the contrary is a criminal offence in the US.

美国证券交易委员会或任何美国州证券委员会均未批准或否决收购的公平性或优点，也未确定本公告是否充分、准确或完整。任何相反的陈述在美国都是犯罪行为。

However, if Keysight were to elect to implement the Acquisition by means of a Takeover Offer, such Takeover Offer would in addition need to be made in compliance with any applicable US laws and regulations, including any applicable exemptions under the US Exchange Act. Such a takeover would be made in the US by Keysight and no one else.

然而，如果 Keysight 选择通过要约收购的方式实施收购，则该要约收购还需遵守任何适用的美国法律和法规，包括美国证券交易法下的任何适用豁免。这样的收购将由 Keysight 在美国进行，其他人不得参与。

In the event that the Acquisition is implemented by way of a Takeover Offer, in accordance with normal UK practice and pursuant to Rule 14e-5(b) of the US Exchange Act, Keysight or its nominees, or its brokers (acting as agents), may from time to time make certain purchases of, or arrangements to purchase, shares or other securities of Spirent outside the US, other than pursuant to such Takeover Offer, during the period in which such Takeover Offer would remain open for acceptance. These purchases may occur either in the open market at prevailing prices or in private transactions at negotiated prices. Any information about such purchases or arrangements to purchase shall be disclosed as required in the UK, shall be reported to a Regulatory Information Service and shall be available on the London Stock Exchange website at www.londonstockexchange.com.

如果收购通过要约收购的方式实施，根据正常的英国惯例和美国证券交易法第 14e-5(b) 条，Keysight 或其提名人或其经纪人（作为代理人）可能会不时在美国以外购买或安排购买 Spirent 的股份或其他证券，而不通过该要约收购，在该要约收购开放接受的期间内。这些购买可能在公开市场以现行价格进行，或在私下交易中以协商价格进行。关于这些购买或购买安排的任何信息将根据英国的要求披露，并将报告给监管信息服务，并将在伦敦证券交易所网站上提供，网址为 www.londonstockexchange.com。

根据正常的英国惯例，Keysight 或其提名人或经纪人（作为代理人）可能会不时购买或安排购买 Spirent 的股份或其他证券，而不通过收购，直到收购和/或方案生效、失效或以其他方式撤回的日期。如果进行此类购买或购买安排，它们将发生在公开市场以现行价格进行，或在私下交易中以协商价格进行。关于这些购买或购买安排的任何信息将根据英国的要求披露，并将报告给监管信息服务，并将在伦敦证券交易所网站上提供，网址为 www.londonstockexchange.com。

The receipt of consideration by a US shareholder or holder of Spirent ADRs pursuant to the Scheme will likely be a taxable transaction for US federal income tax purposes. Each Spirent Shareholder and Spirent ADR Holder is urged to consult their independent professional adviser immediately regarding the tax consequences of the Acquisition applicable to them, including under applicable US state and local, as well as overseas and other, tax laws.

根据方案，美国股东或 Spirent ADR 持有者收到的对价可能会被视为美国联邦所得税目的的应税交易。每位 Spirent 股东和 Spirent ADR 持有者都被敦促立即咨询其独立专业顾问，了解适用于他们的收购的税务后果，包括适用的美国州和地方税法，以及海外和其他税法。

Financial information relating to Spirent included in this announcement and the Scheme Document (or, if applicable, the Offer Document) has been or shall have been prepared in accordance with accounting standards applicable in the UK and may not be comparable to financial information of US companies or companies whose financial statements are prepared in accordance with generally accepted accounting principles in the US.

本公告和方案文件（或如适用，报价文件）中包含的与 Spirent 相关的财务信息已根据适用于英国的会计标准编制，可能与根据美国公认会计原则编制的美国公司或其他公司的财务信息不可比。

Spirent is organised under the laws of England and Wales. Some or all of the officers and directors of Spirent are residents of countries other than the US. In addition, most of the assets of Spirent are located outside the US. As a result, it may be difficult for US shareholders of Spirent and Spirent ADR Holders to effect service of process within the US upon Spirent or its officers or directors or to enforce against it a judgment of a US court predicated upon the federal or state securities laws of the US.

Spirent 根据英格兰和威尔士的法律组织。Spirent 的一些或全部高级职员和董事居住在美国以外的国家。此外，Spirent 的大部分资产位于美国以外。因此，Spirent 的美国股东和 Spirent ADR 持有者可能很难在美国对 Spirent 或其高级职员或董事进行送达程序，或根据美国的联邦或州证券法对其执行美国法院的判决。

Forward-looking Statements

前瞻性声明

This announcement (including information incorporated by reference in this announcement), oral statements made regarding the Acquisition, and other information published by Spirent, any member of the Spirent Group, Keysight, or any member of the Keysight Group, contain statements which are, or may be deemed to be, "forward-looking statements" as defined in the US Exchange Act and are subject to the safe harbours created therein. Such forward-looking statements are prospective in nature and are not based on historical facts, but rather on current expectations and on numerous assumptions regarding the business strategies and the environment in which Spirent, any member of the Spirent Group, Keysight, any member of the Keysight Group, or any member of the Combined Group shall operate in the future and are subject to risks and uncertainties that could cause actual results to differ materially from those expressed or implied by those statements.

本公告（包括本公告中引用的信息）、关于收购的口头声明以及 Spirent、Spirent 集团的任何成员、Keysight 或 Keysight 集团的任何成员发布的其他信息，包含被视为或可能被视为美国《证券交易法》定义的 “前瞻性声明” 的内容，并受其中创建的安全港保护。这些前瞻性声明具有前瞻性，基于当前的期望和关于 Spirent、Spirent 集团的任何成员、Keysight、Keysight 集团的任何成员或合并集团的任何成员未来运营的众多假设，而非基于历史事实，并且面临可能导致实际结果与这些声明所表达或暗示的结果存在重大差异的风险和不确定性。

The forward-looking statements contained in this announcement may relate to Spirent, any member of the Spirent Group, Keysight, any member of the Keysight Group, or any member of the Combined Group's future prospects, developments and business strategies, the expected timing and scope of the Acquisition and other statements other than historical facts. In some cases, these forward-looking statements can be identified by the use of forward-looking terminology, including the terms "believes", "estimates", "will look to", "would look to", "plans", "prepares", "anticipates", "expects", "is expected to", "is subject to", "budget", "scheduled", "forecasts", "synergy", "strategy", "goal", "cost saving", "projects" "intends", "assumes", "may", "will", "shall" or "should" or their negatives or other variations or comparable terminology. Forward-looking statements may include statements relating to the following: (i) future capital expenditures, expenses, revenues, earnings, synergies, economic performance, indebtedness, financial condition, dividend policy, losses and future prospects; (ii) business and management strategies and the expansion and growth of Spirent, any member of the Spirent Group, Keysight, any member of the Keysight Group, or any member of the Combined Group's operations and potential synergies resulting from the Acquisition; and (iii) the effects of global economic conditions and governmental regulation on Spirent, any member of the Spirent Group, Keysight, any member of the Keysight Group, or any member of the Combined Group's business.

本公告中包含的前瞻性声明可能涉及 Spirent、Spirent 集团的任何成员、Keysight、Keysight 集团的任何成员或合并集团的任何成员的未来前景、发展和商业战略、收购的预期时间和范围以及其他非历史事实的声明。在某些情况下，这些前瞻性声明可以通过使用前瞻性术语来识别，包括 “相信”、“估计”、“将寻求”、“会寻求”、“计划”、“准备”、“预期”、“期望”、“预计”、“受制于”、“预算”、“计划”、“预测”、“协同效应”、“战略”、“目标”、“节省成本”、“项目”、“打算”、“假设”、“可能”、“将”、“应” 或其否定形式或其他变体或可比术语。前瞻性声明可能包括与以下内容相关的声明：（i）未来的资本支出、费用、收入、收益、协同效应、经济表现、债务、财务状况、股息政策、损失和未来前景；（ii）Spirent、Spirent 集团的任何成员、Keysight、Keysight 集团的任何成员或合并集团的任何成员的业务和管理战略以及扩展和增长的运营及收购带来的潜在协同效应；以及（iii）全球经济状况和政府监管对 Spirent、Spirent 集团的任何成员、Keysight、Keysight 集团的任何成员或合并集团的任何成员业务的影响。

By their nature, forward-looking statements involve risk and uncertainty because they relate to events and depend on circumstances that shall occur in the future. These events and circumstances include changes in the global, political, economic, business, competitive, market and regulatory forces, future exchange and interest rates, changes in tax rates and future business combinations or disposals. If any one or more of these risks or uncertainties materialise or if any one or more of the assumptions prove incorrect, actual results may differ materially from those expected, estimated or projected. Such forward-looking statements should, therefore, be construed in light of such factors.

由于其性质，前瞻性声明涉及风险和不确定性，因为它们与将来发生的事件和依赖于将来发生的情况有关。这些事件和情况包括全球、政治、经济、商业、竞争、市场和监管力量的变化、未来的汇率和利率、税率的变化以及未来的商业合并或处置。如果这些风险或不确定性中的任何一个或多个实现，或者这些假设中的任何一个或多个被证明不正确，实际结果可能与预期、估计或预测的结果存在重大差异。因此，应根据这些因素来解读这些前瞻性声明。

None of Spirent, any member of the Spirent Group, Keysight, nor any member of the Keysight Group, nor any member of the Combined Group, nor any of their respective associates or directors, officers or advisers, provides any representation, assurance or guarantee that the occurrence of the events expressed or implied in any forward-looking statements in this announcement shall actually occur. Given these risks and uncertainties, potential investors should not place any reliance on forward-looking statements.

Spirent、Spirent 集团的任何成员、Keysight、Keysight 集团的任何成员、合并集团的任何成员及其各自的关联方、董事、高级职员或顾问，均不对本公告中任何前瞻性声明所表达或暗示的事件的发生提供任何陈述、保证或担保。鉴于这些风险和不确定性，潜在投资者不应依赖前瞻性声明。

Specifically, statements of estimated cost savings and synergies relate to future actions and circumstances which, by their nature, involve risks, uncertainties, and contingencies. As a result, the cost savings and synergies referred to may not be achieved, may be achieved later or sooner than estimated, or those achieved could be materially different from those estimated. Due to the scale of the Combined Group, there may be additional changes to the Combined Group's operations. As a result, and given the fact that the changes relate to the future, the resulting cost synergies may be materially greater or less than those estimated.

具体而言，关于预计节省成本和协同效应的声明涉及未来的行动和情况，这些情况本质上涉及风险、不确定性和偶然性。因此，提到的节省成本和协同效应可能无法实现，可能比预计的时间更晚或更早实现，或者实现的结果可能与预计的结果存在重大差异。由于合并集团的规模，合并集团的运营可能会发生额外变化。因此，考虑到这些变化与未来相关，最终的成本协同效应可能大大高于或低于预计的水平。

The forward-looking statements speak only at the date of this announcement. All subsequent oral or written forward-looking statements attributable to Spirent, any member of the Spirent Group, Keysight, or any member of the Keysight Group, or any member of the Combined Group, or any of their respective associates, directors, officers, employees, or advisers, are expressly qualified in their entirety by the cautionary statement above.

前瞻性声明仅在本公告日期有效。所有后续的口头或书面前瞻性声明，归因于 Spirent、Spirent 集团的任何成员、Keysight 或 Keysight 集团的任何成员、合并集团的任何成员或其各自的关联方、董事、高级职员、员工或顾问，均明确完全受到上述警示声明的限制。

Spirent, any member of the Spirent Group, Keysight, any member of the Keysight Group and any member of the Combined Group expressly disclaim any obligation to update such statements other than as required by law or by the rules of any competent regulatory authority, whether as a result of new information, future events, or otherwise.

Spirent、Spirent 集团的任何成员、Keysight、Keysight 集团的任何成员和合并集团的任何成员明确声明，除法律或任何主管监管机构的规则要求外，没有义务更新这些声明，无论是由于新信息、未来事件还是其他原因。

No Profit Forecasts or Estimates

没有利润预测或估计

No statement in this announcement is intended as a profit forecast or estimate for any period and no statement in this announcement should be interpreted to mean that earnings or earnings per share for Keysight or Spirent, as appropriate, for the current or future financial years would necessarily match or exceed the historical published earnings or earnings per share for Keysight or Spirent, as appropriate.

本公告中的任何声明均不意图作为任何期间的利润预测或估计，且本公告中的任何声明不应被解读为意味着 Keysight 或 Spirent（视情况而定）在当前或未来财务年度的收益或每股收益必然会与 Keysight 或 Spirent（视情况而定）历史公布的收益或每股收益相匹配或超过。
