 1. What work did the SIG do this year that should be highlighted?
 
-<!--
-   Some example items that might be worth highlighting:
-   - Major KEP advancement
-   - Important initiatives that aren't tracked via KEPs
-   - Paying down significant tech debt
-   - Governance and leadership changes
--->
+Notable work we produced in 2024 includes:
+- Helping validate scalability/performance impact and reliability for many features across the year as well as preventing regressions
+- Enhancements to our scalability test framework around better instrumentation and reduction in flakiness
+- Additional test coverage spanning across the Kubernetes project
+- Driving/influencing a bunch of KEPs and fixes, mainly within Kubernetes core (API server, API machinery, etcd and kube-controller-manager)
 
 2. Are there any areas and/or subprojects that your group needs help with (e.g. fewer than 2 active OWNERS)?
 
+Overall in 2024 we have had healthy contributions from multiple companies (see these [devstats](https://k8s.devstats.cncf.io/d/8/company-statistics-by-repository-group?orgId=1&var-period=d7&var-metric=contributions&var-repogroup_name=SIG%20Scalability&var-repo_name=kubernetes%2Fkubernetes&var-companies=All&from=1672560000000&to=1704095999000).
+We continue to seek help from various SIGs to force-multiply scalability test coverage and regression hunting for features/components they own. We also encourage them to proactively identify and document SLIs/SLOs/limits for APIs and workflows they own. This allows each SIG to set a scalability bar for their systems (just like up-time/availability) and thereby make scalability a first class citizen of Kubernetes and related CNCF projects. As always, SIG scalability is eager to assist/guide with this process.
 
 3. Did you have community-wide updates in 2024 (e.g. KubeCon talks)?
 
-<!--
-  Examples include links to email, slides, or recordings.
--->
+We presented SIG Scalability Intro + Deep-Dive updates at EU KubeCon:
+- [KubeCon Paris](https://kccnceu2024.sched.com/event/1Yhgs/intro-deep-dive-kubernetes-sig-scalability-wojciech-tyczynski-google-shyam-jeedigunta-amazon-web-services)

 4. KEP work in 2024 (v1.30, v1.31, v1.32):
-<!--
-   TODO: Uncomment the following auto-generated list of KEPs, once reviewed & updated for correction.
 
-   Note: This list is generated from the KEP metadata in kubernetes/enhancements repository.
-      If you find any discrepancy in the generated list here, please check the KEP metadata.
-      Please raise an issue in kubernetes/community, if the KEP metadata is correct but the generated list is incorrect.

+Notable KEPs, mostly co-owned with SIG API machinery and SIG etcd:
+- [2340 - Consistent Reads from Cache](https://github.com/kubernetes/enhancements/tree/master/keps/sig-api-machinery/2340-Consistent-reads-from-cache)
+  - Beta in 1.31
+- [3157 - Streaming List](https://github.com/kubernetes/enhancements/tree/master/keps/sig-api-machinery/3157-watch-list)
+  - Beta in 1.32
+- [4222 - CBOR Serializer](https://github.com/kubernetes/enhancements/tree/master/keps/sig-api-machinery/4222-cbor-serializer)
+  - Alpha in 1.32
+- [4568 - Resilient watchcache initialization](https://github.com/kubernetes/enhancements/tree/master/keps/sig-api-machinery/4568-resilient-watchcache-initialization)
